MLCC Shortage 2026: Which Capacitors Are Hit and a 6-Point Substitution Check

The 2026 MLCC shortage is not hitting every capacitor on your BOM. As of September 2026, small-value C0G/NP0 and mid-range X7R parts in 0402 to 0805 cases are still quotable in weeks, while high-capacitance, automotive-grade and high-voltage MLCCs are the lines that stall a build. Yageo raised prices across its entire capacitor portfolio on 1 July 2026, Murata raised prices on multilayer inductor and ferrite bead lines on 1 April 2026, and high-specification MLCC lead times reported in August 2026 run up to about 40 weeks. This guide shows how to find the at-risk lines on your own BOM and how to qualify a substitute without creating a field failure.

Which MLCCs are actually short in 2026

The shortage is concentrated in three MLCC groups: high-capacitance parts (roughly 10 µF and up in 0402 to 0805), AEC-Q200 automotive grades, and high-voltage or large-case parts. Everything else is tighter and dearer, but still buyable. The reason is physical: according to TrendForce's July 2026 report on the Yageo increase, a high-capacitance MLCC needs 500 to 1,300 dielectric layers against 50 to 100 for a low-capacitance part, so every AI server board that absorbs high-layer capacity removes far more factory time than its unit count suggests.

Use this table to sort your BOM before you call a single supplier. Lead times are the ranges reported for August 2026 by distributors and Korean trade press; treat them as direction, not a quote.

If a line sits in the bottom four rows, it belongs on a watch list with a named alternate. If it sits in the top two, a price review is usually enough. For the wider picture across ICs and memory, see our analysis of the 2026 semiconductor shortage for European OEMs.

What changed in pricing this year

Three price moves define 2026 so far. First, Murata confirmed an increase effective 1 April 2026 on four multilayer lines (chip ferrite beads, ferrite power inductors, RF inductors and common mode choke coils), citing silver costs, with Murata, Samsung Electro-Mechanics and Taiyo Yuden all running above 80% utilisation. Second, Yageo applied new pricing from 1 July 2026 to MLCC, tantalum, polymer, aluminium electrolytic, film capacitors and supercapacitors, reportedly its first MLCC increase for direct customers, with official prices reported to rise by around 50%. Third, spot pricing moved faster than list pricing, and TrendForce reported some high-end parts rising far more within a single month.

For a European buyer the practical consequence is that a price agreed in spring may not survive a reorder in autumn. Distributor quotes now often carry a validity of days rather than weeks, and franchised channels place new orders into allocation instead of confirming a ship date.

Why automotive and industrial buyers in Europe feel it first

German and wider EU buyers feel the 2026 MLCC squeeze early because their BOMs lean on exactly the constrained grades: AEC-Q200 parts for vehicles, 125 °C X7R for drives and inverters, and high-voltage cases for power supplies. Automotive-qualified MLCCs come off separate, lower-throughput qualified lines, so a commercial part easing does not mean its automotive twin has. A second factor is qualification cost. A consumer design can swap a capacitor in a week; an automotive or medical design may need a PPAP update or a change notice to the customer, which is why an alternate must be approved before the shortage reaches your line, not during it. Our guide to AEC-Q100, Q101 and Q200 grades explains what the qualification does and does not guarantee.

The 6-point substitution check

An MLCC substitute is safe only when it matches the original on six points: dielectric, effective capacitance under DC bias, voltage rating, case size and thickness, qualification grade, and termination style. Same capacitance and same case code is not enough. Run every proposed alternate through these checks and record the result on the change request.

  1. Dielectric and temperature code. X7R is rated to 125 °C, X5R to 85 °C. Moving from X7R to X5R is acceptable only if worst-case ambient plus self-heating stays below 85 °C. Moving from C0G to any Class 2 dielectric is never a like-for-like swap in timing, filter or RF circuits.
  2. Capacitance at your operating voltage. Class 2 MLCCs lose capacitance as DC voltage rises, and a small, high-value part can deliver less than half its label value at its working voltage. Compare both parts on the manufacturers' DC bias curves at your actual rail voltage, not at 0 V.
  3. Voltage rating. A higher rated voltage in the same case usually improves effective capacitance, so an upgrade from 6.3 V to 10 V or 16 V is often the easiest alternate. A lower rating is a design decision, not a purchasing one.
  4. Case size and thickness. The case code fixes length and width, not height. A thicker part can foul a shield can or a pick-and-place nozzle setting. Check the thickness code in the part number, for example the 3.2 mm code in the TDK part shown below.
  5. Qualification grade. An AEC-Q200 part can replace a commercial part; the reverse needs engineering sign-off and, in automotive programmes, customer approval.
  6. Termination and packaging. Flexible or soft terminations protect against board-flex cracking near connectors and board edges. Losing that feature silently raises field failure risk. Also confirm the packaging suffix, because reel and cut tape are different orderable part numbers.

Once an alternate passes, add it to the approved vendor list as a formal second source. Our second-sourcing guide covers how to document it so the next buyer does not repeat the work.

Worked example: covering an automotive X7R line from stock

Consider an EMS provider building an automotive control board that uses the KYOCERA AVX FS031C103K4Z2A, a 10 nF, 100 V, X7R, 0603 FLEXISAFE MLCC rated from -55 °C to +125 °C. KYOCERA AVX states in its KAS series datasheet that FLEXISAFE parts are qualified to AEC-Q200 and combine a flexible termination with a cascade internal design, so points 1, 5 and 6 of the check above rule out most commercial substitutes.

As of September 2026 GlobX lists 130,000 pieces of this part in stock, date code 23+, lifecycle status active, packed in reels of 4,000 and shipping from Germany. The coverage arithmetic is simple:

  • 130,000 pieces divided by 4,000 per reel is 32 full reels plus 2,000 pieces.
  • A board using 6 positions at 2,000 boards per month consumes 12,000 pieces per month.
  • 130,000 divided by 12,000 is about 10.8 months of cover, which is longer than the roughly 40-week worst case reported for high-specification MLCCs.

The practitioner gotcha: the product listing also carries KYOCERA AVX's new global part number, KAS15AR72A103KT, for the same device. If your AVL only holds the legacy FS031 number, a quote against the new number can be rejected by goods-in or flagged as an unapproved substitute, and the line stops even though the part is identical. Add both numbers to the AVL before you place the order.

Two further lines from the GlobX catalogue show how different groups in the table behave. The Yageo CC0402JRNPO9BN330, a 33 pF NP0 0402 part, sits in the low-risk group with 189,000 pieces in stock, date code 22+. The TDK C4532C0G2E473J320KA, a 47 nF, 250 V, C0G part in a 4532 metric (1812) case with a 3.2 mm thickness code, sits in the high-voltage group with 10,000 pieces in stock, date code 19+. That older date code is not a defect for C0G, which does not age like Class 2 dielectrics, but it does warrant a solderability check before use; our shelf life and date code guide gives the acceptance rules.

What to do with your BOM this quarter

The best return on effort in Q4 2026 is a one-day BOM sort that puts every MLCC line into a risk group and assigns an action to the top three groups. A workable order of operations:

  • Export every MLCC line with capacitance, voltage, dielectric, case, grade and annual usage.
  • Tag each line with a risk group from the table above.
  • For severe and high lines, request current lead time and price from two channels and compare against your 12-month demand.
  • Qualify one alternate per severe line using the 6-point check, starting with a higher voltage rating in the same case.
  • Where requalification is too slow, buy cover from verified independent stock with full traceability, and screen it against the risks described in our counterfeit avoidance guide.

New MLCC capacity is reported to arrive from Q4 2026 into 2027, and a passive component production line takes one to two years to build, so plan for high-capacitance and automotive grades to stay tight well into next year. Send GlobX your MLCC lines with target quantities and we will tell you within 24 hours which ones we can cover from European stock and which ones need an alternate.

Frequently Asked Questions

How long will the MLCC shortage last?

Most industry reporting in mid-2026 expects high-capacitance and automotive MLCCs to stay constrained into 2027. New capacity is reported to arrive from Q4 2026, and a passive component line takes one to two years to build and qualify, so relief for standard parts will come well before relief for AI-grade and AEC-Q200 grades.

What is the current lead time for MLCC capacitors?

As of August 2026, distributors reported roughly 14 to 18 weeks for standard MLCCs and 15 to 20 weeks for high-capacitance or high-voltage parts. High-specification grades used in AI servers were reported at up to about 40 weeks. Always confirm a dated quote, because MLCC lead times moved several weeks within a single quarter this year.

Is there a Murata MLCC shortage in 2026?

Murata is not out of stock, but it is capacity-constrained. It confirmed a price increase from 1 April 2026 on four multilayer inductor and ferrite bead lines, and TrendForce reported Murata, Samsung Electro-Mechanics and Taiyo Yuden all running above 80% utilisation. High-end Murata MLCCs face the longest waits, while common values remain orderable.

Can I replace an X7R capacitor with an X5R capacitor?

Only if the circuit never exceeds 85 °C, including ambient temperature plus heat from nearby parts. X7R is rated to 125 °C and X5R to 85 °C, and X5R parts in the same case can also lose more capacitance under DC bias. For automotive, drive or inverter boards, keep X7R or move to X8R.

What does MLCC DC bias derating mean?

DC bias derating is the loss of capacitance a Class 2 MLCC shows when a DC voltage is applied. Small, high-value X5R or X7R parts can lose more than half their label value at working voltage. A practical rule is to pick a rated voltage at least twice the rail voltage and check the manufacturer curve.

Do MLCC capacitors age or lose capacitance in storage?

Class 2 MLCCs such as X7R and X5R lose capacitance over time, typically a small percentage per decade of hours after their last heat exposure, and reflow soldering resets that ageing. Class 1 C0G/NP0 parts do not age measurably. For old date codes, the bigger storage risk is termination solderability rather than capacitance.

Why are capacitor prices increasing in 2026?

Three forces combined in 2026: silver cost increases in electrode and termination materials, AI server boards that use ten to twenty times the MLCC count of a smartphone, and factories already above 80% utilisation. Yageo responded with a 1 July 2026 increase across MLCC, tantalum, polymer, aluminium electrolytic, film capacitors and supercapacitors.
