Murata Reported To Be Ending Selected MLCC Part Numbers Across Nine Prefixes, Including GRM

What has been reported

Murata is reported to be discontinuing selected part numbers across nine MLCC prefixes: GRM, GRJ, GRT, GXM, GXT, GCM, GCJ, GCG and ZRA. The nine-prefix list traces to Anue's September 10 report, with the European Passive Components Institute describing the same notice at series level.

The reported timeline runs on Japanese fiscal year ends. Customers give written responses by the end of 2027, last orders are due by 31 March 2028, and last shipments go out by 31 March 2029. Coverage adds that final orders have to meet minimum order and standard packing quantities, and that Murata won't accept cancellations or returns except for quality issues.

The reason Anue quotes from the notice is that Murata is reviewing its MLCC product line to stabilise supply and improve its support structure. Everything else in circulation about freeing capacity for AI servers or exiting low-margin parts is analyst interpretation rather than Murata's words.

What has not been published

The notice covers selected part numbers, not the nine series in full. Those prefixes cover a very large part number range between them, and nobody has published which ones are affected.

We looked for a Murata notice and could not find one. There's nothing on the English or Japanese corporate newsroom and nothing on the ceramic capacitor product pages, and no reference number appears in any coverage we read. The DIGITIMES report that started this is behind a subscription wall, so only its headline and first sentence are publicly readable.

The characterisations going around, that it's mostly larger case sizes or lower-capacitance parts, are inference. They may well be right. They are not something to run a BOM check against.

Don't confuse it with the 2025 notice

There's an earlier Murata end-of-life notice in circulation, carried in distributor change-notification libraries from October 2025, covering large case size MLCCs in GRM, GRT and GCM rated 100V and below. Its dates are last orders 31 March 2027 and last shipments 31 March 2028.

Those dates sit exactly one year before the ones above, which makes the two easy to merge into a single wrong deadline. If someone hands you a Murata EOL date, check which notice it came from.
