Is there a pin-compatible replacement for GCM31CR71H225KA55K?

GCM31CC72A225KE02L shares the same 1206 package and pinout. However, it uses an X7S dielectric, which has different capacitance stability over temperature compared to the target's X7R. This difference must be verified for your circuit.

What risks should I check before replacing GCM31CR71H225KA55K?

Key risks include package size mismatch requiring PCB changes, different dielectric characteristics (e.g., X7S vs. X7R) affecting performance, and ensuring the replacement is also AEC-Q200 qualified for automotive applications.

Finding a substitute for the GCM31CR71H225KA55K, a 2.2µF 50V 1206 AEC-Q200 MLCC, requires careful review of package size, dielectric type, and automotive qualification. Functional and parametric alternatives exist but may require design changes.

AI replacement insight

Electrical riskmedium

Dielectric mismatch (X7S vs X7R) affects capacitance stability.

Package riskhigh

Several alternatives are in a larger 1210 package, requiring a PCB redesign.

Can it be replaced directly?

No direct, drop-in replacement with identical key parameters was found. The closest options have different dielectrics or packages, requiring engineering review.

Best replacement path

For functional equivalence, GCJ32DR72A225KA01L is best if a layout change to 1210 is possible. For form-fit, GCM31CC72A225KE02L is an option if the X7S dielectric is acceptable.

Main risk

The main risks are physical incompatibility due to different package sizes and performance deviation from different dielectric materials or lack of automotive qualification.

Recommended alternatives

Same package and automotive grade, but has a different dielectric (X7S) that requires engineering review.
