Is there a pin-compatible replacement for GRM1555C1E221JA01D?

Yes, GCM1555C1H221JA16D, GCM1555C1H221FA16D, and CC0402GRNPO9BN221 are all pin-compatible replacements in the same 0402 package with superior or identical electrical characteristics.

What risks should I check before replacing GRM1555C1E221JA01D?

The primary risk is selecting a replacement with the wrong dielectric. You must use a C0G (NP0) capacitor. Using an X7R or other Class 2 dielectric will compromise circuit performance and stability.

GRM1555C1E221JA01D is a 220pF 25V 0402 C0G capacitor that is not recommended for new designs (NRND). Fortunately, several active, pin-compatible upgrades are available with higher voltage ratings and tighter tolerances.

AI replacement insight

Electrical riskhigh

Using a non-C0G dielectric (e.g., X7R) will likely cause circuit failure in timing or filtering applications.

Package risklow

Many alternatives exist in the same 0402 package, ensuring physical compatibility.

Sourcing risklow

Multiple vendors offer suitable C0G replacements, mitigating sourcing challenges for the NRND target.

Can it be replaced directly?

Yes, several direct, pin-compatible replacements are available for GRM1555C1E221JA01D, including upgraded parts from Murata's GCM series and alternatives from Yageo.

Best replacement path

The best replacement path is to an automotive-grade Murata GCM series part like GCM1555C1H221FA16D, which offers superior tolerance and voltage rating.

Main risk

The main risk is substituting with a capacitor that has a different dielectric, such as X7R, which lacks the temperature and voltage stability of the original C0G part.

Recommended alternatives

A high-precision upgrade with tighter tolerance (±1%), higher voltage (50V), and automotive grade.
