Best Alternatives to GRM1555C1H221JA01D
GRM1555C1H221JA01D is a 220pF, 50V, C0G MLCC in an 0402 package from Murata, now Not Recommended for New Designs (NRND). Engineers can find active, pin-compatible replacements.
AI replacement insight
Electrical riskhigh
High risk if substituting with a non-C0G dielectric.
Package risklow
Low risk if replacement is also 0402 package.
Sourcing risklow
Target is NRND; active replacements improve availability.
Can it be replaced directly?
Direct replacement for GRM1555C1H221JA01D should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
The best replacement is an active 0402 MLCC with 220pF, 50V, and a C0G/NP0 dielectric, like Yageo's CC0402JRNPO9BN221.
Main risk
The main risk is substituting with a different dielectric (e.g., X7R instead of C0G), which affects circuit stability and performance.
