AI replacement insight

Electrical riskmedium

Dielectric mismatch (X5R vs X6S) affects temperature stability.

Package risklow

Many alternatives share the same 0402 package.

Can it be replaced directly?

Yes, GRM155C81C225KE11D is a direct replacement with tighter tolerance (±10% vs ±20%). Other upgrades like GRT155C81C225KE13D (automotive grade) are also available.

Best replacement path

Use a pin-compatible Murata MLCC from the GRM or GRT series with identical or better specifications, such as GRM155C81C225KE11D for tighter tolerance.

Main risk

The primary risk is selecting a capacitor with a different dielectric, such as X5R instead of X6S, which can lead to reduced performance at higher operating temperatures.

Recommended alternatives

Pin-to-pin compatible replacement with tighter ±10% tolerance.
