Is there a pin-compatible replacement for GRM155R61C105MA12D?

Yes, both GRM155R61E105KE11D and GRT155R61C105KE01D are pin-compatible replacements in the same 0402 package with improved electrical specifications.

What risks should I check before replacing GRM155R61C105MA12D?

Check for package size mismatch, which requires a new PCB layout. Also, if the dielectric code differs (e.g., X6S vs. X5R), you must verify the capacitor's performance over your application's temperature and DC bias range.

AI replacement insight

Electrical risklow

Low for upgrades with matched dielectric. Medium if dielectric differs (e.g., X6S).

Package riskhigh

High for any part not in an 0402 package, as it requires a PCB redesign.

Can it be replaced directly?

Yes, GRM155R61E105KE11D is a direct upgrade with improved voltage and tolerance, and GRT155R61C105KE01D is an automotive-grade upgrade.

Best replacement path

Upgrade to GRM155R61E105KE11D for higher voltage (25V) and tighter tolerance (±10%) in the same 0402 package.

Main risk

The main risk is selecting an alternative with a different package size or dielectric material without proper engineering review.

Recommended alternatives

A direct upgrade with higher voltage (25V) and tighter tolerance (±10%) in the same 0402 package.
