Is there a pin-compatible replacement for GRM32ER61A476KE20L?

Yes, parts like GRM32EC81C476KE15L are pin-compatible in the same 1210 package. However, they have a different X6S dielectric, which has different temperature characteristics than the original X5R part and must be evaluated.

What risks should I check before replacing GRM32ER61A476KE20L?

Key risks include package size differences (e.g., 1206 vs. 1210) and changes in dielectric material (e.g., X5R vs. X6S), which affects capacitance stability over temperature. Always verify the substitute's datasheet.

AI replacement insight

Electrical riskmedium

Dielectric change from X5R to X6S affects capacitance stability.

Package riskmedium

Some alternatives are in a smaller 1206 package, requiring layout verification.

Sourcing risklow

Multiple alternatives from the same manufacturer are available.

Can it be replaced directly?

No direct drop-in replacement without caveats is identified. All candidates require review of either package size or dielectric characteristics.

Best replacement path

For a functional match, use GRT31CR61A476KE13L and verify the 1206 package fits 1210 pads. For the same package, use GRM32EC81C476KE15L and validate X6S dielectric performance.

Main risk

The primary risks are physical incompatibility due to package size changes or electrical performance deviation from a different dielectric material (X6S vs. X5R).
