Is there a pin-compatible replacement for GRT31CR61A476KE13L?

No, a direct pin-compatible replacement was not identified. All reviewed candidates have different package sizes (e.g., 1210 or 0805) than the target's 1206 package, which means they will not drop into the same PCB footprint without verification.

What risks should I check before replacing GRT31CR61A476KE13L?

Before replacing, you must verify: 1) Package compatibility, as alternatives are larger (1210) or smaller (0805). 2) Application qualification, as many lack the target's AEC-Q200 rating. 3) Electrical parameters like dielectric type (X5R vs. X6S) and tolerance, which affect performance.

Finding a substitute for the GRT31CR61A476KE13L, an automotive-grade 47µF 1206 MLCC, is challenging. Potential alternatives often differ in package size, dielectric material, or automotive qualification, requiring careful engineering review before use.

AI replacement insight

Package riskhigh

All candidates have different packages (1210, 0805) requiring PCB layout verification.

Electrical riskhigh

Some candidates have different dielectrics (X6S) or wider tolerance (20%), affecting performance.

Sourcing riskhigh

Several candidates are not AEC-Q200 qualified, making them unsuitable for the target's automotive application.

Can it be replaced directly?

No, a direct drop-in replacement for GRT31CR61A476KE13L was not found. All potential alternatives have different packages, dielectrics, or qualifications that require engineering review.

Best replacement path

The best path is to find another 47µF, 10V (or higher), X5R, AEC-Q200 capacitor in a 1206 package. If unavailable, GRT32EC81C476KE13L is the closest functional match but requires board layout and thermal performance verification.

Main risk

The main risks are physical incompatibility due to different package sizes and failure to meet application requirements due to missing AEC-Q200 qualification.

Recommended alternatives

AEC-Q200 qualified alternate with higher voltage but different package and dielectric; requires engineering review.
