Is there a pin-compatible replacement for GRT21BR61H475KE13L?

Yes, parts like Murata's GRM21BZ71H475KE15K share the 0805 package but are not AEC-Q200 qualified and use a different dielectric, making them functionally different and requiring engineering review.

What risks should I check before replacing GRT21BR61H475KE13L?

Key risks include using a non-AEC-Q200 part in an automotive application, and dielectric differences (e.g., X7R, X7S vs. X5R) which affect capacitance stability over temperature and DC bias.

GRT21BR61H475KE13L Alternatives, Datasheet & Cross Reference | Murata Manufacturing Co., Ltd.

The Murata GRT21BR61H475KE13L is a 4.7µF, 50V, 0805 AEC-Q200 qualified MLCC. Finding a direct replacement requires matching its automotive grade and X5R dielectric performance.

AI replacement insight

Electrical riskmedium

Dielectric mismatch (X7R/X7S vs X5R) affects capacitance stability.

Sourcing riskhigh

Substituting a non-AEC-Q200 part for an automotive one creates a high reliability risk.

Can it be replaced directly?

No direct, drop-in replacement has been verified. Alternatives exist with the same package but differ in automotive qualification and dielectric type, posing a high risk.

Best replacement path

Search for AEC-Q200 qualified 4.7µF 50V 0805 MLCCs, prioritizing X5R or superior dielectrics like X7R if application temperature range allows.

Main risk

The primary risk is substituting a non-automotive grade capacitor into an AEC-Q200 required design, which can lead to premature failure.

Recommended alternatives

Alternative in the same 0805 package but with X7R dielectric and for general-purpose use.
