Is there a pin-compatible replacement for GRM21BR60J476ME15L?

No, a direct pin-compatible (0805 package) replacement with the same key parameters was not found in this review. All suitable alternatives are in different packages, such as 1206 or 0603.

What risks should I check before replacing GRM21BR60J476ME15L?

The main risk is the package mismatch. You must verify your PCB layout can accommodate a different size (1206 or 0603). Also, confirm the DC bias and temperature characteristics of the X5R dielectric are acceptable for your circuit.

Finding a substitute for the Murata GRM21BR60J476ME15L, a 47µF 6.3V 0805 MLCC, requires careful consideration of package size. While functional alternatives exist, they may require PCB layout modifications.

AI replacement insight

Package riskhigh

No alternatives in the same 0805 package were found; layout change is required.

Electrical risklow

Functional alternatives have matching or better electrical specs (voltage, capacitance).

Can it be replaced directly?

No direct pin-compatible replacements were identified. All viable alternatives require a change in the PCB footprint.

Best replacement path

Use a functional alternative like GRM31CR61A476ME15L (1206) or GRM188R60J476ME15D (0603) and adapt the PCB layout.

Main risk

The primary risk is the package mismatch, which makes these parts not drop-in compatible and requires a board redesign.

Recommended alternatives

Functionally identical but in a smaller 0603 package, requiring layout changes.
