Is there a pin-compatible replacement for GRM188R61E475KE15D?

Yes, the Murata GRT188R6YA475KE13D is a pin-compatible replacement. It shares the same 0603 package, 4.7µF capacitance, and X5R dielectric, with an improved voltage rating.

What risks should I check before replacing GRM188R61E475KE15D?

When substituting, verify the package size (0603), voltage rating (≥25V), and dielectric type (X5R). Using a different dielectric like X6S will alter the capacitor's stability over temperature and requires engineering validation.

AI replacement insight

Electrical risklow

Low if matching dielectric and voltage rating.

Package riskhigh

High if selecting a non-0603 part, as it will not fit the PCB.

Can it be replaced directly?

Yes, the Murata GRT188R6YA475KE13D is a direct, pin-compatible upgrade for the GRM188R61E475KE15D.

Best replacement path

Select an alternative with the same 0603 package, X5R dielectric, and a voltage rating of 25V or higher, such as the automotive-grade GRT188R6YA475KE13D.

Main risk

The main risk is selecting a part with a different package size (e.g., 0805) or a different dielectric (e.g., X6S), which would require a PCB redesign or introduce performance variations.

Recommended alternatives

A pin-compatible upgrade with a higher voltage rating (35V) and automotive-grade qualification.
