Is there a pin-compatible replacement for GRM155R61E105KE11D?

Yes, several manufacturers offer 1µF, 25V, 0402 capacitors that are physically pin-compatible. However, you must verify the dielectric type (e.g., X5R, X6S, X7R) and its temperature characteristics to ensure it meets your design's performance needs.

What risks should I check before replacing GRM155R61E105KE11D?

Key risks include package size mismatch, which prevents physical replacement, and dielectric differences (e.g., X5R vs. X7R), which affect capacitance stability over temperature and DC bias. Always check the voltage rating is equal or higher.

AI replacement insight

Electrical riskmedium

Dielectric mismatch requires review of temperature characteristics.

Package riskhigh

Many functional alternatives are in different, larger packages.

Firmware risklow

Not applicable for a passive component.

Can it be replaced directly?

No exact drop-in replacement is guaranteed without review. Murata's GRT155C81E105KE13D is a strong candidate with the same package but a different dielectric (X6S) that requires engineering review.

Best replacement path

Prioritize candidates with the same 0402 package and X5R dielectric. If unavailable, consider X6S or X7R dielectrics, but review the impact on capacitance stability.

Main risk

The main risk is substituting with a different dielectric (e.g., X7R, X6S), which can alter performance due to different capacitance stability over temperature and DC bias.

Recommended alternatives

A 1uF, 25V capacitor in the same 0402 package, but with an X6S dielectric that requires engineering review.

Questions & answers

The best alternative depends on application constraints. For a near drop-in replacement, look for a 1µF, 25V (or higher), 0402 package capacitor like Murata's GRT155C81E105KE13D, but verify the dielectric (X6S vs. X5R) is acceptable for your circuit's temperature stability requirements.
