Is there a pin-compatible replacement for GRM155R61H224KE01D?

No direct pin-compatible replacement has been verified from the candidates. Alternatives require careful review of package size and dielectric properties to ensure they fit the board and meet performance needs.

What risks should I check before replacing GRM155R61H224KE01D?

Key risks include package mismatch requiring a PCB redesign, and dielectric differences (e.g., X7R vs. X5R) which affect capacitance stability over temperature and DC bias, potentially impacting circuit performance.

GRM155R61H224KE01D Alternatives, Datasheet & Cross Reference | Murata Manufacturing Co., Ltd.

The Murata GRM155R61H224KE01D is a common 0.22µF 50V ceramic capacitor in a small 0402 package. Finding a direct drop-in replacement requires matching the package, capacitance, voltage, and X5R dielectric.

AI replacement insight

Package riskhigh

Most alternatives are in larger packages (0603, 1206) and are not drop-in replacements.

Electrical riskmedium

Dielectric differences (X7S/X7R vs X5R) affect temperature stability and may require circuit re-evaluation.

Sourcing risklow

The target part is active and widely available; substitutes are for cost or supply chain diversification.

Can it be replaced directly?

No direct drop-in replacement was found. All candidates require significant engineering review due to package or dielectric mismatches.

Best replacement path

Search for 0.22uF, 50V (or higher), 0402 capacitors with X5R or a better (X7R) dielectric.

Main risk

The primary risk is physical incompatibility due to different package sizes, requiring a board layout change.

Recommended alternatives

Functional alternative with same capacitance but larger 0603 package and higher 100V rating.
