Is there a pin-compatible replacement for GCM1555C1H181FA16D?

While several candidates share the 0402 package, none are electrically equivalent. A pin-compatible replacement must be validated by an engineer for electrical differences.

What risks should I check before replacing GCM1555C1H181FA16D?

Key risks include: 1) Capacitance difference affecting circuit timing or filtering. 2) Wider tolerance impacting precision. 3) Using a non-automotive part (GRM series) in an automotive application.

GCM1555C1H181FA16D Alternatives, Datasheet & Cross Reference | Murata Manufacturing Co., Ltd.

Finding a substitute for the Murata GCM1555C1H181FA16D, a 180pF 50V 1% automotive MLCC, requires careful review of capacitance, tolerance, and qualification grade. While form-fit alternatives exist, direct electrical matches are scarce.

AI replacement insight

Electrical riskhigh

All candidates have different capacitance or tolerance values.

Package risklow

All candidates share the same 0402 package.

Sourcing riskmedium

Several reviewed candidates are NRND, indicating potential obsolescence issues in the family.

Can it be replaced directly?

No direct, drop-in replacement was found. All candidates require an engineering review due to differences in capacitance, tolerance, or qualification.

Best replacement path

Search for automotive-grade (AEC-Q200) 0402 MLCCs with 180pF capacitance and ±1% tolerance from other manufacturers.

Main risk

The primary risk is substituting a general-purpose capacitor for an automotive-grade one, which can lead to reliability issues in harsh environments.

Recommended alternatives

An automotive-grade alternative with the same package, but lower capacitance and wider tolerance.
