Is there a pin-compatible replacement for GJM1555C1H180FB01D?

Several parts are pin-compatible as they share the 0402 package, such as Murata's GCM1555C1H180JA16D and Yageo's CC0402GRNPO9BN180. However, they are not functionally identical due to differences in tolerance and application grade.

What risks should I check before replacing GJM1555C1H180FB01D?

The main risks are electrical. The target has a tight ±1% tolerance and is for high-Q RF circuits. Using a substitute with a wider tolerance (e.g., ±5%) or a general-purpose grade can affect circuit timing, filter characteristics, and overall performance.

Finding a substitute for the GJM1555C1H180FB01D, a precision 18pF 50V 1% C0G capacitor, requires careful review. While several parts match the package and capacitance, they often have wider tolerance and are not designed for high-Q RF applications.

AI replacement insight

Electrical riskhigh

Wider tolerance and different series (general purpose vs. high-Q) can alter circuit performance.

Package risklow

All reviewed candidates use the same 0402 package, ensuring physical compatibility.

Can it be replaced directly?

No direct drop-in replacement has been identified. All candidates have weaker tolerance or are not specified for high-Q RF use, requiring engineering validation.

Best replacement path

Find a C0G/NP0 capacitor with 18pF, 50V, and ±1% tolerance in a 0402 package, preferably from a high-Q RF series.

Main risk

The primary risk is performance degradation in RF or timing circuits due to wider capacitance tolerance and potentially lower Q-factor.

Recommended alternatives

A 18pF 50V C0G capacitor in the same 0402 package, but with a wider ±5% tolerance.
