Is there a pin-compatible replacement for GJM1555C1H7R5BB01D?

Yes, parts like GRM1555C1H7R5BA01D are pin-compatible in the 0402 package, but they are general purpose and not high-Q, posing a high risk in RF applications. Always verify performance.

What risks should I check before replacing GJM1555C1H7R5BB01D?

The main risk is using a general purpose capacitor instead of a high-Q type, which can degrade performance in RF circuits. Also check for tolerance, voltage rating, and lifecycle status.

GJM1555C1H7R5BB01D Alternatives, Datasheet & Cross Reference | Murata Manufacturing Co., Ltd.

GJM1555C1H7R5BB01D is a 7.5pF 50V high-Q ceramic capacitor in a 0402 package, designed for high-frequency RF applications. Finding a direct replacement requires matching its high-Q performance.

AI replacement insight

Electrical riskhigh

Using a general purpose cap instead of high-Q can degrade RF circuit performance (e.g., lower filter selectivity, phase noise).

Package risklow

Standard 0402 package is widely available and compatible.

Can it be replaced directly?

No direct, risk-free replacement was found. All candidates with matching capacitance are general purpose, which is a functional downgrade from the target's high-Q series.

Best replacement path

Search for another Murata GJM series or a competitor's high-Q RF capacitor with identical key parameters.

Main risk

Functional mismatch: substituting a general-purpose capacitor for a high-Q RF capacitor.

Recommended alternatives

A 7.5pF 50V 0402 capacitor with same tolerance, but is a general purpose type and NRND.
