Is there a pin-compatible replacement for GJM1555C1H1R8WB01D?

Yes, several 0402 package capacitors are pin-compatible, such as the Yageo CC0402BRNPO9BN1R8. However, key electrical parameters like tolerance may differ, so they are not drop-in replacements without verification.

What risks should I check before replacing GJM1555C1H1R8WB01D?

The primary risk is the capacitance tolerance. The target has a tight ±0.05pF tolerance, and many potential substitutes have a looser ±0.1pF tolerance. This can impact the performance of RF filters, oscillators, and other precision timing circuits.

GJM1555C1H1R8WB01D Alternatives, Datasheet & Cross Reference | Murata Manufacturing Co., Ltd.

Finding a substitute for the Murata GJM1555C1H1R8WB01D, a 1.8pF 50V C0G capacitor, requires careful attention to its tight ±0.05pF tolerance. Alternatives exist but often have a looser tolerance, which needs engineering validation.

AI replacement insight

Electrical riskmedium

Tolerance is looser on all found alternates, which is critical for C0G capacitors.

Package risklow

All candidates share the same standard 0402 package.

Sourcing risklow

The target part is active, and alternatives from major manufacturers are widely available.

Can it be replaced directly?

No, a direct, 1-to-1 drop-in replacement for GJM1555C1H1R8WB01D with identical specifications was not identified. All viable candidates require review.

Best replacement path

The closest option is GJM1555C1H1R8BB01D, but it requires accepting a looser tolerance. No direct drop-in replacement with identical specifications was found.

Main risk

The primary risk is the looser capacitance tolerance of available alternatives, which could detune precision RF or timing circuits.

Recommended alternatives

A form-fit-function alternate from the same Murata GJM series with a wider capacitance tolerance.
