Is there a pin-compatible replacement for GJM1555C1HR70WB01D?

Yes, several parts like GJM1555C1HR60WB01D are pin-compatible in the same 0402 package. However, they are not electrically identical, as their capacitance values differ. Engineering validation is required.

What risks should I check before replacing GJM1555C1HR70WB01D?

The main risk is the change in capacitance, which can affect the performance of timing-sensitive or RF circuits. You must verify that your design can function correctly with a capacitance value that is higher or lower than the original 0.7pF.

GJM1555C1HR70WB01D Alternatives, Datasheet & Cross Reference | Murata Manufacturing Co., Ltd.

Finding a substitute for the Murata GJM1555C1HR70WB01D, a 0.7pF 50V C0G capacitor, involves navigating parametric differences. While no direct drop-in replacement exists, several form-fit compatible alternatives from the same series are available but require careful review of their capacitance values.

AI replacement insight

Electrical riskmedium

Capacitance value is different in all candidates. Tolerance may also be wider.

Package risklow

All candidates share the same 0402 package, ensuring physical compatibility.

Can it be replaced directly?

No direct, 1-to-1 replacement was found. All identified alternatives have different capacitance values and require engineering review before substitution.

Best replacement path

Use a part from the same Murata GJM series with the closest capacitance, like GJM1555C1HR60WB01D (0.6pF) or GJM1555C1HR90WB01D (0.9pF), after performing circuit analysis to confirm tolerance for the capacitance shift.

Main risk

The primary risk is capacitance mismatch, which can detune RF filters, alter timing constants, or affect impedance matching in high-frequency circuits.

Recommended alternatives

A form-fit alternate with slightly lower capacitance that requires engineering review.
