Is there a pin-compatible replacement for GJM1555C1H2R2WB01D?

Yes, several 0402 package capacitors are pin-compatible in form factor. However, electrical differences like capacitance, tolerance, and Q-factor must be carefully reviewed for your application.

What risks should I check before replacing GJM1555C1H2R2WB01D?

Key risks include: 1) Electrical performance degradation if a general-purpose capacitor replaces this high-Q part in an RF circuit. 2) Circuit detuning due to differences in capacitance value or tolerance.

AI replacement insight

Electrical riskhigh

Mismatch in Q-factor or tolerance can cause circuit failure.

Package risklow

Candidates share the same 0402 package.

Sourcing riskmedium

High-Q capacitors can have limited availability.

Can it be replaced directly?

No exact direct replacement was found. The closest options have relaxed parameters and require engineering validation.

Best replacement path

Use a part from the same GJM series with the closest capacitance and tolerance. GJM1555C1H2R3BB01D is a possible but relaxed option.

Main risk

The main risk is substituting a general-purpose capacitor for this high-Q part, which can degrade performance in RF or timing circuits.

Recommended alternatives

A close parametric alternative with slightly higher capacitance and looser tolerance.
