Is there a pin-compatible replacement for GJM1555C1H2R0WB01D?

Yes, several 0402 capacitors are pin-compatible. GJM1555C1H2R0CB01D is in the same high-Q series but has a looser tolerance. Other parts may differ in series (e.g., general purpose vs. high-Q), which can affect performance in RF circuits.

What risks should I check before replacing GJM1555C1H2R0WB01D?

Key risks include tolerance, Q-factor, and ESR. The target is a high-Q part with tight tolerance (±0.05pF). A substitute with wider tolerance or from a general-purpose series may degrade circuit performance, especially in RF filters or oscillators.

Electrical riskmedium

Tolerance and Q-factor differences can impact RF/timing circuits.

Package risklow

All reviewed candidates are in the standard 0402 package.

Sourcing riskmedium

Some alternatives are NRND (Not Recommended for New Designs).

Can it be replaced directly?

No exact drop-in replacement with identical specifications has been identified. The closest options involve a compromise on tolerance or capacitor series (high-Q vs. general purpose).

Best replacement path

Use another GJM series capacitor like GJM1555C1H2R0CB01D, but verify if the wider tolerance (±0.25pF) is acceptable for your application.

Main risk

The primary risk is performance degradation in high-frequency circuits due to a substitute having a wider tolerance or lower Q-factor.

Recommended alternatives

A pin-compatible High-Q capacitor with the same capacitance and voltage, but a wider tolerance.
