Is there a pin-compatible replacement for GJM1555C1H5R6WB01D?

Yes, parts like GRM1555C1H5R6BA01D and CC0402CRNPO9BN5R6 are pin-compatible in the 0402 package. However, they are not functionally identical and require careful review of their electrical characteristics, especially tolerance and Q-factor.

What risks should I check before replacing GJM1555C1H5R6WB01D?

Key risks include: 1) Weaker capacitance tolerance affecting circuit precision. 2) Lower Q-factor from using a general-purpose part, which can impact performance in RF/high-frequency circuits. 3) Lifecycle status, as some alternatives may be Not Recommended for New Designs (NRND).

GJM1555C1H5R6WB01D Alternatives, Datasheet & Cross Reference | Murata Manufacturing Co., Ltd.

Finding a substitute for the Murata GJM1555C1H5R6WB01D, a 5.6pF 50V High-Q 0402 capacitor, requires careful matching of its tight tolerance (±0.05pF) and High-Q characteristics for RF applications. Alternatives may have looser tolerances or be general-purpose types.

AI replacement insight

Electrical riskhigh

Mismatch in tolerance and Q-factor can cause circuit malfunction.

Package risklow

Standard 0402 package is widely available.

Sourcing riskmedium

High-Q capacitors are more specialized than general-purpose ones.

Can it be replaced directly?

No direct drop-in replacement has been identified. The closest options are functional downgrades, requiring engineering review of tolerance and Q-factor for the specific application.

Best replacement path

Search for other Murata GJM series or equivalent High-Q capacitors from other vendors with 5.6pF capacitance and tolerance of ±0.05pF or ±0.1pF.

Main risk

The primary risk is substituting a general-purpose capacitor for the target's High-Q type, which can degrade performance in RF or high-frequency circuits.

Recommended alternatives

A form-fit compatible capacitor, but is a general purpose type with weaker tolerance and is NRND.
