Is there a pin-compatible replacement for GJM1555C1H5R0BB01D?

Yes, GJM1555C1H5R1BB01D is a pin-compatible replacement. It shares the same 0402 package, pinout, and key electrical ratings, making it a strong candidate for direct substitution.

What risks should I check before replacing GJM1555C1H5R0BB01D?

Key risks include using a general-purpose capacitor instead of a high-Q one, which can degrade performance in RF circuits. Also, verify that any small difference in capacitance (e.g., 5.1pF vs 5.0pF) and tolerance is acceptable for your application.

Electrical riskhigh

Using a non-High-Q part can cause circuit malfunction in RF applications.

Package risklow

All candidates use the standard 0402 package.

Sourcing riskmedium

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

Can it be replaced directly?

GJM1555C1H5R1BB01D is a near-direct replacement, matching the critical high-Q characteristic and package.

Best replacement path

Use another Murata GJM series capacitor like GJM1555C1H5R1BB01D to maintain high-Q performance.

Main risk

The main risk is substituting with a general-purpose capacitor (e.g., Murata GRM or Yageo CC series), which will have lower Q-factor and higher losses at high frequencies.

Recommended alternatives

Excellent alternative from the same High-Q series with nearly identical parameters.
