Is there a pin-compatible replacement for GJM1555C1H2R7BB01D?

Yes, GJM1555C1H2R7WB01D is a pin-compatible replacement. It shares the same 0402 package, pinout, voltage, and capacitance, making it suitable for direct substitution.

What risks should I check before replacing GJM1555C1H2R7BB01D?

The main risk is substituting a general-purpose capacitor (like Murata's GRM series) for this High-Q (GJM series) part. This can degrade performance in RF or high-frequency applications. Always verify the capacitor series matches the application's needs.
