Is there a pin-compatible replacement for GCM1555C1H221JA16D?

Yes, GCM1555C1H221FA16D is a pin-compatible replacement. It shares the same 0402 package, pinout, voltage, capacitance, and C0G dielectric.

What risks should I check before replacing GCM1555C1H221JA16D?

Before replacing, verify two key factors: the dielectric must be C0G (or NP0) for stability, and the replacement must have AEC-Q200 qualification if used in an automotive application.
