Is there a pin-compatible replacement for GJM1555C1HR90WB01D?

Yes, several alternatives like GJM1555C1HR70WB01D share the same 0402 package and are pin-compatible from a physical standpoint. However, they are not electrically equivalent due to different capacitance values.

What risks should I check before replacing GJM1555C1HR90WB01D?

The primary risk is the capacitance mismatch. Since this is a high-Q capacitor, changing the capacitance will likely detune RF filters, oscillators, or matching networks, leading to circuit failure. Always verify performance in your application.
