Is there a pin-compatible replacement for GJM1555C1HR20WB01D?

Yes, parts like GJM1555C1HR30WB01D are pin-compatible (0402 package), but they are not electrically identical due to different capacitance values.

What risks should I check before replacing GJM1555C1HR20WB01D?

The primary risk is the change in capacitance. You must verify if your circuit, especially if it's for timing or RF, can function correctly with a different capacitance value.
