What risks should I check before replacing GJM1555C1H8R2BB01D?

The primary risk is a mismatch in the Q-factor (Quality Factor), as the target is a High-Q part. A lower Q-factor in a substitute can increase signal loss in RF filters or tuning circuits. Always compare the Q-factor or ESR curves from the datasheets at your frequency of operation.

CC0402BRNPO9BN8R2

Main risk

The main risk is functional, stemming from replacing a High-Q capacitor with a general-purpose one, which may impact performance in high-frequency circuits.

Recommended alternatives

Yageo MLCC with identical package and electricals. Review Q-factor as it is a general-purpose, not High-Q, part.
