Is there a pin-compatible replacement for CC0603KRNPO9BN102?

Yes, several pin-compatible replacements exist in the same 0603 package. AC0603JRNPO9BN102 is a direct upgrade. Any 1nF, 50V (or higher) capacitor with an NP0/C0G dielectric in a 0603 package is a strong candidate.

What risks should I check before replacing CC0603KRNPO9BN102?

The main risk is using a substitute with a different dielectric type, such as X7R or X8R. The target's NP0/C0G dielectric is very stable. Using a less stable dielectric can negatively affect performance in timing, filtering, or RF circuits. Always verify the substitute has an NP0 or C0G dielectric.
