Is there a pin-compatible replacement for CC0805KRX7R9BB681?

Yes, parts like CC0805JRNPO0BN681 and CC0805JRNPO9BN681 share the same 0805 package and 2-pin layout, making them physically pin-compatible. However, you must review the electrical differences, such as the improved dielectric.

What risks should I check before replacing CC0805KRX7R9BB681?

The main point to verify is the change in dielectric from X7R to C0G/NP0. While C0G is more stable and generally an upgrade, ensure this change is acceptable for your circuit's performance and cost targets.
