Is there a pin-compatible replacement for CC0805KRX7R9BB333?

No. The kept candidates are 0603, while the target is 0805, so pin-compatible replacement is not confirmed.

What risks should I check before replacing CC0805KRX7R9BB333?

Check capacitance, voltage margin, dielectric, tolerance, temperature range, termination, and PCB footprint.

CC0805KRX7R9BB333 is a 33nF 50V X7R 0805 MLCC. The candidates found need caution: exact 0805 value matches were not present here.

Rejected 0805 parts change capacitance.

Kept parts are 0603, not 0805.

Passive MLCC; no firmware impact.

Kept candidates are active and indexed.

No confirmed pin-compatible replacement is available in these candidates.

Prefer a 33nF 50V X7R ±10% MLCC in 0805; 0603 options require footprint review.

Package mismatch or capacitance change can alter circuit behavior.

33nF 50V X7R ±5% option in 0603; not a direct 0805 replacement.
