Is there a pin-compatible replacement for CC0603KRX7R9BB301?

Yes, many 0603 size MLCCs are pin-compatible. However, a true drop-in replacement requires identical capacitance (300pF), voltage (50V), and dielectric (X7R). Candidates with 330pF capacitance are functionally very close but require review.

What risks should I check before replacing CC0603KRX7R9BB301?

Key risks include capacitance deviation, which can affect timing or filter characteristics, and differences in dielectric properties. Ensure the replacement's voltage and temperature ratings are equal to or better than the original.
