Is there a pin-compatible replacement for RC0603JR-0722KL?

Yes, several 0603 package resistors are pin-compatible. For example, RC0603FR-0721KL has the same package and technology but a slightly different resistance (21kΩ) that may be acceptable.

What risks should I check before replacing RC0603JR-0722KL?

When substituting, verify that the new resistance value is within your circuit's tolerance. Also, check for technology differences (Thick vs. Thin Film), as this can affect performance like pulse handling and noise.
