Is there a pin-compatible replacement for RT0603BRE07120KL?

Several parts share the 0603 package, but no exact parametric match was found. Candidates with different resistance values exist, but require careful review to ensure they meet your application's precision requirements.

What risks should I check before replacing RT0603BRE07120KL?

The main risk is parametric mismatch. The target is a 0.1% precision resistor. Ensure any substitute has the same or better tolerance, TCR, and technology (Thin Film). Also, verify that any deviation in resistance value is acceptable.
