Is there a pin-compatible replacement for RC0402JR-0750RL?

Yes, several pin-compatible replacements exist. Look for any 0402 chip resistor with 50 Ohm resistance, a power rating of at least 0.0625W (1/16W), and a tolerance of ±5% or better.

What risks should I check before replacing RC0402JR-0750RL?

The primary risk is selecting a part with a different package size (e.g., 0603 instead of 0402), which will not fit the PCB. Also, if considering a thin film resistor, verify its performance characteristics are suitable for your application.
