Is there a pin-compatible replacement for RC2512FK-7W300RL?

Yes, several alternatives like HP122WJ0301T4E and CRH2512F330RE04Z share the 2512 package for pin-compatible mounting. However, their electrical parameters differ, so they are not direct functional replacements without engineering review.

What risks should I check before replacing RC2512FK-7W300RL?

The main risks are electrical. Using a part with wider tolerance (e.g., ±5% vs ±1%) can reduce precision in sensitive circuits. Using a part with a different resistance value (e.g., 330Ω vs 300Ω) will alter the circuit's behavior. Always verify the impact on your design.
