Is there a pin-compatible replacement for RL10FTNR100?

Yes, several 0805 package resistors are pin-compatible, such as Yageo PE0805FRF470R1L. However, you must verify electrical parameters like power rating, technology (Alloy vs. Metal/Thick Film), and TCR to ensure it functions correctly in your circuit.

What risks should I check before replacing RL10FTNR100?

The main risks are changes in performance due to different resistor technology (Alloy vs. Thick/Metal Film) and a worse Temperature Coefficient (TCR). Also, ensure the replacement has an equal or higher power rating, leaving sufficient design margin.
