Is there a pin-compatible replacement for RC0603FR-0791KL?

Several candidates share the same 0603 package and pinout, making them physically compatible. However, none have an identical 91kΩ resistance, so they are not pin-to-pin functional equivalents without review.

What risks should I check before replacing RC0603FR-0791KL?

The main risk is the resistance deviation. Ensure your circuit can tolerate values from 82kΩ to 100kΩ. For the thin-film alternative (RT0603BRD07100KL), also verify compatibility with its different electrical characteristics.
