Is there a pin-compatible replacement for RC-02K9101FT?

Yes, FRC0402F9101TS from FOJAN is a pin-compatible replacement. It has the same 9.1kΩ resistance, ±1% tolerance, 1/16W power rating, and 0402 package.

What risks should I check before replacing RC-02K9101FT?

Before replacing, check two main risks. First, if using a 'parametric_relaxed' part, verify your circuit tolerates the different resistance value. Second, for all parts, confirm the identical power (1/16W) and voltage (50V) ratings provide sufficient safety margin in your design.
