What risks should I check before replacing FRC0805J243 TS?

Before replacing, check your circuit's sensitivity to resistance. While some alternatives are very close (e.g., 23.2kΩ, 24.9kΩ), they are not exact. Also verify the temperature coefficient (TCR) if operating in environments with wide temperature swings.
