What risks should I check before replacing FRC0603F1742TS?

The primary risk is the change in resistance. Verify your circuit can tolerate values like 16.9kΩ or 18.0kΩ. Also check power rating, temperature coefficient (TCR), and voltage rating to ensure they meet or exceed the original's specifications.
