Is there a pin-compatible replacement for FRC0402F3833TS?

Yes, several resistors in the same 0402 package are pin-compatible. However, none have the exact 383kΩ resistance. They are considered parametric alternatives, meaning you must verify if your circuit can tolerate a slightly different resistance value.

What risks should I check before replacing FRC0402F3833TS?

The main risk is the change in resistance. Before replacing, verify its impact on your circuit's performance, especially for timing, biasing, or feedback loops. Also confirm that the temperature coefficient (TCR) and voltage ratings of the replacement are acceptable.
