What risks should I check before replacing FRC0603F3321TS?

Before replacing, verify the resistance value, as many alternatives have slightly different values. Also, check the resistor technology; switching from Thick Film to Thin Film (or vice-versa) can impact performance in sensitive applications like those requiring low noise or specific pulse handling.
