Is there a pin-compatible replacement for RS-03K3300FT?

Yes, both RC0603FR-07330RL from Yageo and FRC0603F3300TS from FOJAN are pin-compatible replacements. They share the same 0603 package, pinout, and key electrical characteristics.

What risks should I check before replacing RS-03K3300FT?

The main risk is using a part with relaxed parameters. Several alternatives have a ±5% tolerance instead of ±1%. This can affect the accuracy of your circuit. Also, check the Temperature Coefficient (TCR) to ensure stability.
