Is there a pin-compatible replacement for RS-03K241JT?

Yes, there are several pin-compatible replacements. RS-03K2400FT is from the same manufacturer series but with tighter tolerance. FRC0603F2400TS is a strong cross-vendor alternative with similar upgraded specs.

What risks should I check before replacing RS-03K241JT?

Before replacing, check three main things: 1) For parametric relaxed options, ensure your circuit can tolerate a worse TCR. 2) For upgrade paths, verify the different technology (e.g., thin film) is suitable for your application's pulse/ESD environment. 3) Confirm your design's power dissipation is well within the 0.1W rating.
