Is there a pin-compatible replacement for RS-03K1153FT?

Yes, several parts like RS-03K1183FT are pin-compatible in the same 0603 package. However, they are not electrically identical due to different resistance values, so they are not drop-in replacements without engineering validation.

What risks should I check before replacing RS-03K1153FT?

Before replacing, you must check your circuit's tolerance for a different resistance value (e.g., 118kΩ instead of 115kΩ). Also, confirm that the 0.1W power rating is sufficient, as these alternatives do not provide an increased safety margin.
