FOJAN FRC0603F5102TS closely matches the 51kΩ ±1% 0603 resistor.
0603WAF5102T5E is a 51kΩ ±1% 0.1W thick film 0603 resistor. Best candidates keep the 0603 size and require rating checks.
Check voltage, power, TCR, and tolerance.
Most kept options are 0603.
Passive resistor; no firmware impact.
Use active catalog parts with checked PDFs.
FRC0603F5102TS is the closest catalog candidate, pending FAE review.
Prefer same 0603, 51kΩ, ±1%, 0.1W thick film parts with confirmed voltage rating.
Tolerance, voltage rating, and footprint changes are the main risks.
