AI replacement insight
Electrical risklow
Values match; check derating.
Package risklow
All kept parts are 0603.
Firmware risklow
Passive resistor only.
Sourcing riskmedium
Some evidence is distributor-based.
Can it be replaced directly?
RC0603JR-075K1L and FRC0603J512 TS are closest by value, package, tolerance and power.
Best replacement path
Prefer same 0603, 5.1 kΩ, equal or tighter tolerance, 0.1 W or higher, with confirmed voltage and pulse limits.
Main risk
Same-power parts need application derating and pulse-load verification.
