AI replacement insight
Electrical risklow
Most candidates have small resistance deviations. One has a technology change.
Package risklow
All candidates share the same 0603 package.
Can it be replaced directly?
No exact drop-in replacement was found. The closest options have minor resistance differences or use a different resistor technology, requiring engineering review.
Best replacement path
For precision, use RT0603BRD0780K6L but check technology. For general use, RC0603FR-0776K8L or FRC0603F7872TS are good options after verifying resistance tolerance.
Main risk
The main risk is substituting with a part outside the circuit's required resistance tolerance. A secondary risk involves the technology change from Thick to Thin Film.
