AI replacement insight
Electrical riskmedium
Power margin and value tolerance need application review.
Package risklow
Kept candidates are listed as 0805.
Firmware risklow
Passive resistor, no firmware interface.
Sourcing riskmedium
Availability was not provided.
Can it be replaced directly?
FRC0805F4990TS is the closest catalog match, but it still needs datasheet and derating review.
Best replacement path
Use the same 499Ω, 0805, 0.125W candidate first; consider 500Ω only if the circuit tolerance allows it.
Main risk
Nominal resistance changes in 500Ω, 510Ω, or 470Ω parts can alter circuit behavior.
