AI replacement insight
Electrical riskmedium
Value and voltage must match use case.
Package risklow
Kept parts are 0603, 2-pin.
Firmware risklow
Passive resistor; no firmware.
Sourcing riskmedium
PDF checks are pending.
Can it be replaced directly?
FRC0603F2491TS is the closest candidate, but PDF and power margin checks are still required.
Best replacement path
Use the same value 2.49kΩ 0603 candidate first; use 2.4kΩ or 2.7kΩ only with circuit recalculation.
Main risk
Resistance changes affect dividers, bias points and feedback networks.
