AI replacement insight
Electrical riskmedium
Resistance values differ by 2.4% to 7.4%. One candidate has a different technology (Thin Film).
Package risklow
All candidates use the same 0402 package, ensuring physical compatibility.
Can it be replaced directly?
No direct drop-in replacement was found in this analysis. All suggested alternatives require engineering review due to differences in resistance value or resistor technology.
Best replacement path
The best path is to find a 7.87kΩ, 1%, 0.0625W, 0402 thick film resistor. The closest alternatives found are FRC0402F8061TS and ERJ2RKF7681X, which have a ~2.4% resistance deviation.
Main risk
The primary risk is the deviation in resistance value from the 7.87kΩ target, which can affect circuit performance. One candidate also uses a different resistor technology.
