AI replacement insight
Electrical risklow
Resistance values of the best candidates are within 3% of the target.
Package risklow
All suggested alternatives use the same 0402 package.
Can it be replaced directly?
No exact drop-in replacement is listed, but several parts like 0402WGF1781TCE are form, fit, and functionally very similar. A small resistance difference of ~2-3% must be evaluated for the specific application.
Best replacement path
For the closest match, consider other 1% 0402 resistors from the UNI-ROYAL WGF series like 0402WGF1781TCE (1.78kΩ) or 0402WGF1691TCE (1.69kΩ), which offer very similar performance.
Main risk
The primary risk is the slight deviation in resistance value, which could affect circuit timing, gain, or filtering characteristics. All candidates have the same or better power and voltage ratings.
