AI replacement insight
Electrical riskmedium
Resistance values differ from the target, requiring circuit analysis.
Package risklow
All suggested alternatives share the same 0201 package.
Can it be replaced directly?
No direct drop-in replacement with the exact 43kΩ resistance was found. Several parametric alternatives in the same 0201 package are available but require review.
Best replacement path
Use a parametric alternative with the closest resistance value, like 0201WMF4122TEE (41.2kΩ), after verifying circuit tolerance.
Main risk
The primary risk is the deviation in resistance, which could affect circuit performance.
