AI replacement insight
Electrical risklow
Resistance differs by 6%; tolerance is improved.
Package risklow
Package is identical.
Can it be replaced directly?
Direct replacement for AC0402JR-0747KL should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
The most straightforward path is AC0402FR-0749K9L, which only requires verifying the circuit's tolerance to a +6% resistance shift.
Main risk
The primary risk is the slight mismatch in resistance values, which could affect circuit performance if the design is sensitive to this parameter.
