LQG15HS3N9B02D
Murata Electronics
Needs validationmedium risk
Form-fit compatible with better DCR, but has lower inductance (3.9nH) than the target's 4.3nH.
Best Alternatives to LQG15HS4N3B02D
Finding a substitute for the Murata LQG15HS4N3B02D 4.3nH inductor requires matching its 0402 package, 750mA current rating, and low DCR. Alternatives may have parametric differences.
AI replacement insight
Electrical riskhigh
Inductance and current ratings vary across candidates.
Package risklow
All reviewed candidates use a compatible 0402 package.
Sourcing riskmedium
Alternatives are from different vendors or have different stock levels.
Can it be replaced directly?
No direct, 1-to-1 replacement has been identified. All candidates require a review of key electrical parameters, especially inductance.
Best replacement path
Parametric alternatives from the same manufacturer family, like the Murata LQG15HS series, are the first choice but require inductance verification.
Main risk
The primary risk is inductance mismatch, which can detune RF circuits or alter filter characteristics. Current rating must also be met.
