LQG15HS82NJ02D
Murata Electronics
Needs validationhigh risk
Same 82nH inductance and 0402 package, with higher current but much lower RF performance (Q, SRF) and wider tolerance.
Best Alternatives to LQW15AN82NG00D
Finding a substitute for the Murata LQW15AN82NG00D 82nH inductor requires careful review. While several alternatives exist, they involve trade-offs in inductance value, RF performance, or package size that must be validated for your application.
AI replacement insight
Electrical riskhigh
Candidates have different inductance, tolerance, or RF performance (Q, SRF). Circuit re-tuning or validation is necessary.
Package riskmedium
Some functional alternates are in a larger 0603 package and are not physically compatible with the 0402 footprint.
Can it be replaced directly?
No direct, drop-in replacement without caveats has been identified. All candidates have significant parametric or physical differences that require engineering review.
Best replacement path
No single best replacement exists. If the 82nH value is critical, LQG15HS82NJ02D is a form-fit option but requires verifying its lower RF performance. If a 68nH value is acceptable, LQW15AN68NG80D offers superior electrical specs.
Main risk
The primary risks are either a mismatch in inductance value or a significant degradation in high-frequency performance (Q-factor and SRF).

Questions & answers
There is no single best alternative. For the same 0402 footprint, LQG15HS82NJ02D matches the 82nH inductance but has lower RF performance. If a 68nH value is acceptable, LQW15AN68NG80D offers better electrical specs. For a new design, LQW18AN82NG00D is an excellent electrical match in a larger 0603 package.
