AI replacement insight

Electrical riskhigh

Mismatches in inductance, Q, and SRF are common among potential alternatives.

Package risklow

Most alternatives use the same standard 0603 package.

Sourcing riskmedium

Alternatives may have different availability or lifecycle statuses.

Can it be replaced directly?

No direct, one-to-one replacement for LQW18AN82NG00D has been identified. All candidates have parametric differences requiring engineering review.

Best replacement path

For applications tolerant of lower inductance, LQW18AN68NJ00D offers superior Q, SRF, and current. If 82nH is mandatory, LQG18HN82NJ00D is an option but with significant performance downgrades.

Main risk

The main risk is performance degradation in RF applications due to mismatches in inductance, Q-factor, and Self-Resonant Frequency (SRF).

Recommended alternatives

Offers better performance (Q, SRF, DCR, Current) but has a lower inductance value of 68nH.
