Is there a pin-compatible replacement for LQW15AN33NG80D?

Several 0402 package inductors are physically pin-compatible, but their electrical characteristics vary significantly. A full datasheet review is required before considering any as a replacement.

What risks should I check before replacing LQW15AN33NG80D?

Key risks include lower current ratings causing overheating, different inductance values shifting circuit frequency response, and higher DC resistance (DCR) increasing power loss. Always verify these in your application.

LQW15AN33NG80D Alternatives, Datasheet & Cross Reference | Murata Manufacturing Co., Ltd.

The Murata LQW15AN33NG80D is a high-Q, 33nH wirewound inductor in a compact 0402 package, designed for high-frequency RF circuits. Finding a substitute requires careful matching of inductance, current rating, and self-resonant frequency.

AI replacement insight

Electrical riskhigh

Candidates have different inductance, current, or DCR.

Package risklow

All candidates are in the standard 0402 package.

Sourcing riskmedium

Target's high-performance specs are hard to match without compromise.

Can it be replaced directly?

No direct, one-to-one replacement has been identified. All candidates have significant parametric differences.

Best replacement path

Cross-reference to other vendors like Coilcraft's 0402HP series, but requires parametric trade-offs.

Main risk

The primary risk is finding a part with a comparable combination of high current rating (620mA) and specific inductance (33nH) in an 0402 package. Most alternatives compromise on one or the other.

Recommended alternatives

A potential downgrade with a much lower current rating (270mA vs 620mA) and higher DCR.
