Is there a pin-compatible replacement for LQG15HS56NJ02D?

No, a fully pin-compatible, drop-in replacement with identical or better specifications has not been found. The closest option, LQW15AN56NJ00D, has the same 0402 package but a lower current rating and different internal construction, which requires engineering review.

What risks should I check before replacing LQG15HS56NJ02D?

Before replacing, verify three main risks: 1) Package mismatch, as some alternatives are larger and require a board redesign. 2) Electrical stress, as some same-size options have a lower current rating. 3) RF performance, as candidates are wirewound, unlike the target's multilayer construction, affecting Q and SRF.

Package riskhigh

Some alternatives are in a larger 0603 package, requiring a PCB redesign.

Electrical riskmedium

Candidates may have lower current ratings or different RF characteristics due to construction differences.

Can it be replaced directly?

No direct, drop-in replacement has been identified. All candidates have significant caveats, such as a different package size or a lower current rating.

Best replacement path

If board layout cannot change, LQW15AN56NJ00D is an option but requires verifying the lower 200mA current rating. If a board redesign is possible, LQW18AN56NG00D offers superior electrical performance.

Main risk

The primary risk is the change in inductor construction from multilayer (target) to wirewound (candidates), which alters high-frequency characteristics like Q and SRF and may impact RF circuit performance.

Recommended alternatives

Electrically superior alternative with matching inductance, but in a larger 0603 package.
