Is there a pin-compatible replacement for LQG15HS47NJ02D?

LQW15AN47NG00D shares the same 0402 package and 47nH inductance but has a lower current rating (210mA vs 300mA). It is not a direct drop-in replacement and requires engineering review.

What risks should I check before replacing LQG15HS47NJ02D?

Key risks include package size mismatch, which requires a new PCB layout, and lower current rating or higher DC resistance, which can cause component failure or performance degradation. Always verify these in your application.

AI replacement insight

Package riskhigh

A functional upgrade requires a larger 0603 package, which is not a drop-in fit.

Electrical riskmedium

The same-package alternative has a significantly lower current rating, posing a reliability risk.

Can it be replaced directly?

No direct, drop-in replacement with identical or better key parameters has been identified. Alternatives have either a different package or weaker electrical specifications.

Best replacement path

For board revisions, consider the electrically superior LQW18AN47NG00D in a 0603 package. For existing boards, carefully evaluate LQW15AN47NG00D, ensuring its lower current rating is acceptable.

Main risk

The primary risk is either physical incompatibility due to different package sizes or electrical overstress from using a part with a lower current rating.

Recommended alternatives

Same package and inductance, but lower current rating requires engineering review.
