Is there a pin-compatible replacement for LQW15AN18NG00D?

No direct pin-for-pin replacement with identical key parameters was identified. LQW15AN15NG00D is pin-compatible in the same 0402 package but has a different inductance value (15nH vs 18nH) which requires engineering review.

What risks should I check before replacing LQW15AN18NG00D?

Key risks include package size mismatch, which requires a PCB layout change, and inductance value differences, which will affect the circuit's frequency response. Always verify DC resistance (DCR), rated current, and self-resonant frequency (SRF).

AI replacement insight

Electrical riskhigh

Inductance is a critical parameter in RF circuits; deviation requires redesign or validation.

Package riskhigh

Using a different package size (e.g., 0603 for a 0402 layout) is not possible without a board revision.

Sourcing risklow

Similar parts are available from the same manufacturer and other vendors.

Can it be replaced directly?

There is no known direct, drop-in replacement for the LQW15AN18NG00D with identical key specifications.

Best replacement path

For new PCB layouts, consider the electrically superior LQW18AN18NG00D in a 0603 package. For existing 0402 layouts, re-evaluate if a 15nH inductor like LQW15AN15NG00D is acceptable.

Main risk

The primary risks are physical package mismatch or electrical inductance mismatch, both requiring engineering validation.

Recommended alternatives

Same package and manufacturer, but lower inductance (15nH vs 18nH). Offers higher current and lower DCR.
