Is there a pin-compatible replacement for LQW15AN30NG00D?

Several parts like LQW15AN27NG00D and LQW15AN33NG80D share the same 0402 package and pinout. However, their inductance values differ from the original, so they are not direct electrical drop-in replacements. Always verify performance in your application.

What risks should I check before replacing LQW15AN30NG00D?

The main risk is the inductance deviation, which can shift filter center frequencies or disrupt impedance matching in RF circuits. Also check for changes in Self-Resonant Frequency (SRF), Q factor, and DC Resistance (DCR) to ensure high-frequency performance and efficiency are not compromised.

AI replacement insight

Electrical riskmedium

Inductance deviation in all candidates requires circuit validation.

Package risklow

Several candidates match the 0402 package, ensuring physical compatibility.

Can it be replaced directly?

No direct drop-in replacement with identical inductance has been identified. All close candidates have different inductance values requiring engineering review.

Best replacement path

Consider LQW15AN27NG00D for similar performance or LQW15AN33NG80D for a higher current rating, but both require verifying the impact of the inductance change.

Main risk

The primary risk is the change in inductance value, which can detune RF circuits, alter filter characteristics, or affect impedance matching.

Recommended alternatives

Same 0402 package with higher current rating but 10% higher inductance.
