Is there a pin-compatible replacement for LQW15AN5N6C10D?

Yes, several parts like LQW15AN6N2B80D share the same 0402 package and are pin-compatible. However, none are exact electrical drop-in replacements, primarily due to different inductance values.

What risks should I check before replacing LQW15AN5N6C10D?

The main risk is the change in inductance, which can affect the performance of tuned RF circuits. You must verify if your design can tolerate a higher inductance. Also check for any changes in DCR and SRF.

AI replacement insight

Electrical riskmedium

Inductance deviation in all candidates requires circuit re-evaluation.

Package risklow

All viable candidates share the same 0402 package, ensuring physical compatibility.

Can it be replaced directly?

No direct drop-in replacement was found. All viable alternatives have a different inductance value, requiring engineering review.

Best replacement path

LQW15AN6N2B80D is the most promising alternative, offering double the current rating with closely matched DCR and SRF. However, its 11% higher inductance must be validated in the application.

Main risk

The primary risk is inductance mismatch, which can detune RF filters, matching networks, or oscillators, potentially causing circuit failure.

Recommended alternatives

A potential alternative with double the current rating, but higher inductance requires review.
