AI replacement insight

Electrical riskmedium

Inductance and SRF changes require circuit validation.

Package risklow

All top candidates share the same 0402 package.

Sourcing risklow

Multiple alternatives are available from the same manufacturer.

Can it be replaced directly?

No exact direct replacement is identified. The closest options require review, primarily for changes in inductance and self-resonant frequency (SRF).

Best replacement path

The best path is to evaluate LQW15AN3N9B80D, which offers upgraded electrical performance in a matching package, provided the ~9% lower inductance is acceptable for the application.

Main risk

The main risk is a change in inductance or a lower Self-Resonant Frequency (SRF), which can detune RF circuits or limit high-frequency operation.

Recommended alternatives

Potential upgrade with higher current and lower DCR in the same package, but with a slightly lower inductance of 3.9nH.
