Is there a pin-compatible replacement for LQW15AN12NG80D?

Several parts share the same 0402 package and 2-pin layout, making them physically compatible. However, no identified part is electrically identical. All require engineering validation due to differences in current rating, inductance, or other parameters.

What risks should I check before replacing LQW15AN12NG80D?

Primarily, verify the circuit's minimum required current rating; many alternatives are rated for less than half the target's 1.24A. Also, confirm the acceptable inductance tolerance, as some candidates have different values (e.g., 10nH or 11nH).

Finding a substitute for the Murata LQW15AN12NG80D 12nH inductor requires careful review of current rating and inductance. While some parts match the 0402 package, key electrical parameters often differ.

AI replacement insight

Electrical riskhigh

Most alternatives have much lower current ratings or different inductance values.

Package risklow

All viable candidates are in the same 0402 package.

Can it be replaced directly?

No direct, drop-in replacement was found. All candidates have significant parametric differences, primarily in current rating or inductance.

Best replacement path

Find a 12nH, 0402 inductor with a current rating of at least 1.24A. LQW15AN10NG80D is an option if 10nH inductance is acceptable.

Main risk

The main risk is using an inductor with a lower current rating, which can lead to overheating and failure.

Recommended alternatives

Offers higher current and lower DCR, but inductance is lower at 10nH.
