Is there a pin-compatible replacement for LQW15AN2N4B00D?

There is no confirmed pin-to-pin replacement. LQW15AN2N4C00D is a strong form-fit-function candidate with the same package, pinout, and key electrical values, but its inductance tolerance is wider. Engineering validation is required.

What risks should I check before replacing LQW15AN2N4B00D?

Before replacing, primarily check the impact of any change in inductance and its tolerance on your circuit's performance, especially in RF or timing-sensitive applications. Also, verify that any changes in DC resistance (DCR) or Q-factor are within your design's limits.

LQW15AN2N4B00D Alternatives, Datasheet & Cross Reference | Murata Manufacturing Co., Ltd.

Finding a substitute for the Murata LQW15AN2N4B00D 2.4nH inductor requires careful review of electrical parameters. While several alternatives exist in the same 0402 package, they often differ in inductance, tolerance, or Q-factor, necessitating engineering validation.

AI replacement insight

Electrical riskmedium

Changes in inductance, tolerance, or Q-factor can affect circuit tuning and stability.

Package risklow

All reviewed candidates use the same 0402 package, ensuring physical compatibility.

Can it be replaced directly?

No exact drop-in replacement has been identified. The closest option, LQW15AN2N4C00D, has a looser inductance tolerance that requires engineering review.

Best replacement path

The closest alternative is LQW15AN2N4C00D, which matches all key specs except for a slightly looser inductance tolerance. If the application is sensitive to this, consider functional alternatives like LQW15AN2N2B8ZD, but be prepared to validate the change in inductance from 2.4nH to 2.2nH.

Main risk

The primary risk is a mismatch in inductance or tolerance, which can detune high-frequency circuits, impacting performance and compliance.

Recommended alternatives

A strong match with identical package, inductance, and current, but slightly looser tolerance.
