Is there a pin-compatible replacement for LQW15AN10NG00D?

Yes, several inductors share the 0402 package, making them physically compatible. However, no direct drop-in replacement with identical electrical performance has been identified. Candidates like LQG15HS10NJ02D require careful review of RF performance.

What risks should I check before replacing LQW15AN10NG00D?

Key risks include changes in circuit impedance, increased power loss from higher DCR, and reduced performance at high frequencies due to lower SRF and Q-factor. Always verify the substitute's performance in the actual application.

LQW15AN10NG00D Alternatives, Datasheet & Cross Reference | Murata Manufacturing Co., Ltd.

The Murata LQW15AN10NG00D is a 10nH, 500mA wirewound inductor in a 0402 package, designed for high-frequency RF circuits. Finding a substitute requires matching inductance, current rating, DCR, and self-resonant frequency (SRF).

AI replacement insight

Electrical riskmedium

Substitutes have different DCR, Q, SRF, or inductance, impacting RF circuit tuning and efficiency.

Package risklow

All viable candidates use the same 0402 package, ensuring form and fit compatibility.

Sourcing risklow

The target and alternatives are common parts from a major manufacturer, Murata.

Can it be replaced directly?

No direct drop-in replacement has been identified. All alternatives require engineering review due to parametric differences in inductance, DCR, or SRF.

Best replacement path

Use a part from the same Murata LQW15AN series if inductance can be adjusted, like LQW15AN8N2G00D. Otherwise, consider LQG15HS10NJ02D but verify RF performance.

Main risk

The main risk is performance degradation in RF circuits due to differences in DCR, Q-factor, and SRF between the target and potential substitutes.

Recommended alternatives

A similar 0402 wirewound inductor with better current/DCR but lower inductance (8.2nH).

Application & sourcing insights

Questions & answers

The best alternative depends on circuit tolerance. For applications that can accept higher resistance and lower SRF, Murata's LQG15HS10NJ02D is a functional option. If a slightly lower inductance (8.2nH) is permissible, LQW15AN8N2G00D offers better DCR and current.
