Is there a pin-compatible replacement for LQW15AN2N2C10D?

Yes, several 0402 inductors are pin-compatible, including parts from Fenghua and Sunlord. However, none of the identified candidates match the high-performance electrical characteristics of the Murata part.

What risks should I check before replacing LQW15AN2N2C10D?

Before replacing, verify your circuit's tolerance for higher DCR (power loss), lower SRF and Q-factor (reduced RF performance), and a lower current rating (risk of overheating or failure).

LQW15AN2N2C10D Alternatives, Datasheet & Cross Reference | Murata Manufacturing Co., Ltd.

The Murata LQW15AN2N2C10D is a high-performance 2.2nH RF inductor in a 0402 package, featuring a 1A current rating, low 0.027Ω DCR, and 14GHz SRF. Finding a substitute requires matching these key RF specs.

AI replacement insight

Electrical riskhigh

Substitutes have lower current, Q, SRF and higher DCR.

Package risklow

Candidates match the 0402 package.

Can it be replaced directly?

No direct drop-in replacement was found. Alternatives like VHF100505HQ2N2ST match the inductance but have much lower performance and require circuit validation.

Best replacement path

Search for 0402 wirewound inductors with ≥1A current, DCR <0.03Ω, and SRF >10GHz. Multilayer types are unlikely to match performance.

Main risk

The primary risk is performance degradation: higher power loss (DCR), reduced high-frequency response (SRF), and lower circuit efficiency (Q-factor).

Recommended alternatives

A 2.2nH inductor in the same 0402 package, but with lower performance in current, DCR, Q, and SRF.
