Is there a pin-compatible replacement for LQW18ANR47G00D?

No exact pin-compatible replacement with identical key parameters was found. Parts like LQW18ANR39G00D are in the same 0603 package but have different inductance values, so they are not drop-in replacements.

What risks should I check before replacing LQW18ANR47G00D?

The primary risks are inductance mismatch, which can detune filters or matching networks, and a lower Self-Resonant Frequency (SRF), which can degrade high-frequency performance.

LQW18ANR47G00D Alternatives, Datasheet & Cross Reference | Murata Manufacturing Co., Ltd.

Finding a substitute for the Murata LQW18ANR47G00D 470nH RF inductor requires matching inductance, SRF, and the 0603 package. Alternatives may require design adjustments.

AI replacement insight

Electrical riskmedium

Inductance and SRF differences in candidates require circuit validation.

Package risklow

Alternatives in the same 0603 package are available, minimizing layout changes.

Can it be replaced directly?

No direct, drop-in replacement with identical key parameters was found. Candidates in the same package exist but differ in inductance, requiring review.

Best replacement path

Find a 470nH RF inductor in a 0603 package with an SRF of 700MHz or higher. Alternatives with different inductance require circuit analysis.

Main risk

The main risks are changes in inductance and a lower Self-Resonant Frequency (SRF), which can detune RF circuits or affect performance.

Recommended alternatives

Same 0603 package and tolerance with better SRF, but inductance is lower at 390nH.
