Is there a pin-compatible replacement for LQW18AN47NG00D?

Yes, several 0603 inductors are physically compatible. Murata's LQW18AN33NG00D from the same series is pin-compatible. Cross-vendor parts like Coilcraft's 0603HP-47NXGLW share the same 0603 footprint but require datasheet verification for the exact land pattern.

What risks should I check before replacing LQW18AN47NG00D?

The main risks are changes in inductance and self-resonant frequency (SRF). A lower inductance will alter filter or oscillator behavior. A lower SRF can impact performance in high-frequency circuits. Always verify the replacement's datasheet for all key parameters.

LQW18AN47NG00D Alternatives, Datasheet & Cross Reference | Murata Manufacturing Co., Ltd.

The Murata LQW18AN47NG00D is a 47nH, 0603 wirewound inductor for high-frequency circuits. When seeking alternatives, key parameters like inductance, self-resonant frequency (SRF), and current rating must be carefully matched.

AI replacement insight
