Is there a pin-compatible replacement for LQW15AN33NG00D?

No direct pin-to-pin replacement with identical key parameters has been identified. Candidates in the same 0402 package, like LQW15AN24NG00D, have different inductance values and require engineering validation.

What risks should I check before replacing LQW15AN33NG00D?

Key risks include inductance deviation, which affects circuit tuning and impedance matching. Also check for changes in Self-Resonant Frequency (SRF), Q factor, and DC Resistance (DCR), as these impact high-frequency performance and efficiency.

LQW15AN33NG00D Alternatives, Datasheet & Cross Reference | Murata Manufacturing Co., Ltd.

The Murata LQW15AN33NG00D is a 33nH, 0402 wirewound inductor for high-frequency circuits. Finding a direct drop-in replacement requires matching its inductance, package, and high SRF, while alternatives may offer different parametric trade-offs.

AI replacement insight

Electrical riskhigh

Inductance mismatch in same-package options is a primary concern for circuit performance.

Package riskhigh

Electrically similar parts are in a different (larger) package, requiring a board spin.

Sourcing risklow

The target part is Active from a major manufacturer, and alternatives exist.

Can it be replaced directly?

No direct, drop-in replacement with identical key parameters has been found. All identified alternatives in the same package have different inductance values, requiring careful engineering review.

Best replacement path

If PCB space allows, using the electrically superior LQW18AN33NG00D (0603 package) is the lowest electrical risk path. If the 0402 package is mandatory, LQW15AN24NG00D is a parametric alternative requiring circuit re-evaluation for its lower inductance.

Main risk

The primary risk is inductance mismatch, which can detune RF circuits or alter filter characteristics.

Recommended alternatives

A 0402 inductor with lower inductance (24nH) but higher current rating (280mA) and lower DCR.
