Is there a pin-compatible replacement for LQW15AN9N1G00D?

Yes, several parts like LQW15AN9N5G00D and LQW15AN10NG80D use the same 0402 package and pin configuration. However, they are not electrically identical, so they are considered functional or parametric alternatives, not direct drop-in replacements.

What risks should I check before replacing LQW15AN9N1G00D?

Before replacing, you must verify the impact of any change in inductance on your circuit's performance, especially in RF applications. Also check the rated current, DC resistance (DCR), Q-factor, and self-resonant frequency (SRF) to ensure they meet your design requirements.

AI replacement insight

Electrical riskmedium

Inductance deviation affects circuit tuning and performance. SRF, Q, and DCR must also be checked.

Package risklow

Many alternatives share the same 0402 package, ensuring physical compatibility.

Can it be replaced directly?

No verified drop-in replacement exists. However, several Murata parts in the same LQW15 series, like LQW15AN9N5G00D, are strong functional alternatives with the same 0402 package but require review of minor parametric differences.

Best replacement path

LQW15AN9N5G00D is the closest functional alternative, with nearly identical specs except for a slightly higher inductance of 9.5nH.

Main risk

The primary risk is a change in inductance, which can shift the operating point of RF filters, matching networks, and oscillators. Careful validation is required.

Recommended alternatives

A close functional alternative with identical package and ratings, but slightly higher inductance.
