What risks should I check before replacing MLG1005S1N3BT000?

Key risks include changes in inductance value, a lower Self-Resonant Frequency (SRF) which can affect high-frequency performance, and higher DC Resistance (DCR) which increases power loss.

AI replacement insight

Electrical risklow

Multiple candidates meet or exceed key electrical specs.

Package risklow

The 0402 (1005) package is a widely available industry standard.

Can it be replaced directly?

Direct replacement for MLG1005S1N3BT000 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

LQW15AN1N3C10D from Murata offers a potential upgrade path with identical inductance, higher current rating, and significantly better DCR and SRF.

Main risk

The main risk is ensuring the substitute's Self-Resonant Frequency (SRF) is sufficient for the application's operating frequency.

Recommended alternatives

A pin-compatible alternative from Murata with higher current rating, lower DCR, and higher SRF.
