Is there a pin-compatible replacement for PRS6045-470MT?

Parts like PRS6045-150MT are pin-compatible in package (6045), but not electrically compatible due to different inductance. They are not drop-in replacements.

What risks should I check before replacing PRS6045-470MT?

Key risks are changes in inductance, saturation current (Isat), and DC Resistance (DCR). A different inductance will affect the ripple current and stability of a DC-DC converter.

AI replacement insight

Electrical riskhigh

Inductance mismatch requires circuit redesign and validation.

Package risklow

Alternatives from the same series are form-fit compatible.

Can it be replaced directly?

No direct, drop-in replacement with matching key parameters has been identified. All alternatives require engineering validation.

Best replacement path

Evaluate other inductors in the Fenghua PRS6045 series, which share the same package but have different electrical values.

Main risk

The primary risk is inductance mismatch, which will alter the performance of a switching regulator, potentially causing instability or inefficiency.

Recommended alternatives

A form-fit alternate from the same series with lower inductance but higher current rating and lower DCR.
