Is there a pin-compatible replacement for FAUL1050-6R8MT?

FXL1040-6R8-M is pin-compatible as it uses the same 11.5mm x 10mm package. However, it is not a drop-in replacement due to weaker electrical specifications (Isat, DCR) and missing AEC-Q200 qualification.

What risks should I check before replacing FAUL1050-6R8MT?

Key risks include lower saturation current (Isat), which can cause inductance to drop under load, higher DC resistance (DCR), leading to increased power loss and heat, and lack of AEC-Q200 qualification if used in automotive systems.

Electrical riskhigh

Lower saturation current and higher DCR in alternatives.

Application riskhigh

Alternatives lack the target's AEC-Q200 qualification.

Package risklow

One candidate (FXL1040-6R8-M) is a form-fit match.

Can it be replaced directly?

No direct, drop-in replacement for FAUL1050-6R8MT has been identified. Alternatives require careful review of electrical and qualification differences.

Best replacement path

Consider FXL1040-6R8-M for non-automotive designs if lower Isat and higher DCR are acceptable. No direct AEC-Q200 qualified replacement was found.

Main risk

The primary risks are electrical stress from lower saturation current and increased power loss from higher DCR. For automotive applications, the lack of AEC-Q200 qualification in alternatives is a critical failure point.

Recommended alternatives

Form-fit compatible with same inductance, but has lower current ratings, higher resistance, and lacks AEC-Q200 qualification.
