Parameter Comparison

Engineering Selection Recommendations

The MIC37502WU is the direct substitute for the MIC37502BU. Both parts share identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility. The MIC37502WU offers two significant advantages: Active product status ensures continued manufacturer support and availability, and ROHS3 compliance satisfies modern regulatory requirements for new designs and procurement cycles. The MIC37502BU's Obsolete status and RoHS non-compliance make the MIC37502WU the appropriate selection for all new applications and ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Can MIC37502WU be used as a direct replacement for MIC37502BU?

A: Yes. The MIC37502WU is electrically and mechanically equivalent to the MIC37502BU. All output voltage ranges, current ratings, protection features, and package configurations are identical. Pin compatibility is maintained.

Q: What is the difference between MIC37502BU and MIC37502WU?

A: The primary differences are product status and compliance. The MIC37502BU is Obsolete and RoHS non-compliant, while the MIC37502WU is Active and ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Why is the MIC37502BU classified as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support. The MIC37502WU represents the current production equivalent from Microchip Technology.

Q: Are there packaging differences between these parts?
