Procurement Notes

Verify the current lifecycle status before procurement, as this component is designated as Not Recommended for New Designs. Confirm that existing inventory or last-time buy options meet project requirements. Ensure compatibility with existing PCB footprints and design constraints given the obsolescence notice.

Selection Notes

Select this component only for maintenance or replacement of existing designs where the specific pinout and electrical characteristics are already validated. Evaluate alternative newer generation isolators from the manufacturer for new projects to ensure long-term supply availability and updated feature sets.

Part Context

This part belongs to the ISOFACE family of digital isolators from Infineon Technologies. These devices utilize magnetic coupling technology to provide reliable signal isolation between different voltage domains. The 4DIR series is specifically designed for applications requiring multiple isolated channels with high common-mode transient immunity.

Replacement Considerations

Public confirmed substitute part numbers include 4DIR1401HAXUMA1 and 4DIR1420HAXUMA1. Verify pin compatibility and electrical specifications when substituting these equivalents.
