Procurement Notes

This component is officially designated as End-of-Life by the manufacturer. Procurement should focus on verifying remaining stock availability through authorized distributors or approved secondary market sources. Ensure that any acquired units are genuine and match the specific suffix requirements for your design. Due to the discontinued status, long-term supply continuity cannot be guaranteed, making verification of part authenticity critical before integration into production schedules.

Selection Notes

Engineers selecting this part must account for its obsolete status when designing new products. While the ISOFACE™ family offers advanced magnetic coupling, the specific 4DIR1401HAXUMA1 variant is no longer in active production. Designers should evaluate alternative components within the same series or newer generations that provide equivalent electrical specifications and package compatibility to ensure future supply chain stability and compliance with long-term manufacturing requirements.
