Procurement Notes
Verify RoHS compliance status and current lifecycle stage before procurement, as availability may vary by region. Confirm package type matches design requirements, as suffixes indicate specific packaging formats such as cut tape or reel. Cross-reference datasheet revision dates to ensure compatibility with latest manufacturing standards. Check for alternate part numbers if original stock is limited.
Selection Notes
Select this component for standard 10Base-T isolated designs requiring low profile surface-mount integration. Ensure the 0.6 Ohm DC resistance meets circuit loss budgets. Verify that the 1.5 kV isolation rating satisfies safety requirements for the target application environment. Confirm thermal operating limits align with system enclosure constraints.
Part Context
This component belongs to Pulse Electronics' LAN isolation transformer portfolio, specifically engineered for Ethernet connectivity. It serves as a critical interface between the MAC layer and the physical medium, ensuring signal integrity and electrical safety. The product line includes variants for different Ethernet speeds and PoE configurations.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult manufacturer catalogs for direct replacements or evaluate equivalent specifications from other suppliers if discontinuation occurs.
