Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Pulse Electronics or authorized distributors before procurement. Ensure the ordering suffix matches the required tape-and-reel packaging configuration. Confirm that the component meets the specific electromagnetic compatibility requirements of the target end-use equipment.

Selection Notes

Select this component when designing systems requiring integrated isolation for dual-port or multi-port Ethernet connections. It is suitable for space-constrained designs where discrete magnetics would exceed board area limits. Consider thermal management capabilities if operating near maximum temperature ratings in enclosed chassis environments.

Part Context

This part belongs to Pulse Electronics' LAN transformer module series, which provides complete magnetic solutions for various Ethernet speeds. These modules replace multiple discrete components, reducing assembly complexity and improving signal integrity compared to traditional discrete transformer implementations in standard networking hardware.

Replacement Considerations

Consult official substitution lists from Pulse Electronics for direct replacements. Verify pinout compatibility and electrical specifications against alternative quad LAN modules before integration into existing PCB layouts.
