Procurement Notes

Verify RoHS compliance status as sources indicate conflicting information regarding regulatory adherence. Confirm current stock availability since some distributors list the item as discontinued or out of stock. Check for recent Product Change Notifications that may affect part specifications or packaging details before finalizing procurement orders.

Selection Notes

Select this component for designs requiring a compact, single-port 10G Base-T transformer. Ensure the PCB layout accommodates the specified surface mount footprint. Verify that the 1.5 kVrms isolation rating meets the system's safety requirements. Consider alternative packages if different mounting styles are required for the specific application.

Part Context

This part belongs to Pulse Electronics' LAN transformer family. It is specifically engineered for high-speed data transmission standards. The module integrates primary and secondary windings into a single surface mount unit. It replaces discrete transformer solutions to save board space and simplify assembly.

Replacement Considerations

Check for direct substitutes with identical pinouts and electrical characteristics. Verify compatibility with existing 10G Base-T PHY chips. Review any official end-of-life notices from the manufacturer to ensure long-term supply stability.
