Procurement Notes

Verify the specific revision status when ordering, as Pulse Electronics has implemented part numbering changes for open construction products. Confirm that the new thermoplastic case with inserted pins meets your board layout requirements, as the header design modification does not affect fit or function but requires updated part identification for traceability.

Selection Notes

Select this component for home phone networking systems requiring compatibility with Coppegate's HPNA3 chipset. Ensure the surface mount package dimensions of 5.33 x 8.38 x 3.99 mm fit within the designated area on the printed circuit board. Consider the 177µH inductance and 1.33:1 turns ratio for signal integrity in data and voice coupling scenarios.

Part Context

This component belongs to the family of audio and signal transformers produced by Pulse Electronics Corporation. It is categorized under telecom transformers, specifically tailored for home phone networking uses. The product line includes variations such as the B6105NL, which shares similar functional characteristics but may differ in packaging or lead-free status.

Replacement Considerations

Pulse Electronics issued a Product Change Notification regarding header design and part numbering revisions. Verify if existing inventory needs replacement due to these administrative changes, although the internal assembly and functionality remain unchanged. Check for updated part numbers assigned during the transition period.
