Procurement Notes
Verify current availability status as this component is listed as obsolete or discontinued in official distributor records. Confirm end-of-life timelines and last-time-buy windows with authorized suppliers before committing to procurement plans. Ensure alternative sourcing strategies are established due to potential supply chain constraints associated with discontinued part numbers.
Selection Notes
Select this component specifically for legacy 10/100Base-T single-port implementations requiring specific impedance matching characteristics. Evaluate physical footprint compatibility with existing PCB layouts due to its defined surface-mount dimensions. Consider obsolescence status when designing new products, prioritizing future-proof alternatives unless maintaining backward compatibility with existing hardware architectures.
Part Context
This part belongs to Pulse Electronics' portfolio of audio and signal transformers, specifically categorized under LAN transformers and pulse transformers. It serves as a passive magnetic component facilitating electrical isolation between network transceivers and physical media connectors. The product line focuses on providing reliable signal coupling for standard Ethernet protocols in embedded systems.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, direct pin-compatible replacements may require engineering validation. Consult manufacturer technical support for recommended cross-reference components suitable for 10/100Base-T single-port applications.
