Procurement Notes

Verify the specific suffix variant required for your design, as options like 100B-1027T or 100B-1027XT may differ in packaging or tape-and-reel specifications. Confirm that the 1.5 kV isolation rating meets your system's safety requirements. Ensure the SMT footprint matches your PCB layout constraints before finalizing orders.

Selection Notes

Select this component when designing for standard 10/100 Mbps Ethernet connectivity requiring a 1:1 transformation ratio. Consider the physical size constraints of the 25.40mm x 12.70mm package against available board space. Evaluate the thermal performance and mounting stability associated with surface mount integration in your specific enclosure environment.

Part Context

This part belongs to the iNRCORE LAN transformer family, which provides magnetics solutions for various Ethernet speeds. The 100B series specifically targets base-T applications, distinguishing itself from higher-speed Gigabit variants. It serves as a critical passive component for signal integrity and isolation in legacy and industrial networking hardware.

Replacement Considerations

Direct substitutes within the same manufacturer line include the 100B-1027T and 100B-1027XT variants. These alternatives share identical core electrical characteristics but may vary in shipping configuration or specific reel packaging details. Cross-reference pinouts and mechanical drawings to ensure compatibility.
