Procurement Notes

Verify the specific suffix 'FNL' against the original design requirements to ensure compatibility with existing PCB footprints and manufacturing processes. Confirm that the surface-mount variant meets all mechanical constraints of the target assembly line. Cross-reference datasheet revisions to ensure compliance with current environmental regulations such as RoHS3 before finalizing procurement orders.

Selection Notes

Select this component when designing for 10/100 Base-T Ethernet interfaces requiring integrated TX/RX isolation. Ensure the operating temperature range of 0°C to 70°C aligns with the system environment. Verify that the physical dimensions fit within the allocated board space and that the surface-mount technology matches the fabrication capabilities.

Part Context

This part belongs to Pulse Electronics' LAN transformer portfolio, specifically engineered for high-speed data communication networks. It serves as a critical isolation component between the PHY chip and the external network medium, ensuring signal integrity and electrical safety in standard Ethernet deployments.

Replacement Considerations

The H1174NL is a discontinued tube-packaged equivalent. The H1174FNLT serves as the active surface-mount replacement.
