Procurement Notes
Verify component status as it may be marked Not Recommended for New Designs; confirm availability through authorized distributors. Ensure compliance with RoHS directives and check for equivalent active parts like H1302NL if current stock is limited. Validate datasheet revisions before finalizing procurement orders.
Selection Notes
Select this component for designs requiring 10/100 Base-T isolation with specific 350µH inductance requirements. Consider the physical footprint constraints of the SMD package during PCB layout. Verify thermal performance within the specified operating temperature range for the intended application environment.
Part Context
This part belongs to the Pulse Electronics LAN transformer series, specifically engineered for high-speed data communication interfaces. It serves as a critical isolation component in Ethernet PHY circuits, ensuring signal integrity and electrical safety between the transceiver and the magnetics network.
Replacement Considerations
The H1302NL is identified as a direct substitute offering the same form, fit, and function. Verify pin compatibility and electrical parameters when transitioning from the H1302FNL to ensure seamless integration without redesigning the host circuit board.
