Procurement Notes

Verify the specific suffix against official Pulse Electronics documentation to confirm exact packaging and lead time specifications. Ensure compatibility with RoHS3 standards and check for any recent Product Change Notifications (PCN) regarding epoxy or design modifications before finalizing procurement orders.

Selection Notes

Select this component for non-PoE 10BASE-T applications requiring surface-mount integration. Consider the 160 µH inductance and impedance matching for proper signal integrity. Verify that the operating temperature range of 0°C to +70°C meets the environmental requirements of the target system.

Part Context

This part belongs to the Pulse Electronics LAN Transformers category, specifically designed as an audio/signal transformer. It serves as a surface-mount solution for isolating data lines in standard Ethernet physical layer implementations, distinct from PoE-enabled variants.

Replacement Considerations

The E2458FNLT is identified as a parametric equivalent substitute. Verify pinout and electrical parameter alignment with official datasheets before substitution.
