Procurement Notes

Verify the manufacturer designation as TDK Electronics or EPCOS, noting that EPCOS was renamed to TDK Electronics. Confirm the specific suffix A003 matches the required 10/100 Base-T specification rather than other variants in the B78476A series. Ensure the package dimensions align with the specified footprint requirements.

Selection Notes

Select this component for designs requiring 10/100 Base-T connectivity with extended temperature tolerance. Verify that the 350 µH inductance value meets the circuit's impedance matching requirements. Check that the surface mount package size fits within the available PCB area constraints.

Part Context

This part belongs to the B78476A series of magnetic modules designed for LAN applications. The series includes various configurations for different Ethernet standards. TDK acquired EPCOS, unifying the product portfolio under the TDK brand while maintaining the original part numbering structure.

Replacement Considerations

Consult official TDK documentation for direct substitutes within the B78476A series. Verify compatibility with existing PCB footprints and electrical parameters before replacing.
