Specialized Procurement Notes

Verify the specific suffix 'VF' against the manufacturer's official datasheet to confirm pinout compatibility and temperature grade. Ensure that the 48-HTQFP package footprint matches the design layout. Cross-reference the RoHS status and moisture sensitivity level requirements with assembly specifications before procurement.

Specialized Selection Notes

Select this component when a reliable 10/100 Mbps solution with integrated diagnostics is required. Consider the -55°C to 125°C operating range for harsh environments. Verify interface compatibility with the host MAC controller, specifically regarding MII or RMII mode selection. Check power supply constraints against the 3V to 3.6V requirement.

Specialized Part Context

The DP83858VF belongs to the PHYTER family of Ethernet transceivers from Texas Instruments. This series is designed for high reliability and low power in industrial and automotive applications. It complements other PHYTER devices by offering specific feature sets tailored for Fast Ethernet connectivity with enhanced diagnostic tools.

Specialized Replacement Considerations

Check for direct substitutes within the DP83848 or DP83865 families if pin-to-pin compatibility is confirmed. Verify functional equivalence regarding interface support and power requirements before substitution.
