• Multi-protocol industrial Ethernet systems

Specialized Procurement Notes

Verify the specific suffix HRHBT against the manufacturer's datasheet to confirm the exact temperature rating and packaging configuration. Ensure compatibility with the host system's voltage levels and interface requirements before procurement. Check for moisture sensitivity level compliance during storage and handling.

Specialized Selection Notes

Select this component when extended industrial temperature operation (-40°C to +125°C) is required. It is suitable for designs needing integrated cable diagnostics and low power consumption. Verify that the host processor supports the desired interface mode (MII, RGMII, or RMII).

Specialized Part Context

This part belongs to the DP83822H series of Ethernet transceivers. It is designed for high-reliability applications requiring robust performance in electrically noisy environments. The device integrates essential PHY functions into a compact form factor suitable for space-constrained industrial and commercial boards.

Specialized Replacement Considerations

The DP83822IRHBT is a related variant within the same family. Verify if the lower operating temperature limit of the alternative meets the application requirements. Confirm pinout and register compatibility before substitution.
