Procurement Notes

Verify the specific datasheet revision to ensure compatibility with current manufacturing standards. Confirm that the non-PoE designation aligns with the power delivery requirements of the target application. Check for RoHS compliance documentation if environmental regulations apply to the deployment region. Ensure the SMD package dimensions fit the designated footprint on the printed circuit board layout.

Selection Notes

Select this component when designing for standard 10/100 Mbps Ethernet connectivity without PoE requirements. The dual-port architecture reduces component count compared to single-port alternatives. Verify that the 1.5 kV isolation voltage meets the safety requirements of the system. Consider the operating temperature range of -40°C to +85°C for industrial or wide-temperature environments.
