Procurement Notes

Verify the exact suffix configuration when sourcing replacements, as packaging and tape/reel variations may exist. Confirm current availability status due to potential lifecycle changes. Ensure compatibility with existing PCB footprints and thermal requirements. Cross-reference pin assignments with official datasheets to prevent integration errors during procurement and assembly processes.

Selection Notes

Select this component for designs requiring multi-channel PoE PD functionality with integrated switching capabilities. Consider the 36-SSOP package constraints for board space limitations. Evaluate thermal performance requirements given the operational temperature range. Verify that the input voltage range aligns with the specific PoE standard implementation in the target application environment.
