Procurement Notes

Verify the specific suffix ZBHL against official datasheets to confirm package dimensions and pinout compatibility. Confirm RoHS compliance status as older variants may not meet current environmental standards. Check moisture sensitivity level requirements for storage and handling procedures before assembly.

Selection Notes

Select this model when 32 lanes and 24 ports are required for PCIe Gen2 systems. Ensure the design accommodates the 484-FCBGA footprint and thermal dissipation needs. Verify that the application requires the specific voltage levels and data rates supported by this generation of switch technology.

Part Context

This component belongs to the 89H32NT24BG2 series of PCIe switches. Variants such as 89H32NT24BG2ZCHLGI and 89H32NT24BG2ZBHLG8 share similar core functionalities but differ in packaging, lead-free status, or carrier type. The ZBHL suffix specifically denotes the tray packaging and lead-free composition within this family.

Replacement Considerations

Publicly confirmed substitute part numbers include 89H32NT24BG2ZCHLGI and 89H32NT24BG2ZBHLG8. These alternatives offer identical electrical performance but may vary in packaging format or environmental compliance specifications.
