Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance details as sources indicate non-compliance. Validate package integrity and moisture sensitivity handling procedures before assembly. Cross-reference datasheet revisions to ensure compatibility with current design requirements.

Selection Notes

Select this component for designs requiring 24-lane PCIe Gen2 connectivity in a compact FCBGA form factor. Ensure power delivery networks accommodate 1 V, 2.5 V, and 3.3 V rails. Verify thermal management strategies for the specified operating temperature range. Consider legacy support needs given the discontinued status of the part number.

Part Context

This part belongs to the Renesas 89HPES24T3G2 family of PCIe switches. It shares architectural similarities with other variants like the 89HPES24T3G2ZCAL8 but differs in packaging and specific pinout configurations. The ZBHLG8 suffix denotes specific lead-free and tray packaging attributes distinct from reel-based alternatives.

Replacement Considerations

Public confirmed substitute part numbers are not available. The component is listed as obsolete or end-of-life. Designers should evaluate newer generations of PCIe switches from Renesas or other manufacturers that offer equivalent lane counts and port densities.
