Procurement Notes

This component is classified as obsolete or end-of-life. Verification of current availability through authorized distributors is required. Check for alternative packaging options such as tape and reel variants if tray quantities are unavailable. Confirm RoHS compliance status and moisture sensitivity level prior to integration into manufacturing processes.

Selection Notes

Select this part for designs requiring a 12-port PCIe Gen2 switch with non-blocking performance. Ensure the PCB layout accommodates the 676-FCBGA package size. Verify that the system root complex supports the necessary link training protocols. Consider thermal management requirements due to the density of active lanes within the specified industrial temperature range.

Part Context

This part belongs to the IDT 89HPES48H12G2 family of PCIe switches. It shares architectural similarities with other members like the 89H48H12G2 series but may differ in specific pinouts or electrical characteristics. It serves as a critical node for expanding PCIe connectivity in enterprise-grade hardware platforms requiring high bandwidth aggregation.

Replacement Considerations

Public confirmed substitute part numbers are not available for this obsolete component. Designers should evaluate newer generations of PCIe switches from Renesas or other vendors that offer compatible port counts and lane speeds.
