Procurement Notes

This component is identified as obsolete or end-of-life by the manufacturer. Verification of availability should focus on distributor inventory status rather than direct manufacturing supply. Confirm RoHS compliance and package specifications against specific suffix requirements before procurement planning.

Selection Notes

Select this part for applications requiring 48 PCIe Gen2 lanes with 12 independent ports. Ensure the design supports the 676-FCBGA package dimensions. Verify thermal management capabilities for the operating temperature range. Consider the partitionable architecture needs for multi-root support in the system topology.

Part Context

This part belongs to the Renesas PES48H12G2 family of PCIe switches. It is functionally related to the 89KTPES48H12G2 evaluation board, which serves as a development platform for testing the PES48H12G2 switch functionality. The family is designed for deterministic system interconnect switching in high-performance computing environments.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the product is marked obsolete, alternative solutions require evaluating current generation PCIe switches from the manufacturer or other vendors with compatible lane counts and port configurations.
