Procurement Notes

This component is officially listed as obsolete or end-of-life by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or alternative packaging types such as tape and reel variants. Confirm RoHS3 compliance and specific suffix designations when sourcing replacements.

Selection Notes

Select this part for applications requiring 12-port PCIe Gen2 connectivity with non-blocking throughput. Ensure the design accommodates the 324-FCBGA footprint and thermal requirements for the commercial temperature grade. Verify that the host system supports the required voltage domains and MSL handling procedures during assembly.

Part Context

This device belongs to the 89H12NT12G2 series of PCIe switches. It shares architectural similarities with other models in the family, such as the 89H16NT16G2, but differs in lane count and port configuration. The ZCHLGI8 suffix indicates specific packaging and material attributes defined by Renesas.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consider evaluating the 89H16NT16G2ZCHLGI8 for higher port density or consulting Renesas for current active portfolio alternatives.
