Procurement Notes

This component is officially listed as obsolete by the manufacturer. Availability is restricted or nonexistent through standard distribution channels. Verification of end-of-life notifications and discontinuation dates is required before integration into new designs. Sourcing should focus on verified secondary market suppliers with appropriate quality assurance protocols.

Selection Notes

Designers requiring active alternatives should evaluate current-generation PCIe switches from Renesas or other vendors. Considerations must include lane count, port configuration, and power supply requirements matching the original specifications. Compatibility with existing root complex hardware and software drivers needs validation for any substitute components.

Part Context

This part belongs to the 89HPES series of PCIe Gen2 switches. It shares architectural similarities with the 89H48H12G2 but may differ in specific electrical characteristics or packaging options. The suffix ZCBLGI8 indicates specific package type, lead-free status, and industrial temperature grade variations within the product family.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult official Renesas lifecycle notices for recommended replacements or contact technical support for qualified alternative devices.
