Specialized Procurement Notes

This part number is classified as obsolete by the manufacturer. Verification of availability should focus on surplus or secondary market sources rather than direct distribution channels. Buyers must confirm the specific revision level and physical condition of the components, as lead times and stock levels are subject to change in the aftermarket. Compliance with RoHS standards should be verified against the specific batch documentation provided by the supplier.

Specialized Selection Notes

Engineers selecting this component should consider its status as an end-of-life product when designing new hardware. The 196-ball FCBGA package requires careful PCB layout considerations for thermal management and signal integrity. Alternative solutions within the same family or newer generations from Renesas should be evaluated for long-term supply chain stability. The industrial temperature rating makes it suitable for harsh environments, but design margins must account for aging effects in discontinued silicon.

Specialized Part Context

The 89HT0816APZCBLGI8 belongs to the IDT 89HT series of PCIe retimers, which were widely used before Renesas consolidated its interface portfolio. This specific suffix indicates the industrial temperature grade and tray packaging variant. It serves as a critical link extender for PCIe Gen3 links, ensuring signal quality over longer traces or complex backplanes in server and networking equipment architectures.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Engineers should consult Renesas official documentation for recommended upgrades or cross-references to newer PCIe retimer families.
