Procurement Notes

This component is officially classified as obsolete by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or end-of-life alternatives. Compliance with RoHS directives should be confirmed via specific datasheet revisions, as lead-free status varies by suffix. Engineering samples are generally unavailable for discontinued parts.

Selection Notes

Select this part for applications requiring 22 PCIe Gen1 lanes with 16 independent ports. Ensure compatibility with FCBGA-484 package constraints on the PCB layout. Verify that the system design supports the required voltage levels and thermal dissipation for industrial temperature grades associated with the 'I' suffix designation.

Part Context

Part of the 89HPES22H16 series from Renesas (formerly IDT), designed for PCIe Gen1 interconnects. It serves as a core switching element in complex server and storage systems requiring high throughput and multi-root capabilities. The ZABL suffix indicates specific packaging and temperature grade variations within the product line.

Replacement Considerations

Official substitutes include other variants within the 89HPES22H16 family such as 89HPES22H16ZABC or 89HPES22H16ZABCI, depending on package and temperature requirements. Cross-generation replacements may require architectural review due to PCIe protocol differences.
