Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity as the unit utilizes a FCBGA-484 form factor. Check for moisture sensitivity indicators prior to installation. Ensure compatibility with existing PCB layouts designed for this specific pin configuration and thermal requirements.

Selection Notes

Select this model when requiring 22 PCIe Gen1 lanes with 16 independent ports. The industrial temperature grade (-40°C to +85°C) suits harsh environments. Consider the FCBGA-484 package constraints during mechanical design. Evaluate power budget against the specified voltage rails of 1V, 2.5V, and 3.3V for proper decoupling strategies.

Part Context

This part belongs to the 89PES22H16 series of PCIe switches manufactured by Renesas Electronics (formerly IDT). It serves as a core component for expanding PCIe connectivity in complex computing systems. The ZABRI suffix denotes specific packaging and temperature characteristics within the broader product family.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. The component is listed as obsolete. Designers should evaluate newer generations of PCIe switches from the manufacturer or compatible third-party alternatives that match the lane count and port configuration.
