Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or end-of-life inventory. Sourcing should prioritize verified legacy channels due to discontinuation status.

Selection Notes

Select this part for designs requiring 16-lane PCIe Gen2 switching with non-blocking throughput. Ensure compatibility with 1V, 2.5V, and 3.3V power domains. Verify that the 324-FCBGA footprint fits the PCB layout constraints before finalizing the design.

Part Context

The 89H16NT16G2ZAHLG8 belongs to the IDT 89HPES16NT16G2 family of PCI Express switches. It was originally manufactured by Integrated Device Technology (IDT), which was acquired by Renesas Electronics. This specific suffix denotes the tray packaging variant with lead-free composition.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, alternative solutions require manual evaluation of current market offerings for equivalent 16-lane PCIe Gen2 switches.
