Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or approved replacement alternatives. Ensure compliance with RoHS3 specifications if applicable to the specific suffix variant. Confirm moisture sensitivity level MSL 4 handling requirements during storage and assembly processes.

Selection Notes

Select this part for legacy designs requiring 16-lane PCIe Gen2 switching. Verify that the 324-FCBGA footprint matches the PCB layout. Consider the industrial temperature grade if operating in extreme environments. Evaluate alternative components if new production is required due to the obsolete status.

Part Context

This part belongs to the 89HPES16NT16G2 family of PCI Express switches. It shares core functionality with variants like 89H16NT16G2ZBHLGI but differs in lead-free status and packaging type. The family is designed for deterministic low-latency switching in complex computing systems.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineering change orders may be necessary to adopt newer Renesas PCIe switch families or third-party equivalents with compatible pinouts.
