Specialized Procurement Notes

This component is officially listed as obsolete or discontinued by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or end-of-life notices. Compliance with RoHS directives varies by specific production batch; datasheet verification is essential before procurement to ensure regulatory adherence for intended deployment.

Specialized Selection Notes

Engineers should evaluate the 324-FCBGA footprint constraints and 19x19 mm package dimensions during PCB layout. The 3.3V power supply requirement must be integrated into the power management design. Moisture sensitivity level 4 necessitates strict handling and storage protocols to prevent damage prior to soldering. Compatibility with PCIe Gen2 standards should be confirmed against system interface requirements.

Specialized Part Context

This part belongs to the 89HPES16T4 family of PCI Express switches from Renesas. It shares architectural similarities with other members like the 89HPES16T4G2ZABX8 but differs in port count and package type. The ZCALG suffix indicates specific packaging and material configurations distinct from other variants in the series.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the component is obsolete, engineers must consult official Renesas discontinuance notices or technical support for validated replacement recommendations.
