• Storage area network infrastructure

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Availability is restricted, and current stock levels are limited or unavailable through standard channels. Verification of end-of-life status and alternative sourcing strategies is required before integration into new designs.

Selection Notes

Engineers should evaluate this part only for maintenance or legacy system upgrades due to its discontinued status. New designs must consider modern replacements that offer updated power efficiency and compliance with current environmental regulations, as this specific variant lacks RoHS certification.

Part Context

This part belongs to the 89H24NT24G2 series of PCIe switches from Renesas Electronics. It shares architectural similarities with other models in the family but is distinguished by its specific pinout, packaging configuration, and thermal characteristics defined by the FCBGA-324 form factor.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct pin-to-pin replacements may not exist; functional equivalents require careful verification of lane counts and protocol compatibility.
