Procurement Notes

This component is listed as obsolete with no samples or stock available from the manufacturer. Verification of end-of-life status and discontinuation notifications is essential before design finalization. Sourcing should focus on identifying qualified replacement parts rather than attempting procurement of this specific discontinued part number.

Selection Notes

Engineers selecting this component must account for its obsolete status. Design reviews should prioritize migration strategies to supported alternatives within the same product family or newer generations that offer equivalent lane counts and port configurations while ensuring long-term supply availability.
