Procurement Notes

This component is officially classified as obsolete or end-of-life by the manufacturer. Verification of availability requires checking specific distributor stock levels, as standard manufacturing supply has ceased. Buyers must confirm the exact suffix variations and lead times directly with authorized suppliers before procurement planning.

Selection Notes

Engineers should verify compatibility with existing root complexes and microprocessors when integrating this switch. The 676-FCBGA package requires appropriate PCB layout considerations for thermal management and signal integrity. Alternative solutions within the Renesas portfolio should be evaluated for new designs due to the discontinued status of this specific part number.

Part Context
