Procurement Notes
This component is officially discontinued and listed as End-of-Life by Broadcom Limited. Procurement is restricted to remaining stock or secondary market sources. Verify authenticity carefully due to EOL status. Check for Product Change Notifications regarding potential obsolescence impacts. Availability is limited and subject to existing inventory constraints rather than active manufacturing.
Selection Notes
Select this part only if legacy compatibility with the BCM56546 family is required. Evaluate alternative Broadcom switches for new designs due to discontinuation. Ensure system requirements align with the 48+4 port architecture and fast stacking features. Consider thermal and power management implications of the BGA package in the final design.
Part Context
The BCM56546KB0KFSBLG belongs to the Broadcom BCM56546 series of Ethernet switches. It is designed for enterprise-grade networking solutions requiring high port density and advanced power management features. The KB0 suffix indicates specific packaging and temperature range characteristics within the broader BCM56546 product line.
Replacement Considerations
No public confirmed substitute part numbers are available for this discontinued component. Engineers should consult Broadcom's current portfolio for modern equivalents that match port count and feature requirements.
