Procurement Notes

Verify the specific suffix 'LB' against official Broadcom documentation to confirm pinout compatibility and thermal specifications. Ensure the ordering quantity aligns with manufacturer minimum order requirements. Confirm RoHS compliance status through the latest product change notifications before finalizing procurement contracts.

Selection Notes

Select this component when a fixed port count of 24 Gigabit Ethernet interfaces is required. Evaluate thermal dissipation requirements for the FBGA package in dense chassis designs. Compare against alternative Broadcom models if higher port density or advanced Layer 3 routing features are necessary for the target application.

Part Context

This part belongs to the Broadcom BCM56334 series of Gigabit Ethernet switches. It shares architectural similarities with other members like the BCM56334B1KFSBLG but differs in specific packaging or operational parameters defined by the suffix. It serves as a foundational building block for scalable Ethernet networks.

Replacement Considerations
