• Designed for high-density network interface applications

Applications

• High-port-count Ethernet switches
• Network infrastructure equipment requiring multiple physical layer interfaces
• Industrial networking systems with dense port requirements

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Availability is restricted to existing stock or secondary market sources. Verify authenticity and storage history due to moisture sensitivity constraints. Confirm end-of-life status before design finalization to ensure long-term supply chain stability.

Selection Notes

Consider this part only for maintenance or legacy system upgrades where original specifications are mandatory. New designs should evaluate current-generation Broadcom Ethernet transceivers with equivalent channel counts. Ensure compatibility with existing PCB layouts and firmware drivers if replacing older variants.

Part Context

Broadcom Limited produces a range of Ethernet PHY and transceiver solutions for data center and enterprise networking. The B5082 series targets applications requiring multiple independent Ethernet links within a single package. This specific variant represents an earlier generation octal solution now superseded by newer technologies.

Replacement Considerations

No direct public substitute part numbers are confirmed for this obsolete component. Evaluate Broadcom's current octal Ethernet transceiver portfolio for functional equivalents. Cross-reference pinouts and electrical characteristics carefully when selecting alternative devices.
