Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact contact finish, housing color, and termination type specifications. Ensure compatibility with the target PCB or backplane design regarding board thickness and mounting hole alignment. Confirm RoHS compliance status through the latest datasheet revision before procurement. Cross-reference the part number with authorized distributors to validate authenticity and supply chain integrity.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row interface with 80 positions and a 3.96 mm pitch is required. Ensure the application environment stays within the specified -40°C to +105°C operating temperature range. Verify that the mating card edge thickness matches the 1.57 mm design parameter. Consider the panel mount requirement and vertical orientation during mechanical layout planning. Confirm that the 5 A current rating meets the electrical load requirements of the circuit design.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and configurations to suit different density requirements. The 305-080-520-502 specifically addresses needs for higher pin counts in a dual-row format. It complements other components in the same family by providing consistent mechanical and electrical standards across the product line.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC cross-reference guide for verified substitute part numbers. Ensure any replacement maintains the same 80-position count, dual-row layout, and 3.96 mm pitch. Verify that alternative options support the same 1.57 mm board thickness and panel mount style. Confirm compatibility with existing tooling and assembly processes before switching suppliers.
