Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm contact configuration and plating specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm that the required polarizing key type matches the connector's acceptance capabilities. Cross-reference the manufacturer part number with authorized distributor catalogs to validate current availability status.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount interface is required for dual-edge cards. The 3.96 mm pitch and 34-position count define the electrical density. Verify that the application environment remains within the -40°C to +105°C operational range. Ensure the design accommodates the necessary polarizing key slots if signal isolation or mechanical locking is required.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts while maintaining consistent 3.96 mm spacing and 5 A current ratings. These connectors are engineered for robust panel mounting applications, providing reliable electrical connections through solder pin termination methods.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same series include models such as 305-030-520-278 and 305-040-520-278, which share identical pitch and mounting characteristics but differ in position count.
