305-076-556-508

Edgeboard Connectors Overview

The EDAC Inc. 305-076-556-508 is a standard card edge connector from the 305 series, designed for panel mount applications. It features a dual-edge configuration with 76 positions and a pitch of 3.96 mm (0.156 inches). The connector supports a board thickness of 1.57 mm and utilizes gold-plated copper alloy contacts to ensure reliable signal transmission. Rated for 5 A current, it employs a solder pin termination method for secure PCB attachment. The housing is constructed from thermoplastic material, providing durability in demanding environments.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB edge card dimensions, particularly the 1.57 mm thickness constraint. Cross-reference the 76-position count with schematic requirements to prevent mismatched assembly errors during integration.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection is required for high-pin-count applications. The 3.96 mm pitch accommodates standard board layouts while maintaining electrical isolation. Consider the 5 A rating for power distribution needs within the system architecture. Verify that the vertical panel mount style aligns with the mechanical enclosure design constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic designs. The series offers various position counts and termination styles to suit different density requirements. As a header type connector, it interfaces directly with mating edge cards, providing a stable mechanical and electrical link in complex assemblies.

Edgeboard Connectors Replacement Considerations

Consult official EDAC substitution guides for compatible alternatives. Verify that any substitute maintains the 3.96 mm pitch and 76-position count. Ensure the replacement part supports the same 1.57 mm board thickness and panel mount configuration to preserve mechanical fit.
