305-074-520-278

Edgeboard Connectors Overview

The EDAC Inc. model 305-074-520-278 is a standard card edge connector header designed for panel mounting applications. It features a dual-row configuration with 74 positions and a contact spacing of 3.96 mm (0.156 inches). The unit utilizes gold-plated copper alloy contacts with solder pin termination to ensure reliable electrical connections. Designed for vertical installation, the connector accommodates printed circuit boards with a nominal thickness of 1.57 mm. The housing is constructed from green thermoplastic material, providing structural integrity and insulation.

Edgeboard Connectors Procurement Notes

Verify the specific part number against official EDAC documentation to confirm compatibility with your PCB stack-up and mechanical requirements. Ensure that the ordering suffix matches the desired contact plating and housing color specifications. Cross-reference the manufacturer's latest datasheet to validate current RoHS compliance status and environmental operating temperature ranges before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-density connection is required for double-sided edge cards. The 3.96 mm pitch allows for robust trace routing on the mating board. Consider the 1.57 mm board thickness tolerance to ensure proper insertion depth. Verify that the panel mounting style aligns with the enclosure design constraints and that the vertical orientation fits within the available spatial envelope.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which defines a family of standard card edge connectors characterized by a 0.156-inch contact spacing. The series offers various position counts and row configurations to support diverse interface needs. The 305-074 variant specifically addresses applications requiring a higher pin count while maintaining the standardized mechanical footprint and electrical performance typical of the broader product line.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series headers with matching 74-position counts and 3.96 mm pitch. Verify that alternative parts maintain identical panel mounting styles and vertical orientations. Ensure that any replacement maintains the same dual-row female contact configuration and compatible board thickness specifications.
