305-074-556-201

Edgeboard Connectors Overview

The EDAC Inc. 305-074-556-201 is a standard card edge connector from the 305 series, designed for dual-edge female applications. It features 74 positions with a 0.156-inch (3.96mm) pitch and accepts board thicknesses between 0.054 and 0.070 inches. The connector utilizes gold-plated copper alloy contacts with a half-bead termination style and solder pin end-type. Rated for 5A current, it operates within a temperature range of -40°C to +105°C and includes flange features for panel mounting.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for non-specified card edge boards
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Solder pin termination provides secure PCB attachment
• Flanged design supports stable panel installation

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Automotive electronic modules
• Test and measurement instrumentation

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact contact plating thickness and material specifications. Ensure that the selected variant matches the required board thickness tolerance and current rating for the target application environment. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and compliance with relevant environmental standards such as RoHS.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-edge connection is required for rigid printed circuit boards. The 3.96mm pitch accommodates standard board layouts while the 5A rating supports moderate power distribution. Consider the vertical panel mount style if space constraints require a perpendicular interface orientation relative to the mating card edge.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers a range of standard card edge solutions. The series is characterized by its versatility in position counts and mounting styles, catering to various industrial and commercial electronics needs. The 305-074-556-201 specifically addresses the need for a 74-position interface with durable metallic contacts.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for compatible alternatives with differing position counts or mounting orientations. Verify mechanical compatibility with existing panel cutouts and PCB footprints before substituting with other series members.
