305-074-556-258

Edgeboard Connectors Overview

The EDAC Inc. 305-074-556-258 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 74 positions arranged in a dual-row configuration with a pitch of 3.96 mm (0.156 inches). The connector accepts PCBs with a nominal thickness of 1.57 mm and utilizes gold-plated copper alloy contacts rated for 5 A current. It employs solder pin termination and includes an insulating thermoplastic housing.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for secure board insertion
• Gold-plated copper alloy contacts ensure reliable conductivity
• Thermoplastic insulator housing provides structural integrity
• Vertical panel mount design facilitates fixed installation

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Computing hardware peripheral interfaces

Edgeboard Connectors Procurement Notes

Verify the specific suffix against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm that the vertical panel mount style aligns with the mechanical enclosure requirements. Cross-reference the 74-position count to prevent mismatched slot widths.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 3.96 mm spacing is required for high-density connections. The 5 A rating supports moderate power distribution needs. Verify that the vertical mounting angle fits within the available chassis depth. Consider the solder pin termination method for standard wave or reflow soldering processes compatible with the specified contact geometry.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts while maintaining consistent 3.96 mm pitch and 1.57 mm PCB thickness acceptance. The 305-074 variant specifically provides 74 contact points, distinguishing it from lower-count models like the 305-054 or higher-count alternatives within the same family.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical 74-position dual-row configurations, such as 305-074-556-278, provided the suffix variations do not alter the functional interface. Verify that any replacement maintains the 3.96 mm pitch and 1.57 mm board thickness tolerance.
