305-074-520-558

Edgeboard Connectors Overview

The EDAC Inc. 305-074-520-558 is a standard card edge connector featuring 74 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a 3.56 mm row spacing. The component is designed to accept printed circuit boards with a nominal thickness of 1.57 mm. Electrical specifications include a current rating of 5 A and an insulation resistance of 5 GOhms. The contacts are gold-plated copper alloy, while the housing is constructed from thermoplastic material. It supports a vertical panel mount style and operates within a temperature range of -40 C to +105 C.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design accommodating 74 positions for reliable signal transmission.
• Low-profile insulator body optimized for space-constrained panel mounting applications.
• Gold-plated copper alloy contacts ensure durable conductivity and corrosion resistance.

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connectivity
• Telecommunications equipment utilizing standard card edge interfaces
• Automotive electronics modules needing high-temperature stability

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact plating thickness, housing color, and termination type variations. Ensure compatibility with the target PCB thickness of 1.57 mm before integration. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability status and regional distribution restrictions. Confirm RoHS compliance details through the latest datasheet revision.

Edgeboard Connectors Selection Notes

Select this model when a dual-row interface with 74 positions and 3.96 mm pitch is required for vertical panel installation. The 5 A current rating and wide operating temperature range make it suitable for demanding environments. Consider the low-profile housing dimensions if height constraints exist within the enclosure. Verify that the solder pin termination method aligns with the assembly process capabilities.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and row configurations to support diverse electronic interconnection needs. The 305 series is characterized by its thermoplastic housing and gold-plated contacts, providing a balance of performance and cost-effectiveness for general-purpose industrial and commercial applications.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and position counts but different suffixes indicating variant features. Verify mechanical fit and electrical ratings before swapping. No alternative manufacturers' direct equivalents are confirmed in public documentation without custom engineering.
