305-078-520-258

Edgeboard Connectors Overview

The EDAC Inc. part number 305-078-520-258 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features a dual female configuration with 78 positions and a pitch of 0.156 inches (3.96 mm). The contacts are gold-plated copper alloy, supporting a current rating of 5 A. The housing is constructed from thermoplastic material, rated for operation between -40°C and +105°C, with an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual row female contact configuration for high-density signal routing
• Gold-plated copper alloy contacts ensure reliable conductivity and corrosion resistance
• Thermoplastic housing provides structural integrity and electrical insulation
• Vertical panel mount design facilitates secure board-to-panel integration

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment with high pin count requirements
• Test and measurement instrumentation panels
• Automotive electronics assemblies

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required contact plating and housing color specifications. Confirm compatibility with the target PCB thickness of 1.57 mm to ensure proper mechanical engagement. Check regional availability as distribution may be restricted in certain areas. Ensure compliance with RoHS directives if applicable to the end product.

Edgeboard Connectors Selection Notes

Select this component when a 78-position dual-row interface is necessary for vertical panel mounting. The 3.96 mm pitch accommodates larger traces compared to finer pitches. Consider the 5 A current rating for power or high-current signal lines. Verify that the right-angle or straight variant aligns with the mechanical constraints of the enclosure design.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and pitch options to suit different density requirements. The 305 series is characterized by its durable thermoplastic housing and reliable solder pin termination, making it suitable for demanding industrial environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with matching 78 positions and 3.96 mm pitch, such as 305-078-520-504 or 305-078-520-278, provided they meet the same electrical and mechanical specifications.
