305-074-520-258

Edgeboard Connectors Overview

The EDAC Inc. 305-074-520-258 is a standard card edge connector featuring 74 positions arranged in a dual row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and is designed for panel mount installation at a vertical angle. The contacts are constructed from copper alloy with gold plating, supporting a continuous current rating of 5 A. The housing is made of green thermoplastic material, suitable for operating temperatures ranging from -40°C to +105°C. This component employs solder pin termination and accepts between-contact and in-contact polarizing keys.

Edgeboard Connectors Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm compatibility with required polarizing keys and panel thickness specifications. Ensure that the thermal environment remains within the stated operational range of -40°C to +105°C during system integration. Cross-reference the gold plating requirements with application-specific corrosion resistance needs before final procurement authorization.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row interface with a 3.96 mm pitch is required for panel-mounted applications. The 5 A current rating and gold-plated contacts make it suitable for environments demanding stable conductivity. Consider the vertical orientation and thermoplastic housing properties for mechanical stability and thermal management in enclosed assemblies.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and configurations, all sharing common design principles such as gold-plated contacts and compatible polarizing key systems. The 305-074-520-258 specifically provides a 74-position solution within this established family of reliable interconnect solutions.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and row count but different position numbers, such as 305-048-520-258 or 305-054-556-278, provided the physical footprint and terminal count match the design requirements.
