305-074-500-207

Edgeboard Connectors Overview

The EDAC Inc. 305-074-500-207 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 pitch and accommodates printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are constructed from copper alloy with gold plating, rated for 5 A current at an insulation resistance of 5 GOhms. Designed for vertical panel mounting, the unit operates within a temperature range of -40°C to +105°C and employs a thermoplastic insulator body.

Edgeboard Connectors Feature Summary

• Dual-row architecture providing 74 contact positions for high-density interconnect applications
• Gold-plated copper alloy contacts ensure reliable signal transmission and corrosion resistance
• Vertical panel mount design facilitates secure integration into chassis or enclosure structures

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connectivity
• Telecommunications equipment utilizing standard card edge form factors
• Test and measurement instrumentation needing reliable signal interfaces

Edgeboard Connectors Procurement Notes

Verify part authenticity through authorized EDAC channels or certified distributors. Confirm that the specific suffix matches the required pin count and termination style. Request official datasheets to validate electrical ratings against system requirements. Ensure compliance with RoHS directives if applicable to your manufacturing region. Cross-reference the Mouser number 587-305-074-500-207 for accurate catalog identification.

Edgeboard Connectors Selection Notes

Select this component when a 74-position dual-row interface is necessary for vertical panel installation. The 3.96 mm pitch suits applications where standard spacing is preferred over finer geometries. Verify that the target PCB thickness aligns with the 1.57 mm specification to ensure proper mechanical retention. Consider the 5 A current rating and operating temperature range to confirm suitability for the intended environmental conditions.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which specializes in standard card edge connectors. The series offers various position counts while maintaining consistent 3.96 mm pitch and dual-row configurations. These components are designed for general-purpose electronic applications requiring durable, low-profile connections between backplanes and daughter cards.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-072-500-207 and 305-070-500-207, which share identical mechanical and electrical specifications but differ in contact count. Ensure that any replacement maintains the 74-position requirement for functional compatibility.
