391-036-520-108

Edgeboard Connectors Overview

The EDAC Inc. 391-036-520-108 is a standard card edge connector from the 391 series, designed for signal communication and power connection between motherboards, daughterboards, and extenders. It features a dual female configuration with 36 positions arranged in two rows. The connector utilizes a 0.100-inch (2.54mm) contact spacing and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). Constructed with copper alloy contacts featuring gold plating and a black thermoplastic polyester insulator, it supports through-hole termination via solder eyelets. This component is engineered to provide reliable interconnection in various electronic applications requiring robust mechanical stability and electrical performance.

Edgeboard Connectors Feature Summary

• Gold-plated copper alloy contacts ensure reliable conductivity
• Thermoplastic polyester insulator body provides structural integrity
• Through-hole solder eyelet termination facilitates PCB mounting

Edgeboard Connectors Applications

• Motherboard to daughterboard interconnections
• System extender module connections
• General-purpose signal and power routing in industrial electronics

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact pin count, row spacing, and termination style. Ensure compatibility with the target PCB thickness of 0.062 inches. Confirm that the gold plating specification meets the required environmental and durability standards for the intended application environment before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this connector when a low-profile, high-reliability interface is required for 36-position dual-row applications. The 0.100-inch pitch suits standard board layouts, while the through-hole solder eyelet design offers superior mechanical retention compared to surface mount alternatives. Consider the operating temperature range and material composition to ensure suitability for the specific thermal and chemical conditions of the assembly.

Edgeboard Connectors Part Context

This component belongs to the EDAC 391 series, which specializes in quality-engineered solutions for connecting motherboards, daughterboards, and extenders. The series is characterized by its standardized dimensions and robust construction, making it a common choice in industrial and commercial electronic systems where stable signal transmission and power delivery are critical requirements for long-term operation.

Edgeboard Connectors Replacement Considerations

Cross-reference compatible parts within the EDAC 391 series or other manufacturers' standard card edge connectors. Verify that substitute components match the 36-position count, 0.100-inch pitch, and 0.062-inch board thickness specifications. Ensure identical termination methods and contact materials to maintain system reliability and mechanical fit without redesigning the host PCB layout.
