391-049-524-101

Edgeboard Connectors Overview

The EDAC Inc. 391-049-524-101 is a single-edge female card edge connector from the 391 series, designed for through-hole mounting. It features 49 positions with a 0.100-inch (2.54mm) pitch and two rows of contacts. The connector utilizes gold-plated copper alloy terminals with a 10.0µin thickness to ensure reliable signal transmission. Constructed with a black thermoplastic polyester body, it supports PCB thicknesses ranging from 0.054 to 0.070 inches. Operating within a temperature range of -40°C to 105°C, this component includes dual flanges for secure alignment and flat installation.

• Through-hole termination method

Edgeboard Connectors Applications

• Industrial control system circuit boards
• Communication equipment interface modules
• Medical device internal connectivity
• Consumer electronics expansion slots

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 49-position single-edge specification. Confirm that the ordering suffix corresponds to the correct contact finish and housing color. Ensure compatibility with the target PCB thickness range of 0.054 to 0.070 inches. Check for any specific environmental ratings if the application involves extreme temperatures beyond the standard operating range.

Edgeboard Connectors Selection Notes

Select this connector when a single-sided edge connection is required for compact board-to-board interfaces. The 0.100-inch pitch offers a balance between density and ease of manufacturing. Consider the dual-flange feature for applications requiring precise mechanical alignment without additional fasteners. Ensure the mating card meets the specified thickness tolerances for proper insertion force and electrical contact.

Edgeboard Connectors Part Context

This component belongs to the EDAC 391 series, which specializes in standard card edge connectors. The series is characterized by its robust construction and versatile positioning options. The 391 series is widely used in general-purpose electronic assemblies where reliable interconnection is critical. This specific model represents a mid-range position count suitable for moderate I/O requirements.

Edgeboard Connectors Replacement Considerations

Direct substitutes must maintain the 49-position single-edge format and 0.100-inch pitch. Verify that alternative parts support the same through-hole mounting style and dual-flange configuration. Ensure the replacement connector accommodates the identical PCB thickness range and operates within the same thermal limits.
