306-028-500-104

Overview

The EDAC Inc. 306-028-500-104 is a dual-edge female card edge connector from the 306 series, designed for panel mount applications. It features 56 positions arranged in two rows with a 0.156-inch (3.96mm) contact spacing. The connector utilizes copper alloy contacts with gold plating and a thermoplastic polyester insulator. It accepts printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches (1.37mm to 1.78mm). The unit operates within a temperature range of -40°C to 105°C and includes flange features for flush mounting.

Feature Summary

• Dual-edge female configuration with 56 total positions
• Gold-plated copper alloy contacts for reliable signal transmission
• Thermoplastic polyester insulator body for durability
• Panel mount design with flush mounting flanges

Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instrumentation needing high-reliability interconnects
• Automotive electronics modules compatible with specified board thicknesses

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required board thickness and mounting style. Confirm that the gold plating specification meets the environmental requirements for the intended application. Check for any recent product change notifications or obsolescence notices directly from EDAC Inc. before finalizing procurement plans.

Selection Notes

Select this component when a dual-edge female connector with 0.156-inch spacing is required for panel-mounted installations. Ensure the target printed circuit board falls within the specified thickness range of 0.054 to 0.070 inches. Consider the operating temperature range and material composition if the environment involves chemical exposure or extreme thermal conditions.

Part Context

This part belongs to the EDAC 306 series of card edge connectors, which are characterized by their low-profile insulator bodies and acceptance of nominal 0.062-inch PCB thickness. The series offers various position counts and mounting options, providing flexibility for different electronic assembly needs while maintaining consistent electrical performance standards across the family.

Replacement Considerations

Consult the EDAC 306 Series Ordering Guide for direct substitutes with differing pin counts or mounting variations. Verify mechanical fit and electrical specifications before replacing with components from other manufacturers. Cross-reference with distributor databases for availability of equivalent parts if supply chain constraints exist.
