306-028-420-103

Overview

The EDAC Inc. 306-028-420-103 is a standard card edge connector receptacle designed for vertical panel mount applications. It features a dual-edge configuration with 56 positions arranged in two rows, providing a total of 56 contact points. The connector utilizes a 0.156-inch (3.96 mm) pitch and is compatible with PCBs having a thickness of 0.062 inches (1.57 mm). The contacts are constructed from copper alloy and feature tin plating to ensure reliable signal transmission. Termination is achieved via solder eyelets, securing the component to the board.

Feature Summary

• Dual-edge female connector design accommodating double-sided circuit boards
• Vertical orientation suitable for panel mounting installations
• Tin-plated copper alloy contacts for corrosion resistance
• Solder eyelet termination method for secure board attachment

Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation
• General-purpose electronic assemblies using double-sided PCBs

Procurement Notes

Verify that the target application utilizes double-sided printed circuit boards, as this connector requires mating edges on both sides of the substrate. Confirm that the PCB fabrication tolerance allows for the specified 0.062-inch thickness to ensure proper contact engagement. Ensure the manufacturing environment does not require gold-plated contacts, as this specific part number specifies tin plating, which may have different wear characteristics compared to gold finishes.

Selection Notes

Select this component when a high-density connection is required within a limited panel space, utilizing the 0.156-inch pitch. Consider the tin plating specification if cost efficiency is prioritized over extended cycle life in harsh environments. Verify that the mechanical constraints of the enclosure allow for the vertical profile and that the solder eyelet termination aligns with the available assembly processes for the production line.

Part Context

This part belongs to the EDAC 306 series, which focuses on standard card edge connectors. The series offers various position counts and configurations to support diverse connectivity needs. The 306-028-420-103 specifically addresses applications needing 56 connections with a standardized pitch, fitting into the broader portfolio of EDAC's interconnection solutions for industrial and commercial electronics.

Replacement Considerations

Compatible substitutes include other EDAC 306 series parts with matching 56-position dual-edge configurations and 0.156-inch pitch. When evaluating alternatives, ensure the replacement maintains the same vertical panel mount style and solder eyelet termination type. Verify that any cross-brand equivalent matches the critical dimensional parameters and material specifications for direct interchangeability.
