306-028-420-168

Overview

The EDAC Inc. part number 306-028-420-168 is a dual-edge card edge connector designed for high-density interconnect applications. It features 56 positions arranged in a double-row configuration with a contact spacing of 0.156 inches (3.96 mm). The connector utilizes female contacts with a tin plating finish to ensure reliable signal transmission. Constructed with a green insulator, it supports PCB thicknesses ranging from 0.051 to 0.071 inches. The component operates within a temperature range of -55°C to +85°C and meets RoHS3 standards for environmental compliance.

Feature Summary

• Dual-edge female contact design for secure board insertion
• Tin-plated terminals for corrosion resistance and conductivity
• Green insulator housing with flush mounting capability
• Compliant with RoHS3 environmental regulations

Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Medical device circuit boards
• Energy management hardware interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm terminal type and plating specifications. Ensure the target PCB thickness falls within the supported range of 0.051 to 0.071 inches for proper mechanical engagement. Confirm that the application environment remains within the specified operating temperature limits of -55°C to +85°C. Cross-reference the pin count and row configuration with the schematic requirements before finalizing procurement orders.

Selection Notes

Select this connector when a dual-edge interface with 0.156-inch spacing is required for robust signal integrity. The tin-plated contacts offer a cost-effective solution compared to gold plating while maintaining durability. Consider the green insulator color for visual identification during assembly processes. Evaluate the flush mount style against available panel clearance constraints. This series provides a standardized footprint compatible with various industrial form factors.

Part Context

This component belongs to the EDAC 306 Series, which specializes in standard card edge connectors. The series offers various position counts and spacing options to accommodate diverse board layouts.
