306-010-420-178

Edgeboard Connectors Overview

The EDAC Inc. 306-010-420-178 is a standard card edge connector from the 306 series, designed for dual-edge board applications. It features 20 positions with a 0.156-inch (3.96 mm) pitch. The connector utilizes a female contact type with tin plating and copper alloy contacts. It supports panel mount installation in a vertical orientation and accepts board thicknesses ranging from 0.054 to 0.070 inches (1.37 to 1.78 mm). The housing is constructed from green thermoplastic polyester.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design for secure mating with double-sided circuit boards
• Vertical panel mount configuration with flange features for stable alignment
• Copper alloy contacts with tin plating for reliable signal transmission

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment with high-density connection needs
• Test and measurement instrumentation modules

Edgeboard Connectors 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 tin-plated contact finish meets the environmental and conductivity requirements of the target application. Cross-reference the 20-position count and 3.96 mm pitch with the PCB layout specifications before procurement to prevent mechanical mismatch.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 3.96 mm pitch is required for vertical panel mounting. Ensure the application environment falls within the specified operating temperature range and that the thermoplastic polyester housing provides adequate insulation resistance. Verify that the tin plating is suitable for the intended mating cycles and corrosion conditions compared to gold-plated alternatives.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and mounting styles to accommodate different board densities. The 306-010-420-178 specifically addresses applications needing dual-edge connectivity with a standardized pitch, providing a balance between performance and cost-effectiveness for general-purpose interconnect solutions.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 306 Series Ordering Guide for direct substitutes with differing position counts or contact finishes. Verify mechanical footprint compatibility if considering connectors from other manufacturers, as panel mount dimensions may vary despite identical electrical parameters.
