306-020-400-178

Edgeboard Connectors Overview

The EDAC Inc. 306-020-400-178 is a standard card edge connector from the 306 series, designed for dual-edge female connections. It features 40 positions arranged in two rows with a 0.156-inch (3.96mm) pitch. The connector utilizes tin-plated contacts and a green thermoplastic polyester housing. It supports PCB thicknesses between 1.37mm and 1.78mm and operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for non-specified card types
• Tin-plated contact finish for reliable signal transmission
• Thermoplastic polyester insulation material for durability

Edgeboard Connectors Applications

• Industrial control systems requiring robust edge connections
• Telecommunications equipment interface modules
• General-purpose electronic assemblies needing dual-row connectivity

Edgeboard Connectors Procurement Notes

Verify that the specific application requires a tin-plated finish rather than gold, as this model differs from other variants in the 306 series. Confirm compatibility with the target PCB thickness range of 1.37mm to 1.78mm. Ensure the design accommodates the 0.156-inch pitch spacing. Check regional availability as distribution status may vary by location.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 3.96mm pitch is required. The tin plating offers a cost-effective solution compared to gold-plated alternatives. Consider the operating temperature range of -40°C to 105°C for environmental suitability. Verify that the 40-position count meets the circuit requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 series of standard card edge connectors. The series includes various position counts and plating options. This specific model distinguishes itself with a 40-position layout and tin plating, differing from similar parts like the 306-007-521-158 which uses gold plating.

Edgeboard Connectors Replacement Considerations

The 306-020-400-158 is a direct substitute offering identical mechanical specifications but with gold-plated contacts instead of tin. Other models in the 306 series may serve as alternatives if position count or pitch differences are acceptable.
