306-011-421-178

Edgeboard Connectors Overview

The EDAC Inc. 306-011-421-178 is a dual-edge female card edge connector from the 306 Series, designed for non-specified board applications. It features 22 positions with a 0.156-inch (3.96mm) pitch and cantilever contacts. The unit utilizes green thermoplastic polyester insulation and gold-plated copper alloy terminals. Rated for 5A current at 105°C, it supports PCB thicknesses of 1.57mm via solder pin termination.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with cantilever contact type for reliable board insertion
• Gold-plated copper alloy terminals ensure durable electrical connectivity
• Thermoplastic polyester housing provides structural integrity and thermal resistance

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Consumer electronics module connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm plating thickness and material variants. Ensure the ordering part number matches the required contact count and pitch specifications exactly. Cross-reference the RoHS compliance status with the latest official documentation before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female interface with a 3.96mm pitch is required. Confirm that the target PCB thickness aligns with the 1.57mm specification. Evaluate the 5A current rating and 105°C operating temperature range against the application's thermal and electrical demands to ensure long-term reliability.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 306 Series, which specializes in standard card edge connectors. The series offers various position counts and housing colors, including green options. It is engineered for through-hole soldering and vertical panel mounting, providing a robust solution for high-density electronic assemblies requiring stable signal transmission.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include EDAC part numbers sharing the 306 prefix and identical 22-position dual-edge specifications. Verify that alternative candidates maintain the same 0.156-inch pitch and cantilever contact design to ensure mechanical compatibility.
