306-011-420-178

Edgeboard Connectors Overview

The EDAC Inc. model 306-011-420-178 is a standard card edge connector receptacle featuring 22 positions in a dual female configuration. It utilizes a 0.156-inch (3.96 mm) contact spacing and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The component employs gold-plated copper alloy contacts with a solder termination type for secure electrical connections. Designed for through-hole mounting at a straight angle, the insulator body is constructed from thermoplastic polyester to ensure structural integrity.

Edgeboard Connectors Feature Summary

• Dual female contact configuration designed for reliable signal transmission across multiple channels
• Gold-plated copper alloy terminals provide corrosion resistance and stable conductivity
• Low profile insulator body accommodates space-constrained electronic assemblies
• Through-hole solder termination ensures robust mechanical attachment to the substrate

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Medical device internal circuitry
• Consumer electronics mainboard interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact pin count, plating thickness, and board thickness compatibility. Ensure the procurement channel provides authentic components with traceable documentation. Cross-reference the part number with official EDAC databases to confirm availability status and any recent design revisions that may impact physical dimensions or material specifications.

Edgeboard Connectors Selection Notes

Select this component when a dual-sided connection is required for a 1.57 mm thick PCB with a 3.96 mm pitch. Confirm that the application environment does not exceed the thermal limits of the thermoplastic polyester housing. Validate that the through-hole mounting style aligns with the assembly process capabilities and that the straight orientation fits within the designated chassis clearance constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 306 series of card edge connectors, which are engineered for high-density interconnect applications. The series offers various position counts and mounting options to support diverse electronic design requirements. As a standard receptacle, it interfaces directly with edge-mounted circuit boards, providing a stable mechanical and electrical link in modular system architectures.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC cross-reference guide for verified substitute part numbers. Ensure any alternative maintains identical 22-position count, 3.96 mm spacing, and 1.57 mm board thickness acceptance. Verify that the replacement matches the dual female contact configuration and through-hole mounting requirements.
