306-009-400-178

Edgeboard Connectors Overview

The EDAC Inc. model 306-009-400-178 is a standard card edge connector receptacle featuring 18 positions with a 3.96 mm (0.156 inch) contact spacing. Designed for dual-edge insertion, it accommodates printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The component utilizes tin-plated copper alloy contacts and a green thermoplastic insulator body. It employs a through-hole solder termination method and is configured for straight mounting orientation.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design for secure board insertion
• Low-profile insulator body construction
• Single centerline row configuration
• Through-hole solder termination for reliable PCB attachment

Edgeboard Connectors Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Consumer electronic module interfaces
• Medical device internal circuitry connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm plating type and material specifications, as variations exist within the series. Confirm that the target application supports the 1.57 mm board thickness requirement. Ensure compatibility with the 3.96 mm pitch before finalizing procurement orders. Cross-reference the manufacturer datasheet for precise mechanical dimensions.

Edgeboard Connectors Selection Notes

Select this component when a single-row, dual-edge connector is required for 1.57 mm thick boards. The 3.96 mm pitch suits applications needing fewer pins in a compact footprint. Tin plating offers cost-effective performance for general-purpose environments. Consider gold-plated variants if higher corrosion resistance or lower contact resistance is necessary for the specific operational environment.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 series of standard card edge connectors. The series provides various position counts and termination options. The 306 series is designed for general-purpose electronic interconnections, offering a balance of reliability and ease of assembly through standard through-hole mounting techniques.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 306 series parts with matching 18-position counts and 3.96 mm pitch. Verify that alternative components support dual-edge insertion and identical 1.57 mm board thickness constraints. Check for compatible mounting styles and termination types to ensure mechanical fit.
