306-008-521-178

Edgeboard Connectors Overview

The EDAC Inc. model 306-008-521-178 is a standard card edge connector receptacle from the 306 series. It features an 8-position, single-row configuration with a 3.96 mm (0.156 inch) contact spacing. Designed for through-hole mounting in a straight orientation, it accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are constructed from copper alloy and feature gold plating to ensure reliable signal transmission. The insulator body is made of thermoplastic polyester, providing durability and electrical insulation.

Edgeboard Connectors Feature Summary

• Single row receptacle design compatible with 0.062 inch thick PCBs
• Gold-plated copper alloy contacts for enhanced conductivity
• Thermoplastic polyester insulator body for structural stability

Edgeboard Connectors Applications

• General purpose electronic interconnect systems
• Industrial control panel wiring
• Consumer electronics assembly

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm pin count and row configuration. Ensure compatibility with the target PCB thickness of 0.062 inches. Confirm that the through-hole termination style matches the assembly process requirements. Cross-reference the RoHS status if environmental compliance is mandatory for the end application.

Edgeboard Connectors Selection Notes

Select this component when a single-row, low-profile connection is required for standard thickness boards. The 3.96 mm pitch offers robust mechanical alignment. Gold plating is suitable for applications requiring corrosion resistance and stable contact resistance. Consider the straight mounting angle for board-to-board or backplane interfaces where space constraints favor a non-angled profile.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 series of standard card edge connectors. The series is characterized by its .156 inch contact spacing and acceptance of .062 inch nominal PCB thickness. The 306 series provides a range of position counts and mounting styles, serving as a versatile solution for various interconnect needs in commercial and industrial electronics.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include EDAC part numbers such as 306-008-521-102 and 306-008-521-103, which share identical mechanical dimensions and contact specifications. Verify that any alternative part maintains the single-row, 8-position configuration and through-hole termination type.
