305-074-555-201

Edgeboard Connectors Overview

The EDAC Inc. 305-074-555-201 is a standard card edge connector receptacle featuring 74 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are constructed from copper alloy with gold plating, rated for 5 A current. The housing is made of green thermoplastic polyester, supporting operation between -40°C and +105°C. Designed for PCB mount installation with straight orientation, it employs solder termination.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design accommodates non-specified double-sided circuit boards
• Gold-plated copper alloy contacts ensure reliable signal transmission and corrosion resistance
• Low-profile insulator body facilitates compact panel or board mounting applications

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board interconnects
• Embedded computing modules utilizing standard thickness PCBs
• Telecommunications equipment interfaces

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact row spacing and mechanical tolerances. Ensure compatibility with the target PCB thickness of 1.57 mm before integration. Confirm RoHS compliance status through the manufacturer's latest environmental declarations. Cross-reference the series guide to validate pin count and termination type requirements for the specific assembly.

Edgeboard Connectors Selection Notes

Select this component when a 74-position dual-row interface is required for 1.57 mm thick boards. The 3.96 mm pitch suits general-purpose digital and power distribution needs. Verify that the straight mounting style aligns with the enclosure constraints. Consider the 5 A rating per contact for load calculations. Ensure the gold plating meets the environmental exposure requirements of the deployment site.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series of standard card edge connectors. The series offers various position counts and mounting styles for diverse electronic assemblies. The 305 line is characterized by its durable thermoplastic construction and standardized dimensions, ensuring interchangeability within compatible system designs.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series ordering guide for direct substitutes with different pin counts or mounting orientations. Verify mechanical footprint compatibility before considering alternative manufacturers.
