305-078-521-568

Edgeboard Connectors Overview

The EDAC Inc. 305-078-521-568 is a standard card edge connector from the 305 series, featuring 78 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 connector employs gold-plated copper alloy contacts with a half-waveform termination type for reliable signal transmission. Designed for panel mounting at a vertical angle, it supports a continuous current rating of 5 A and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female interface designed for non-specified board types
• Gold-plated copper alloy contacts ensure durable electrical connection
• Vertical panel mount style with low-profile insulator body
• Accepts polarizing keys for secure board positioning

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Medical device circuit board integration
• Consumer electronics modular assemblies

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's ordering guide to confirm exact plating thickness and flange characteristics. Ensure the target PCB thickness aligns with the 1.57 mm nominal requirement. Confirm RoHS compliance status if restricted materials are prohibited in your assembly process. Cross-reference the lead time with the distributor as availability may vary by region.

Edgeboard Connectors Selection Notes

Select this component when a high-density 78-position connection is required in a vertical panel-mount configuration. The 3.96 mm pitch offers a balance between density and manufacturability. Consider the 5 A current rating for power distribution needs. Verify that the housing material and operating temperature range meet the environmental demands of the final application.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in industrial and commercial applications. The series provides various position counts and mounting styles. The 305-078 variant specifically addresses mid-range density requirements, offering robust mechanical stability through its panel-mount design while maintaining electrical reliability through gold-plated contacts.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with different position counts or flange options. Verify compatibility with existing PCB layouts before switching to alternative part numbers within the same family.
