305-078-500-201

Edgeboard Connectors Overview

The EDAC Inc. 305-078-500-201 is a standard card edge connector from the 305 Series, designed for reliable signal transmission in electronic assemblies. This receptacle features 78 positions arranged in a dual-row configuration with a 3.96 mm (0.156 inch) pitch. It utilizes gold-plated copper alloy contacts and a green thermoplastic housing to ensure durability and corrosion resistance. The component supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C. Designed for panel mounting, it accommodates board thicknesses between 1.37 mm and 1.78 mm, providing secure connections for non-specified dual-edge cards.

Edgeboard Connectors Feature Summary

• Dual-row receptacle design with 78 positions for high-density interconnect applications
• Gold-plated copper alloy contacts ensure low contact resistance and long-term reliability
• Green thermoplastic housing provides mechanical stability and environmental protection
• Panel mount installation style with solder pin termination for secure PCB integration

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing modular board architectures
• Test and measurement instruments needing reliable signal pathways
• Automotive electronics modules demanding stable connectivity

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 78-position dual-row configuration before procurement. Confirm that the operating environment falls within the specified -40°C to +105°C temperature range. Ensure that the mating card thickness aligns with the 1.37 mm to 1.78 mm acceptance window. Check for RoHS compliance requirements if applicable to your assembly standards. Validate that the panel mounting style fits the mechanical constraints of the final enclosure design.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count interface is necessary for dual-edge card applications. The 3.96 mm pitch offers a balance between density and manufacturability. Consider the gold plating for environments where oxidation resistance is critical. The thermoplastic housing material provides good insulation properties suitable for general-purpose industrial use. Evaluate the panel mount requirement against free-hanging alternatives if space constraints differ.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 Series, which includes various configurations of card edge connectors. The series is characterized by its standardized dimensions and reliable performance in demanding environments. Similar parts in the series may vary in position count, such as 48 or 86 positions, but share common pitch and mounting characteristics. The 305-078-500-201 specifically addresses needs for higher channel counts within this established product line.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include other 78-position variants like the 355-078-500-201, which shares identical electrical and mechanical specifications. Cross-referencing with other manufacturers requires verifying pitch, row count, and housing dimensions. Ensure that any replacement maintains the same current rating and temperature tolerance. Compatibility with existing tooling and mating cards must be confirmed before substitution.
