305-050-520-201

Edgeboard Connectors Overview

The EDAC Inc. 305-050-520-201 is a standard card edge connector receptacle featuring 50 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and is designed for PCB mounting at a straight angle. The contacts are gold-plated copper alloy, rated for 5 A current, with solder termination. The housing is thermoplastic, supporting a board thickness of 1.57 mm. Operating temperature ranges from -40°C to +105°C, with an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-edge female contact interface for secure card insertion
• Gold-plated copper alloy contacts ensure reliable conductivity
• Thermoplastic housing provides structural stability and insulation

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Automotive electronic modules
• Medical device circuit boards

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer datasheet to confirm exact plating thickness and material specifications. Ensure compatibility with the target printed circuit board thickness of 1.57 mm before integration. Confirm RoHS compliance status through official documentation rather than distributor summaries.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 50-position connection is required for non-specified dual-edge cards. The straight mounting style suits applications where the connector aligns parallel to the board edge. Verify that the 5 A current rating meets the circuit requirements and that the operating temperature range covers the environmental conditions.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and row configurations. The 305-050-520-201 specifically addresses the need for medium-density connections in space-constrained electronic assemblies requiring durable solder termination.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and row count but different position numbers, such as 305-040-520-201 or 305-060-520-201, provided the mechanical footprint allows.
