306-039-520-103

Overview

The EDAC Inc. 306-039-520-103 is a standard card edge connector from the 306 series, designed for dual-edge female applications. It features 39 positions with a contact spacing of 3.96 mm (0.156 inches). The connector utilizes gold-plated copper alloy contacts and a thermoplastic housing. It supports a current rating of 5 A and an insulation resistance of 5 Gohms. Designed for panel mount installation at a vertical angle, it accommodates printed circuit boards with a nominal thickness of 1.57 mm.

Feature Summary

• Dual-edge female configuration for secure board insertion
• Gold-plated copper alloy contacts ensure reliable conductivity
• Thermoplastic insulator body provides structural stability
• Vertical panel mount design facilitates direct integration

Applications

• Panel-mounted electronic assemblies requiring dual-edge connectivity
• Industrial control systems utilizing standard card edge interfaces
• Communication equipment with vertical mounting constraints

Procurement Notes

Verify that the specific application requires a dual-edge connector configuration, as this component is not suitable for single-edge PCBs. Confirm that the target printed circuit board thickness aligns with the specified 1.57 mm nominal requirement to ensure proper mechanical engagement. Ensure the mounting environment supports the vertical panel mount style and that the 5 A current rating meets the electrical demands of the circuit. Cross-reference the 3.96 mm pitch with existing board layout specifications to guarantee compatibility.

Selection Notes

Select this component when a robust dual-edge interface is necessary for vertical panel installations. The 3.96 mm pitch offers a balance between density and spacing for standard industrial applications. The gold plating on copper alloy contacts is essential for environments where corrosion resistance and low contact resistance are critical. Consider the thermoplastic housing material for general-purpose durability. This connector is appropriate for designs where the PCB inserts into both sides of the connector body simultaneously.

Part Context

This part belongs to the EDAC 306 series, which specializes in card edge connectors with a 3.96 mm contact spacing. The series includes various configurations for different position counts and mounting styles. The 306-039-520-103 specifically addresses the need for a 39-position dual-edge solution. It complements other parts in the family by providing a standardized interface for high-reliability connections in panel-mount scenarios.

Replacement Considerations

Direct substitutes within the same series include the 306-033-520-102 for 33-position requirements. For higher position counts, the 306-039-520-108 shares similar electrical and mechanical characteristics. Verify that any replacement maintains the 3.96 mm pitch and dual-edge female configuration to ensure board compatibility.
