306-022-520-107

Overview

The EDAC Inc. 306-022-520-107 is a standard card edge connector from the 306 Series, designed for vertical panel mount applications. It features a dual female configuration with 44 positions arranged in two rows of 22 contacts each. The connector utilizes a 0.156-inch (3.96 mm) contact spacing and is constructed with a green thermoplastic insulator body. Contacts are made of copper alloy with gold plating to ensure reliable signal transmission. The unit accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). It operates within a temperature range of -40°C to +105°C and maintains an insulation resistance of 5 GOhms.

Feature Summary

• Dual-edge female contact design accommodating double-sided PCBs
• Gold-plated copper alloy contacts for enhanced conductivity
• Vertical panel mount installation style
• Compatible with 1.57 mm nominal thickness circuit boards

Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instrumentation panels
• Embedded computing modules with high-density I/O requirements

Procurement Notes

Verify that the specific part number matches the required 44-position dual-row configuration before procurement. Confirm that the receiving PCB meets the 1.57 mm thickness specification to ensure proper mechanical engagement. Check RoHS compliance documentation if environmental regulations apply to the assembly. Ensure storage conditions prevent contamination of the gold-plated contacts prior to installation.

Selection Notes

Select this component when a vertical, panel-mount interface is required for double-sided edge cards. The 3.96 mm pitch offers a balance between density and manufacturability compared to finer pitches. Consider the gold plating for environments where corrosion resistance is critical. Verify that the 5 A current rating per contact aligns with the electrical load requirements of the target application circuitry.

Part Context

This connector belongs to the EDAC 306 Series, which defines a family of standard card edge connectors characterized by 0.156-inch spacing. The series includes various position counts and mounting styles, but this specific model is optimized for dual-edge applications. It serves as a standardized interconnect solution within the broader category of board-to-board connectors used in modular electronic hardware designs.

Replacement Considerations

Direct substitutes must match the 44-position count, 3.96 mm pitch, and dual-edge female configuration. Verify that alternative components support the same 1.57 mm PCB thickness and vertical panel mount orientation. Cross-reference pinout definitions and mechanical footprint dimensions to ensure compatibility with existing tooling and PCB layouts.
