306-031-421-168

Overview

The EDAC Inc. 306-031-421-168 is a dual female edgeboard connector designed for panel mount and through-hole termination. It features 62 positions with a 0.156-inch (3.96mm) contact spacing across two rows of 31 contacts each. The connector utilizes tin-plated copper alloy cantilever contacts and a green thermoplastic polyester insulator. It accommodates card thicknesses between 0.054 and 0.070 inches (1.37mm to 1.78mm). Operating temperatures range from -40°C to 105°C, and it complies with RoHS3 standards.

Feature Summary

• Dual female configuration with cantilever spring contacts for reliable board insertion
• Panel mount installation with flush flange and top opening design
• Tin surface finish on copper alloy contacts for corrosion resistance
• Green thermoplastic polyester insulator body for thermal stability

Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Medical device circuit board connections
• Energy management system interfaces

Procurement Notes

Verify the specific pin count and row configuration against the target PCB layout before ordering. Confirm that the required card thickness falls within the specified 0.054 to 0.070 inch range to ensure proper mechanical retention. Check for RoHS3 compliance requirements if operating in regulated environments. Ensure the mounting hole diameter matches the 0.156 inch flange specification for secure panel attachment.

Selection Notes

Select this component when a high-density dual-row connection is required with a wide 0.156 inch pitch. It is suitable for applications needing robust panel mounting rather than board-only retention. Consider the tin plating if gold plating is not strictly necessary for low-contact-resistance signal integrity. Evaluate the operating temperature range against environmental conditions to confirm suitability for industrial or outdoor deployments.

Part Context

This part belongs to the EDAC 306 series of edgeboard connectors, which are characterized by their large contact spacing and durable construction. The series offers various position counts and mounting options to support diverse electronic assembly needs. The 306 series is widely used in heavy-duty applications requiring reliable mechanical and electrical connections over extended periods.

Replacement Considerations

Direct substitutes include other EDAC 306 series parts with matching pin counts and spacing, such as the 306-031-421-104 for similar dual female configurations. Verify compatibility with existing PCB footprints and mounting hardware before switching to alternative manufacturers.
