306-028-421-103

Overview

The EDAC Inc. 306-028-421-103 is a dual female edgeboard connector designed for panel mount and through-hole termination. It features 56 positions with a 0.156-inch (3.96mm) contact spacing arranged in a single centerline row. The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). Constructed with copper alloy contacts finished in tin plating, the insulator body is made of thermoplastic polyester. It operates within a temperature range of -40°C to 105°C and complies with RoHS3 standards.

Feature Summary

• Accepts standard .062 inch nominal thickness PCBs
• Low profile insulator body design
• Single centerline row configuration

Applications

• Industrial control systems
• Communication equipment
• Medical devices
• Energy infrastructure components

Procurement Notes

Verify the specific pin count and spacing against the original design specifications before procurement. Confirm that the supplier provides documentation confirming RoHS3 compliance and REACH status. Ensure the ordering suffix matches the required contact finish and insulation material characteristics defined by the manufacturer's current product line data.

Selection Notes

Select this component when a low-profile dual female connector is required for .062 inch thick boards. The 0.156 inch spacing accommodates standard board layouts. Verify that the operating temperature range meets system requirements. Ensure the panel mount installation type aligns with the mechanical enclosure design constraints.

Part Context

This part belongs to the EDAC 306 series of card edge connectors. The series offers various position counts and spacing options. The 306-043-421-104 shares similar physical dimensions but differs in position count. The series is designed for reliable interconnection in industrial and commercial applications requiring durable edgeboard connections.

Replacement Considerations

Direct substitutes include other EDAC 306 series parts with matching 56-position and 0.156-inch spacing configurations. Cross-referencing with identical mechanical drawings is necessary to ensure compatibility with existing panel cutouts and board thicknesses.
