Overview
The EDAC Inc. 306-032-421-168 is a dual female card edge connector from the 306 series, designed for panel mount and through-hole termination. It features 64 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). Contact surfaces are tin-plated copper alloy, housed in a green thermoplastic polyester insulator. Operating temperature ranges from -40°C to +105°C.
Feature Summary
- Dual female configuration with low-profile insulator body
- Accepts standard 0.062 inch nominal thickness PCBs
- Single centerline row design for simplified routing
Applications
- Industrial control systems requiring robust board-to-board connections
- Communication equipment backplanes
- Consumer electronics internal interconnects
Procurement Notes
Verify that the target PCB thickness falls within the specified acceptance range of 0.062 inches nominal. Confirm that the application environment remains within the -40°C to +105°C operating temperature limits. Ensure compatibility with tin-plated contacts regarding corrosion resistance requirements. Check that the panel mounting flange dimensions align with the chassis opening specifications.
Selection Notes
Select this component when a dual female interface with 0.156-inch spacing is required for standard thickness boards. Consider the tin plating for cost-effective applications where high-cycle mating is not critical. Evaluate the single centerline row layout against routing density needs compared to multi-row alternatives. Verify that the green insulator material meets thermal and mechanical constraints of the assembly process.
Part Context
This part belongs to the EDAC 306 series of card edge connectors, which are characterized by their 0.156-inch pitch and panel-mount capability. The series offers various position counts and termination styles to support diverse electronic packaging requirements. The 306 series is widely utilized in industrial and commercial applications demanding reliable edge card interfaces.
Replacement Considerations
Cross-reference with other EDAC 306 series variants sharing the same 0.156-inch pitch and 64-position count. Verify mechanical fit and electrical continuity before substituting with different plating options or insulator colors.
