Overview
The EDAC Inc. 306-034-420-103 is a dual-edge female card edge connector with 68 positions arranged in a single centerline row. It features a 0.156-inch (3.96mm) contact spacing and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). The connector utilizes tin-plated copper alloy contacts and a green thermoplastic polyester insulator body. Designed for panel mount installation via through-hole soldering, it operates within a temperature range of -40°C to +105°C.
Feature Summary
- Dual female contact design accommodates double-sided edge cards
- Flush mount flange with floating bobbin feature for secure alignment
- Low profile insulator body construction for compact integration
Applications
- Connecting expansion cards to motherboards
- Linking printed circuit boards to backplanes
- General-purpose edge board interconnections
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current 306 Series Ordering Guide to ensure compatibility with required termination styles and plating options. Confirm that the target application supports the specified 0.156-inch pitch and board thickness constraints before finalizing procurement decisions.
Selection Notes
Select this component when a dual-edge interface with a 3.96mm pitch is required for robust mechanical stability. The flush mount configuration with a floating bobbin provides precise card guidance. Ensure the system environment remains within the -40°C to +105°C operating range and that the PCB thickness aligns with the 1.57mm nominal specification.
Part Context
This part belongs to the EDAC 306 series of standard card edge connectors. The series offers various configurations including single and dual rows, multiple mounting styles, and different contact materials. The 306-034-420-103 specifically addresses applications requiring high-density dual-edge connections with a standardized 0.156-inch spacing.
Replacement Considerations
Consult the official EDAC 306 Series cross-reference documentation for verified substitute part numbers. Direct replacements must match the 68-position count, 0.156-inch pitch, and dual-edge female configuration to maintain mechanical and electrical integrity.
