Overview
The EDAC Inc. 306-028-400-101 is a dual female card edge connector designed for printed circuit board applications. It features a contact spacing of 0.156 inches (3.96mm) with a single centerline row configuration. The component accepts nominal PCB thicknesses of 0.062 inches (1.57mm). It provides 56 positions and utilizes a low-profile insulator body constructed from thermoplastic polyester. The connector supports a current rating of 5 A and offers an insulation resistance of 5 GOhms, with a maximum operating temperature of +105°C.
Feature Summary
- Dual female contact configuration with 56 positions
- Accepts 0.062 inch nominal thickness PCBs
- Low profile insulator body design
Applications
- General purpose electronic interconnections
- Industrial control systems
- Communication equipment modules
Procurement Notes
Verify the specific ordering suffix to ensure compatibility with required PCB thickness and termination style. Confirm that the thermoplastic polyester housing material meets environmental requirements for the intended application. Cross-reference the 56-position count against schematic designs to prevent mismatched assembly issues during production integration.
Selection Notes
Select this component when a dual-sided card edge interface is required for standard 0.062-inch boards. The 0.156-inch spacing accommodates common trace widths while maintaining signal integrity. Ensure the 5 A current rating aligns with power distribution needs and that the +105°C thermal limit suits the operational environment without additional derating.
Part Context
This part belongs to the EDAC 306 series of card edge connectors, which are engineered for reliable vertical mating connections. The series emphasizes low-profile construction to support compact device form factors. The 306-028-400-101 variant specifically addresses high-density interconnection needs within industrial and commercial electronics sectors requiring robust mechanical retention.
Replacement Considerations
Direct substitutes include other EDAC 306 series variants with matching pin counts and spacing, such as the 306-028-400-112. Verify that alternative sources maintain identical 0.156-inch spacing and 56-position configurations to ensure mechanical fit.
