Overview
The EDAC Inc. 306-023-420-178 is a standard card edge connector receptacle designed for vertical panel mount applications. It features a single row with 23 positions and a contact spacing of 3.96 mm (0.156 inches). The component accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Electrical specifications include a current rating of 5 A and an insulation resistance of 5 GOhms. The contacts are gold-plated copper alloy, while the insulator body is constructed from thermoplastic polyester. Operating temperature ranges from -40°C to +105°C.
Feature Summary
- Vertical panel mount receptacle configuration
- Gold-plated copper alloy contacts for reliable signal transmission
- Thermoplastic polyester insulator body construction
- Accepts 1.57 mm nominal thickness PCBs
Applications
- High-temperature electronic assemblies
- Panel-mounted interface connections
- Single-row card edge board integration
Procurement Notes
Verify the specific ordering suffix against official EDAC documentation to ensure correct plating and material specifications. Confirm that the 23-position single-row configuration matches the target PCB design requirements. Check RoHS compliance details directly in the datasheet as indicated by manufacturer listings. Ensure compatibility with 1.57 mm board thickness before procurement.
Selection Notes
Select this component when a vertical, panel-mount solution is required for single-sided card edge interfaces. The 3.96 mm pitch accommodates standard 0.062 inch thick boards. Consider the 5 A current rating and 105°C maximum operating temperature for thermal management needs. Verify that the gold-plated contacts meet the environmental durability requirements for the intended application environment.
Part Context
This part belongs to the EDAC standard card edge connector family, specifically designed for robust industrial and commercial interconnect solutions. The 306 series utilizes a low-profile insulator body to minimize spatial requirements while maintaining structural integrity. It serves as a reliable interface between edgeboard connectors and system backplanes or chassis panels.
Replacement Considerations
Cross-reference with EDAC 307-023-431-178 for similar positioning but different series characteristics. Verify pin count and pitch compatibility before substitution. Ensure mechanical dimensions align with existing panel cutouts and board thickness constraints.
