Overview
The EDAC Inc. 306-028-521-108 is a standard card edge connector receptacle designed for dual-edge board applications. It features 28 positions with a female contact configuration and a 0.156-inch (3.96mm) centerline spacing. The unit utilizes gold-plated contacts on a copper alloy substrate to ensure reliable signal transmission. The housing is constructed from thermoplastic polyester, providing structural integrity and an insulation resistance of 5 GOhms. Rated for 5 A current, this green-colored component accepts printed circuit boards with nominal thicknesses suitable for its .156-inch pitch design.
Feature Summary
- Dual-edge female connector configuration for secure board insertion
- Gold-plated copper alloy contacts for enhanced conductivity
- Thermoplastic polyester housing for high insulation resistance
- Standard 0.156-inch centerline spacing for compatibility
Applications
- General electronic equipment interconnections
- Industrial control system modules
- Communication hardware interfaces
Procurement Notes
Verify the specific ordering suffix against official EDAC documentation to confirm exact plating thickness and housing color variations. Ensure the procurement specification matches the required 28-position count and 0.156-inch pitch. Confirm that the thermal rating aligns with the intended operational environment before finalizing purchase orders.
Selection Notes
Select this component when a dual-edge receptacle with 28 positions is required. The 0.156-inch spacing dictates the compatible PCB trace width. Verify that the target application does not exceed the 5 A current rating. Consider the thermoplastic polyester material properties for environmental resistance requirements.
Part Context
This part belongs to the EDAC standard card edge connector series. It is engineered for through-hole mounting onto parent boards. The design supports high-density connections in compact form factors. The product line emphasizes reliability in industrial and commercial environments.
Replacement Considerations
Cross-reference with EDAC part numbers sharing the same 28-position count and 0.156-inch pitch. Verify mechanical dimensions and electrical ratings match exactly before substitution.
