Overview
The EDAC Inc. 306-020-521-108 is an active standard card edge connector designed for dual female termination. It features a single centerline row with 40 positions and a contact spacing of 0.156 inches (3.96 mm). The component accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Gold-plated copper alloy contacts ensure reliable conductivity, while the green thermoplastic insulator body provides structural support. Rated for 5 A current at temperatures ranging from -40°C to +105°C, it offers high insulation resistance.
Feature Summary
- Dual female contact configuration for secure board insertion
- Gold-plated copper alloy contacts for enhanced conductivity
- Low-profile thermoplastic insulator body construction
- Vertical panel mount installation style
Applications
- Industrial control system interconnects
- Telecommunications equipment backplanes
- Consumer electronics module interfaces
- Automotive electronic sub-system connections
Procurement Notes
Verify part authenticity through authorized EDAC distributors or certified suppliers. Confirm RoHS compliance status and specific manufacturing lot codes against official documentation. Ensure storage conditions maintain contact integrity prior to assembly. Cross-reference ordering suffixes to confirm exact pin count and plating specifications match project requirements.
Selection Notes
Select this connector when a 40-position dual female interface is required for 1.57 mm thick PCBs. The 3.96 mm pitch suits applications needing robust vertical mounting. Evaluate thermal limits against operational environments. Consider gold plating durability for repeated mating cycles in industrial settings.
Part Context
This component belongs to the EDAC 306 series of standard card edge connectors. The series emphasizes low-profile designs with reliable single-row configurations. Variants within the series differ primarily in position count and housing color, maintaining consistent mechanical and electrical performance standards across the product line.
Replacement Considerations
Direct substitutes include EDAC 306-020-521-168 and 306-020-521-101. These alternatives share identical mechanical dimensions and electrical ratings. Verify housing color differences if aesthetic consistency is critical for the assembly.
