Overview
The EDAC Inc. 306-035-421-103 is a dual-edge card edge connector designed for panel mount and through-hole termination. It features 70 positions with a female contact type and a 0.156-inch (3.96mm) spacing. The connector utilizes copper alloy contacts with tin plating and a green thermoplastic polyester insulator. It supports card thicknesses between 0.054 and 0.070 inches, operates within a temperature range of -40°C to 105°C, and complies with RoHS3 standards.
Feature Summary
- Dual-sided female contact configuration for secure board insertion
- Through-hole solder termination for robust mechanical stability
- Thermoplastic polyester insulation providing thermal resistance up to 105°C
Applications
- Industrial control system backplanes
- Telecommunications equipment interconnects
- Medical device circuit board assemblies
Procurement Notes
Verify the specific part number against official EDAC documentation to ensure compatibility with required card thickness and mounting constraints. Confirm that the tin-plated contacts meet environmental requirements for the intended application. Check for any updated compliance certifications such as RoHS3 or REACH status before finalizing procurement orders.
Selection Notes
Select this component when a dual-edge connector with 70 positions and 0.156-inch spacing is required. Ensure the PCB design accommodates through-hole mounting and panel installation. Verify that the operating temperature range of -40°C to 105°C aligns with the system's thermal environment and that the card thickness falls within the specified 0.054 to 0.070-inch limits.
Part Context
This connector belongs to the EDAC 306 series, which offers various configurations for card edge applications. The series provides options for different pin counts, mounting styles, and contact materials. The 306-035-421-103 specifically addresses needs for high-density dual-edge connections in industrial and commercial electronics requiring reliable signal transmission.
Replacement Considerations
Consult the EDAC 306 Series Ordering Guide for alternative part numbers with similar specifications. Consider variants with different contact counts or mounting styles if the current model does not fit spatial constraints. Ensure any substitute maintains the same spacing and card thickness compatibility.
