Overview
The EDAC Inc. 306-021-420-107 is a standard card edge connector from the 306 series, designed for panel mount applications with a vertical orientation. It features a dual female configuration with 42 positions arranged in two rows, utilizing a 0.156-inch (3.96 mm) contact spacing. The connector accepts printed circuit boards with a thickness range of 0.054 to 0.070 inches (1.37 to 1.78 mm). Contact plating is tin, and the insulator material is thermoplastic polyester. It operates within a temperature range of -40°C to +105°C.
Feature Summary
- Dual female contact configuration for non-specified dual-edge card connections
- Vertical panel mount installation style with solder pin termination
- Low profile insulator body constructed from green thermoplastic polyester
Applications
- Industrial control systems requiring robust card edge interfaces
- Communication equipment board interconnections
- Consumer electronics assembly with vertical mounting constraints
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required board thickness and contact plating specifications. Confirm that the dual-edge design aligns with the target PCB layout. Check regional availability as distribution status may vary by location. Ensure compliance with RoHS3 regulations if required for the end application.
Selection Notes
Select this component when a vertical, panel-mounted solution is required for dual-edge cards. The 3.96 mm pitch accommodates standard board widths. Verify that the tin-plated contacts meet the environmental requirements for the intended operating conditions. Consider the 42-position count relative to signal density needs. Ensure the housing color and material properties suit the assembly environment.
Part Context
This part belongs to the EDAC 306 series of standard card edge connectors. The series offers various position counts and configurations for both single and dual-edge applications. The 306 series is characterized by its thermoplastic polyester insulation and reliable solder pin termination, suitable for general-purpose electronic interconnects across multiple industries.
Replacement Considerations
Consult the official EDAC 306 Series Ordering Guide for direct substitutes with different position counts or plating options. No public confirmed substitute part numbers are identified in the provided documentation.
