Overview
The EDAC Inc. 306-021-400-168 is a dual-edge female edgeboard connector designed for board-to-board interconnection. It features 42 positions with a contact spacing of 0.156 inches (3.96 mm). The connector utilizes tin-plated contacts and accepts printed circuit boards with a thickness ranging from 0.054 to 0.070 inches (1.37 mm to 1.78 mm). The insulator body is green, and the component is classified under non-specified dual-edge card types.
Feature Summary
- Dual-edge female configuration for secure board insertion
- Tin-plated contact surfaces for reliable electrical connection
- Green insulator body constructed for standard industrial environments
Applications
- Edgeboard interconnection in industrial control systems
- Signal routing in general-purpose electronic assemblies
- Board mounting in equipment requiring dual-edge access
Procurement Notes
Verify that the target application requires a 0.156-inch pitch and accommodates a board thickness within the 1.37 mm to 1.78 mm range. Confirm compatibility with tin-plated termination requirements. Ensure the design supports dual-edge female connectors and matches the physical dimensions of the green insulator body before finalizing procurement.
Selection Notes
Select this component when a 42-position dual-edge interface is required with a 3.96 mm contact spacing. It is suitable for applications where tin plating is acceptable and the PCB thickness falls between 1.37 mm and 1.78 mm. Consider the green color coding if visual identification is necessary for assembly processes.
Part Context
This part belongs to the EDAC 306 series of edgeboard connectors, which are engineered for robust board-to-board connections. The series offers various configurations including different pin counts, spacings, and termination options. The 306-021-400-168 specifically addresses needs for higher position counts with a wider pitch compared to finer-pitch alternatives.
Replacement Considerations
Direct substitutes must match the 42-position count, 0.156-inch pitch, and dual-edge female configuration. Verify that alternative components support the same PCB thickness range and utilize compatible tin-plated contacts. Cross-reference mechanical dimensions to ensure fit within the existing enclosure or board layout.
