Overview
The EDAC Inc. 306-021-400-158 is a dual-edge female card edge connector designed for panel and through-hole mounting. It features 42 positions with a 0.156-inch (3.96mm) pitch across two rows. The contacts are made of copper alloy with a gold finish, ensuring reliable signal transmission. The housing is constructed from green thermoplastic polyester, rated for operation between -40°C and 105°C. This component supports board thicknesses ranging from 0.054 to 0.070 inches.
Feature Summary
- Dual-edge female contact configuration for secure board insertion
- Panel mount design with flange features including top opening and threaded inserts
- Gold-plated cantilever contacts for enhanced conductivity and durability
- Thermoplastic polyester insulation providing stable performance in varying temperatures
Applications
- Industrial control systems requiring robust card edge interfaces
- Telecommunications equipment utilizing standard 0.156 inch spacing
- Test and measurement devices needing high-density connections
- Automotive electronics operating within specified temperature ranges
Procurement Notes
Verify the specific ordering suffix to confirm contact plating thickness and material composition. Ensure compatibility with the target PCB card thickness range of 0.054 to 0.070 inches. Confirm that the panel mounting hole pattern matches the 4-40 threaded insert specifications. Check RoHS compliance status if required by project regulations.
Selection Notes
Select this connector when a dual-edge interface with a 0.156 inch pitch is required. Consider the 42-position count for circuit density needs. Evaluate the panel mount requirement against available chassis space. Compare thermal ratings against environmental conditions to ensure the -40°C to 105°C range is sufficient.
Part Context
This component belongs to the EDAC 306 series of card edge connectors. The series offers various pin counts and spacing options. The 306-021-400-158 specifically utilizes a 0.156 inch pitch. It is part of a broader lineup designed for general-purpose interconnect applications.
Replacement Considerations
Cross-reference with other EDAC 306 series parts for similar pitch and position counts. Verify mechanical dimensions and mounting hole patterns before substitution. Ensure electrical characteristics match the original design requirements.
