306-021-420-103

Overview

The EDAC Inc. 306-021-420-103 is a dual female card edge connector designed for panel mount and through-hole termination. It features 42 positions with a 0.156-inch (3.96mm) contact spacing across two rows. The connector utilizes copper alloy contacts with tin plating and a green thermoplastic polyester insulator. It accepts printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches. The component operates within a temperature range of -40°C to 105°C and complies with RoHS3 standards.

Feature Summary

• Dual female configuration with cantilever contacts for secure board retention
• Panel mount installation with flush mounting flange and top opening
• Tin-plated copper alloy contacts ensure reliable electrical performance
• Thermoplastic polyester insulator body provides structural stability

Applications

• Industrial control system interface connections
• Telecommunications equipment backplane interconnects
• Embedded computing module docking stations

Procurement Notes

Verify the specific part number against official EDAC documentation to confirm pin count and spacing requirements. Ensure that the target printed circuit board thickness falls within the specified operational range of 0.054 to 0.070 inches. Confirm that the application environment remains within the rated temperature limits of -40°C to 105°C to maintain connector integrity and electrical reliability during operation.

Selection Notes

Select this connector when a dual-sided female interface with 0.156-inch spacing is required for panel-mounted applications. The through-hole termination method suits high-vibration environments where solder joint strength is critical. Consider the green insulator color for visual identification if needed. Verify compatibility with standard card edge profiles before finalizing the design integration.

Part Context

This component belongs to the EDAC 306 series, which focuses on standard card edge connectors. The series offers various position counts and spacing options to accommodate different board densities. The 306-021-420-103 specifically addresses needs for moderate density interfaces requiring robust mechanical retention and standard thermal performance characteristics.

Replacement Considerations

Cross-reference with other EDAC 306 series variants for alternative position counts. Verify that any substitute maintains the same 0.156-inch spacing and dual female contact configuration. Ensure replacement parts match the through-hole mounting style and compatible PCB thickness specifications.
