306-032-421-103

Overview

The EDAC Inc. 306-032-421-103 is a dual-edge female card edge connector designed for panel mount and through-hole termination. It features 64 positions with a 0.156-inch (3.96mm) contact spacing across two rows. The connector utilizes tin-plated copper alloy contacts and a green thermoplastic polyester insulator. It accepts printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches (1.37mm to 1.78mm). The component operates within a temperature range of -40°C to 105°C and complies with RoHS 3 standards.

Feature Summary

• Dual-edge female configuration with cantilever contacts for secure board retention
• Through-hole termination with flanged mounting for stable panel installation
• Tin-plated copper alloy contacts ensuring reliable electrical connectivity

Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• General-purpose electronic module interfaces

Procurement Notes

Verify the specific pin count and contact spacing against design requirements before ordering. Confirm that the target PCB thickness falls within the specified 0.054 to 0.070 inch range to ensure proper mechanical engagement. Check for RoHS 3 compliance if environmental regulations apply to the final assembly. Ensure the through-hole footprint matches the connector's terminal dimensions for correct soldering.

Selection Notes

Select this model when a dual-sided connection is required for high-density signal routing. The 0.156-inch spacing accommodates standard board layouts while maintaining robust mechanical stability. Consider the operating temperature range and material compatibility with adjacent components. Verify that the green insulator color meets any visual identification standards for the assembly line.

Part Context

This component belongs to the EDAC 306 series, which specializes in standard card edge connectors. The series offers various position counts and termination styles to support diverse electronic packaging needs. The 306-032-421-103 variant specifically addresses applications requiring dual-edge access with through-hole reliability.

Replacement Considerations

Direct substitutes include other EDAC 306 series connectors with matching 64-position dual-edge specifications. Verify identical spacing and termination methods before cross-referencing with alternative manufacturers. Ensure mechanical dimensions and mounting hole patterns align perfectly with existing PCB layouts.
