306-032-421-158

Overview

The EDAC Inc. 306-032-421-158 is a dual-edge female card edge connector designed for through-hole mounting. It features 64 positions with a 0.156-inch (3.96mm) contact spacing and accepts PCBs with a thickness range of 0.054 to 0.070 inches. The contacts are made of copper alloy with tin plating, housed in a green thermoplastic polyester insulator. This component supports a wide operating temperature range from -40°C to 105°C and complies with RoHS3 standards.

Feature Summary

• Dual-edge female configuration with cantilever contacts for secure board insertion
• Through-hole termination method ensuring robust mechanical stability
• Tin-plated copper alloy contacts providing reliable electrical conductivity
• Green thermoplastic polyester insulation body for environmental durability

Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Consumer electronic module connections
• Medical device circuit board interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating type and flange characteristics. Ensure the selected variant matches the required PCB thickness tolerance and mounting style. Cross-reference the part number with current regulatory compliance documentation to confirm RoHS3 status before final procurement decisions.

Selection Notes

Select this connector when a dual-edge interface with 0.156-inch spacing is required for through-hole assembly. Consider the tin-plated contact finish for general-purpose applications where gold plating is not specified. Evaluate the thermal rating and mechanical strain relief needs against the operational environment requirements.

Part Context

This component belongs to the EDAC 306 Series, which specializes in card edge connectors with 0.156-inch contact spacing. The series offers various position counts and termination styles, catering to diverse industrial and commercial connectivity needs while maintaining consistent dimensional standards across the product line.

Replacement Considerations

Direct substitutes within the same series include variants with different position counts or plating options, such as the 306-032-420-158. Verify compatibility by comparing flange dimensions, PCB thickness tolerances, and terminal row configurations.
