306-023-521-168

Overview

The EDAC Inc. 306-023-521-168 is a dual-edge female card edge connector designed for vertical PCB mounting. It features 46 positions with a 0.156-inch (3.96mm) contact spacing and accepts printed circuit boards with a thickness of 0.062 inches (1.57mm). The contacts are constructed from copper alloy with gold plating, housed in a green thermoplastic polyester insulator. Rated for operation between -40°C and +105°C, it utilizes solder pin termination for secure attachment to the host board.

Feature Summary

• Dual-edge female configuration supporting single central row connectivity
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Thermoplastic polyester insulator provides thermal stability up to 105°C
• Vertical panel mount design accommodates standard 0.062-inch board thickness

Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Medical device circuit board assemblies
• Consumer electronics internal module connections

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact mechanical dimensions and termination style. Ensure compatibility with the target PCB thickness of 0.062 inches. Confirm RoHS compliance status if required by project specifications. Cross-reference the 46-position count to prevent mismatching with similar series variants.

Selection Notes

Select this component when a dual-edge interface is required for vertical mounting applications. The 0.156-inch pitch suits general-purpose signal routing rather than high-density micro-electronics. Consider the green insulator color for visual identification during assembly. Verify that the 46-contact capacity aligns with the circuit requirements without excess unused pins.

Part Context

This part belongs to the EDAC 306 series of standard card edge connectors. The series is characterized by low-profile insulator bodies and versatile mounting options. It serves as a robust solution for connecting peripheral cards to main systems in industrial and commercial environments where reliable mechanical retention and electrical continuity are essential.

Replacement Considerations

Direct substitutes within the same series include 306-023-521-107 and 306-023-521-112. These alternatives share identical positioning and pitch but may differ in housing material or termination specifics. Always validate dimensional drawings before substitution.
