306-019-421-178

Edgeboard Connectors Overview

The EDAC Inc. 306-019-421-178 is a standard card edge connector designed for through-hole mounting. It features 38 positions with a contact spacing of 0.156 inches (3.96 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). It utilizes gold-plated copper alloy contacts and a thermoplastic polyester housing. Rated for 5 A current, it operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for non-specified card types
• Gold-plated contacts ensure reliable signal transmission
• Thermoplastic polyester housing provides structural integrity
• Through-hole solder termination for secure PCB attachment

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Communication equipment board-to-board connections
• Consumer electronics assembly lines
• Medical device internal circuitry integration

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm plating, housing material, and mounting style compatibility. Ensure the target application supports the required 3.96 mm pitch and 1.57 mm board thickness specifications before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 38 positions is required. Confirm that the design accommodates the 0.156-inch contact spacing and through-hole mounting constraints. Verify thermal requirements align with the -40°C to 105°C operating range and that the 5 A current rating meets system demands.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 series of standard card edge connectors. The series is characterized by its .156 inch contact spacing and low-profile insulator body design. These connectors are engineered for high-density applications where reliable electrical connection between edgeboards and backplanes is critical.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC cross-reference documentation for verified substitute part numbers. Do not assume interchangeability based on pin count alone; verify pitch, housing material, and termination type match.
