306-019-420-178

Edgeboard Connectors Overview

The EDAC Inc. part number 306-019-420-178 is a standard card edge connector from the 306 series, designed for through-hole mounting with a straight orientation. It features a dual-edge female configuration with 38 positions and a pitch of 0.156 inches (3.96 mm). The contacts are made of copper alloy with tin plating, rated for 5 A current. The housing is constructed from green thermoplastic polyester, suitable for board thicknesses within specified mechanical limits.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for non-specified card types
• Through-hole solder termination with straight mounting style
• Copper alloy contacts with tin plating for reliable signal transmission
• Green thermoplastic polyester housing material

Edgeboard Connectors Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Consumer electronics module interfaces
• Automotive electronic circuit boards

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm the contact plating type, as variations exist within the 306 series. Ensure the target PCB design accommodates the 3.96 mm pitch and 38-position footprint. Confirm that the tin-plated contacts meet the environmental requirements for the intended application, as gold-plated alternatives are available in this series.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 3.96 mm pitch is required. The tin plating offers cost-effective conductivity suitable for general-purpose applications. Consider the straight through-hole mounting profile for standard vertical board integration. Verify that the green polyester housing meets thermal and mechanical constraints for the assembly environment.

Edgeboard Connectors Part Context

This component belongs to the EDAC 306 series of card edge connectors, which provides various configurations for double-sided edge cards. The series utilizes a robust thermoplastic polyester housing and copper alloy contacts. The 306-019-420-178 variant specifically addresses needs for 38-position connections with a 0.156-inch spacing, offering a standardized solution for high-density board-to-board or board-to-backplane interfaces.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 306 series parts with matching 38 positions and 3.96 mm pitch. Variants such as 306-019-420-104 may differ in plating or color but share the same mechanical form factor. Always verify pin count, pitch, and mounting style before cross-referencing with alternative manufacturers' offerings.
