306-028-400-168

Overview

The EDAC Inc. 306-028-400-168 is a single-row card edge connector featuring 28 positions with a 0.156-inch (3.96mm) contact spacing. It utilizes tin-plated tail-type contacts for solder termination and is housed in a green insulator. The component supports board thicknesses of 0.051 to 0.071 inches, operates within a -55°C to 105°C temperature range, and complies with RoHS3 standards.

Feature Summary

• Single-row configuration with 28 signal contacts
• Tail-type contacts designed for through-hole soldering
• Green insulator housing with flush mounting capability

Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Consumer electronic circuit boards

Procurement Notes

Verify the specific datasheet version for the 306-028-400-168 part number to confirm exact dimensional tolerances and plating specifications. Ensure that the target PCB design accommodates the 0.156-inch pitch and the required tail length for reliable solder joint formation during assembly processes.

Selection Notes

Select this connector when a single-row interface with 28 positions is required. The 0.156-inch spacing distinguishes it from finer-pitch alternatives. Confirm that the application environment remains within the specified operating temperature range and that the board thickness falls within the accepted mechanical limits for proper engagement.

Part Context

This component belongs to the EDAC 306 series of standard card edge connectors. The series offers various row counts and spacing options to support diverse interconnection needs across industrial and commercial electronics sectors, providing a standardized solution for vertical board-to-board connections.

Replacement Considerations

Compatible substitutes include other EDAC 306 series variants with matching 28-position single-row layouts and 0.156-inch pitch, such as the 306-028-400-103, provided electrical and mechanical parameters align with the original design requirements.
