3-640866-3

Edgeboard Connectors Overview

The 3-640866-3 is a single-row female edge connector from the MTA-156 series by TE Connectivity AMP Connectors. It features 3 positions with a 0.156-inch (3.96 mm) contact spacing. The contacts are made of phosphor bronze and finished with tin plating, measuring 80.0 µin (2.03 µm) in thickness. Designed for panel mounting, it utilizes an IDC termination method suitable for non-specified single-sided cards up to 0.062 inches thick. The insulation material is polyester thermoplastic, and the housing is red.

Edgeboard Connectors Feature Summary

• Single-sided female edge connector design for board-to-board or card connections
• Insulation Displacement Contact (IDC) termination for rapid assembly
• Phosphor bronze contacts with tin plating for reliable signal transmission
• Panel mount configuration with top mount opening flange feature

Edgeboard Connectors Applications

• Electronic equipment requiring single-sided card interconnection
• Panel-mounted circuit board assemblies
• Industrial control systems using IDC termination methods

Edgeboard Connectors Procurement Notes

Verify component authenticity through authorized TE Connectivity channels or certified distributors. Confirm RoHS compliance status and current production lifecycle stage prior to ordering, as this specific part number may be subject to discontinuation notices. Ensure packaging specifications match project requirements for handling and storage conditions.

Edgeboard Connectors Selection Notes

Select this connector when a single-row, three-position female interface is required for non-specified single-sided cards. The 0.156-inch pitch accommodates standard card thicknesses up to 0.062 inches. Verify that the application environment supports the operating temperature range of -55°C to 105°C and that IDC tooling compatibility is established for the tin-plated phosphor bronze contacts.

Edgeboard Connectors Part Context

This component belongs to the MTA-156 series of edge connectors, widely utilized in industrial and commercial electronics for secure card insertion. The series offers various position counts and termination styles, providing standardized interfaces for modular electronic designs. The 3-640866-3 variant specifically addresses low-pin-count applications requiring robust panel-mount solutions.

Edgeboard Connectors Replacement Considerations

Check TE Connectivity official documentation for direct cross-reference part numbers. Alternative suppliers may offer compatible single-row IDC edge connectors with identical 0.156-inch pitch and 3-position configurations, but mechanical fit and electrical ratings must be validated against original specifications.
