3-641284-3

Edgeboard Connectors Overview

The 3-641284-3 is a single-row, female card edge connector from the MTA-156 series by TE Connectivity AMP Connectors. It features three contacts with a 0.156-inch (3.96mm) pitch and utilizes an IDC terminal type for wire termination. The housing is yellow polyamide, and contacts are tin-plated brass. Rated for 7.5A current and 500V voltage, it supports non-specified single-edge cards. The component is RoHS compliant and lead-free, designed for reliable signal transmission in electronic assemblies.

Edgeboard Connectors Feature Summary

• IDC termination mechanism for rapid wire assembly without soldering
• Single-row female contact configuration for standard card edge interfaces
• Yellow polyamide housing providing electrical insulation and mechanical stability

Edgeboard Connectors Applications

• Industrial control system interconnects
• Consumer electronics module connections
• Telecommunications equipment backplanes

Edgeboard Connectors Procurement Notes

Verify the specific datasheet version to confirm current lifecycle status, as distributor listings may indicate obsolete or new manufacturing states. Ensure compatibility with mating card edge thicknesses specified in the official TE Connectivity documentation. Check for any recent supply chain updates or alternative part numbers if this specific variant is discontinued.

Edgeboard Connectors Selection Notes

Select this connector when a single-row, female IDC interface is required for 3-wire applications. The 0.156-inch pitch dictates the compatible card edge width. Consider the MTA-156 series robustness for environments requiring reliable press-fit wire connections. Verify that the 500V rating meets the circuit requirements.

Edgeboard Connectors Part Context

Part of the MTA-156 family, known for rugged performance in demanding environments. This series originated from TE's legacy of reliable press-fit technology developed for aerospace and military applications, now widely used in commercial industrial sectors for secure, high-reliability interconnections.

Edgeboard Connectors Replacement Considerations

Cross-reference with other MTA-156 variants for different pin counts. Verify dimensional compatibility with existing PCB footprints and mating connectors before substitution.
