3-640861-6

Edgeboard Connectors Overview

The 3-640861-6 is a single-edge female card edge connector from the MTA-156 series by TE Connectivity AMP Connectors. It features 6 positions with a 0.156-inch (3.96 mm) pitch and utilizes tin-plated phosphor bronze contacts. Designed for through-hole termination, this component supports 22 AWG wire gauge connections. The housing is constructed from thermoplastic polyester, rated for operation between -55°C and 105°C, ensuring reliable signal transmission in standard electronic assemblies.

Edgeboard Connectors Feature Summary

• Single-edge female contact configuration for standardized card insertion
• Through-hole termination method ensures secure PCB mounting
• Tin-plated phosphor bronze contacts provide corrosion resistance
• Thermoplastic polyester insulation supports high-temperature environments

Edgeboard Connectors Applications

• Standard electronic assembly interconnects
• Signal transmission in industrial equipment
• Power distribution in consumer electronics

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm plating thickness and material composition, as variations exist within the MTA-156 family. Ensure compatibility with the target card thickness of 0.062 inches (1.57 mm). Confirm that the through-hole footprint matches the design requirements. Check for RoHS compliance status if restricted substances are a concern for the final product application.

Edgeboard Connectors Selection Notes

Select this connector when a single-edge interface with a 3.96 mm pitch is required. The 6-position count suits moderate density applications. Consider the tin plating for general-purpose use rather than high-cycle mating scenarios. Verify that the 22 AWG wire gauge capability aligns with the harness specifications. Ensure the operating temperature range meets the environmental demands of the installation site.

Edgeboard Connectors Part Context

This component belongs to the MTA-156 series, a widely used line of card edge connectors known for reliability in various industries. The series offers multiple position counts and termination styles. The 3-640861-6 specifically addresses needs for single-edge, female contacts with through-hole mounting, providing a robust solution for connecting circuit boards to backplanes or cables.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other MTA-156 series connectors with matching 6-position single-edge female configurations. Verify that alternative part numbers maintain the same 0.156-inch pitch and through-hole termination style. Ensure the replacement shares the same housing material and temperature rating to guarantee mechanical and electrical compatibility.
