M20-7871642

Overview

The Harwin M20-7871642 is a dual in-line (DIL) surface mount socket assembly featuring 32 positions arranged in two rows. It utilizes a 2.54 mm (0.1 inch) pitch and employs straight female contacts designed for board-to-board or cable stacking applications. The connector incorporates a locking mechanism to ensure secure mating and uses black insulator material. Operating within a temperature range of -40°C to 105°C, this component is currently listed as active with tube packaging.

Feature Summary

• Dual row configuration supporting high-density interconnects
• Integrated locking mechanism for secure connection stability
• Surface mount terminal style for automated PCB assembly

Applications

• Board-to-board connections
• Cable stacking assemblies
• General electronic equipment interconnects

Procurement Notes

Verify the current availability status directly with authorized distributors or the manufacturer, as supply chain conditions may change. Confirm that the specific ordering suffix matches the required contact plating and housing color specifications for your design. Ensure compatibility with standard SMT reflow profiles and check for any updated environmental compliance documentation prior to final procurement.

Selection Notes

Select this component when a locked, dual-row surface mount interface is required for reliable signal transmission. Consider the 2.54 mm pitch constraints and the physical height limitations of the PCB stack-up. Verify that the mating header provides compatible locking features to engage the socket's retention system effectively during assembly.
