M20-7831642

Overview

The M20-7831642 is a rectangular connector socket manufactured by Harwin Inc., featuring 32 positions with a 0.100 inch (2.54 mm) pitch. It utilizes a dual-row configuration designed for board-to-board or cable stacking applications. The contacts are female sockets made of phosphor bronze, finished with gold plating on the mating surface and tin on the termination side. Rated for 3A current and 1000V voltage, it operates within a temperature range of -40°C to 105°C. The housing is constructed from black polyamide (PA6T) nylon meeting UL94 V-0 flammability standards.

Feature Summary

• Dual-row female socket design for high-density interconnects
• Gold-plated mating contacts ensure reliable signal transmission
• Push-pull locking mechanism provides secure mechanical retention
• UL94 V-0 rated polyamide insulation for thermal stability

Applications

• Board-to-board stacking connections
• Cable-to-board interconnections
• Industrial control systems

Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status and check for end-of-life notifications prior to procurement. Ensure storage conditions maintain contact integrity. Validate pin count and row configuration against schematic requirements. Request batch-specific documentation for quality assurance records.

Selection Notes

Select this component when a 32-position dual-row female interface is required. Verify that the 2.54mm pitch matches the mating header dimensions. Ensure the operating voltage does not exceed 1000V and current load remains within 3A limits. Confirm PCB mounting style aligns with assembly capabilities. Check stack height requirements against available variants.

Part Context

This part belongs to the Harwin M20 series, a family of robust rectangular connectors designed for demanding environments. The series offers various position counts and row configurations. The M20-7831642 specifically addresses needs for medium-density connections requiring high reliability and precise alignment in compact assemblies.

Replacement Considerations

M20-7831642 is marked as obsolete. Potential substitutes include M20-7831646 or similar series variants. Verify pin count, pitch, and termination type compatibility before substitution. Consult official obsolescence notices for recommended replacement paths.
