M20-7833542

Overview

The Harwin M20-7833542 is a 70-position receptacle connector belonging to the M20 series, designed for board-to-board or cable interconnect applications. It features a 2.54 mm (0.100 inch) pitch and utilizes a dual-row configuration with female contacts. The unit employs a push-pull fastening mechanism and supports surface mount installation via solder termination. Constructed with UL94 V-0 rated polyamide insulation and phosphor bronze contacts, it operates within a temperature range of -40°C to +105°C.

Feature Summary

• Dual-row receptacle design optimized for high-density board-to-board stacking
• Push-pull fastening system ensures secure mechanical retention during mating cycles
• Surface mount termination facilitates automated PCB assembly processes

Applications

• Board-to-board interconnects in industrial equipment
• Cable-to-board connections in telecommunications infrastructure
• High-density electronic module stacking in general electronics

Procurement Notes

Verify the specific contact plating specification against project requirements, as datasheet references may vary between gold and tin finishes. Confirm the exact stack height options available for the current production version. Ensure compatibility with the designated mating header series before finalizing procurement orders.

Selection Notes

Select this component when a 70-pin interface is required for rigid board-to-board connections. The 2.54 mm pitch suits standard density layouts. Consider the push-pull mechanism if vibration resistance is critical. Verify that the surface mount profile fits within the allowable Z-axis clearance constraints of the enclosure design.

Part Context

This part belongs to the Harwin M20 series, a family of rectangular connectors known for compact designs and robust performance. The series offers various row counts and mounting styles, including through-hole and surface mount options. The M20-7833542 specifically addresses the need for high-pin-count receptacles in space-constrained environments requiring reliable signal transmission.

Replacement Considerations
