M20-7873842

Overview

The M20-7873842 is a rectangular connector receptacle from the Harwin M20 series, designed for board-to-board or cable stacking applications. It features 74 positions with a 0.100-inch (2.54mm) pitch arranged in two rows. The unit utilizes gold-plated phosphor bronze contacts housed in black polyamide insulation rated UL94 V-0. Rated for 3A current and 1000V voltage, it operates within a temperature range of -40°C to 105°C. The assembly employs a push-pull locking mechanism and offers stack heights of 11.04mm or 12.63mm.

Feature Summary

Push-pull locking mechanism ensures secure mating retention
Gold-plated phosphor bronze contacts provide reliable conductivity
Polyamide insulation housing meets UL94 V-0 flammability standards

Applications

General purpose interconnects
Industrial equipment connections
Telecommunications systems

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm specific stack height requirements (11.04mm or 12.63mm) against design specifications. Ensure compatibility with mating header pins regarding contact surface thickness and alignment tolerances. Check for RoHS compliance documentation if required by project regulations.

Selection Notes

Select this component for high-density vertical interconnects requiring robust mechanical retention. The dual-row configuration supports significant pin counts within a standard 2.54mm grid. Consider the push-pull feature for applications demanding frequent disconnection or vibration resistance. Validate thermal performance limits against operational environment constraints.
