M20-7883842

Overview

The M20-7883842 is a rectangular connector header from the Harwin M20 series, designed for surface-mount technology applications. It features a dual-row configuration with 76 positions and a standard 0.100-inch (2.54mm) pitch. The connector utilizes square male pins with gold plating on the mating interface to ensure reliable signal transmission. Constructed with a black polyamide insulation body rated UL94 V-0 for flame resistance, it supports board-to-board or cable connections. The unit operates within a temperature range of -40°C to +105°C and carries a current rating of 3A per contact.

Feature Summary

Dual-row surface-mount design for compact high-density circuit layouts
Gold-plated square pin contacts for enhanced conductivity and corrosion resistance
UL94 V-0 rated polyamide insulation housing for thermal stability
Push-pull locking mechanism ensures secure mating engagement

Applications

Industrial control systems requiring robust interconnects
Telecommunications equipment backplanes
General-purpose electronic assemblies
Board-to-board data transmission modules

Procurement Notes

Verify the specific suffix codes against the official datasheet to confirm exact pin count and row configuration before ordering. Ensure compatibility with mating socket specifications regarding stack height and contact length. Confirm RoHS compliance status if required by project regulations. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components.

Selection Notes

Select this component when a high-pin-count, dual-row SMD header is required for space-constrained designs. Evaluate the 2.54mm pitch against available PCB trace spacing capabilities. Consider the 3A current rating relative to total power dissipation needs. Verify that the mounting footprint aligns with existing assembly tooling and solder paste stencils for surface-mount processes.

Part Context

This component belongs to the Harwin M20 series, a widely used family of rectangular connectors known for their versatility in mixed-signal environments. The M20 series offers various configurations including through-hole and surface-mount options. This specific model represents the high-density variant optimized for modern automated assembly lines while maintaining mechanical durability.
