M20-7881042

Overview

The M20-7881042 is a 20-position receptacle connector from the Harwin M20 series, designed for board-to-board applications. It features a 2.54 mm (0.100 inch) pitch and utilizes a right-angle through-hole mounting configuration. The connector employs female socket contacts with gold plating to ensure reliable signal transmission. Constructed with high-performance insulating materials, it supports standard PCB assembly processes while maintaining structural integrity in compact electronic designs.

Feature Summary

• Right-angle through-hole mounting design for efficient PCB space utilization
• Gold-plated female socket contacts for enhanced conductivity and corrosion resistance
• Standard 2.54 mm pitch spacing compatible with industry-standard headers

Applications

• Board-to-board interconnections in industrial control systems
• High-density electronic assemblies requiring right-angle routing
• Consumer electronics with strict height and space constraints

Procurement Notes

Verify component authenticity by checking manufacturer markings and datasheet specifications against official Harwin documentation. Confirm that the right-angle orientation and gold contact plating match project requirements. Ensure compatibility with mating pin headers regarding pitch and row configuration before finalizing procurement decisions.

Selection Notes

Select this model when right-angle connectivity is required for 20-position interfaces. The gold plating offers superior performance over tin variants in corrosive environments. Consider the through-hole footprint dimensions and mechanical retention needs during PCB layout to ensure proper installation and long-term reliability.

Part Context

This component belongs to the M20 series, which provides robust solutions for board-to-board connections. The series includes various configurations with different contact counts and orientations. The M20-7881042 specifically addresses needs for angled insertion paths while maintaining the electrical characteristics expected from the broader M20 family of connectors.

Replacement Considerations

Compatible substitutes within the M20 series include models with identical 20-position counts and right-angle through-hole mounting. Verify that alternative part numbers maintain the same 2.54 mm pitch and gold contact specifications to ensure interchangeability without redesigning the PCB footprint.
