Overview
The M20-8751042 is a male pin header connector from the Harwin M20 series, designed for surface mount technology. It features a dual-row configuration with 20 positions and a standard 2.54 mm (0.1 in) pitch. The housing is constructed from black nylon, providing electrical insulation and mechanical stability. The contacts are made of brass with gold plating to ensure reliable signal transmission and corrosion resistance. Rated for 3 A current and 250 V voltage, this component supports board-to-board or wire-to-board interconnections within an operating temperature range of -40°C to 105°C.
Feature Summary
- Dual-row surface mount design for compact PCB integration
- Gold-plated brass contacts for enhanced conductivity
- Nylon housing rated for high-temperature environments
Applications
- Board-to-board interconnects
- Wire-to-board connections
- High-density electronic assemblies
Procurement Notes
Verify the specific ordering suffix against the official datasheet to confirm contact plating thickness and housing color variants. Ensure compatibility with automated surface mount assembly processes by checking peak reflow temperature limits. Confirm that the selected variant meets the required current and voltage ratings for the target application environment.
Selection Notes
Select this component when a low-profile, dual-row header is required for surface mounting. The 2.54 mm pitch ensures compatibility with standard PCB footprints. Consider the 3 A rating and 250 V insulation for general signal and power distribution tasks. Verify thermal endurance requirements against the 105°C maximum operating limit before finalizing the design.
Part Context
This part belongs to the Harwin M20 series, a family of connectors known for their slim profile and robust construction. The series offers various row counts and pin configurations to support diverse connectivity needs. The M20-8751042 specifically addresses applications requiring a 20-position dual-row interface with surface mount capabilities.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other Harwin M20 series variants if different pin counts or row configurations are needed.
