M20-8761042

Headers, Male Pins Overview

The M20-8761042 is a surface mount header connector from the Harwin M20 series, featuring a 2.54 mm (0.100 inch) pitch and 20 positions in a dual inline configuration. It utilizes square brass contacts with gold plating on the mating interface and tin plating on the tail for soldering. The housing is constructed from black polyamide (PA6T) nylon rated UL94 V-0, supporting a current rating of 3A per contact at 250V. Designed for board-to-board or cable applications, it operates within a temperature range of -40°C to 105°C and includes pick-and-place compatibility features.

Headers, Male Pins Feature Summary

• Dual inline surface mount design with cuttable construction for flexible positioning
• Gold-plated square contacts ensure reliable signal transmission and corrosion resistance
• Polyamide insulation housing provides high thermal stability and UL94 V-0 flammability rating
• Integrated pick-and-place compatible structure facilitates automated assembly processes

Headers, Male Pins Applications

• High-density board-to-board interconnections
• Cable-to-board wiring assemblies
• Automated surface mount technology production lines
• Industrial control module interfaces

Headers, Male Pins Procurement Notes

Verify that the specific part number matches the required pin count and pitch specifications before ordering. Confirm that the surface mount orientation aligns with the PCB layout requirements. Ensure that the selected variant supports the necessary environmental operating conditions and electrical ratings for the intended application environment.

Headers, Male Pins Selection Notes

Select this component when a dual-row surface mount header with a standard 2.54 mm pitch is required. Consider the 3A current rating and 250V voltage limit for circuit design constraints. Evaluate the need for cuttable features if custom lengths are necessary. Verify compatibility with automated pick-and-place equipment due to the specific housing geometry designed for machine handling.

Headers, Male Pins Part Context

This connector belongs to the Harwin M20 series, which offers a range of vertical and right-angle headers. The M20-8761042 specifically represents a 20-position dual inline variant optimized for surface mount technology. It shares common mechanical and electrical characteristics with other parts in the series, differing primarily in position count and row configuration.

Headers, Male Pins Replacement Considerations

Direct substitutes must maintain the 2.54 mm pitch, 20-position count, and dual inline surface mount form factor. Verify that alternative components offer identical contact plating and insulation material properties to ensure consistent performance and reliability in existing designs.
