M20-8760242

Overview

The Harwin M20-8760242 is a surface mount pin header connector from the M20 series, designed for board-to-board or cable applications. It features a 2.54mm pitch with 4 positions arranged in a dual-row configuration. The connector utilizes brass contacts with gold plating on the mating interface and tin plating on the tail, housed in a black polyamide (PA6T) insulator rated UL94 V-0. Rated for 3A per contact at 250V, it operates within a temperature range of -40°C to 105°C. Key dimensions include an insulation height of 2.54mm and a mating contact length of 5.80mm.

Feature Summary

• Surface mount termination facilitates automated pick-and-place assembly processes.
• Gold-plated mating contacts ensure reliable signal transmission and corrosion resistance.
• Polyamide (PA6T) insulation provides high thermal stability and flame retardancy.

Applications

• Board-to-board interconnections
• Cable-to-board connections
• General electronic equipment internal wiring

Procurement Notes

Verify the specific part number against official Harwin documentation to confirm current lifecycle status and RoHS compliance. Ensure that the surface mount footprint matches the design guidelines provided in the manufacturer's datasheet. Confirm that the mating socket or header components are compatible with the specified 2.54mm pitch and contact geometry to guarantee proper mechanical engagement.

Selection Notes

Select this component when a low-profile, surface-mount header is required for compact designs. The dual-row layout maximizes connection density while maintaining standard spacing. Consider the operating temperature range and current rating to ensure suitability for the intended electrical load. Verify that the PCB copper area supports the soldering requirements for surface mount terminals.

Part Context

This component belongs to the Harwin M20 series, which defines standards for 2.54mm pitch connectors. The series includes various configurations for headers and sockets, accommodating different row counts and termination styles. The M20-876 variant specifically denotes a surface mount header with shroud-less design, widely used in industrial and consumer electronics for robust interconnect solutions.

Replacement Considerations

Compatible substitutes within the same series include M20-8760442 (8-position) and M20-8761042P (20-position). These parts share identical pitch, mounting style, and material specifications, allowing for functional interchangeability if the position count aligns with the application requirements.
