M50-3904142

Headers, Male Pins Overview

The Harwin M50-3904142 is a rectangular connector header from the Archer M50 series, designed for board-to-board or cable-to-board applications. It features a 1.27 mm (0.05 in) pitch with a dual inline configuration of 40 positions. The component utilizes through-hole termination with solder pins and operates at a rated voltage of 600 V and current of 1 A. Constructed with phosphor bronze contacts featuring gold plating and a black polybutylene terephthalate (PBT) housing, it supports a temperature range of -40°C to +105°C.

Headers, Male Pins Feature Summary

• Gold-plated phosphor bronze contacts ensure reliable signal transmission and corrosion resistance
• High voltage rating of 600 V accommodates demanding power and signal requirements
• Through-hole solder pin termination facilitates secure mechanical attachment to printed circuit boards

Headers, Male Pins Applications

• Industrial control systems requiring high-density interconnects
• Consumer electronics utilizing board-to-board connections
• Telecommunications equipment needing reliable signal routing
• Automotive electronic modules with space constraints

Headers, Male Pins Procurement Notes

Verify that the specific part number matches the required 40-position dual inline configuration and 1.27 mm pitch before ordering. Confirm compatibility with existing PCB footprints and mating connectors within the Archer M50 series. Ensure environmental conditions align with the specified operating temperature range and voltage ratings. Check for RoHS compliance documentation if required by project specifications.

Headers, Male Pins Selection Notes

Select this component when a high-voltage, dual-row header is necessary for dense circuit layouts. The 1.27 mm pitch allows for significant I/O density compared to larger spacing options. Consider the through-hole mounting style for robust mechanical stability during assembly. Evaluate the gold contact plating against cost-sensitive alternatives if extreme durability is not critical.

Headers, Male Pins Part Context

This connector belongs to the Harwin Archer M50 family, known for its low-profile design and high reliability. The series offers various configurations including surface mount and different row counts. The M50-3904142 specifically addresses needs for horizontal through-hole headers with substantial current and voltage handling capabilities in a standard rectangular form factor.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other Harwin M50 series headers with matching 40-position dual inline layouts and 1.27 mm pitch. Verify that alternative parts maintain identical voltage, current, and temperature specifications. Ensure mechanical dimensions and pin configurations are compatible with existing PCB designs and mating components.
