M50-3904942

Headers, Male Pins Overview

The Harwin M50-3904942 is a board-to-board connector from the Archer M50 series, featuring a 1.27 mm pitch and a right-angle male header configuration. It comprises 98 contacts arranged in two rows with solder pin terminals for through-hole mounting. The insulator is constructed from black thermoplastic material, and the contacts utilize a tin-nickel barrier finish. Designed for high-density applications, it supports a dielectric withstand voltage of 1000VAC and offers a mechanical durability rating of 300 mating cycles.

Headers, Male Pins Feature Summary

• Right-angle male header design facilitates compact vertical board stacking
• Dual-row 98-contact arrangement enables high-density signal routing
• Through-hole solder pin termination ensures robust PCB attachment

Headers, Male Pins Applications

• High-density board-to-board interconnections
• Vertical circuit board stacking assemblies
• Industrial control system backplanes

Headers, Male Pins Procurement Notes

Verify the specific contact count and orientation against project requirements, as the M50 series offers various configurations. Confirm that the right-angle through-hole mounting style aligns with the PCB layout constraints. Ensure the tin-nickel terminal finish meets the environmental and soldering process specifications for the target assembly.

Headers, Male Pins Selection Notes

Select this component when a high-pin-count, right-angle male header is required for rigid board-to-board connections. The 1.27 mm pitch suits dense layouts, while the through-hole option provides mechanical stability. Consider the 1000VAC dielectric rating for insulation needs and verify compatibility with the mating female receptacle within the same M50 series family.

Headers, Male Pins Part Context

This part belongs to the Harwin Archer M50 series, designed for space-constrained electronic applications. The series emphasizes reliable performance in industrial environments through standardized 1.27 mm spacing. The M50-3904942 specifically addresses the need for high-channel count interconnects in a vertical form factor, supporting complex multi-layer board architectures.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other Harwin M50 series right-angle male headers with equivalent pin counts and pitch. Verify that alternative parts maintain the same 1.27 mm spacing and through-hole termination style to ensure mechanical and electrical interchangeability without redesigning the PCB footprint.
