M50-4901145

Headers, Male Pins Overview

The M50-4901145 is a shrouded, double in-line (DIL) surface-mount header from the Harwin Archer M50 series. It features a 1.27 mm pitch and two rows of contacts, providing a total of 22 positions. The connector utilizes gold-plated phosphor bronze pins housed in a black liquid crystal polymer (LCP) body, rated for UL 94 V-0 flammability. Designed for vertical SMT installation, it supports a current rating of 1 A and operates within a temperature range of -40°C to +105°C. The component includes mounting pegs for secure placement during assembly.

Headers, Male Pins Feature Summary

• Shrouded four-wall design ensures precise mating alignment and protects against solder bridging.
• Surface-mount termination with integrated mounting pegs facilitates automated pick-and-place manufacturing.
• High-performance LCP housing provides dimensional stability and meets UL 94 V-0 fire safety standards.

Headers, Male Pins Applications

• High-density board-to-board interconnections
• Automotive electronic control units
• Industrial communication modules

Headers, Male Pins Procurement Notes

Verify the specific suffix '45' confirms the standard tube packaging format rather than tape-and-reel configuration. Ensure compatibility with the corresponding socket or header pair within the Archer M50 ecosystem. Confirm that the gold plating thickness meets the required cycle life specifications for the intended application environment.

Headers, Male Pins Selection Notes

Select this component when a low-profile, high-reliability surface-mount solution is required for dense circuit layouts. The 1.27 mm pitch offers a balance between pin count and spacing. Consider the shrouded design if lateral misalignment protection is critical for the assembly process.

Headers, Male Pins Part Context

This part belongs to the Archer M50 family, known for robust performance in demanding environments. The series offers various configurations including through-hole and IDC options, but this specific model is optimized for SMT processes. It complements other M50 components to create complete interconnection systems.

Headers, Male Pins Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the 1.27 mm pitch, 22-position DIL configuration, and SMT mounting style.
