MK LP 42 46 G

Headers, Male Pins Overview

The MK LP 42 46 G is a single-row male pin header manufactured by Fischer Elektronik, designed for board-to-board or wire-to-board interconnections. It features a 2.54 mm pitch spacing and accommodates 46 contacts. The connector utilizes copper-zinc alloy contacts with gold plating to ensure reliable signal transmission. Insulation is provided by glass-filled polyamide (PA46), rated UL94 V-0 for flame resistance. The component supports an operating temperature range of -40°C to 163°C and is rated for 3A current at 250VAC.

Headers, Male Pins Feature Summary

• Single-row configuration with 46 positions for high-density connectivity
• Gold-plated copper-zinc contacts for corrosion resistance and low contact resistance
• Glass-filled PA46 insulation material ensuring mechanical stability and flame retardancy

Headers, Male Pins Applications

• High-density electronic assemblies requiring robust signal routing
• Industrial control systems operating within extended temperature ranges
• Consumer electronics utilizing standard 2.54mm pitch interfaces

Headers, Male Pins Procurement Notes

Verify the specific contact surface finish details against the manufacturer's datasheet, as variations exist within the MK LP 42 series regarding nickel underplating thickness. Confirm that the single-row 46-position configuration matches the PCB footprint requirements. Ensure compatibility with mating connectors using standard 2.54 mm headers. Check for any specific RoHS compliance documentation if required by the target market regulations.

Headers, Male Pins Selection Notes

Select this model when a single-row layout is preferred over dual-row designs to minimize profile height while maintaining high pin counts. The 2.54 mm pitch ensures broad compatibility with existing industry-standard cables and mating connectors. Consider the thermal rating of -40°C to 163°C for applications involving significant heat generation or extreme environmental conditions. Verify that the 3A current rating suffices for the intended circuit load.

Headers, Male Pins Part Context

This component belongs to the Fischer Elektronik MK LP 42 series, which specializes in low-profile pin headers. The series offers various contact counts and row configurations to suit different density needs. The MK LP 42 46 G specifically addresses applications requiring a long, single-row connection path without increasing the vertical space occupied by dual-row alternatives.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other single-row 2.54 mm pitch headers from manufacturers such as Samtec or Molex, provided they match the 46-contact count and similar current/voltage ratings. Ensure the replacement part maintains the same insulation material properties and temperature rating to preserve system reliability.
