MK LP 41 40 G

Headers, Male Pins Overview

The Fischer Elektronik MK LP 41 40 G is a through-hole male pin header connector featuring 40 positions with a 2.54 mm (0.100 inch) pitch. Constructed for board-to-board or wire-to-board applications, it utilizes a tin-plated contact surface and a contact sleeve with a nickel layer of 4 to 6 µm. The component operates within a temperature range of -40°C to +163°C and withstands soldering at 260°C for 10 seconds. It complies with RoHS standards and is designed for reliable electrical interconnection in electronic assemblies.

Headers, Male Pins Feature Summary

• Low profile design suitable for space-constrained PCB layouts
• Tin-plated contact surfaces ensure reliable conductivity
• Nickel underlayer on contact sleeves provides mechanical stability

Headers, Male Pins Applications

• Board-to-board interconnections
• Wire-to-board connections
• General electronic assembly integration

Headers, Male Pins Procurement Notes

Verify the specific plating configuration against official datasheets, as variants exist with different finishes such as gold or thick tin. Confirm that the 40-position count matches the required circuit density. Ensure compatibility with standard 2.54 mm grid spacing on target PCBs. Check for any specific handling requirements related to the low-profile form factor during automated assembly processes.

Headers, Male Pins Selection Notes

Select this model when a 40-way connection is required in a compact footprint. The 2.54 mm pitch ensures broad compatibility with existing headers and sockets. Consider the operating temperature limits and soldering thermal profiles to ensure integrity during reflow. Evaluate if the low-profile height meets clearance constraints compared to standard-height alternatives.

Headers, Male Pins Part Context

This component belongs to the MK LP 41 series of low-profile male pin headers from Fischer Elektronik. The series offers various position counts while maintaining consistent 2.54 mm pitch and structural characteristics. It serves as a standard interconnect solution for general-purpose electronics manufacturing.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other 40-position, 2.54 mm pitch through-hole headers from manufacturers such as Samtec or Molex, provided they match the low-profile dimensions and current ratings. Verify that alternative parts support the same soldering thermal profile and environmental specifications.
