MK LP 42 45 Z

Headers, Male Pins Overview

The MK LP 42 45 Z is a low-profile male pin header connector manufactured by Fischer Elektronik. It features 45 positions with a 0.100-inch (2.54mm) pitch spacing and through-hole mounting. The connector utilizes brass contact material with tin-plated surfaces, offering a volume resistance of ≤10 mΩ. It supports a maximum current of 3A at 150VDC. The insulating body is made of PA 4.6 GF, rated UL94 V-0, operating within -40°C to +163°C. Mechanical resilience includes shock resistance up to 50g and vibration resistance up to 15g.

Headers, Male Pins Feature Summary

• Low-profile design for space-constrained applications
• Tin-plated contact surface for reliable conductivity
• High mechanical stability with defined shock and vibration resistance ratings

Headers, Male Pins Applications

• General-purpose PCB interconnections
• Industrial control systems requiring robust headers
• Consumer electronics assembly

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix against the official Fischer Elektronik datasheet to ensure correct contact plating and insulation material specifications. Confirm that the 45-position configuration matches the target PCB footprint requirements. Cross-reference the thermal rating with soldering process limits to prevent damage during reflow or wave soldering operations.

Headers, Male Pins Selection Notes

Select this component when a low-profile male header with high mechanical durability is required. Ensure the application environment stays within the specified temperature range of -40°C to +163°C. Verify that the 2.54mm pitch aligns with mating connector standards. Consider the tin-plated finish for general use rather than high-corrosion environments unless protected.

Headers, Male Pins Part Context

This part belongs to the MK LP 42 series of low-profile pin headers from Fischer Elektronik. The series offers various position counts, including 25, 30, and 45 contacts. These connectors are designed for through-hole mounting on printed circuit boards, providing stable electrical connections in compact electronic assemblies.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Fischer Elektronik MK LP 42 variants with different pin counts, such as MK LP 42 30 Z or MK LP 42 25 Z, provided the board layout allows for fewer positions. Generic 2.54mm pitch headers may fit mechanically but must be verified for matching height and mechanical strength specifications.
