MK LP 43 4 G

Headers, Male Pins Overview

The Fischer Elektronik MK LP 43 4 G is a low-profile male pin header connector designed for surface-mount or through-hole applications. It features four contacts with a 2.54 mm pitch and operates within a temperature range of -40°C to +105°C. The housing is constructed from polyamide (PA46), glass-filled, ensuring UL94 V-0 flammability rating. Contacts are made of copper zinc alloy, plated with tin on the post and gold on the mating interface to ensure reliable electrical performance.

Headers, Male Pins Feature Summary

• Low-profile design optimized for space-constrained PCB layouts
• Gold-plated contact surfaces for enhanced conductivity and corrosion resistance
• Glass-filled polyamide insulation providing high thermal stability
• UL94 V-0 rated material for improved fire safety compliance

Headers, Male Pins Applications

• Industrial control systems requiring compact interconnects
• Consumer electronics with strict height limitations
• Automotive electronic modules needing reliable signal transmission
• Telecommunications equipment utilizing board-to-board connections

Headers, Male Pins Procurement Notes

Verify that the specific order matches the MK LP 43 4 G designation, as Fischer Elektronik offers various pin counts within this series. Confirm whether the required configuration supports through-hole or surface-mount installation based on the specific variant ordered. Ensure compatibility with standard 2.54 mm pitch footprints during procurement planning.

Headers, Male Pins Selection Notes

Select this component when a low-height profile is critical for assembly constraints. The gold-plated contacts make it suitable for environments where oxidation resistance is necessary. Verify that the operating temperature range meets the application's thermal requirements, particularly noting the PA46 insulation properties.

Headers, Male Pins Part Context

This part belongs to the MK LP 43 series, which provides low-profile solutions for dense PCB arrangements. The series includes multiple pin configurations, allowing designers to scale connectivity without changing the footprint style. It complements other Fischer Elektronik headers by offering consistent mechanical dimensions across different channel counts.

Headers, Male Pins Replacement Considerations

Direct substitutes include other MK LP 43 variants with different pin counts if the circuit design allows. Generic 2.54 mm pitch headers may serve as alternatives but often lack the specific low-profile geometry and UL94 V-0 certification. Verify cross-compatibility regarding housing color and contact plating thickness before substitution.
