MK LP 43 42 G

Headers, Male Pins Overview

The MK LP 43 42 G is a male pin header connector manufactured by Fischer Elektronik. It features a through-hole mounting style with 42 positions arranged in a single row. The contact pitch spacing is 0.100 inches (2.54 mm). The insulation material is polyamide (PA46), glass-filled nylon, rated UL94 V-0 for flammability. The operating temperature range spans from -40°C to 163°C. Contact material is brass, and the connector is designed for board-to-board or wire-to-board applications.

Headers, Male Pins Feature Summary

• Low profile design suitable for space-constrained PCB layouts
• Single row configuration with 42 contacts for high-density interconnects
• Through-hole termination method ensures secure mechanical attachment
• Glass-filled polyamide insulation provides structural stability and thermal resistance

Headers, Male Pins Applications

• Board-to-board connections in industrial control systems
• Wire-to-board interfaces in consumer electronics assemblies
• Signal routing in telecommunications equipment
• Interconnection modules in automotive electronic subsystems

Headers, Male Pins Procurement Notes

Verify that the specific part number matches the required 42-position count and single-row layout. Confirm compatibility with standard 2.54 mm pitch mating connectors. Ensure the through-hole footprint aligns with your PCB design guidelines. Check that the polyamide insulation rating meets your environmental requirements. Validate that the operating temperature range covers your application's thermal conditions before finalizing procurement.

Headers, Male Pins Selection Notes

Choose this component when a low-profile, single-row header is needed for reliable signal transmission. The 42-contact capacity supports complex circuitry without increasing board area significantly. The through-hole installation offers robust mechanical strength compared to surface-mount alternatives. Consider the thermal performance of the PA46 insulation if the environment exceeds standard temperatures. Ensure mating connectors match the 2.54 mm pitch specification for proper alignment and contact integrity.

Headers, Male Pins Part Context

This connector belongs to Fischer Elektronik's MK LP series, which focuses on low-profile solutions for modern electronics. The series emphasizes compactness while maintaining electrical reliability. The 42-position variant provides a balance between connectivity density and physical size. It complements other headers in the lineup by offering a standardized pitch and durable construction. The design supports automated assembly processes common in mass production environments.

Headers, Male Pins Replacement Considerations

Direct substitutes must maintain the 42-position count, 2.54 mm pitch, and single-row through-hole format. Verify that alternative manufacturers offer compatible insulation materials and temperature ratings. Ensure mechanical dimensions match the original footprint to avoid PCB redesign. Cross-reference contact plating specifications if corrosion resistance is critical. Confirm that the replacement part meets the same UL94 V-0 flammability standards.
