MK LP 43 21 Z

Headers, Male Pins Overview

The MK LP 43 21 Z is a male pin header connector from Fischer Elektronik, designed for through-hole PCB mounting. It features 21 positions with a 0.100-inch (2.54 mm) pitch and a 0.100-inch row spacing. The connector utilizes brass contacts with gold plating on the mating interface and tin plating on the pins. Rated for 3A current and 150V DC, it operates within a temperature range of -40°C to +163°C. The housing is black, constructed from material rated UL94 V-0 for flammability.

Headers, Male Pins Feature Summary

• Low profile design optimized for space-constrained electronic assemblies
• Gold-plated contact surfaces ensure reliable signal transmission and corrosion resistance
• Through-hole termination provides secure mechanical attachment to printed circuit boards

Headers, Male Pins Applications

• General purpose interconnects in consumer electronics
• Industrial control system wiring harnesses
• Embedded module connections in computing hardware

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact count and plating specifications. Ensure compatibility with existing PCB footprint dimensions and soldering profiles. Cross-reference the part number with authorized distributors to confirm availability and authenticity. Check for any recent updates to the component's environmental compliance status or mechanical tolerances before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a low-profile male header with 21 positions is required for through-hole assembly. Consider the 2.54 mm pitch standard for broad compatibility with mating connectors. Evaluate the thermal operating range and current rating against the application's electrical load requirements. Confirm that the UL94 V-0 insulation rating meets safety standards for the intended enclosure environment.

Headers, Male Pins Part Context

This part belongs to the MK LP 43 series of low-profile pin headers manufactured by Fischer Elektronik. The series offers various position counts while maintaining consistent mechanical and electrical characteristics. These connectors are engineered for robust performance in standard electronic manufacturing processes, providing a reliable solution for board-to-board or cable-to-board connections.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Fischer Elektronik MK LP 43 series variants with matching pin counts, such as the MK LP 43 20 Z or MK LP 43 22 G, provided the exact position count aligns with the design. Verify that alternative suppliers offer components with identical pitch, height, and plating specifications to ensure mechanical fit and electrical continuity without redesigning the PCB layout.
