M50-3550542

Headers, Male Pins Overview

The M50-3550542 is a male pin header from the Harwin ARCHER series, designed for board-to-board or cable connections. It features a 1.27 mm (0.05 in) pitch with 10 positions arranged in a double inline (DIL) configuration across two rows. The connector utilizes a vertical through-hole mounting style with solder termination. Contact surfaces are gold-plated phosphor bronze, rated for 1 A current. The housing is constructed from black liquid crystal polymer (LCP), offering UL 94 V-0 flammability ratings and an operating temperature range of -40°C to +105°C.

Headers, Male Pins Feature Summary

• Vertical through-hole mounting design for secure PCB integration
• Gold-plated contacts ensure reliable signal transmission
• High-temperature resistant LCP housing material
• Integrated latch mechanism for mating stability

Headers, Male Pins Applications

• Industrial control system interconnects
• Automotive electronic module connections
• Consumer device internal circuit boards
• Telecommunications equipment backplanes

Headers, Male Pins Procurement Notes

Verify that the specific part number matches the required 10-position DIL configuration and vertical orientation. Confirm that the gold plating specification aligns with environmental requirements. Ensure compatibility with mating sockets within the ARCHER series. Check for any specific RoHS compliance documentation if required by regional regulations. Validate that the through-hole soldering process parameters are suitable for the component's thermal characteristics.

Headers, Male Pins Selection Notes

Select this component when a low-profile, high-density connection is needed with robust mechanical latching. The 1.27 mm pitch allows for compact circuit layouts compared to standard 2.54 mm headers. Consider the gold contact plating for applications requiring corrosion resistance and low contact impedance. The vertical form factor simplifies assembly on single-sided boards or where space above the PCB is limited. Evaluate the thermal rating against the operational environment.

Headers, Male Pins Part Context

This part belongs to the Harwin ARCHER M50 family, known for its modular design and wide variety of mating heights. The series supports both surface mount and through-hole technologies. The M50-3550542 specifically addresses needs for small-form-factor connectors with high reliability. It complements other ARCHER components like cable connectors and sockets to create complete interconnect solutions.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 1.27 mm pitch, 10-position count, and vertical through-hole format. Verify that alternative headers maintain similar current ratings and temperature specifications. Ensure physical dimensions, including height and latch placement, fit within the enclosure constraints. Cross-reference with other manufacturers' equivalent DIL headers if supply chain issues arise.
