M50-4703345

Headers, Male Pins Overview

The M50-4703345 is a vertical pin header from the Harwin ARCHER series, designed for board-to-board connections. It features a 1.27 mm pitch and a dual-row configuration with 66 positions (33+33). The connector utilizes gold-plated phosphor bronze contacts housed in a black thermoplastic body rated UL 94 V-0. It supports through-hole solder termination and operates within a temperature range of -40°C to +105°C, with a current rating of 1 A and voltage rating of 250 V.

Headers, Male Pins Feature Summary

• Vertical pin header design for direct PCB mounting
• Gold-plated phosphor bronze contacts for reliable conductivity
• UL 94 V-0 rated thermoplastic housing material
• Dual-row architecture supporting high-density interconnects

Headers, Male Pins Applications

• High-density board-to-board interconnections
• Industrial control system backplanes
• Telecommunications equipment signal routing
• Automotive electronic module interfaces

Headers, Male Pins Procurement Notes

Verify the specific contact plating thickness and housing material grade against the official datasheet before procurement. Ensure that the through-hole soldering profile matches the thermal specifications of the thermoplastic housing to prevent deformation during assembly processes.

Headers, Male Pins Selection Notes

Select this component when a vertical, non-shrouded header is required for dense signal routing. Consider the 1.27 mm pitch constraint and the 1 A current limit per contact. Verify compatibility with mating socket assemblies within the same ARCHER series family for proper mechanical engagement.

Headers, Male Pins Part Context

This part belongs to the ARCHER M50 series, a comprehensive line of connectors known for their compact form factor and robust electrical performance. The series offers various row counts and termination styles, providing engineers with flexible options for diverse PCB layout requirements and space-constrained applications.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Harwin ARCHER series headers with identical 1.27 mm pitch, 66-position count, and vertical orientation. Cross-manufacturer replacements require matching pitch, row configuration, and contact material specifications to ensure functional equivalence.
