Frequently Asked Questions
What contact material and finish does the Harwin M22-6550642R use, and how does this affect soldering?
The M22-6550642R uses phosphor bronze contacts with a tin (Sn) finish over a nickel (Ni) barrier layer. This combination provides excellent solderability during wave or hand soldering at temperatures up to 260°C, while the nickel barrier prevents tin migration and maintains reliable contact resistance below 30 mΩ over the connector's operating lifetime.
What are the body dimensions of the M22-6550642R and how do they fit into a dense PCB layout?
The M22-6550642R measures 0.484" (12.3 mm) in length, 0.157" (4 mm) in breadth, and 0.49" (12.5 mm) in depth. This compact footprint fits within tight PCB zones on embedded controller boards, allowing multiple connectors to be placed within a 25 mm x 25 mm board section without violating 2.54 mm pitch clearance rules.
Is the Harwin M22-6550642R RoHS compliant, and can it be used in lead-free PCB assembly processes?
Yes. The M22-6550642R carries a Pb-free (RoHS-compliant) designation, meaning it is compatible with lead-free solder alloys such as SAC305 (Sn-Ag-Cu) used in reflow and wave soldering at peak temperatures up to 260°C. The tin-over-nickel contact finish is fully compatible with standard lead-free PCB assembly processes used in European and Asian markets.
What mating connector from the Harwin M22-series pairs with the M22-6550642R female board connector?
The M22-6550642R female connector is designed to mate with corresponding Harwin M22-series male header pins at a 0.100" (2.54 mm) pitch. The M22 series offers polarized and un-polarized male header options in matching 6-position dual-row configurations, providing a secure board-to-board stack with a typical insertion force of 3 N to 5 N per pin position.
