Frequently Asked Questions
How many positions and what pitch does SQW-125-01-L-D-VS-K offer for high-density board interconnects?
The SQW-125-01-L-D-VS-K is a 50-position dual-row socket with a 2.00 mm pitch, providing 25 contacts per row in a 1.98 inch long body. This combination of moderate pitch and high pin count is well-suited for industrial I/O expansion boards, computing module sockets, and communication system backplane interconnects requiring reliable multi-channel signal routing.
What contact finish does SQW-125-01-L-D-VS-K use and how does it compare to standard tin-finished connectors?
The SQW-125-01-L-D-VS-K uses 10 micro-inch gold (Au) on the mating contact surfaces with a Nickel (Ni) barrier, and Tin (Sn) with Nickel barrier on the termination side. Gold mating contacts provide significantly lower contact resistance and better corrosion resistance than standard matte tin alternatives, making this socket more reliable in environments with moderate humidity or where long-term connection integrity is required.
What does the Tiger Buy contact technology in SQW-125-01-L-D-VS-K mean for procurement and reliability?
SAMTEC's Tiger Buy designation indicates that the SQW-125-01-L-D-VS-K is available in higher stock quantities at competitive pricing, making it a cost-effective choice for medium to high volume production runs. Despite the cost-optimized pricing, the connector still uses 10 micro-inch gold mating contacts and a rugged socket body with a 2.00 mm pitch, maintaining the electrical and mechanical reliability needed for industrial and commercial electronics applications.
Is SQW-125-01-L-D-VS-K suitable for vertical SMT assembly, and what is its board footprint?
Yes, the SQW-125-01-L-D-VS-K features a vertical surface mount (VS) orientation and is designed for standard SMT reflow assembly. The 50-position dual-row body measures 1.98 inch in length and 0.157 inch in breadth, providing a well-defined PCB footprint for automated pick-and-place placement. The 2.00 mm pitch ensures adequate contact spacing for reliable solder joint formation during reflow processing.
