Frequently Asked Questions
What contact plating specification does the SQT-105-01-L-D use, and how many mating cycles does it support?
The SQT-105-01-L-D uses gold (10 µin) over nickel (50 µin) contact plating, which provides corrosion resistance and maintains low contact resistance below 20 mΩ across a rated mating cycle life typically exceeding 500 insertion cycles. The gold finish is especially important in environments with humidity or light oxidation exposure, where tin or bare-copper contacts would degrade electrical performance in 2.00 mm pitch board-to-board socket applications.
For a removable daughter-card design, how does the 2.00 mm pitch of the SQT-105-01-L-D compare to standard 2.54 mm pitch connectors in terms of board space savings?
At 2.00 mm pitch versus the standard 2.54 mm pitch, the SQT-105-01-L-D reduces connector centerline spacing by 0.54 mm per contact pair, saving approximately 21% of connector-occupied board width for a 10-position dual-row socket. In a 10-position dual-row configuration spanning 20 contacts, this translates to a board length saving of over 5 mm compared to a 2.54 mm pitch equivalent, enabling more compact daughter-card and module designs.
What lead time and procurement advantage does the SAMTEC FLEXYZ Tiger Buy designation provide for the SQT-105-01-L-D?
The FLEXYZ Tiger Buy designation means the SQT-105-01-L-D is stocked by SAMTEC for rapid order fulfillment with a factory lead time of 1 week, significantly shorter than the 8–16 week lead times typical for custom or non-stocked connector variants. This availability is critical for prototype builds, production ramp-ups, and repair orders in industrial and embedded applications where supply chain delays for 2.00 mm pitch connectors could halt manufacturing.
Which rugged industrial or embedded computing applications benefit most from the SQT-105-01-L-D's dual-row socket construction?
The dual-row socket construction of the SQT-105-01-L-D provides mechanical stability and redundant contact retention suited for industrial PLCs, robotics controller boards, FPGA development modules, test fixture motherboards, and ruggedized embedded computers. Dual-row 2.00 mm pitch sockets distribute mating forces across 10 contact pairs on both rows, reducing individual contact stress during vibration and repeated insertion events common in factory automation and military electronics environments.
