Frequently Asked Questions
How many positions and rows does the SQT-105-03-F-D have, and what is its contact pitch?
The SQT-105-03-F-D is a dual-row socket connector with 5 contacts per row for a total of 10 positions, arranged on a 0.050 inch (1.27 mm) pitch. This compact pitch enables high-density interconnects on space-constrained PCBs, making it suitable for telecommunications, networking, and embedded computing boards where signal density is a priority.
What contact finish does SQT-105-03-F-D use, and why does it matter for signal reliability?
The SQT-105-03-F-D uses a gold-flash mating contact finish, which provides superior corrosion resistance and low contact resistance compared to tin-plated alternatives. Gold-flash contacts maintain reliable electrical connections across multiple mating cycles, making this connector appropriate for applications requiring stable signal integrity such as high-speed digital interfaces running at frequencies up to several hundred MHz.
What special contact technologies are featured in the SQT-105-03-F-D and how do they benefit assembly?
The SQT-105-03-F-D incorporates SAMTEC's FlexYZ and Tiger Buy contact technologies. FlexYZ contacts provide compliance in the Z-axis to accommodate board-level tolerances and reduce stress during mating, while Tiger Buy simplifies procurement. These features allow the connector to absorb up to several mils of misalignment, protecting solder joints in vibration-prone environments and reducing assembly rework rates.
Is the SQT-105-03-F-D RoHS compliant, and what lead time should procurement plan for?
Yes, the SQT-105-03-F-D is lead-free and RoHS compliant, confirmed by its Pbfree Code designation. Standard factory lead time is approximately 5 weeks for non-stocked quantities. For volume builds, procurement teams should factor in this 5-week lead time when planning BOM schedules, or verify stocked availability at authorized distributors to support just-in-time manufacturing programs.
