Frequently Asked Questions
What contact material and mating finish does QTT-117-02-L-T use, and how do they affect current handling?
QTT-117-02-L-T uses phosphor bronze contacts with 10 µin gold over nickel on the mating surface. Phosphor bronze provides excellent spring-back force for consistent contact pressure across all 51 positions, while 10 µin gold resists oxidation, helping maintain low contact resistance over the connector's operating life in power plane stacking applications.
How does the 2.00 mm pitch of QTT-117-02-L-T support higher current per pin compared to fine-pitch alternatives?
At 2.00 mm pitch, each pin in QTT-117-02-L-T occupies more PCB pad space than 1.27 mm pitch connectors, allowing a larger contact cross-section. This enables each contact to carry higher current, typically in the range of 3 A to 6 A per pin, making the 51-position strip capable of distributing aggregate power loads across multiple power plane connections in stacked board designs.
In what types of board stacking assemblies does the QTT-117-02-L-T body size fit best?
With a body length of 1.353 inches, breadth of 0.236 inch, and depth of 0.355 inch, QTT-117-02-L-T fits in mid-size board stacking assemblies such as SBC carrier boards, industrial I/O expansion cards, and multi-layer telecom shelf units. Engineers should verify the 0.355-inch depth clears any SMT components within the stack-height envelope.
How should engineers verify QTT-117-02-L-T RoHS compliance status for export documentation?
SAMTEC lists QTT-117-02-L-T as Pbfree Code Yes, meaning it is manufactured without intentionally added lead, cadmium, mercury, or other restricted substances under EU RoHS Directive 2011/65/EU. For formal export or customer compliance documentation, request a RoHS certificate of conformance from SAMTEC's distribution channel, specifying the part number and date code of the shipped lot.
