What are the key features of QTT-117-01-L-T?
- 51 positions at 2.00 mm pitch supporting both signal and power distribution in a single board stack
- Gold (10 µin) over nickel contact finish on mating surfaces for reliable low-resistance connections
- Phosphor bronze contacts deliver strong spring force and durability across repeated mating cycles
- Board stacking (QTT) architecture with defined stack height for precise mechanical alignment
- Tape packaging (T suffix) for automated SMT production and pick-and-place compatibility
- Lead-free (Pb-free) construction with tin-over-nickel termination finish for RoHS compliance
What is QTT-117-01-L-T used for?
QTT-117-01-L-T is designed for power plane interconnect and high-density signal routing in stacked PCB assemblies such as compute module carrier boards, FPGA mezzanine cards, and industrial backplane systems. Its 51-position 2.00 mm pitch layout is suited for applications that must distribute both logic signals and power rails across two vertically stacked boards while maintaining board-to-board mechanical rigidity.

Frequently Asked Questions
How does the 2.00 mm pitch of QTT-117-01-L-T compare to 2.54 mm pitch alternatives for power plane board stacking?
At 2.00 mm pitch, QTT-117-01-L-T provides 51 positions across a board span of approximately 102 mm, roughly 20% more compact than an equivalent 2.54 mm pitch connector carrying the same position count. This tighter pitch benefits high-density backplanes where reducing connector real estate is critical without sacrificing power-plane contact count.
What contact finish does QTT-117-01-L-T use on its mating surfaces, and why does that matter for long service life?
QTT-117-01-L-T uses gold (10 µin minimum) over nickel on the mating contact surfaces. Gold plating prevents oxidation and maintains low milliohm contact resistance across hundreds of insertion and extraction cycles, which is particularly valuable in board stacking systems that may be re-mated during field maintenance or module upgrades.
For an industrial control backplane running at 5V and 3.3V rails, how many positions can be allocated to power versus signal in QTT-117-01-L-T?
QTT-117-01-L-T provides 51 total positions, giving a board designer flexibility to assign dedicated power contacts—typically rated at 1 A to 3 A per contact depending on derating—alongside signal positions within the same 2.00 mm pitch connector row. This mixed power-and-signal capability reduces the total number of connectors on a backplane design.
How is QTT-117-01-L-T supplied for production, and what termination finish is on the PCB solder tails?
QTT-117-01-L-T ships in tape packaging (T suffix) for automated pick-and-place assembly. The PCB termination finish is tin (Sn) over a nickel (Ni) barrier, which is compatible with standard lead-free solder paste and reflow profiles at typical peak temperatures of 260°C, ensuring reliable solder joint formation on the board pads.
