Frequently Asked Questions
What is the contact pitch, pin count per row, and mating cycle rating of the SFM-122-T2-STL-D-A-K?
The SFM-122-T2-STL-D-A-K features a 0.050" (1.27 mm) pitch with 44 total positions arranged as 22 pins per row in a dual-row configuration. Gold-plated contacts are rated for over 1000 mating cycles, ensuring reliable performance in high-cycle test environments and field-serviceable board-to-board assemblies operating from -55°C to +125°C.
What does the STL designation mean in SFM-122-T2-STL-D-A-K and how does it affect PCB layout?
The STL designation in SFM-122-T2-STL-D-A-K indicates a stackthrough lead style where the SMT contact tails pass through the PCB, providing additional mechanical retention in surface mount applications. This hybrid through-hole anchoring combined with SMT soldering increases pull strength by approximately 30-50% compared to pure SMT versions, benefiting high-vibration aerospace and industrial applications. The footprint requires standard 0.050" pitch dual-row SMT land pattern with 44 pads.
Which SAMTEC mating connector series is compatible with SFM-122-T2-STL-D-A-K for board stacking applications?
The SFM-122-T2-STL-D-A-K is designed to mate with SAMTEC's TMM and SHF series headers using the same 0.050" (1.27 mm) pitch. Board separation (stack height) options range from 8 mm to 20 mm depending on the mating header height selected, routing 44 differential or single-ended signals between stacked boards in FPGA carrier systems, RF signal processing modules, and embedded computing platforms.
For what volume purchase ranges is SFM-122-T2-STL-D-A-K available and what lead times apply?
SAMTEC SFM-122-T2-STL-D-A-K is available through Mouser Electronics, Digi-Key, and Arrow distributors with typical lead times of 8-14 weeks for non-stocked quantities. Sample quantities of 5-10 pieces are available directly from SAMTEC with 1-2 week lead times for engineering evaluation. Volume pricing breaks typically occur at 50, 250, and 1000 unit quantities for production procurement planning.
