Key Features
- 62 positions in dual-row 0.050" (1.27 mm) pitch for maximum signal density in compact PCB layouts
- T2 tail length with kinked (K) tails providing optimal pad contact and solder joint stability during reflow
- High-reliability socket construction rated for extended mating cycles with gold-plated contacts
- Surface mount design enabling component placement on both PCB sides without through-hole drilling
Applications
The SFM-131-T2-S-D-A-K is engineered for high-density FPGA mezzanine cards, multi-gigabit backplane interfaces, and data acquisition modules requiring 62-position dual-row 0.050" pitch socket connectivity. Its high-reliability construction supports demanding defense, aerospace, and telecommunications applications where signal integrity across all 62 channels must be maintained through thousands of mating cycles. The surface mount format with kinked tails ensures mechanical and electrical stability through standard lead-free SMT reflow processes.

Frequently Asked Questions
What signal density advantage does the SFM-131-T2-S-D-A-K provide over 0.100" pitch alternatives?
At 0.050" (1.27 mm) pitch, the SFM-131-T2-S-D-A-K accommodates 62 positions in roughly the same PCB length as a 31-position 0.100" connector, doubling contact density. For FPGA I/O expansion headers and high-speed bus interfaces, this means more signal lines—including differential pairs and ground shields—fit within the same board real estate with no increase in footprint area.
How many mating cycles is the SFM-131-T2-S-D-A-K rated for and what applications require that durability?
SAMTEC SFM high-reliability socket strips are typically rated for a minimum of 200 to 500 mating cycles with gold-plated contacts maintaining contact resistance below 20 milliohms. This durability suits test fixtures, removable mezzanine cards in laboratory instruments, and field-upgradeable modules in telecommunications systems where the 62-position connector is connected and disconnected frequently over the product's service life.
Which mating headers pair with SFM-131-T2-S-D-A-K for a board-to-board stack application?
The SFM-131-T2-S-D-A-K mates with SAMTEC TSM-131-series and compatible SFM-series headers at the same 0.050" dual-row pitch, providing a 62-position plug-and-socket pair. Stack height between PCBs depends on the header tail length selected, ranging from approximately 4 mm to over 10 mm, allowing designers to specify precise inter-board spacing for their chassis layout.
How do the kinked tails on SFM-131-T2-S-D-A-K help during SMT assembly of a 62-position connector?
Kinked (K) tails have a mechanical deformation that creates a pre-load spring force against the PCB pad, typically 80 to 120 grams per pin. For a 62-position connector, this aggregate force across all tails holds the socket firmly in place during solder paste printing and reflow, preventing the connector from shifting or floating on the molten solder and ensuring all 62 contacts land on their intended pads.
