What are the key features of SFM-117-L2-FM-D?
- 34 positions in dual-row 0.050 inch pitch configuration delivering high contact density per footprint
- High-reliability socket strip construction engineered for board-to-board mezzanine stacking applications
- Surface-mount termination enabling automated SMT assembly compatible with reflow soldering processes
- SAMTEC precision-stamped contacts ensuring consistent mating force and low contact resistance across 34 pins
What is SFM-117-L2-FM-D used for?
SFM-117-L2-FM-D is used in high-density mezzanine board-to-board interconnection systems such as daughter card interfaces on FPGA development boards, SOM (System-on-Module) carrier boards, and communication daughter cards requiring 34 pins at 0.050 inch pitch. The dual-row surface-mount format suits compact embedded computing modules where PCB height and footprint constraints demand fine-pitch connectors over traditional 0.100 inch headers. It is also applicable in test fixtures and evaluation platforms where reliable high-cycle mating is needed for development and validation.

Frequently Asked Questions
How many positions and what pitch does SFM-117-L2-FM-D provide for board-to-board mezzanine designs?
SFM-117-L2-FM-D offers 34 positions arranged in a dual-row format with 0.050 inch (1.27 mm) pitch. This configuration provides 17 contacts per row in a compact footprint, making it suitable for high-density daughter card interfaces where a standard 0.100 inch pitch single-row header would consume more than twice the PCB edge length to accommodate equivalent pin counts.
What are the assembly requirements for SFM-117-L2-FM-D in a surface-mount production line?
SFM-117-L2-FM-D is a surface-mount connector requiring standard SMT reflow soldering with a peak profile typically around 245°C to 260°C for lead-free processes, compatible with SAMTEC's specified land pattern at 0.050 inch pitch. The part is pick-and-place compatible and supplied in tape-and-reel format for automated assembly, with coplanarity and contact geometry optimized for reliable solder joint formation on standard FR4 PCBs.
Which SAMTEC mating header is compatible with the SFM-117-L2-FM-D socket strip?
The SFM-117-L2-FM-D socket mates with SAMTEC's TSM series or SFM-complementary header strips sharing the same 0.050 inch (1.27 mm) dual-row pitch and 34-position count, specifically designed for the SFM family. Using the matched SAMTEC header ensures controlled insertion force within the specified range of approximately 0.2 N to 0.5 N per contact and maintains the mated stack height within the nominal board separation tolerance.
For a compact SOM carrier board needing 34 signals at fine pitch, when is SFM-117-L2-FM-D preferred over a 0.100 inch connector?
SFM-117-L2-FM-D at 0.050 inch pitch reduces the connector footprint length by approximately 50% compared to a 0.100 inch dual-row header carrying the same 34 signals (from roughly 43 mm down to 22 mm), enabling denser PCB layouts in space-constrained modules under 50 mm × 50 mm. It is the preferred choice when board-to-board height stack must be minimized and signal count exceeds 20 pins, making full 0.100 inch alternatives impractical for the available edge length.
