Applications
The SFM-103-L2-SM-D-A is well suited for board-to-board stacking in test and measurement equipment, where its 0.050" pitch dual-row design provides reliable 6-pin signal connections in a compact footprint. It is also used in embedded computing modules and RF development boards where high-density SMD connectors with consistent mating forces are required. Industrial and aerospace applications leverage this part for its high-reliability contact system that maintains signal integrity across repeated mating cycles.

Frequently Asked Questions
What is the pitch and row configuration of SFM-103-L2-SM-D-A and how does it compare to single-row alternatives?
The SFM-103-L2-SM-D-A has a 0.050" (1.27mm) pitch in a dual-row configuration providing 6 positions total (3 per row). Compared to single-row 0.050" strips, the dual-row format doubles signal density in the same board footprint length, making it preferable for designs needing 6 contacts in minimal PCB space under 6.35mm board length.
Which SMT assembly processes are compatible with SFM-103-L2-SM-D-A for production board manufacturing?
The SFM-103-L2-SM-D-A surface-mount termination style is compatible with standard reflow soldering at typical solder paste temperatures of 230°C to 260°C peak. Automated pick-and-place equipment handles this component using the 6-position body. SAMTEC specifies the L2 tail length option for this SMD variant, which sets the solder pad land pattern dimensions for PCB footprint design at 0.050" (1.27mm) grid.
For a modular embedded computing card edge, when should SFM-103-L2-SM-D-A be selected over SAMTEC SSM series?
Select SFM-103-L2-SM-D-A when the design requires a surface-mount 6-position dual-row receptacle at 0.050" pitch with the A (vertical) orientation. The SSM series provides through-hole mounting, while SFM is the SMD equivalent. For embedded PC/104 or mezzanine cards needing low-profile SMD socket connections at 1.27mm pitch with 6 positions, SFM-103 is the correct SAMTEC family.
How many mating cycles is SFM-103-L2-SM-D-A rated for and what contact plating is used?
SAMTEC SFM series high-reliability socket strips are rated for a minimum of 50 mating cycles with gold-plated contact surfaces. The 6-position dual-row design uses precision-formed beryllium copper or phosphor bronze contacts with gold plating to maintain low contact resistance below 20 milliohms even after repeated insertions in test fixtures or removable module applications.
