What are the key features of SFM-119-L2-S-D-LC?
- 38-position dual-row socket on 0.050" (1.27 mm) pitch supports 19 signals per row for medium-density board-to-board interconnects
- Low-profile (L2) variant minimizes board stack height for space-constrained mezzanine assemblies
- Tiger Eye contact technology provides reliable wiping action and consistent contact resistance over repeated mating cycles
- Surface mount footprint compatible with standard SMT reflow processes for streamlined automated PCB assembly
What is SFM-119-L2-S-D-LC used for?
The SFM-119-L2-S-D-LC is designed for medium-density mezzanine board-to-board connections in industrial control modules, test and measurement instruments, and communications equipment requiring 38 reliable signal contacts. Its low-profile design is ideal for stacked PCB assemblies with tight vertical clearance, such as ruggedized embedded computing platforms. The 0.050" pitch enables high contact density while maintaining signal integrity for data rates found in modern digital interfaces.

Frequently Asked Questions
How does the L2 low-profile variant of SFM-119-L2-S-D-LC reduce board stack height compared to standard SFM parts?
The L2 designation in SFM-119-L2-S-D-LC indicates a lower-profile housing than the standard SFM series, reducing vertical stack height in mezzanine configurations. While the standard SFM body depth is approximately 0.185 inch, the L2 variant trims this dimension to support tight inter-board spacing of under 4 mm, making it suitable for ruggedized enclosures and compact embedded system stacks.
For a 38-signal dual-row interface, how does SFM-119-L2-S-D-LC distribute pins across rows?
The SFM-119-L2-S-D-LC has 38 total positions arranged in 2 rows, providing 19 pins per row on a 0.050" (1.27 mm) pitch. The body spans approximately 24 mm (19 positions × 1.27 mm). This layout accommodates mixed signal and power assignments across both rows, which is common in FPGA daughter cards and high-speed digital interface modules.
When is SFM-119-L2-S-D-LC preferred over a higher-position SFM such as SFM-140 for cost-sensitive designs?
The SFM-119-L2-S-D-LC is preferred when the design requires only 38 signals, as using SFM-140 (80 positions) wastes 42 unconnected pins and increases PCB footprint by over 35 mm. Smaller connectors also reduce per-unit cost in volume production. For applications such as 32-bit parallel data buses plus 6 control lines, the 38-position count is a natural fit without over-engineering the interconnect.
