Key Features
- 36-position dual-row layout at 0.050" (1.27 mm) pitch for space-efficient high-density board-to-board signal connections
- High-reliability gold-plated contact design supporting multiple mating cycles with stable low contact resistance
- Surface mount format compatible with standard SMT reflow assembly processes for automated high-volume PCB production
Applications
The SFM-118-02-SM-D-A-K is used in mezzanine board stacking, FPGA daughter card interfaces, and high-density embedded computing modules that require 36 dual-row signal connections in a compact 0.050" pitch surface mount footprint. It is also well suited for test and measurement equipment, telecommunications line cards, and modular industrial controllers where high-reliability gold-plated contacts must withstand repeated mating and unmating cycles over the product lifetime.

Frequently Asked Questions
What is the contact pitch and position count of the SFM-118-02-SM-D-A-K, and how does that affect PCB layout density?
The SFM-118-02-SM-D-A-K has 36 positions in a dual-row configuration at a 0.050" (1.27 mm) pitch. This half-pitch spacing compared to standard 0.100" connectors allows the same 36-position count to be placed in roughly half the board length, which is critical for compact mezzanine assemblies in telecommunications and embedded computing where PCB area and signal routing density are tightly constrained.
For a modular FPGA system with multiple daughter cards, what reliability advantage does the SFM-118-02-SM-D-A-K provide over a standard commercial socket strip?
The SFM-118-02-SM-D-A-K is designated as a high-reliability (HR) socket strip, meaning it is built to tighter mechanical tolerances and uses gold-plated contacts that maintain contact resistance below 20 milliohms across a rated number of mating cycles significantly higher than standard commercial connectors. For FPGA daughter card systems that are frequently swapped during development or field maintenance, this translates to more reliable signal integrity across all 36 dual-row positions over the system's service life.
How does the SFM-118-02-SM-D-A-K compare to the SFM-147-T2-LM-D-A-K, and when should an engineer choose the 36-position variant?
Both the SFM-118-02-SM-D-A-K (36 positions) and the SFM-147-T2-LM-D-A-K (94 positions) share the same 0.050" dual-row high-reliability platform from SAMTEC, but the 36-position version occupies a shorter board length of approximately 45 mm versus the 94-position version's longer footprint. Engineers should choose the SFM-118-02-SM-D-A-K when the interface requires 36 or fewer signals, such as a compact 32-bit parallel bus plus power pins, to minimize connector length and board space usage.
