What are the key features of SFM-149-02-F-D-LC?
- 98-position dual-row SMT socket strip on 1.27 mm (0.050") pitch for ultra-high density mezzanine and daughter card interconnects
- High-reliability (HR) rated gold-plated female contacts supporting extended mating cycle life in demanding aerospace and industrial applications
- Low-clearance (LC) profile minimizes board stack height for compact module stacking designs with tight vertical clearance budgets
What is SFM-149-02-F-D-LC used for?
The SFM-149-02-F-D-LC is designed for ultra-high density mezzanine board and daughter card interconnects in aerospace, defense, and high-reliability industrial systems requiring up to 196 total signal contacts at 1.27 mm pitch. Its low-clearance SMT profile supports compact card-stack assemblies where board-to-board spacing must be minimized to fit within enclosure constraints. The high-reliability gold-plated contacts ensure long-term signal integrity in environments subject to vibration, thermal cycling from -55°C to +125°C, and frequent daughter card removal and insertion.

Frequently Asked Questions
How many total contact positions does SFM-149-02-F-D-LC provide in its dual-row layout?
SFM-149-02-F-D-LC has 49 positions per row in a dual-row configuration, delivering 98 total female socket contacts at 1.27 mm (0.050") pitch. This high density makes it suitable for FPGA expansion, DSP mezzanine, or backplane card interfaces requiring 80 or more signal lines in a compact SMT footprint.
What does the LC (low-clearance) designation mean for board stack height in SFM-149-02-F-D-LC?
The LC (low-clearance) designation on SFM-149-02-F-D-LC means the connector is designed with a reduced above-board profile, typically enabling board-to-board stack heights below 4 mm when mated with the corresponding header. This is critical in stacked module designs used in embedded computing, ruggedized military hardware, and compact data acquisition systems where every millimeter of height matters.
For which high-reliability application environments is SFM-149-02-F-D-LC specifically suited?
SFM-149-02-F-D-LC's high-reliability (HR) construction and -55°C to +125°C temperature rating make it well suited for aerospace avionics, military rugged computing, satellite payload boards, and industrial test equipment that demand long mating cycle life, resistance to thermal shock, and consistent contact resistance below 20 mΩ across the operating temperature range.
How does the 1.27 mm pitch of SFM-149-02-F-D-LC compare to a standard 2.54 mm pitch socket strip for the same 98-position count?
At 1.27 mm pitch, SFM-149-02-F-D-LC occupies roughly half the PCB length of an equivalent 2.54 mm pitch connector for the same 98-position dual-row count. For a 49-position row, this translates to approximately 62 mm at 1.27 mm pitch versus 124 mm at 2.54 mm pitch, enabling more compact board layouts without reducing signal count.
