Key Features
- 94 positions in a dual-row 1.27 mm (0.050 inch) pitch footprint delivering maximum I/O density for mezzanine and FPGA daughter card socket applications
- Low-clearance (LC) surface-mount design minimises board-to-board stacking height to under 3 mm for slim embedded module enclosures
- High-reliability contact construction maintains signal integrity across hundreds of mating cycles at signal levels as low as a few milliamps
- Dual-row (D) layout with 47 contacts per row allows broad bus interfaces such as memory or high-speed differential pairs to be routed in a compact footprint
Applications
SFM-147-02-SM-D-LC is designed for high-density mezzanine interconnects in telecommunications line cards, FPGA carrier boards, and industrial computing modules where 94 contacts must fit within a compact 1.27 mm pitch surface-mount footprint. Its low-clearance design is critical in blade server enclosures and aerospace avionics modules that impose strict height limits between stacked boards. The connector is also used in high-reliability military and medical electronics that demand consistent contact performance across wide temperature ranges.

Frequently Asked Questions
How many signal contacts does SFM-147-02-SM-D-LC provide and how are they arranged?
SFM-147-02-SM-D-LC offers 94 total contacts arranged in 2 rows of 47 at a 1.27 mm (0.050 inch) pitch, enabling a 94-pin bus interface in a surface-mount footprint roughly half the size of a comparable 2.54 mm pitch connector.
What does the low-clearance (LC) suffix mean for the stacking height of SFM-147-02-SM-D-LC?
The LC designation specifies a reduced above-board profile, typically under 3 mm, that allows mated board pairs to achieve stacking heights of 5 mm or less — essential for slim blade servers, rack-mount cards, and aerospace avionics assemblies where vertical space between PCBs is tightly controlled.
Which high-reliability application segments commonly use SFM-147-02-SM-D-LC socket strips?
SFM-147-02-SM-D-LC is specified in aerospace avionics, military electronics, and medical imaging modules where high-reliability contacts must sustain low-resistance continuity across hundreds of mating cycles and temperatures from -55 °C to +125 °C without degradation.
How does SFM-147-02-SM-D-LC interface with its mating header in a board-to-board assembly?
SFM-147-02-SM-D-LC mates with SAMTEC-compatible 1.27 mm pitch dual-row header strips; the female socket contacts accept 0.64 mm square header pins and the surface-mount pads are reflowed in a standard SAC305 process at up to 260 °C to secure the 94-pin interface to the PCB.
