Key Features
- 92 positions in dual-row layout on 0.050" (1.27 mm) pitch for maximum signal density in compact PCB footprints
- Right-angle (L) surface-mount termination enabling low-profile horizontal board-to-board or panel-mount interconnects
- High-reliability socket strip construction rated for demanding aerospace, defense, and industrial mating-cycle environments
Applications
The SFM-146-02-L-D-A is used in right-angle board-to-board interconnect applications where a low-profile horizontal mating orientation is required, such as stacked FPGA mezzanine cards, avionics I/O expansion modules, and test fixture interface boards. Its 92-position dual-row layout accommodates 46 differential pairs or mixed bus and power signals within a single connector. The surface-mount footprint integrates seamlessly with automated SMT reflow assembly processes, reducing total manufacturing cost.

Frequently Asked Questions
How many signal positions and rows does the SFM-146-02-L-D-A provide, and at what pitch?
The SFM-146-02-L-D-A provides 92 total positions arranged in 2 rows of 46 contacts each on a 0.050" (1.27 mm) pitch, spanning approximately 59 mm in connector length and allowing 46 differential pairs to route across the board boundary in a single compact SMT socket.
When should an engineer choose the right-angle SFM-146-02-L-D-A instead of a vertical SMT variant?
The right-angle (L) termination of the SFM-146-02-L-D-A is chosen when height above the PCB must stay below 5 mm, such as in front-panel I/O daughter cards, slim embedded computing chassis, or avionics modules where vertical connectors would violate 1U rack height constraints.
Is the SFM-146-02-L-D-A compatible with standard SMT reflow assembly, and what solder temperature profile applies?
Yes, the SFM-146-02-L-D-A uses surface-mount pads compatible with standard SAC305 lead-free reflow profiles peaking at 260°C, allowing it to be placed and soldered in a single reflow pass alongside other SMT components without requiring separate through-hole hand-soldering operations.
