Key Features
- 92-position dual-row configuration on 0.050 inch (1.27 mm) pitch for high-density PCB interconnects
- Surface-mount termination style enables reflow soldering and automated PCB assembly
- High-reliability socket strip construction rated for repeated mating cycles in demanding environments
- Compatible with SAMTEC TSM and TSW male header series for matched board-to-board stacking
Applications
The SFM-146-L2-SM-D-A is used in board-to-board stacking and module daughter-card assemblies where high pin counts and fine 0.050 inch pitch save board space. Its 92-position dual-row layout suits FPGA mezzanine cards, industrial computing modules, and test and measurement equipment requiring dense signal interconnects. The surface-mount footprint integrates directly with automated reflow soldering lines for high-volume production.

Frequently Asked Questions
How many positions does the SFM-146-L2-SM-D-A provide and how are they arranged?
The SFM-146-L2-SM-D-A provides 92 positions arranged in a dual-row configuration on a 0.050 inch (1.27 mm) pitch. This gives 46 pins per row and allows very high signal density on compact PCBs used in FPGA mezzanine and module interconnect designs.
What mating SAMTEC headers are compatible with the SFM-146-L2-SM-D-A socket strip?
The SFM-146-L2-SM-D-A is designed to mate with SAMTEC TSM and TSW series male headers sharing the same 0.050 inch pitch and dual-row layout. Selecting a header with matched stack height achieves a secure, low-profile board-to-board interconnect with reliable electrical contact across all 92 positions.
Is the SFM-146-L2-SM-D-A suitable for automated reflow soldering assembly?
Yes. The surface-mount termination style of the SFM-146-L2-SM-D-A is compatible with standard reflow soldering processes, allowing pick-and-place machine placement and wave or reflow oven soldering. This reduces assembly cost compared to through-hole alternatives and supports high-volume production runs requiring consistent joint quality across all 92 contacts.
What applications commonly use the SFM-146-L2-SM-D-A in high-density interconnect designs?
Typical applications include FPGA mezzanine daughter cards, industrial single-board computers, software-defined radio modules, and test equipment backplanes where 92 signal or power connections must be routed through a 0.050 inch pitch interface. The dual-row format reduces the connector footprint length by half compared to a single-row 92-pin strip at the same pitch.
