Frequently Asked Questions
What is the pitch and pin count of the SFM-140-T2-H-D-A, and how does that affect PCB layout density?
The SFM-140-T2-H-D-A features an 80-position dual-row layout on a 0.050-inch (1.27 mm) pitch, enabling very high density interconnection. This tight spacing allows designers to route 80 signals within a compact PCB footprint, reducing board area significantly compared to standard 2.54 mm pitch connectors.
Which types of mating connectors are compatible with the SFM-140-T2-H-D-A in a board-to-board stack?
The SFM-140-T2-H-D-A is designed to mate with SAMTEC's SFM and SFM-series header strips sharing the 0.050-inch (1.27 mm) pitch standard. Paired headers provide 80 pins of dual-row connectivity, supporting stack heights suitable for compact multi-board assemblies in industrial and telecommunications equipment.
How does the surface mount package of SFM-140-T2-H-D-A affect manufacturing and reliability?
As a surface mount (SMT) component, the SFM-140-T2-H-D-A is compatible with standard reflow soldering processes, eliminating the need for through-hole drilling and enabling automated PCB assembly. SMT placement at 1.27 mm pitch ensures mechanical stability and consistent solder joints across all 80 positions, reducing field failure rates.
In what industrial or embedded systems applications is the SFM-140-T2-H-D-A most commonly used?
This 80-position, 1.27 mm pitch socket strip is commonly deployed in FPGA mezzanine cards, data acquisition modules, industrial control backplanes, and telecom line cards. Its high-reliability contact system and fine 0.050-inch pitch make it a preferred choice wherever 80 signals must be routed between boards in a space-constrained design.
