Key Features
- 98-position dual-row socket strip with 0.050" (1.27 mm) pitch for high-density PCB interconnects
- Gold-plated phosphor bronze contacts ensure reliable electrical performance across thousands of mating cycles
- Surface-mount compatible design with tight mechanical tolerances for automated assembly on compact boards
Applications
The SFM-149-T2-F-D-A-K is widely used in high-density mezzanine board stacking, FPGAs, and backplane interconnect systems where 98 signal lines must be routed in a compact 0.050" pitch footprint. It suits test and measurement equipment, embedded computing modules, and ruggedized industrial controllers that demand reliable mating over extended thermal cycles. Its surface-mount form factor also makes it ideal for automated PCB assembly in volume production runs.

Frequently Asked Questions
How many signal positions does the SFM-149-T2-F-D-A-K provide, and what row configuration is used?
The SFM-149-T2-F-D-A-K provides 98 positions arranged in a dual-row configuration with a 0.050" (1.27 mm) pitch, allowing a high pin density suited to compact mezzanine and board-stacking applications.
Which PCB assembly process is compatible with the SFM-149-T2-F-D-A-K, and what mounting style does it use?
This connector uses surface-mount technology (SMT), making it compatible with standard reflow soldering processes. The 0.050" pitch SMT footprint enables placement by automated pick-and-place machines, supporting high-volume production with consistent joint quality.
What contact material and finish does the SFM-149-T2-F-D-A-K use, and how does that affect mating cycle life?
SAMTEC SFM series connectors use phosphor bronze contacts with gold plating over a nickel barrier. Gold plating maintains low contact resistance below 20 mΩ even after repeated mating cycles, making the connector suitable for systems requiring hundreds of mate/unmate operations.
Can the SFM-149-T2-F-D-A-K be used in a board-to-board stacking application, and what mating connector is recommended?
Yes, the SFM-149-T2-F-D-A-K is designed for board-to-board stacking. It mates with SAMTEC's SSM or SFM series male strip connectors at 0.050" pitch. Stack height is determined by the selected mating connector, commonly available in 4 mm to 20 mm options.
