Key Features
- 90-position dual-row surface-mount design at 0.050 inch pitch maximizes signal density in compact mezzanine and stacking applications
- High-reliability socket construction with gold-plated contacts ensures consistent low-resistance mating over the full rated cycle life
- Keyed (K-suffix) housing prevents incorrect insertion orientation, reducing assembly errors on high-pin-count 90-position interfaces
- Surface-mount termination style simplifies automated PCB assembly and eliminates through-hole drilling for high-volume production
Applications
SFM-145-02-F-D-A-K serves as the socket half in high-density board-to-board stacking assemblies for industrial controllers, communications equipment, and medical instrument platforms requiring 90-signal interconnect at 0.050 inch pitch. Its surface-mount footprint and keyed housing make it a reliable choice for automated SMT assembly lines where consistent placement and polarity protection are critical. The high-reliability rating also suits test and measurement modules, FPGA daughterboards, and aerospace-grade backplane designs with extended lifecycle requirements.

Frequently Asked Questions
How does the keyed housing on SFM-145-02-F-D-A-K protect a 90-position interface during PCB assembly?
The K-suffix keyed housing on SFM-145-02-F-D-A-K enforces a single correct mating orientation across the 90-position, dual-row 0.050 inch pitch interface, preventing 180-degree mis-insertion that could damage all 90 signal lines; this protection is especially valuable during automated pick-and-place or manual assembly of stacked mezzanine boards.
What PCB attachment method does SFM-145-02-F-D-A-K use and what are its production advantages?
SFM-145-02-F-D-A-K uses surface-mount termination, allowing it to be placed by standard SMT pick-and-place equipment and reflowed with the rest of the PCB assembly in a single pass, eliminating through-hole drilling costs and enabling both sides of the board to be populated in high-volume manufacturing runs.
In which high-density stacking scenarios does SFM-145-02-F-D-A-K outperform a 0.100 inch pitch socket strip?
At 0.050 inch (1.27 mm) pitch with 90 positions in a dual-row surface-mount format, SFM-145-02-F-D-A-K carries twice the signal count of an equivalent-length 0.100 inch socket, making it the preferred option for FPGA mezzanine boards, high-speed data acquisition modules, and communications line cards where routing 90 differential or single-ended signals into a narrow connector zone is a layout constraint.
What mating connector family is recommended for use with SFM-145-02-F-D-A-K?
SFM-145-02-F-D-A-K mates with SAMTEC's SFM-series or compatible TFM-series male header strips at 0.050 inch pitch and 90 dual-row positions; both series share the same 1.27 mm pitch footprint and are rated for operating temperatures from -55°C to +125°C, ensuring reliable electrical and mechanical performance across the full industrial temperature range.
