What are the key features of SFM-144-L2-S-D-A-K?
- 88-position dual-row layout at 0.050" (1.27 mm) pitch enabling extremely high signal density in surface-mount configurations
- Keying and locking (K option) prevents mis-mating and ensures consistent connector orientation in high-reliability assemblies
- Surface-mount termination with L2 stand-off height supports automated SMT reflow assembly and controlled coplanarity on production PCBs
What is SFM-144-L2-S-D-A-K used for?
The SFM-144-L2-S-D-A-K serves as a high-density mezzanine connector in FPGA modules, embedded computing boards, and industrial I/O expansion cards where 88 signals must traverse a board-to-board interface in minimal PCB area. Its keyed design prevents reversed insertion in field-replaceable module assemblies. Engineers select it for mission-critical data acquisition systems and rugged electronics requiring reliable multi-cycle mating.

Frequently Asked Questions
How many positions and what pitch does the SFM-144-L2-S-D-A-K provide?
The SFM-144-L2-S-D-A-K offers 88 positions arranged in a dual-row configuration at 0.050" (1.27 mm) pitch, with 44 contacts per row. This layout delivers very high signal density in a compact surface-mount footprint approximately 58 mm long, suitable for FPGA daughter cards and processor module interconnects requiring large pin counts.
What does the K option (keying) add to the SFM-144-L2-S-D-A-K connector?
The K option on the SFM-144-L2-S-D-A-K adds a mechanical keying feature that prevents incorrect 180-degree insertion of the mating connector. This reduces assembly errors and protects sensitive signal lines in dual-row 88-pin interfaces, especially critical in field-replaceable module designs where technicians may swap boards without detailed guidance.
For which embedded computing architectures is the SFM-144-L2-S-D-A-K a suitable mezzanine socket?
The SFM-144-L2-S-D-A-K is appropriate for mezzanine interfaces in COM Express, FPGA SOM (System-on-Module), and custom carrier board designs requiring 88 differential or single-ended signals. Its 0.050" pitch and surface-mount termination allow routing at 100-ohm differential impedance on standard 4-layer PCBs, supporting data rates relevant to Gigabit Ethernet and LVDS video interfaces.
