What are the key features of SFM-142-L2-F-D-A?
- 84-position dual-row SMT socket strip at 0.050" (1.27 mm) pitch for ultra-high-density board-to-board connections
- Phosphor bronze contacts with gold plating maintain contact resistance below 20 mΩ across extended mating life
- Surface-mount termination enables automated reflow assembly, reducing placement time on high-volume PCB production lines
What is SFM-142-L2-F-D-A used for?
The SFM-142-L2-F-D-A is ideal for mezzanine module stacking in FPGA development boards, embedded computing platforms, and high-speed signal-routing backplanes where 84 I/O lines must be densely interconnected. Its 0.050" pitch and SMT footprint suit compact industrial controllers and telecom line cards that require reliable multi-cycle mating in vibration-prone environments. Defense electronics and ruggedized test equipment also rely on this connector's high reliability rating for field-deployable systems.

Frequently Asked Questions
How many positions does the SFM-142-L2-F-D-A offer, and how are they arranged?
The SFM-142-L2-F-D-A provides 84 total positions in a dual-row layout with a 0.050" (1.27 mm) pitch. This arrangement gives 42 contacts per row, enabling dense signal routing between stacked PCBs in a compact footprint suitable for FPGA mezzanine and embedded computing designs.
What pitch does the SFM-142-L2-F-D-A use, and how does that compare with standard 0.100" connectors?
The SFM-142-L2-F-D-A uses a 0.050" (1.27 mm) pitch, which is exactly half the spacing of standard 0.100" connectors. This halved pitch lets designers route 84 signals in roughly the same PCB length that a 0.100" strip would need for 42 signals, doubling interconnect density without increasing board area.
Can the SFM-142-L2-F-D-A handle differential signal pairs for high-speed interfaces like LVDS or SerDes?
Yes, the 0.050" pitch dual-row layout of the SFM-142-L2-F-D-A allows differential pairs to be routed adjacently across the 84 positions, supporting protocols such as LVDS at speeds up to several hundred MHz. For optimal signal integrity, adjacent row contacts should carry the P and N signals of each pair, keeping intra-pair spacing to 1.27 mm.
Is the SFM-142-L2-F-D-A compatible with automated pick-and-place assembly equipment?
Yes, SAMTEC SFM series SMT connectors including the SFM-142-L2-F-D-A are designed for automated pick-and-place assembly. The component is supplied on tape-and-reel packaging and features a flat top surface compatible with vacuum nozzles, supporting standard reflow soldering at peak temperatures up to 260 °C per J-STD-020.
