What are the key features of SFM-108-L2-LM-D?
- 16-position dual-row layout on 0.050-inch (1.27 mm) pitch delivers high signal density in a compact 0.555 in x 0.185 in SMD footprint
- Gold contact finish on mating surfaces ensures low and stable contact resistance over thousands of mate/unmate cycles for high-reliability applications
- Low-mating-force (LM) socket design reduces mechanical stress on SMD pads during board assembly and field servicing
- Dual-row (D) configuration and female socket body provide robust board-to-board mating compatible with Samtec TSM and TFM plug series
What is SFM-108-L2-LM-D used for?
The SFM-108-L2-LM-D is well suited for high-density board-to-board interconnects in FPGAs, microprocessor daughtercard assemblies, and high-speed data acquisition modules where a 0.050-inch pitch minimizes routing congestion. Its gold-plated 16-position dual-row socket enables reliable mating cycles in test-fixture spring-probe applications and removable module connectors operating at signal rates up to several gigabits per second. The compact SMD body also makes it a popular choice in RF front-end boards and compact industrial embedded computing platforms.

Frequently Asked Questions
What contact pitch and position count does the SFM-108-L2-LM-D offer for board-to-board interconnects?
The SFM-108-L2-LM-D provides 16 positions arranged in a dual-row layout on a 0.050-inch (1.27 mm) pitch, giving 8 contacts per row. The compact 1.27 mm pitch allows a full 16-signal interface within a body length of only 0.555 inch, making it practical for space-constrained daughtercard designs and stacked PCB assemblies.
Why is gold contact finish important for the SFM-108-L2-LM-D in high-reliability applications?
Gold plating on the mating contacts provides a noble-metal surface that resists oxidation and corrosion, maintaining a consistently low contact resistance over the rated number of mate and unmate cycles. In test fixtures, automated board testers, or frequently serviced modules, gold contact finish outperforms tin-plated alternatives by sustaining signal integrity even after hundreds of insertions in environments with elevated humidity or industrial contaminants.
What does the low-mating-force (LM) designation mean for PCB assembly of the SFM-108-L2-LM-D?
The LM (low-mating-force) design reduces the insertion force required to mate the socket with its plug counterpart. Lower insertion force is critical in surface-mount applications because it minimizes the mechanical bending stress on the PCB and reduces the risk of cracked solder joints at the SMD pads. This is especially important in automated board-level test fixtures where the same socket may be cycled hundreds of times.
Which Samtec plug series is compatible with the SFM-108-L2-LM-D dual-row socket strip?
The SFM series female socket strips are mechanically and electrically compatible with Samtec's TSM (through-hole) and TFM (surface-mount) dual-row plug series, both sharing the 0.050-inch pitch standard. Designers can pair the SFM-108-L2-LM-D with an 8-position-per-row TFM plug to create a 16-pin board-to-board stack with mated heights configurable from approximately 4 mm to over 20 mm depending on post length.
