Applications
SFM-103-L2-S-D-K-TR is used in compact embedded systems, sensor modules, and small PCB assemblies where a low-position-count dual-row 1.27 mm pitch socket is needed for reliable signal interconnect. Its small 6-position footprint suits applications such as microcontroller debug headers, sensor breakout boards, and space-constrained mezzanine card interfaces.

Frequently Asked Questions
What is the contact count and pitch of the SFM-103-L2-S-D-K-TR socket strip?
The SFM-103-L2-S-D-K-TR has 6 total positions in a dual-row arrangement, giving 3 contacts per row, with a 0.050" (1.27 mm) pitch. This compact layout suits small-scale board-to-board interconnects in sensor modules, debug headers, and embedded computing designs where PCB space is severely limited.
What does the staggered (S) tail designation mean for soldering the SFM-103-L2-S-D-K-TR?
The staggered (S) solder tail configuration offsets the contact tails in alternating positions to widen pad separation on the PCB land pattern. This reduces solder bridging risk during reflow and improves mechanical solder joint strength, which is particularly useful for fine 1.27 mm pitch dual-row SMT sockets assembled in automated reflow processes.
How does the SFM-103-L2-S-D-K-TR compare to higher-position-count SFM series connectors?
The SFM-103-L2-S-D-K-TR has only 6 positions compared to variants like SFM-129 (58 positions) or SFM-130 (60 positions), making it the choice when minimal signal count is needed. All share the same 0.050" (1.27 mm) pitch and dual-row high-reliability series design, so the same mating header family applies regardless of position count.
What operating temperature range can the SFM-103-L2-S-D-K-TR withstand in industrial environments?
As part of SAMTEC's high-reliability SFM series, the SFM-103-L2-S-D-K-TR is rated for an operating temperature range of -55°C to +125°C. This broad thermal range qualifies the 6-position 1.27 mm pitch socket for harsh industrial, automotive, and defense applications where connectors face wide ambient temperature swings.
