Key Features
- 6-position dual-row socket at 0.050" (1.27 mm) pitch providing high-density mating in an extremely compact SMT footprint
- High-reliability SFM series design rated for repeated mating cycles with consistent contact force
- Surface mount termination with tape-and-reel (TR) packaging enabling automated pick-and-place assembly
Applications
The SFM-103-T2-S-D-A-K-TR is used in compact IoT sensor nodes, wearable devices, and small-form-factor embedded modules needing a 6-pin dual-row mating socket at 0.050" pitch. The high-reliability SFM series construction suits applications requiring repeated plug-unplug cycles, such as field-replaceable module interfaces and bench test fixtures. Its SMT footprint integrates seamlessly into automated reflow assembly processes for miniaturized electronics.

Frequently Asked Questions
What pitch and position count does SFM-103-T2-S-D-A-K-TR use, and how does this affect mating connector selection?
The SFM-103-T2-S-D-A-K-TR is a 6-position dual-row socket with 0.050" (1.27 mm) pitch. The 1.27 mm pitch is half that of standard 2.54 mm connectors, so it must mate with a compatible 0.050" pitch pin header such as the SAMTEC TSM or TFM series, with each row spaced at 1.27 mm center-to-center.
How many mating cycles can the SFM-103-T2-S-D-A-K-TR endure while maintaining reliable contact resistance?
SAMTEC SFM series high-reliability socket strips are designed for a minimum of 200 mating cycles while maintaining contact resistance below 20 mΩ. This durability makes SFM-103-T2-S-D-A-K-TR suitable for field-replaceable modules, development and test fixtures, and other applications requiring frequent connection and disconnection with fewer than 6 total positions.
In a wearable PCB design, what is the footprint size of the 6-position SFM-103-T2-S-D-A-K-TR?
With 3 contacts per row at 0.050" (1.27 mm) pitch, the mating land area spans approximately 3.81 mm (3 x 1.27 mm) in length and 1.27 mm between dual-row centerlines, yielding a total contact footprint of roughly 3.8 mm x 2.5 mm. This extremely compact area is ideal for wearable and miniaturized PCBs where board space is less than 1 cm² per connector.
What distinguishes the SFM-103 (6-position) from SFM-123 (46-position) for small modular device designs?
The SFM-103 with 6 positions suits interfaces needing only power and a few data lines such as I2C (2-wire) or SPI (4-wire), keeping the connector footprint under 4 mm in length. The SFM-123 with 46 positions is used for wide parallel buses or high pin-count module interfaces spanning over 29 mm. For small modular devices with fewer than 8 signals, SFM-103 is the correct selection.
