What are the key features of SFM-121-T2-STL-D-A-K-TR?
- 42-position dual-row configuration at 0.050-inch (1.27 mm) pitch for high-density board-to-board signal routing
- Tape-and-reel (TR) packaging enabling automated pick-and-place SMT assembly for high-volume production
- High-reliability SAMTEC SFM series construction for demanding industrial, telecom, and defense interconnect requirements
What is SFM-121-T2-STL-D-A-K-TR used for?
The SFM-121-T2-STL-D-A-K-TR is used in compact mezzanine board stacking applications where 42 signal connections must be made in a minimal footprint at 0.050-inch pitch. It suits industrial control modules, telecom line cards, and embedded compute boards that require reliable, repeatable surface-mount socket connectivity. The tape-and-reel packaging streamlines high-volume SMT production lines, reducing handling time and improving placement accuracy.

Frequently Asked Questions
How many contact positions does SFM-121-T2-STL-D-A-K-TR provide, and on what pitch?
The SFM-121-T2-STL-D-A-K-TR provides 42 positions in a dual-row layout on a 0.050-inch (1.27 mm) pitch. This results in 21 contacts per row, giving designers a compact 42-pin socket that occupies approximately 1.05 inches of board length.
What does the TR suffix indicate, and how does it affect manufacturing workflow?
The TR suffix denotes tape-and-reel packaging, meaning connectors are individually loaded onto carrier tape for automated pick-and-place SMT assembly. This format supports reel quantities typically of 500 or more units, improving throughput and reducing manual handling on high-volume production lines.
For a compact industrial control PCB, why choose the dual-row SFM-121-T2-STL-D-A-K-TR over a single-row 42-position alternative?
A dual-row configuration at 0.050-inch pitch packs 42 contacts into roughly half the board-edge length of a single-row equivalent, freeing PCB real estate for additional circuitry. This is critical in industrial control modules and embedded compute cards where width constraints limit connector length to under 30 mm.
