Key Features
- 42-position dual-row layout at 0.050" (1.27 mm) pitch for high-density interconnects
- Surface-mount termination with tape-and-reel packaging for automated PCB assembly
- Gold-plated contacts ensure low contact resistance and long mating cycle life
Applications
The SFM-121-02-STL-D-A-K-TR is suited for high-density board-to-board mezzanine connections in data communications equipment, embedded computing modules, and test and measurement instruments. Its 0.050" pitch and surface-mount footprint allow designers to minimize PCB real estate in space-constrained applications such as blade servers and industrial control boards.

Frequently Asked Questions
What is the pin count and row configuration of the SFM-121-02-STL-D-A-K-TR?
The SFM-121-02-STL-D-A-K-TR has 42 positions arranged in a dual-row configuration at a 0.050" (1.27 mm) pitch, providing 21 pins per row for high-density interconnects on compact PCB layouts.
Which PCB assembly processes are compatible with this SAMTEC socket strip?
This component uses surface-mount termination and comes in tape-and-reel (TR) packaging, making it fully compatible with automated pick-and-place and reflow soldering processes at standard reflow temperatures up to 260°C.
When should an engineer choose the SFM-121-02-STL-D-A-K-TR over a through-hole alternative for a mezzanine design?
When board thickness is limited and PCB height must be minimized, the SMT version saves up to 3 mm in board height compared to through-hole counterparts, making it preferable for stacked module designs where overall system height is constrained to under 10 mm.
