What are the key features of SFM-123-T2-STL-D-K-TR?
- 46-position dual-row surface-mount socket strip at 0.050" (1.27mm) pitch enabling ultra-high-density SMT board-to-board mating
- High-reliability stainless-steel (STL) contact material for superior spring force retention and extended mating cycle life
- Tape-and-reel (TR) packaging supports automated SMT pick-and-place assembly for high-volume production lines
- Dual-row configuration maximizes signal density per unit board length compared to single-row alternatives
What is SFM-123-T2-STL-D-K-TR used for?
The SFM-123-T2-STL-D-K-TR is engineered for high-density board-to-board and mezzanine interconnects in compact embedded systems, FPGAs, and processor module designs where 0.050" pitch reduces PCB footprint versus 0.100" alternatives. Its stainless-steel contacts and high-reliability rating suit aerospace, defense, and industrial applications demanding long mating cycle life and robust vibration performance. The tape-and-reel format makes it directly compatible with automated SMT assembly lines in high-volume consumer electronics, networking, and data storage hardware.

Frequently Asked Questions
How does the 0.050" pitch of SFM-123-T2-STL-D-K-TR compare to standard 0.100" connectors for dense PCB layouts?
At 0.050" (1.27mm) pitch, SFM-123-T2-STL-D-K-TR occupies roughly half the board length of equivalent 0.100" (2.54mm) pitch connectors for the same 46-position count, enabling significantly denser PCB layouts in compact embedded, networking, and portable instrumentation designs.
What material advantage does the stainless-steel (STL) contact variant offer in harsh environments?
Stainless-steel contacts in SFM-123-T2-STL-D-K-TR maintain higher spring force over a wider temperature range than standard phosphor bronze, sustaining reliable contact resistance below 30 mΩ across extended mating cycles and mechanical stress conditions encountered in aerospace and defense assemblies.
Is SFM-123-T2-STL-D-K-TR suitable for high-volume automated SMT assembly, and what packaging does it ship in?
Yes, the -TR suffix confirms tape-and-reel packaging compatible with standard SMT pick-and-place equipment. This enables automated placement at typical line speeds, supporting high-volume production runs in consumer electronics, telecommunications, and embedded computing manufacturing with minimal manual handling.
For a mezzanine FPGA daughtercard design, how many signal lines can SFM-123-T2-STL-D-K-TR route in dual-row configuration?
The dual-row 46-position configuration provides 46 individual signal or power contacts across 2 rows of 23 pins each, all at 0.050" (1.27mm) pitch. This makes SFM-123-T2-STL-D-K-TR suitable for mezzanine FPGA cards needing dense I/O, differential pairs, or mixed power-and-signal routing in a compact SMT footprint.
