Key Features
- 54-position dual-row socket with 0.050-inch (1.27 mm) pitch for high-density board-to-board interconnection
- High-reliability gold-plated contacts ensuring low-resistance mating in vibration-prone environments
- Tape-and-reel (TR) packaging compatible with automated SMT pick-and-place assembly lines
Applications
The SFM-127-L2-F-D-A-K-TR is designed for high-density board-to-board and mezzanine stacking applications in telecom, industrial, and test equipment where space is at a premium. Its 0.050-inch pitch and 54 dual-row positions allow a large number of signal and power connections within a compact 27-position-per-row footprint. The surface-mount format and tape-and-reel packaging make it well-suited for high-volume automated PCB assembly in embedded computing and networking hardware.

Frequently Asked Questions
How many positions and rows does the SFM-127-L2-F-D-A-K-TR socket strip have?
The SFM-127-L2-F-D-A-K-TR has 54 total positions arranged in a dual-row configuration with 27 pins per row and a 0.050-inch (1.27 mm) pitch between positions. This high-density layout allows 54 signal or power connections within a compact surface-mount footprint, making it suitable for mezzanine and board-to-board stacking applications.
For high-speed signal integrity, how does the SFM-127-L2-F-D-A-K-TR perform in demanding industrial environments?
The SFM-127-L2-F-D-A-K-TR uses high-reliability gold-plated contacts rated for multiple mating cycles, maintaining low contact resistance below 20 mΩ typical in vibration-prone industrial environments. The 1.27 mm pitch reduces crosstalk between adjacent signal lines at frequencies up to several hundred MHz, and SAMTEC's controlled-impedance design supports high-speed digital interfaces in test and measurement equipment.
What packaging format does SFM-127-L2-F-D-A-K-TR use and how does it support automated PCB assembly?
The SFM-127-L2-F-D-A-K-TR uses tape-and-reel (TR) packaging, which feeds the 54-position SMT socket strips directly into automated pick-and-place machines on standard 8 mm or wider carrier tape. This eliminates manual placement errors on high-volume SMT assembly lines and supports reflow soldering at standard lead-free profiles up to 260°C peak, compatible with IPC/JEDEC J-STD-020 MSL requirements.
