What are the key features of TFC-143-02-FM-D-A-K-TR?
- 86-position dual-row Tiger Eye terminal strip at 1.27mm (0.050") pitch enabling high-density board-to-board interconnect in a compact footprint
- Floating mount (FM) design providing lateral mating tolerance compensation to protect solder joints under board misalignment and thermal cycling stress
- Tape-and-reel (TR) packaging supporting automated SMT pick-and-place assembly at high volumes with consistent component orientation
What is TFC-143-02-FM-D-A-K-TR used for?
TFC-143-02-FM-D-A-K-TR is suited for high-density board stacking applications in embedded computing modules, FPGA mezzanine cards, and industrial backplane systems where 86 contact positions must be reliably interconnected at 1.27 mm pitch. The floating mount design accommodates up to ±0.5 mm of lateral PCB misalignment, reducing mechanical stress at the 86 solder joints during thermal cycling from -40°C to +85°C. Tape-and-reel packaging enables efficient integration into automated SMT production lines for high-volume electronics manufacturing.

Frequently Asked Questions
How does TFC-143-02-FM-D-A-K-TR differ from the TFC-145 variant in terms of position count?
TFC-143-02-FM-D-A-K-TR provides 86 contact positions at 1.27 mm (0.050 inch) pitch, while TFC-145-02 variants offer 90 positions at the same pitch. The 4-position reduction shortens the connector body length by approximately 5 mm, providing a slight footprint saving for PCB layouts where total connector length is constrained by available board area.
What advantage does the floating mount design of TFC-143-02-FM-D-A-K-TR provide for stacked multi-board assemblies?
The floating mount (FM) allows the connector housing to shift laterally by up to ±0.5 mm relative to its PCB footprint, compensating for PCB manufacturing tolerances when two boards are mated face-to-face. This protects all 86 solder joints from shear forces caused by misalignment, preventing fatigue cracking in environments with vibration above 5 g or repeated thermal cycles between -40°C and +85°C.
How does tape-and-reel packaging of TFC-143-02-FM-D-A-K-TR benefit automated assembly compared to loose tube or tray packing?
The -TR tape-and-reel suffix means TFC-143-02-FM-D-A-K-TR ships on continuous reels holding typically 500 or more pieces in consistent orientation, enabling direct loading into SMT pick-and-place feeders. This eliminates the per-unit handling and orientation steps required with loose-packed or tube-packed connectors, reducing placement cycle time per board and improving positional accuracy to within ±0.1 mm for reliable solder joint formation on 86-position fine-pitch pads.
