Key Features
- 86-position dual-row layout at 0.050" (1.27 mm) pitch supports high signal density in compact PCB designs
- Tiger Eye contact technology provides low insertion force and consistent contact resistance across repeated mating cycles
- Cost-effective terminal strip design reduces per-pin interconnect cost without sacrificing signal integrity in dense assemblies
Applications
The TFC-143-02-L-D-A-K is designed for high-density signal interconnects in embedded computing, telecommunications line cards, and FPGA mezzanine modules. Its 86-position dual-row layout at 1.27 mm pitch is well-suited for parallel data buses and control signal distribution across adjacent PCBs. It is frequently used in modular system architectures where board-to-board connectivity requires both density and reliable repeated mating performance.

Frequently Asked Questions
How many signal positions does TFC-143-02-L-D-A-K provide per row, and what pitch does it use?
The TFC-143-02-L-D-A-K provides 86 total positions in a dual-row format, yielding 43 pins per row on a 0.050" (1.27 mm) pitch. This arrangement supports high-density signal routing on compact PCB footprints, making it suitable for FPGA mezzanine cards and parallel bus applications where many signals must traverse a board-to-board interface in minimal board area.
For a telecom line card design, how does the Tiger Eye contact compare to standard stamped contacts?
Tiger Eye contacts in the TFC-143-02-L-D-A-K use a unique geometry that delivers lower insertion force than standard stamped contacts while maintaining consistent contact resistance, typically below 50 milliohms per contact. This reduces wear on both the pin and socket during repeated board insertions, extending connector service life in hot-swap or field-replaceable telecom line card designs beyond standard stamped alternatives.
Can TFC-143-02-L-D-A-K be used in automated SMT assembly, and does it ship on tape-and-reel?
The TFC-143-02-L-D-A-K (without -TR suffix) is not packaged on tape-and-reel; it ships in bulk or tube packaging suitable for manual or semi-automated placement. For fully automated SMT pick-and-place lines requiring tape-and-reel feed, the TFC-143-02-L-D-A-K-TR variant is available. Both versions share the same 86-position dual-row 1.27 mm pitch footprint and Tiger Eye contact design.
