Key Features
- 86 positions dual-row layout at 0.050" (1.27 mm) pitch with keying-assist (A) polarization for guided mating, supporting one of the highest signal counts in the Tiger Eye series
- Tiger Eye 4-point wiping contact technology delivering low and stable contact resistance across multiple mating cycles in high-vibration industrial and telecom environments
- Tape-and-reel (TR) packaging format enabling automated SMT pick-and-place assembly for cost-efficient high-volume production of 86-position dual-row connectors
Applications
The TFC-143-02-F-D-A-K-TR is designed for very high-density board-to-board interfaces in FPGA development boards, server blade interconnects, and telecommunications backplane modules where up to 86 dual-row signals at 0.050" pitch must be reliably routed. Its keying-assist polarization prevents mismate in complex multi-connector assemblies where position count makes manual orientation difficult. The tape-and-reel packaging supports high-volume production in factory automation and data center hardware manufacturing lines.

Frequently Asked Questions
How does the TFC-143-02-F-D-A-K-TR compare to the TFC-141-02-F-D-K-TR in position count and mating guidance?
The TFC-143-02-F-D-A-K-TR provides 86 positions versus 82 for the TFC-141-02-F-D-K-TR, offering 4 additional signal channels. It also includes the keying-assist polarization feature (denoted by the 'A' code), which the TFC-141-02-F-D-K-TR lacks, making the 143 variant more suitable for assemblies where mismate prevention is critical at 0.050" pitch.
For an FPGA mezzanine card needing over 80 board-to-board signals at fine pitch, what advantages does TFC-143-02-F-D-A-K-TR offer?
With 86 positions at 0.050" (1.27 mm) pitch in a dual-row footprint, the TFC-143-02-F-D-A-K-TR delivers very high signal density in a compact area, making it suitable for FPGA mezzanine cards, high-speed data acquisition modules, and server blade expansion interfaces. The Tiger Eye 4-point contacts maintain signal integrity across the 86-position interface even in vibration-prone rack-mounted environments.
Is the TFC-143-02-F-D-A-K-TR available in a format compatible with automated SMT assembly?
Yes, the TR suffix confirms that the TFC-143-02-F-D-A-K-TR is packaged in tape-and-reel format, fully compatible with automated pick-and-place equipment. This is especially important for 86-position dual-row connectors at 0.050" pitch, where manual placement accuracy is difficult to maintain consistently across production volumes in the hundreds or thousands.
