Key Features
- 86-position dual-row layout at 0.050" (1.27 mm) pitch enables very high circuit density in compact PCB assemblies
- Tiger Eye dual-beam contacts deliver low contact resistance under 20 mΩ and reliable mating over hundreds of cycles
- Cost-optimized terminal strip design lowers per-circuit connector cost in high-volume production runs
Applications
The TFC-143-02-F-D-A-K serves high-channel-count signal routing in industrial automation, data acquisition systems, and embedded computing cards where 86 circuits must be interconnected within a minimal board area. Its 1.27 mm pitch dual-row configuration is particularly suited for compact backplane interfaces and mezzanine card connectors. The cost-effective Tiger Eye design supports volume production in telecommunications and instrumentation applications.

Frequently Asked Questions
How many circuits does the TFC-143-02-F-D-A-K support and what is its contact pitch?
The TFC-143-02-F-D-A-K provides 86 positions in a dual-row arrangement with a 0.050 inch (1.27 mm) pitch, giving 43 contacts per row. This high-density layout allows designers to route 86 independent signal circuits across a connector body shorter than 60 mm, making it one of the most space-efficient terminal strip options in the SAMTEC TFC series.
For a data-acquisition backplane needing over 80 signal lines, how does the TFC-143-02-F-D-A-K compare to a lower-density alternative?
Compared to a 0.100 inch pitch strip that would need a 110 mm body for 86 contacts, the TFC-143-02-F-D-A-K achieves the same 86-circuit count in approximately half the board length at 1.27 mm pitch. Gold-plated Tiger Eye contacts maintain contact resistance under 20 mΩ over 200 mating cycles, and the rated operating range of -55°C to +125°C matches typical industrial data-acquisition requirements without needing a premium connector grade.
What current and voltage ratings should engineers verify before using TFC-143-02-F-D-A-K in a power-plus-signal application?
SAMTEC TFC series terminal strips at 1.27 mm pitch are rated for approximately 1 A per contact at low signal voltages up to 125 V AC/DC. For mixed power-and-signal layouts using all 86 positions, engineers should derate current per contact when adjacent pins also carry current, keeping total bus loading within thermal limits. Consult the SAMTEC TFC datasheet for the exact current-derating curve versus ambient temperature from -55°C to +125°C.
