What are the key features of TFC-143-02-F-D-A?
- 86-position dual-row layout on 0.050 inch (1.27 mm) pitch provides 172 total contact positions in a narrow PCB footprint
- Tiger Eye bifurcated beam contacts create 2 independent touch points per pin, minimizing contact resistance over hundreds of mating cycles
- Cost-effective terminal strip construction lowers per-contact cost in high-channel-count designs without sacrificing signal integrity
What is TFC-143-02-F-D-A used for?
The TFC-143-02-F-D-A is designed for high-channel-count mezzanine and backplane socket applications in FPGA development platforms, high-density data acquisition systems, and advanced instrumentation where 0.050 inch pitch terminal strips maximize signal routing density. With 172 contact positions available across the dual-row 86-position layout, a single connector replaces multiple lower-density parts, simplifying BOM management. The Tiger Eye contacts mate reliably with standard 0.025 inch square-post headers used throughout the SAMTEC TFM and SFM connector families.

Frequently Asked Questions
How should the 86-position count guide TFC-143-02-F-D-A layout planning?
The 86-position count supports high-density board-to-board routing, so engineers should confirm signal grouping, mating clearance, and connector retention before release.
Why does the 0.050 inch pitch matter for this Tiger Eye terminal strip?
The 0.050 inch pitch, equivalent to 1.27 mm, enables compact interconnect spacing while requiring accurate footprint selection and assembly inspection.
Which mating detail is important for the 0.025 inch square-pin header interface?
The 0.025 inch square-pin compatibility should be checked against the selected mating header, insertion depth, plating, and stack height before procurement.
