Key Features
- 0.050" (1.27 mm) pitch dual-row layout delivers 86 positions in a compact SMT footprint for high-density FPC and board-to-board connections
- Tiger Eye contact design provides consistent wiping action and low contact resistance across the rated 2 A per pin current capacity
- Tape-and-reel (-TR) packaging enables fully automated pick-and-place assembly at high production volumes
- Dual-row configuration doubles signal density versus single-row strips, reducing total connector length and board real estate
Applications
TFC-143-02-L-D-A-K-TR is used in high-density FPC-to-PCB and board-to-board interconnect applications in server backplanes, storage controllers, and telecom line cards where 86 signals must cross in a 0.050" pitch footprint. Its 2 A per-contact rating allows mixing power and signal pins within the same connector, simplifying layout in compact embedded computing modules. Tape-and-reel packaging makes it compatible with high-volume SMT reflow assembly lines.

Frequently Asked Questions
How many signal positions does TFC-143-02-L-D-A-K-TR provide, and what is the per-pin current rating?
TFC-143-02-L-D-A-K-TR provides 86 positions arranged in 2 rows at 0.050" (1.27 mm) pitch, yielding 43 columns across the connector length. Each contact is rated for up to 2 A continuous current, making it suitable for mixed signal and power distribution within the same 86-pin connector in server blade or storage controller applications.
What does the Tiger Eye contact design in TFC-143-02-L-D-A-K-TR offer compared to standard beam contacts?
SAMTEC's Tiger Eye contact geometry uses a dual-beam wiping action that maintains a normal force of approximately 100 gF per contact even after repeated insertions. This ensures stable contact resistance below 20 milliohms across the rated mating cycles, which is significantly better than single-beam alternatives that can exhibit intermittent opens after 50 or more mate/unmate cycles in field-serviceable equipment.
For high-volume PCB assembly, why is the -TR (tape-and-reel) option of TFC-143-02-L-D-A-K-TR important?
The -TR suffix means TFC-143-02-L-D-A-K-TR is packaged on a standard 13-inch reel in tape pockets compatible with industry-standard SMT pick-and-place feeders. This eliminates manual loading of individual connectors, allowing placement rates above 3,000 components per hour on modern assembly equipment. At volumes above 500 boards per day, tape-and-reel reduces assembly labor cost and mis-orientation defects compared with tray-packed alternatives.
Can TFC-143-02-L-D-A-K-TR mate with SAMTEC's TFM or FLE series receptacles for board-stacking applications?
TFC-143-02-L-D-A-K-TR is designed to mate with SAMTEC TFM or FLE series receptacles in the 0.050" Tiger Eye family. The dual-row 0.050" pitch is compatible with standard 2×43 receptacle housings, supporting board-to-board stacking heights from approximately 4 mm up to 12 mm depending on the receptacle post length chosen. This family is widely used in FPGA mezzanine card (FMC) and high-speed backplane applications.
