Key Features
- 88 positions in a dual-row 0.050" (1.27 mm) pitch layout for very high-density signal connectivity
- Tiger Eye low-insertion-force contact design ensures reliable, repeatable mating with minimal pad stress
- Low-profile terminal strip form factor ideal for space-constrained PCB stacking and module interconnects
Applications
The TFC-144-02-L-D-A-K is designed for high-density board-to-board interconnects in embedded computing, FPGA evaluation boards, and industrial automation controllers that require 88 signal lines in a compact 0.050" pitch footprint. Its dual-row configuration maximizes connection density while minimizing board area, making it a preferred choice for module-to-baseboard designs and high-pin-count mezzanine applications.

Frequently Asked Questions
How many signal positions does the TFC-144-02-L-D-A-K provide, and what is its row configuration?
The TFC-144-02-L-D-A-K provides 88 total positions arranged in 2 rows on a 0.050" (1.27 mm) pitch. This dual-row format enables very high density signal routing, allowing up to 88 independent signals to be passed between boards within a compact PCB footprint.
When would a designer choose the TFC-144-02-L-D-A-K over a lower-position-count variant like TFC-127-02-LM-D-A-K-TR?
A designer would select the TFC-144-02-L-D-A-K when 88 signal lines are needed rather than 54, such as in FPGA mezzanine boards or multi-bus backplane designs. The additional 34 positions (88 versus 54) on the same 0.050" pitch provide more routing capacity without increasing connector pitch or requiring a wider connector footprint.
What types of end products commonly use the TFC-144-02-L-D-A-K connector?
Common applications include FPGA evaluation and development boards, embedded computing modules, high-speed data acquisition systems, and industrial automation controllers. Any application requiring 88 board-to-board signal connections on a 0.050" pitch benefits from this 2-row terminal strip design, particularly where board height and footprint area are constrained.
What does the Tiger Eye contact technology contribute to the reliability of the TFC-144-02-L-D-A-K?
Tiger Eye contacts feature a multi-finger compliant design that provides consistent normal force across all 88 positions, resulting in low contact resistance and reliable signal integrity. The low-insertion-force characteristic reduces mechanical stress on connector pads during mating, supporting repeated mate-and-unmate cycles without degradation typical of standard beam contacts.
