What are the key features of TFC-144-02-FM-D-A-K?
- 88-position dual-row layout at 0.050-inch (1.27 mm) pitch delivers very high signal density — 44 contacts per row — in a compact board footprint
- Tiger Eye low-insertion-force contact design reduces assembly mating force across all 88 positions, protecting fragile PCB pads during connector seating
- Cost-effective terminal strip construction enables high-volume BOM cost reduction without compromising signal integrity on all 88 channels
What is TFC-144-02-FM-D-A-K used for?
The TFC-144-02-FM-D-A-K is used in high-density board-to-board interconnect applications such as FPGA development boards, server backplanes, and multi-channel data acquisition systems that require routing 88 signals across a single compact dual-row connector. Its 0.050-inch pitch and Tiger Eye contacts make it an efficient choice for instrumentation modules, embedded computing, and telecommunications line cards where signal density per millimeter of connector length is a critical design constraint.

Frequently Asked Questions
How many contact positions does TFC-144-02-FM-D-A-K offer per row, and what is its total position count?
The TFC-144-02-FM-D-A-K is an 88-position connector with 44 contacts per row arranged in a dual-row format at a 0.050-inch (1.27 mm) pitch. This high density allows routing 88 independent signal lines through a footprint only about 44 positions long, saving significant PCB area compared to single-row alternatives.
Why is the Tiger Eye contact design in TFC-144-02-FM-D-A-K advantageous for multi-board assemblies?
The Tiger Eye contact mechanism requires lower insertion force than conventional stamped contacts, which is critical when simultaneously engaging all 88 positions of this connector. Reduced mating force minimizes the risk of board flexure, solder joint cracking, or pad lifting during connector seating in multi-board assemblies and backplane systems.
Which high-channel-count system designs are best served by TFC-144-02-FM-D-A-K?
This 88-position connector suits FPGA daughter cards, data acquisition modules, and telecommunications line cards that must route 88 or more signal channels across a board edge at a 1.27 mm pitch. Server backplane designs and industrial control racks with multiple hot-swappable modules also benefit from its cost-effective construction and reliable dual-row contact layout.
How does TFC-144-02-FM-D-A-K's 88-position count compare to TFC-122-02's 44 positions for backplane design?
The TFC-144-02-FM-D-A-K provides exactly twice the contact count of the TFC-122-02 series, consolidating 88 signals into a single connector rather than requiring 2 separate 44-position strips. This reduces the number of connector placements per board, lowers assembly complexity, and shortens the PCB routing distance between paired differential signal lines in high-speed backplane designs.
