Key Features
- 88-position dual-row layout at 0.050" (1.27 mm) pitch delivers very high signal density for compact board-to-board interconnects
- Tiger Eye contact design provides reliable friction-mate connection without latches, supporting repeated daughtercard insertion and removal cycles
- Tape-and-reel (TR) packaging enables high-speed automated SMD pick-and-place assembly in volume production environments
Applications
TFC-144-02-F-D-K-TR is used in high-density board-to-board and daughtercard applications in telecommunications equipment, network switches, and embedded computing systems where 88 signals must be routed across two boards in a compact 0.050" pitch footprint. Its tape-and-reel packaging suits automated SMT production lines for consumer and industrial electronics. The dual-row format enables efficient use of PCB edge area in backplane and mezzanine connector configurations.

Frequently Asked Questions
How does the 0.050" pitch of TFC-144-02-F-D-K-TR compare to standard 0.100" pitch connectors for signal density?
TFC-144-02-F-D-K-TR uses a 0.050" (1.27 mm) pitch, which is half the spacing of standard 0.100" (2.54 mm) pitch connectors, allowing roughly twice the contact density per unit of PCB edge length. In the 88-position dual-row configuration, this means 88 signals fit within approximately 56 mm of connector length, compared to over 112 mm needed for an equivalent 0.100" pitch connector, which is a critical advantage in space-constrained backplane and mezzanine designs.
What assembly method does TFC-144-02-F-D-K-TR support and how does tape-and-reel packaging help production?
TFC-144-02-F-D-K-TR comes in tape-and-reel (TR) format compatible with standard SMD pick-and-place machines, enabling high-speed automated placement on PCBs during reflow soldering. The 0.050" pitch dual-row SMD footprint benefits from precise machine placement since manual alignment of 88 contacts at 1.27 mm spacing is impractical. Tape-and-reel packaging also reduces handling damage and contamination during high-volume production compared to tray or bulk packaging.
In which system architectures is TFC-144-02-F-D-K-TR's 88-position dual-row configuration most beneficial?
TFC-144-02-F-D-K-TR's 88-position dual-row layout at 0.050" pitch is particularly valuable in FPGA mezzanine modules, memory expansion boards, and network interface cards where dozens of parallel data, address, and control lines must cross a board-to-board interface. Telecom line cards, high-speed data acquisition modules, and PCIe carrier boards benefit from the connector's ability to route 88 signals in a compact footprint without resorting to multiple smaller connectors that increase BOM complexity.
How does SAMTEC Tiger Eye contact technology in TFC-144-02-F-D-K-TR ensure reliable mating over many insertion cycles?
SAMTEC's Tiger Eye contact system uses a dual-beam, friction-mate design that maintains consistent contact force over hundreds of mating cycles without relying on a latching mechanism. Each contact beam applies independent normal force on the mating pin, compensating for minor misalignment and vibration in the 0.050" pitch interface. This contact geometry ensures low and stable contact resistance over the full operating temperature range, which is important for high-speed differential signals in 88-position board-to-board assemblies.
