Key Features
- 10-position dual-row terminal strip on 0.050-inch (1.27 mm) pitch for high-density board-to-board interconnect in compact PCB designs
- Gold-plated (3 µin) mating contacts over phosphor bronze for reliable low-contact-resistance connections across thousands of mating cycles
- Peg board mounting option provides mechanical keying and alignment during PCB assembly, reducing insertion force mis-alignment errors
Applications
The TFC-105-02-F-D-A-K is suited for high-density board-to-board and mezzanine connections in embedded computing modules, FPGA daughter cards, and RF front-end boards where a 0.050-inch pitch saves significant PCB real estate compared to standard 0.100-inch connectors. It is also used in test and measurement equipment and portable medical devices that require reliable 10-position dual-row signal routing in mechanically constrained enclosures. The gold-plated contacts ensure low-resistance connectivity even in applications with infrequent disconnects and exposure to mild humidity.

Frequently Asked Questions
What pitch and row configuration does the TFC-105-02-F-D-A-K use, and how does it compare to standard connectors?
The TFC-105-02-F-D-A-K uses a 0.050-inch (1.27 mm) pitch in a dual-row (D) configuration with 10 total positions. Compared to standard 0.100-inch pitch connectors, this halves the pin spacing, allowing designers to fit twice as many signals in the same board footprint length — a key advantage in compact embedded and mezzanine board designs.
What contact plating does the TFC-105-02-F-D-A-K use, and what does it mean for connector reliability?
The mating contacts are finished with gold (3 µin) over a nickel barrier on the termination side and tin-over-nickel on the board termination, following industry best practice for low-contact-resistance mating interfaces. Gold plating prevents oxidation, ensuring stable contact resistance below 20 mΩ across thousands of mating cycles in applications like test fixtures and removable daughter cards.
Does the TFC-105-02-F-D-A-K include a mechanical alignment feature for PCB assembly?
Yes. The TFC-105-02-F-D-A-K includes a peg (PEG) board mounting option that provides a physical locating pin aligning to a corresponding hole in the PCB. This prevents rotational misalignment during solder reflow or hand soldering, which is especially important for 0.050-inch pitch connectors where a 1-pin offset would cause a complete wiring error across all 10 positions.
In what types of compact electronic assemblies is the TFC-105-02-F-D-A-K a preferred interconnect solution?
The TFC-105-02-F-D-A-K is preferred in miniaturized stacking board assemblies such as single-board computer I/O expansion modules, FPGA mezzanine cards, and portable medical diagnostic instruments where the 0.050-inch pitch enables routing 10 signals in a connector body measuring only 0.375 inch in length, saving board area compared to 0.100-inch pitch alternatives of equivalent position count.
