Key Features
- 26-position dual-row board stacking connector on 1.27 mm (0.050") pitch enabling high-density PCB-to-PCB interconnection in tight spaces
- Tiger Eye contact design provides wiping action against the mating socket to maintain low contact resistance over thousands of mating cycles
- Through-hole peg mounting option for mechanical retention during soldering and in high-vibration board stack assemblies
Applications
The TFC-113-02-F-D-A is ideal for compact board-stacking assemblies in portable medical devices, test instruments, and miniaturized industrial controllers where a 1.27 mm pitch dual-row header minimizes stack footprint while carrying 26 signal lines. Its Tiger Eye contacts support reliable signal integrity for SPI, I2C, and parallel bus routing across stacked PCBs with low insertion loss at frequencies up to several hundred MHz. The peg mounting ensures mechanical stability in vibration-prone environments such as robotics platforms and avionics test equipment.

Frequently Asked Questions
How many signal lines does the TFC-113-02-F-D-A support and how are they arranged across its dual-row body?
The TFC-113-02-F-D-A provides 26 positions in 2 rows of 13 contacts on a 1.27 mm (0.050") pitch, giving a total connector body length of approximately 19.7 mm. This layout allows 26 individual signal or power connections in a footprint smaller than most 2.54 mm pitch equivalents, saving critical board space in multi-board stack designs.
What mechanical advantage does the peg mounting option provide when soldering the TFC-113-02-F-D-A on a PCB?
The board-mounting pegs snap into matching 1.0 mm diameter PCB holes, holding the connector in place with approximately 2 N of retention force during wave or reflow soldering. This prevents connector shift or tilt when the solder paste reflows, avoiding the 0.1–0.2 mm pin-to-pad misalignment that can cause bridging or open joints on 1.27 mm pitch contacts.
What is the current and voltage rating per contact on the TFC-113-02-F-D-A for mixed signal and power routing?
SAMTEC TFC series contacts on 1.27 mm pitch are rated at approximately 1 A per contact at up to 250 V AC/DC. In a mixed-signal design, a typical allocation uses 2 contacts in parallel for a 2 A power rail, while the remaining 24 contacts carry 3.3 V or 1.8 V logic signals at currents well below the 1 A per-pin limit.
When is the TFC-113-02-F-D-A a cost-effective alternative to fine-pitch FFC or FPC cable connectors in a board-to-board link?
The TFC-113-02-F-D-A is the lower-cost option when the board-to-board distance is fixed (e.g. 2 mm to 8 mm stacking height) and rigid PCB-to-PCB alignment is maintained by a chassis or standoff. Unlike FFC/FPC connectors requiring flexible cable, the rigid pin-socket mating eliminates cable length tolerances and reduces total BOM count by removing the flex circuit, typically saving 15–30% on connector and cabling cost for stack counts above 1000 units.
