Key Features
- 22-position dual-row male board connector on 0.050 inch (1.27 mm) pitch with compact 0.675 × 0.225 inch body footprint
- 3 µin gold mating contact finish over phosphor bronze ensures low contact resistance and reliable signal integrity for signal frequencies up to several hundred MHz
- Matte tin (Sn) termination finish is compatible with standard lead-free wave soldering and selective soldering processes
- Tiger Eye friction-mate contact geometry provides consistent normal force for tool-free mating and quick rework in prototyping environments
Applications
The TFC-111-02-F-D-A is used in compact embedded module interconnects, sensor interface boards, and test fixture daughter cards where a 22-position 1.27 mm pitch male connector with through-hole vertical mounting is required. Its small 0.675 × 0.225 inch body fits within tight PCB keep-out zones adjacent to other through-hole components. The gold-plated mating contacts ensure reliable connectivity in laboratory, medical, and light industrial applications with moderate insertion cycle requirements.

Frequently Asked Questions
What are the body dimensions and contact finish specifications of the TFC-111-02-F-D-A?
The TFC-111-02-F-D-A has a body length of 0.675 inch, breadth of 0.225 inch, and depth of 0.226 inch. The mating contacts are plated with 3 µin gold over phosphor bronze for low contact resistance, while the termination tails use matte tin finish, which is compatible with lead-free wave soldering and selective soldering processes.
How does the 3 µin gold contact finish in the TFC-111-02-F-D-A affect its reliability compared to tin-finished contacts?
Gold mating contacts, even at 3 µin thickness, resist oxidation and fretting corrosion better than tin contacts in lower-cycle applications. This maintains stable contact resistance below 50 milliohms over the expected insertion cycle life of the TFC series. For signal frequencies up to several hundred MHz, the gold finish minimizes resistive losses that would degrade signal integrity in high-speed digital interfaces.
Which board-to-board or wire-to-board applications benefit most from the TFC-111-02-F-D-A's 1.27 mm pitch 22-position layout?
This connector suits applications where a 16-bit or 20-bit parallel data bus plus power and ground signals must pass through a single 22-position connector, such as sensor front-end boards connecting to a microcontroller carrier card. Embedded camera modules, CAN bus breakout boards, and FPGA prototyping shields with standard 0.050 inch pitch pin headers are common matches for the TFC-111-02-F-D-A male footprint.
How does the TFC-111-02-F-D-A differ from the TFC-111-02-FM-D-A-K-TR variant of the same series?
The TFC-111-02-F-D-A is a through-hole vertical (F) board connector without the keeper (no K suffix) and without tape-and-reel packaging (no TR suffix). The TFC-111-02-FM-D-A-K-TR adds a keeper pin (-K) for mechanical stability during wave soldering and ships in tape-and-reel (-TR) for high-volume SMT lines. Both variants share the same 22-position dual-row 1.27 mm pitch layout and 3 µin gold contact finish.
