Key Features
- 44-position dual-row board-stacking terminal strip on 0.050 inch (1.27 mm) pitch enabling high-density board-to-board interconnect in compact systems
- Peg mounting (PEG) option providing mechanical registration and board-to-board alignment during assembly to improve connector seating accuracy
- Tiger Eye contact geometry delivering reliable wipe action and low-insertion-force mating for repeated board swapping in development and test environments
- Rectangular contact pattern with male square-pin style supporting high-cycle durability in modular computing and instrumentation stacking applications
Applications
TFC-122-02-F-D-A is designed for board-stacking applications in compact embedded systems, FPGA development modules, and high-density signal routing between two parallel PCBs on 0.050 inch pitch. Its 44-position dual-row layout carries up to 44 signal lines in a 1.225 inch body length, making it suitable for replacing larger connectors in space-constrained PCB stacks. The peg mounting feature ensures accurate board alignment during soldering and repeated plug-unplug cycles in modular equipment.

Frequently Asked Questions
How many positions does TFC-122-02-F-D-A provide, and what is the connector pitch?
TFC-122-02-F-D-A is a 44-position dual-row connector on 0.050 inch (1.27 mm) pitch. The body spans 1.225 inches in length and 0.225 inches in breadth, accommodating 22 contacts per row. This fine-pitch layout provides 44 signal lines in roughly half the PCB length required by an equivalent 0.100 inch pitch connector.
What role does the peg mounting feature play in using TFC-122-02-F-D-A for board stacking?
The peg mounting (PEG) option on TFC-122-02-F-D-A provides a physical registration peg that aligns the connector precisely to the mating board's mounting hole during assembly. This is critical on 0.050 inch pitch dual-row connectors where even a 0.1 mm misalignment can cause contact damage or incomplete mating across all 44 positions.
Which SAMTEC mating connector family pairs with TFC-122-02-F-D-A in a board-to-board stack?
TFC-122-02-F-D-A mates with SAMTEC's TFM series 44-position female receptacle on the corresponding 0.050 inch (1.27 mm) pitch. The TFC-TFM stack height can be selected to achieve board-to-board separations ranging from approximately 4 mm to 20 mm, giving designers flexibility for heat spreader clearance or inter-board component height in stacked module designs.
For a design requiring more than 44 signals on a 0.050 inch pitch board stack, which TFC variant would provide higher pin count?
The TFC-140-02 series offers 80 positions on the same 0.050 inch pitch dual-row format, doubling the signal capacity compared to TFC-122-02-F-D-A while maintaining the same 0.225 inch body breadth. For designs needing between 44 and 80 signals, TFC-130-02 (60 positions) or TFC-135-02 (70 positions) variants in the Tiger Eye family cover intermediate pin counts.
