What are the key features of TFC-121-02-L-D-A?
- 42-position dual-row 0.050" pitch Tiger Eye terminal strip delivering high signal density in a narrow PCB footprint
- Long tail (L) contact style for secure wire wrapping or press-fit board termination with increased mechanical hold strength
- Cost-effective Tiger Eye design allowing high-count 42-position connectors without the premium cost of larger-pitch alternatives
What is TFC-121-02-L-D-A used for?
TFC-121-02-L-D-A is used in high-density signal routing for computing modules, FPGA carrier boards, and industrial control systems where 42 signals must be routed in a minimal PCB area using the 0.050-inch pitch standard. Its dual-row layout halves the connector length compared to single-row alternatives, freeing valuable board real estate. The Tiger Eye cost-effective series is favored for commercial volume production where reliable signal connections at competitive cost are required.

Frequently Asked Questions
How many positions does TFC-121-02-L-D-A support, and how does 0.050-inch pitch help save PCB space?
TFC-121-02-L-D-A supports 42 positions in a dual-row layout at 0.050-inch (1.27 mm) pitch. Compared to a standard 0.100-inch pitch connector, the 0.050-inch pitch reduces the connector length by approximately 50% for the same signal count. This is essential in compact FPGA carrier boards and multi-channel data acquisition systems where 42 signals need to exit the PCB edge with minimal connector footprint.
What does the L (long tail) designation mean in TFC-121-02-L-D-A, and in what assembly scenarios is it preferred?
The L designation indicates a long tail contact length, which provides extra pin length beyond the PCB surface for wire wrapping, hand-soldering, or press-fit assembly into daughter card sockets. Long tails also improve solder fillet formation during wave soldering of 42-position connectors, reducing the risk of cold joints at high pin counts. This option is preferred in prototyping environments or when the PCB stack-up requires extended pin clearance below the board.
How does TFC-121-02-L-D-A compare in cost and application to higher-density SAMTEC connectors for 42-signal designs?
TFC-121-02-L-D-A is part of SAMTEC's Tiger Eye cost-effective series, which offers 42 positions at 0.050-inch pitch with standard gold or tin plating at lower cost than high-reliability series using 15-30 µin gold on all surfaces. For commercial computing, instrumentation, or telecom applications requiring moderate mating cycle counts (typically below 500 cycles) and cost control in volume production, TFC-121-02-L-D-A provides an efficient 42-pin solution without the premium pricing of ruggedized alternatives.
