Key Features
- 56 positions in a dual-row 0.050" (1.27 mm) pitch layout, delivering mid-high density signal connectivity in a compact form factor
- Tiger Eye low-insertion-force contact design maintains consistent normal force across all 56 positions for reliable mating
- Cost-effective terminal strip construction reduces BOM cost for applications not requiring premium shielding or high-speed geometry
Applications
The TFC-128-02-L-D-A addresses mid-to-high density board-to-board interconnect needs in embedded computing modules, motor control boards, and industrial interface cards requiring 56 signals on a 0.050" pitch. Its cost-effective Tiger Eye design makes it practical for production designs where signal integrity at moderate frequencies is sufficient and budget constraints favor lower-cost connector alternatives.

Frequently Asked Questions
How many contacts and in what pitch does the TFC-128-02-L-D-A connector provide?
The TFC-128-02-L-D-A provides 56 total contact positions arranged in 2 rows on a 0.050" (1.27 mm) pitch. This mid-density dual-row configuration routes 56 independent signal lines between boards within a compact PCB footprint, making it practical for embedded modules, sensor platforms, and industrial control interfaces.
How does the 56-position TFC-128-02-L-D-A compare to the 54-position TFC-127-02-LM-D-A-K-TR for similar applications?
The TFC-128-02-L-D-A offers 56 positions versus 54 positions on the TFC-127-02-LM-D-A-K-TR, both sharing the 0.050" (1.27 mm) dual-row pitch. The 2 additional contacts on the TFC-128-02-L-D-A can accommodate an extra pair of signals, such as a differential pair or additional control lines, without requiring a larger-pitch or wider connector footprint.
What board-to-board signal routing scenarios best suit the TFC-128-02-L-D-A?
The TFC-128-02-L-D-A is best suited for scenarios requiring 56 mixed-signal lines such as parallel data buses of 32 bits with control and address signals, multi-channel ADC interfaces, or motor drive daughter cards connecting to a main controller PCB. At 0.050" pitch, 56 signals can be routed in roughly 1.4 inches (35 mm) of connector length, enabling compact module-to-carrier designs.
What procurement considerations apply when sourcing the TFC-128-02-L-D-A in volume?
When sourcing the TFC-128-02-L-D-A at volumes above 500 units, buyers typically find cost-effective Tiger Eye terminal strips available with standard lead times from authorized SAMTEC distributors. The 56-position count falls within a common size range, and the absence of a tape-and-reel designation on this variant means it ships in trays or cut tape, which may require manual or semi-automated placement rather than fully automated pick-and-place assembly.
