Key Features
- 84-position dual-row 0.050 inch (1.27 mm) pitch configuration delivers high signal density in a compact terminal strip for cost-sensitive mezzanine and board stacking designs
- Tiger Eye dual-beam wiping contact geometry provides reliable low-resistance mating under normal forces consistent across all 84 positions, minimizing signal loss
- Cost-effective TFC series construction maintains SAMTEC Tiger Eye contact reliability while reducing unit cost for high-volume board stacking applications
Applications
The TFC-142-02-L-D-A-K is designed for high-density daughter-card and mezzanine board stacking in networking, embedded computing, and industrial automation applications requiring 84 signal channels at 0.050 inch pitch. Its dual-row Tiger Eye contact design delivers reliable electrical performance at a lower cost compared to premium high-reliability series. This makes it a preferred choice for volume production of telecom line cards, single-board computers, and modular instrumentation platforms.

Frequently Asked Questions
How many signal channels does TFC-142-02-L-D-A-K provide and at what pitch?
TFC-142-02-L-D-A-K provides 84 contact positions arranged in a dual-row layout at 0.050 inch (1.27 mm) pitch, with 42 contacts per row. This high signal count in a compact 1.27 mm pitch footprint makes it suitable for complex board-to-board interfaces in networking and embedded computing applications where routing 84 signals in minimal PCB space is essential.
How does TFC-142-02-L-D-A-K balance cost and reliability for volume mezzanine board designs?
The TFC series uses SAMTEC's Tiger Eye dual-beam contact geometry to deliver reliable mating performance at lower manufacturing cost than the premium TFM high-reliability series. Engineers working on cost-sensitive production volumes of 84-position 0.050 inch pitch board stacking interconnects can use TFC-142-02-L-D-A-K to achieve consistent contact resistance and adequate mating cycle life without the price premium of full high-reliability specifications.
What does the -A-K suffix on TFC-142-02-L-D-A-K indicate about the connector's mounting or retention features?
In SAMTEC's naming convention, the -A suffix typically indicates an alternative pin or contact option, while -K denotes a retention or locking feature that prevents the mated connector from disengaging under vibration or accidental pull. For an 84-position 0.050 inch pitch connector used in rack-mounted telecom or industrial modules, this retention feature is important for maintaining signal continuity under mechanical stress.
In a networking line card design, when would TFC-142-02-L-D-A-K be selected over a 2.00 mm pitch connector for the same 84-signal interface?
At 0.050 inch (1.27 mm) pitch, TFC-142-02-L-D-A-K requires less than half the board edge length compared to a 2.00 mm pitch 84-position connector (approximately 54 mm vs. 84 mm for a single-row equivalent). This reduction in connector footprint frees board space for high-speed differential pairs and power planes on a constrained line card PCB, making the 1.27 mm pitch TFC series the natural choice when every millimeter of board width counts.
