What are the key features of TFC-142-02-FM-D-A-K-TR?
- 84-position dual-row Tiger Eye contacts at 0.050" (1.27 mm) pitch achieve ultra-high signal density, routing 84 channels in approximately 2.15 inches of board length
- Floating mount (-FM) design accommodates up to 0.5 mm of PCB-to-PCB misalignment, reducing stress on solder joints in board stacking and mezzanine applications
- Keyed (-K) polarization and tape-and-reel (-TR) packaging combine to prevent mismating errors and enable high-speed automated pick-and-place assembly on fine-pitch production lines
What is TFC-142-02-FM-D-A-K-TR used for?
The TFC-142-02-FM-D-A-K-TR is engineered for ultra-high-density mezzanine board interconnects and cable-to-board interfaces in embedded computing systems, network switching cards, and high-channel-count data acquisition modules. Its 84-position floating-mount design absorbs PCB misalignment tolerances of up to 0.5 mm, making it ideal for board stacking configurations where dimensional tolerances between mating PCBs cannot be guaranteed within tight limits. The keyed tape-and-reel format supports fully automated assembly of complex multi-board systems in telecommunications infrastructure and industrial edge computing platforms.

Frequently Asked Questions
How does the floating mount (-FM) option on the TFC-142-02-FM-D-A-K-TR reduce mechanical stress during PCB stacking assembly?
The floating mount design of the TFC-142-02-FM-D-A-K-TR allows the 84-position connector body to float up to 0.5 mm laterally relative to its PCB footprint. This compliance absorbs misalignment between two stacked PCBs during mating, preventing solder joint fatigue on fine-pitch 0.050" pads where even 0.2 mm of lateral force would exceed joint shear limits across 84 positions.
What board length does the 84-position TFC-142-02-FM-D-A-K-TR occupy, and how does it compare to a 0.100" pitch equivalent?
At 0.050" (1.27 mm) pitch over 42 positions per row, the TFC-142-02-FM-D-A-K-TR spans approximately 2.15 inches (54 mm) in body length. An equivalent 84-position dual-row connector at standard 0.100" pitch would require approximately 4.3 inches (109 mm), meaning the fine-pitch variant saves over 55 mm of PCB real estate—a critical advantage in blade servers and compact industrial compute modules.
Which high-channel-count system designs benefit most from deploying the TFC-142-02-FM-D-A-K-TR over multiple lower-position-count connectors?
Designs requiring 64 or more simultaneous signal paths—such as 64-bit parallel memory buses, 80-channel sensor array interfaces, or 84-channel FPGA I/O breakout boards—benefit most from a single 84-position TFC-142-02-FM-D-A-K-TR rather than multiple smaller connectors. Using one 84-position connector instead of two 42-position headers eliminates an additional keying verification step, reduces solder joint count by consolidating terminations, and simplifies PCB routing by keeping all 84 signals within a single 2.15-inch zone.
