Key Features
- 98-position dual-row layout at 0.050-inch (1.27 mm) pitch delivers twice the pin density of standard 0.100-inch headers for compact high-channel-count interconnects
- Tiger Eye contact design provides reliable spring force and low insertion force mating for repeated connection cycles without contact damage
- Tape-and-reel (TR suffix) packaging supports automated pick-and-place SMT assembly for high-volume PCB production
Applications
The TFC-149-02-F-D-A-K-TR is used in high-density board-to-board and mezzanine interconnects for FPGAs, DSPs, and high-channel-count data acquisition systems where 98 signal lines must pass through a minimal footprint at 0.050-inch pitch. It is well-suited for networking line cards, medical imaging modules, and test equipment backplanes requiring dense and reliable SMT connectors.

Frequently Asked Questions
How does the 0.050-inch pitch of the TFC-149-02-F-D-A-K-TR compare to standard header pitches for dense designs?
The 0.050-inch (1.27 mm) pitch is half the width of a standard 0.100-inch (2.54 mm) pitch header, allowing 98 pins to occupy the same board length that a 0.100-inch connector would need for only 49 pins. This density advantage is critical in FPGA mezzanine boards and data-acquisition systems with many parallel signal lines and limited PCB area.
What makes the Tiger Eye contact design in the TFC-149-02-F-D-A-K-TR suitable for repeated mating cycles?
The Tiger Eye contact geometry uses a controlled spring beam that maintains consistent normal force across hundreds of mating cycles without permanent deformation. This ensures stable contact resistance below a few milliohms per pin over the connector's rated life, which is important for modular test fixtures, field-replaceable daughter cards, and reconfigurable signal routing boards.
For a 98-channel FPGA I/O expansion board, what assembly advantages does the TFC-149-02-F-D-A-K-TR offer?
The TFC-149-02-F-D-A-K-TR's tape-and-reel packaging enables fully automated SMT pick-and-place placement, and its 1.27 mm pitch footprint fits within standard FPGA mezzanine form factors. By routing 98 signals through a single dual-row connector instead of multiple smaller headers, designers reduce assembly steps, improve signal grouping, and lower the risk of miswiring in high-pin-count I/O expansion designs.
