What are the key features of TFC-146-02-F-D-A?
- 92-position dual-row terminal strip at 0.050-inch (1.27 mm) pitch, delivering 46 contacts per row for maximum-density PCB signal termination
- Tiger Eye contact design creates a self-wiping interface that maintains consistent low-resistance connection across all 92 positions after repeated insertions
- Cost-effective construction keeps BOM cost low compared to premium connectors while maintaining precise 0.050-inch pitch geometry for reliable mating
What is TFC-146-02-F-D-A used for?
The TFC-146-02-F-D-A is engineered for very high-density interconnect requirements in large line cards, FPGA development boards, and multi-channel data acquisition systems that need 92 signal positions in a compact through-hole footprint. Its Tiger Eye contacts and cost-effective design make it practical for production-volume PCB assemblies in telecom, industrial automation, and embedded computing where large pin counts and budget efficiency are both priorities.

Frequently Asked Questions
What is the total position count and per-row contact count of the TFC-146-02-F-D-A at 0.050-inch pitch?
The TFC-146-02-F-D-A provides 92 positions total in a dual-row configuration, with 46 contacts per row at a 0.050-inch (1.27 mm) pitch. This places all 92 signal lines within approximately a 2.3-inch body length, making it one of the highest-density through-hole terminal strips in the SAMTEC Tiger Eye TFC series.
For an FPGA board requiring 92 GPIO connections, how does the TFC-146-02-F-D-A help manage PCB routing complexity?
By consolidating 92 signal positions into a dual-row 0.050-inch pitch footprint roughly 2.3 inches long, the TFC-146-02-F-D-A reduces the board area needed for high pin-count GPIO headers compared to 0.100-inch alternatives, which would require nearly twice the length. This compact arrangement simplifies high-density routing in FPGA breakout and prototyping boards.
Why might a cost-sensitive industrial control design select the TFC-146-02-F-D-A instead of a higher-spec 92-position connector?
The TFC-146-02-F-D-A is positioned as a cost-effective alternative for applications where mating cycles are limited and environmental stresses are moderate, avoiding the cost premium of full-gold or high-cycle-rated connectors for all 92 positions. For industrial control panels assembled in volume, this choice can yield meaningful per-unit savings while the Tiger Eye wiping contact still provides dependable signal continuity.
