Key Features
- 34-position dual-row layout on 1.27 mm (0.050 inch) pitch delivers high circuit density in a 24.8 mm x 5.7 mm body for space-constrained board-to-board designs
- Gold (3 µin) contact finish on phosphor bronze contacts ensures low contact resistance and high mating cycle reliability for test and industrial applications
- Tiger Eye cost-effective design provides reliable signal integrity across all 34 positions while minimizing connector cost compared to premium high-pin-count alternatives
Applications
The TFC-117-02-F-D-A is used in board-to-board interconnects, PCB test point arrays, and compact data acquisition modules where 34 signal or power lines must be routed between boards in a 1.27 mm pitch envelope. Its gold-plated contacts and phosphor bronze construction make it suitable for measurement instruments, RF evaluation boards, and industrial fieldbus interface cards requiring reliable low-insertion-force mating cycles.

Frequently Asked Questions
What pitch and position count does the SAMTEC TFC-117-02-F-D-A provide, and how does this affect routing density?
The TFC-117-02-F-D-A features 34 positions on a 1.27 mm (0.050 inch) pitch in a dual-row arrangement, fitting 34 circuits within a body length of approximately 24.8 mm. This is half the pitch of 2.54 mm standard headers, effectively doubling circuit density per millimeter of PCB edge and allowing compact board stacking in data acquisition, test, and communication modules.
What contact material and finish does the TFC-117-02-F-D-A use, and why is that important for reliability?
The connector uses phosphor bronze contacts with gold plating (3 µin) on the mating surfaces and tin with a nickel barrier on the termination side. Gold mating contacts provide corrosion resistance and stable contact resistance below 20 milliohms over hundreds of mating cycles, while the nickel barrier beneath the tin termination prevents tin whisker growth and improves solder joint reliability during reflow assembly.
In which board-level interconnect scenarios is the TFC-117-02-F-D-A a more cost-effective choice than higher-grade alternatives?
For evaluation boards, prototype test fixtures, and low-to-medium mating cycle applications (under 500 cycles), the Tiger Eye TFC series offers gold mating contacts at a lower cost per position than high-cycle board-to-board connectors rated for 1000 or more cycles. A 34-position dual-row strip at 1.27 mm pitch in this family costs significantly less than equivalent-count micro-pitch array connectors while still supporting signal rates above 1 Gbps for standard LVDS and CMOS interfaces.
