Frequently Asked Questions
What is the Tiger Eye system feature on the TFC-120-02-L-D-A and how does it benefit assembly?
The Tiger Eye system is SAMTEC's proprietary shrouded contact design that provides mechanical guidance and protection during board-to-board mating. The shroud aligns the mating receptacle over the 40-position dual-row male contacts, preventing misalignment-induced damage during PCB stack assembly and reducing the risk of bent pins in manual or robotic assembly processes.
What contact finish does the TFC-120-02-L-D-A use and what reliability does it provide?
The TFC-120-02-L-D-A uses gold (10 µin minimum) over nickel (50 µin) on mating surfaces and tin over nickel on termination contacts. Gold plating ensures stable, low contact resistance across hundreds of mating cycles and prevents oxidation in industrial environments, while the nickel barrier prevents tin whisker migration at soldered board terminations.
What are the physical dimensions and position count of the TFC-120-02-L-D-A?
The TFC-120-02-L-D-A has a body length of 2.125 inches and a body breadth of 0.225 inch. It is a dual-row male board stacking connector, providing 20 positions per row for a total of 40 contacts, supporting signal and power routing between stacked PCBs in modular embedded computing and industrial control architectures.
How quickly can the TFC-120-02-L-D-A be procured and what is the lead time?
The TFC-120-02-L-D-A has a factory lead time of approximately 2 weeks and 1 day, which is significantly shorter than many comparable connectors in the market. This short lead time makes it practical for rapid prototyping and low-to-medium volume production ramps without needing extensive forward stocking or long-range procurement planning.
