Key Features
- Tiger Eye System with shrouded design ensuring positive mating alignment and robust board-to-board connection reliability
- Gold (10 µin) over nickel (50 µin) contact finish on mating surfaces for superior corrosion resistance and low contact resistance
- Phosphor bronze contacts with tin-over-nickel termination finish supporting reliable solder joint formation in board stacking applications
Applications
The TFC-125-02-L-D-A is engineered for high-reliability board stacking applications in industrial, communications, and embedded computing systems requiring secure, keyed mating between PCBs. Its Tiger Eye shroud system prevents misalignment during mating, protecting the 250-position dual-row contacts in dense stacked assemblies. The gold contact finish ensures long service life in environments subject to repeated connect-and-disconnect cycles.

Frequently Asked Questions
What contact finish does the TFC-125-02-L-D-A use for mating reliability?
The TFC-125-02-L-D-A features gold (10 µin) plating over nickel (50 µin) on the mating contacts, made from phosphor bronze base material. This finish combination delivers excellent corrosion resistance and stable low contact resistance across many mating cycles, which is essential for board stacking connectors in industrial and communications equipment.
How does the Tiger Eye system in the TFC-125-02-L-D-A improve assembly reliability?
The Tiger Eye system is SAMTEC's polarized, shrouded design that guides mating boards into precise alignment before the contacts engage. This prevents mis-mating across the 250 positions in the 2.625-inch body, reducing the risk of bent pins or incomplete connections during initial PCB assembly or field servicing.
In which board stacking configurations can the TFC-125-02-L-D-A be deployed?
The TFC-125-02-L-D-A is a male, dual-row board stacking connector with a 0.225-inch body breadth and 2.625-inch body length, suitable for parallel stacked PCB configurations in communications systems, FPGA carrier boards, and industrial controllers. Its 250-position layout enables routing of high-signal-count parallel buses between boards in a single connector body.
