What are the key features of TFC-125-02-L-D-A-K-TR?
- 50-position dual-row board stacking connector on ultra-fine 0.050 inch (1.27 mm) pitch for space-constrained designs
- Tiger Eye contact design provides reliable wiping action and low insertion force for high-cycle mating
- Tin-over-nickel termination finish on male contacts ensures reliable solderability and long-term corrosion resistance
- RoHS-compliant and JESD-609 e3 rated for lead-free assembly processes
- Tape-and-reel (TR) packaging supports automated high-volume SMT pick-and-place assembly
What is TFC-125-02-L-D-A-K-TR used for?
The TFC-125-02-L-D-A-K-TR is designed for compact board-to-board stacking applications in embedded computing modules, FPGA mezzanine cards, and high-density I/O expansion boards where the 0.050 inch pitch allows 50 connections in a footprint roughly half the width of a 0.100 inch pitch equivalent. It is widely used in data acquisition systems, network switch line cards, and RF module interconnects requiring reliable dual-row stacking with controlled impedance at fine pitch. The connector is also adopted in industrial PLC backplanes, robotics control boards, and medical device PCB assemblies where space efficiency and manufacturing automation are both critical.

Frequently Asked Questions
What pitch and position count does TFC-125-02-L-D-A-K-TR provide for board stacking?
TFC-125-02-L-D-A-K-TR features a 0.050 inch (1.27 mm) pitch in a dual-row configuration with 50 total positions (25 per row), enabling high-density board stacking in compact PCB designs where standard 0.100 inch pitch connectors would require twice the board edge length.
What is the Tiger Eye contact design in TFC-125-02-L-D-A-K-TR and how does it affect mating reliability?
The Tiger Eye contact geometry features a bifurcated spring beam design that provides a wiping action during mating, displacing oxides and debris from the mating contact surface. This dual-beam contact achieves more than 2 independent contact points per pin, significantly improving connection reliability in vibration-prone environments compared to single-beam contact designs.
How does TFC-125-02-L-D-A-K-TR compare to a 0.100 inch pitch connector for the same 50-signal interface?
A 0.100 inch pitch dual-row connector for 50 positions would span approximately 1.30 inches in board length, while TFC-125-02-L-D-A-K-TR at 0.050 inch pitch occupies only about 0.65 inches, saving roughly 50% of the PCB edge, which is critical in mezzanine cards and stackable module designs where every millimeter of board length has a cost implication.
Is TFC-125-02-L-D-A-K-TR suitable for lead-free soldering and what certifications support it?
Yes, TFC-125-02-L-D-A-K-TR is RoHS compliant and carries JESD-609 code e3, confirming its suitability for lead-free soldering processes with peak reflow temperatures up to 260°C. The tin-over-nickel contact termination finish is specifically designed to be compatible with standard lead-free SAC305 solder alloys used in modern PCB assembly.
