What are the key features of TFC-140-02-L-D-A-K?
- 80-position dual-row male pin strip on 0.050" (1.27mm) pitch for high-density board stacking
- Tiger Eye cost-effective design reduces BOM cost for high-volume mezzanine connector applications
- Peg board-mount option and 2.125-inch body provide mechanical stability during assembly and in-service vibration
What is TFC-140-02-L-D-A-K used for?
The TFC-140-02-L-D-A-K is a board-stacking terminal strip designed for mezzanine and daughter-card interconnect in industrial computing, embedded systems, and communication equipment. Its 80-position dual-row configuration on a 1.27mm pitch delivers high signal density in a 2.125-inch body, making it practical for FPGA carrier boards, backplane modules, and DSP cards. The cost-effective Tiger Eye series is chosen when high pin count and mechanical reliability are required without the premium cost of high-speed or filtered connector variants.

Frequently Asked Questions
How many contacts does the TFC-140-02-L-D-A-K provide, and on what pitch?
The TFC-140-02-L-D-A-K provides 80 positions arranged in 2 dual rows on a 0.050-inch (1.27mm) pitch, yielding 160 individual contact points. This density is appropriate for mezzanine board interfaces where processor, FPGA, or memory module connections must be concentrated in a body only 2.125 inches long, keeping the overall PCB real estate usage low.
What is the Tiger Eye series, and when is TFC-140-02-L-D-A-K a better choice than Samtec's high-speed alternatives?
Samtec Tiger Eye TFC connectors are a cost-effective board-stacking family using square-pin socket contacts instead of the more expensive BeamBand or Tiger Beam contacts found in high-speed series. TFC-140-02-L-D-A-K is the right choice when signal frequencies stay below 1 GHz and budget is the primary driver—such as power distribution, GPIO banks, or low-speed parallel bus connections—where paying for impedance-controlled contacts would add unnecessary cost per board.
Does the peg board-mount feature on the TFC-140-02-L-D-A-K help with vibration resistance in field-deployed equipment?
Yes. The peg (PEG) board-mounting option on the TFC-140-02-L-D-A-K adds plastic retention pegs that lock the connector body to the PCB before soldering, preventing movement during reflow and improving resistance to vibration in deployed assemblies. This is particularly useful for industrial control panels and transportation electronics where PCBs may experience continuous low-frequency vibration that could lift an unsupported 2.125-inch connector before solder joints cure.
