Key Features
- 80-position dual-row configuration at 0.050" (1.27 mm) pitch with 2.125 inch body length delivering very high signal density for FPGA and parallel bus interconnect
- 15 µin gold over phosphor bronze mating contacts with tin over nickel barrier termination ensuring reliable low-resistance connections compatible with lead-free reflow soldering
- Peg board mounting option with kinked lead (K) and tape-and-reel (TR) packaging enabling precise PCB alignment and automated pick-and-place production assembly
Applications
The TFC-140-02-L-D-A-K-TR is well suited for high-density signal routing in FPGA mezzanine boards, parallel data bus backplanes, and compact embedded computing modules requiring 80 connections at 0.050" pitch. Its 2.125 inch body length accommodates dual-row pin grids in server expansion cards, high-speed test fixtures, and telecom line cards where maximizing signal count per connector is a primary design objective. The tape-and-reel packaging and peg mounting simplify volume SMT production with consistent mechanical alignment.

Frequently Asked Questions
What contact pitch and position count does the TFC-140-02-L-D-A-K-TR provide?
The TFC-140-02-L-D-A-K-TR provides 80 positions in a dual-row layout at 0.050" (1.27 mm) pitch, with a 2.125 inch body length. This configuration delivers one of the higher contact counts in the TFC series, making it appropriate for FPGA pin headers, parallel bus interfaces, and high-channel-count data acquisition connectors where both density and board economy are required.
What is the mating contact finish and how does it contribute to connector reliability?
The TFC-140-02-L-D-A-K-TR uses 15 µin gold over phosphor bronze contacts on the mating interface, with tin over nickel barrier on the termination side. The 15 µin gold ensures consistent low contact resistance and corrosion protection across all 80 positions, while the phosphor bronze base provides the spring force needed for secure mechanical retention through hundreds of mate and unmate cycles in board stacking and module replacement scenarios.
How do the peg mounting and kinked lead features aid PCB assembly for the TFC-140-02-L-D-A-K-TR?
The peg (PEG) board mounting option provides a physical locating pin that registers the 80-position connector body precisely to the PCB before soldering, preventing lateral shift during reflow. Combined with the kinked lead (K) termination that grips the PCB surface, the TFC-140-02-L-D-A-K-TR maintains accurate 0.050" pitch alignment across its full 2.125 inch body length, reducing co-planarity issues in automated SMT soldering.
For which cost-sensitive high-density designs is TFC-140-02-L-D-A-K-TR a practical choice over premium board stacking connectors?
The TFC-140-02-L-D-A-K-TR is a practical cost-effective alternative to premium board stacking connectors when 80 dual-row contacts at 0.050" pitch are needed but high-cycle-life or impedance-controlled connector specifications are not mandated. Typical use cases include prototype FPGA carrier boards, industrial PLC expansion modules, and low-to-medium volume embedded computing products where BOM cost reduction matters and signal frequencies remain below 500 MHz.
