What are the key features of TFC-142-02-LM-D-A?
- 84-position dual-row terminal strip at 0.050" (1.27 mm) pitch offering one of the highest contact counts in the cost-effective Tiger Eye terminal strip series
- Tiger Eye contact technology provides superior normal force compliance and reliable electrical continuity across repeated mating and unmating cycles in demanding environments
- Cost-effective design reduces interconnect BOM cost while maintaining SAMTEC quality and reliability standards for industrial and instrumentation board-to-board applications
What is TFC-142-02-LM-D-A used for?
The TFC-142-02-LM-D-A is used in high-density backplane and mezzanine card interconnects for industrial PLCs, telecom line cards, and modular computing platforms where 84 signal channels must be routed through a single dual-row 0.050" pitch connector. Its Tiger Eye contact technology ensures reliable electrical performance across many board insertion cycles in field-serviceable equipment. Engineers specify it for high-channel-count FPGA carrier boards and data acquisition front ends requiring maximum contact density per unit board length.

Frequently Asked Questions
How does TFC-142-02-LM-D-A compare to lower-position Tiger Eye terminal strips in board space efficiency?
The TFC-142-02-LM-D-A provides 84 positions in a dual-row 0.050" (1.27 mm) pitch layout, fitting 42 contacts per row within a compact board footprint significantly smaller than what multiple lower-count connectors would occupy. This high-density design is more space-efficient than using two or three smaller Tiger Eye strips to achieve the same 84-contact interface, reducing PCB area usage in mezzanine and backplane designs.
What makes the Tiger Eye contact system in TFC-142-02-LM-D-A suitable for field-replaceable board applications?
The Tiger Eye contact system in the TFC-142-02-LM-D-A maintains consistent normal force across all 84 positions after repeated insertions, making it reliable for field-replaceable mezzanine boards that undergo dozens of removal and reinstallation cycles. Its contact compliance reduces the risk of intermittent connections at any of the 84 positions due to mechanical wear or thermal cycling from -55°C to +125°C in industrial systems.
For which signal types is the TFC-142-02-LM-D-A's 0.050" pitch most appropriate?
The TFC-142-02-LM-D-A at 0.050" (1.27 mm) pitch is best suited for DC and low-frequency digital signals up to several hundred MHz per channel, where controlled impedance matching is not required. Its 84-position dual-row layout is ideal for GPIO bus routing, power rail distribution, and parallel data bus interconnects in FPGA systems, industrial controllers, and data acquisition modules that prioritize high contact count over high-speed signal integrity.
