What are the key features of TFC-140-02-L-D-K-TR?
- 80-position dual-row 0.050" pitch layout achieves very high pin density in a 2.125 inch by 0.225 inch PCB footprint
- 15 µin gold mating contacts on phosphor bronze base metal deliver low contact resistance and extended cycle life
- Tin-over-nickel barrier termination finish combined with tape-and-reel packaging supports automated SMT high-volume production
What is TFC-140-02-L-D-K-TR used for?
The TFC-140-02-L-D-K-TR is used in high-density board-to-board and board-to-cable interconnect applications in telecommunications equipment, servers, and data acquisition systems where 0.050 inch pitch maximizes channel count in a constrained PCB area. Its 80-position dual-row configuration with gold mating contacts accommodates mixed signal, power, and control lines on a single connector. The tape-and-reel format enables automated placement in high-volume SMT assembly of networking and computing modules.

Frequently Asked Questions
How dense is the TFC-140-02-L-D-K-TR, and what board area does an 80-position connector occupy?
The TFC-140-02-L-D-K-TR uses a 0.050 inch pitch dual-row layout, fitting 80 positions into a 2.125 inch body length and 0.225 inch breadth footprint, achieving roughly 37 positions per inch — approximately twice the pin density of standard 0.100 inch pitch connectors.
What contact finish does the TFC-140-02-L-D-K-TR use, and how does it affect reliability in high-cycle applications?
The mating contacts are plated with 15 µin (micro-inch) gold over phosphor bronze, providing low and stable contact resistance across hundreds of mate and unmate cycles. This finish is suitable for applications requiring reliable signal integrity in instrumentation and test equipment subject to repeated connection and disconnection.
Is the TFC-140-02-L-D-K-TR suitable for automated SMT assembly in a 1000-unit production run?
Yes, the TR suffix indicates tape-and-reel packaging, and the surface-mount compatible termination with tin-over-nickel barrier allows standard reflow soldering in automated SMT lines. For a 1000-unit run, each connector provides 80 connections per placement cycle, reducing total connector assembly time compared to through-hole alternatives requiring manual insertion.
