What are the key features of TFC-139-02-FM-D-A-K?
- 78-position dual-row FM (female-male) configuration at 0.050" (1.27 mm) pitch supports 39 circuits per row in a compact connector body
- Tiger Eye dual-beam contacts maintain contact resistance below 20 mΩ over 200+ mating cycles for long-term signal reliability
- Cost-effective Tiger Eye terminal strip design lowers per-circuit cost at volume without sacrificing mating durability or electrical performance
What is TFC-139-02-FM-D-A-K used for?
The TFC-139-02-FM-D-A-K is applied in high-channel embedded computing boards, FPGA mezzanine modules, and industrial I/O expansion cards requiring 78 reliable signal paths within a minimal PCB footprint. The 1.27 mm pitch female-male dual-row layout provides board-to-board connectivity at reduced stack height compared to discrete pin headers, making it attractive for compact backplane and daughter-card assemblies. Its Tiger Eye contact reliability makes it dependable across the full industrial temperature range.

Frequently Asked Questions
Which dense board-level assemblies are a good fit for TFC-139-02-FM-D-A-K?
TFC-139-02-FM-D-A-K fits high-density board interconnects that require 78 pins and a dual-row Tiger Eye terminal-strip architecture.
How does its pitch influence PCB layout and mating selection?
The connector family uses a 0.050 inch pitch, so designers should check the 78 pins, row orientation, and mating socket footprint together.
What should buyers verify before replacing this TFC part with another SAMTEC option?
Buyers should preserve the 78 pins, female-male contact style, keying option, and board stack requirements when comparing alternate SAMTEC orderable numbers.
