What are the key features of TFC-139-02-F-D-A-K?
- 78-position, 2-row male header at 1.27 mm (0.050 inch) pitch provides a high contact count in a compact terminal strip form factor
- Tiger Eye contact design with polarization key (-K option) prevents mis-mating and ensures reliable signal continuity across all 78 positions
- Cost-effective TFC series construction makes this 78-position strip suitable for high-volume production designs where premium plating is not required
What is TFC-139-02-F-D-A-K used for?
The TFC-139-02-F-D-A-K is ideal for high-density board-to-board and backplane connections in industrial control systems, embedded computing modules, and test equipment. Its 78-position, 2-row layout at 1.27 mm pitch supports a large number of signal and power lines within a minimal board footprint. The polarization key reduces assembly errors and is particularly valuable in applications where multiple similar connectors are populated on the same PCB.

Frequently Asked Questions
What is the contact count and pitch of the TFC-139-02-F-D-A-K, and how is it arranged?
The TFC-139-02-F-D-A-K has 78 positions in a 2-row male configuration at 1.27 mm (0.050 inch) pitch, placing 39 contacts per row in a rectangular terminal strip layout for high-density PCB board-to-board interconnect applications.
How does the polarization key (-K) on this Samtec terminal strip prevent assembly errors on a populated PCB?
The -K polarization post creates an asymmetric mechanical feature that blocks 180-degree mis-insertion, which is critical when multiple 78-position, 1.27 mm pitch connectors occupy the same board and could otherwise be confused during hand or automated assembly, preventing costly rework.
For which industrial or embedded computing designs is the TFC-139-02-F-D-A-K a practical connector choice?
This 78-position, 2-row, 1.27 mm pitch terminal strip suits industrial automation backplanes, data acquisition front-end cards, and SBC mezzanine interfaces that need a large signal count with an operating temperature range of -55°C to +125°C and cost-effective construction for moderate production volumes.
When would TFC-139-02-F-D-A-K be selected over a higher-specification Samtec connector series?
Designers choose the TFC cost-effective terminal strip over premium Samtec series when the design needs 78 positions at 1.27 mm pitch but does not require high-cycle mating life (above 100 cycles) or tight impedance control, making it well suited for signal routing in low-to-medium cycle-count applications with budget constraints.
