Key Features
- 76-position dual-row configuration at 0.050" (1.27 mm) pitch delivers high-density signal routing in minimal PCB area
- Tiger Eye contact design provides reliable spring-loaded mating force for consistent low-resistance connections over repeated cycles
- Tape-and-reel (TR) packaging enables automated pick-and-place assembly for high-volume SMD manufacturing
- Cost-effective terminal strip design lowers BOM cost compared to premium fine-pitch connectors while maintaining reliable signal integrity
Applications
The TFC-138-02-FM-D-A-K-TR is suited for high-density board-to-board signal interconnects in embedded computing modules, communication boards, and data acquisition systems where up to 76 signal lines must be routed across a 0.050" pitch footprint. Its tape-and-reel packaging supports automated SMT assembly in high-volume production environments. The fine 1.27 mm pitch makes it a strong choice for compact industrial and test equipment designs that require dense multi-signal connectivity.

Frequently Asked Questions
How many signal positions does the TFC-138-02-FM-D-A-K-TR provide and at what pitch?
The TFC-138-02-FM-D-A-K-TR provides 76 positions in a dual-row layout at 0.050" (1.27 mm) pitch, giving 38 pins per row. This fine pitch allows dense signal routing in a compact PCB footprint, making it suitable for applications requiring 38 or more parallel signal lines within a constrained board area.
What manufacturing advantage does the tape-and-reel (TR) suffix provide for the TFC-138-02-FM-D-A-K-TR?
The -TR suffix indicates tape-and-reel packaging, which allows the TFC-138-02-FM-D-A-K-TR to be loaded into automated pick-and-place equipment for high-volume SMD assembly. This packaging format eliminates manual placement errors and is compatible with standard 8 mm to 24 mm carrier tape feeds used in most PCB assembly lines producing hundreds to thousands of boards per day.
In which system-level designs is TFC-138-02-FM-D-A-K-TR an appropriate replacement for a ribbon cable or FPC connector?
The TFC-138-02-FM-D-A-K-TR can replace FPC connectors or ribbon cable assemblies in rigid board-to-board scenarios where 76 signal lines need to cross between two PCBs separated by minimal height. Its 0.050" (1.27 mm) pitch footprint is more compact than standard 0.100" pitch ribbon cable connectors, reducing inter-board connection width by approximately 50% while maintaining reliable signal integrity for digital and low-voltage analog signals.
How does the SAMTEC Tiger Eye contact technology in TFC-138-02-FM-D-A-K-TR improve reliability compared to standard stamped contacts?
SAMTEC's Tiger Eye contacts use a dual-beam spring design that maintains consistent normal force over thousands of mating cycles, providing contact resistance typically below 20 mΩ. This outperforms simple stamped single-beam contacts that can relax over repeated insertions, which is especially important in test and measurement or field-replaceable module applications where connectors are mated and unmated frequently.
