Key Features
- 18-position dual-row male terminal strip at 0.050 inch pitch enabling high-density board stacking in compact designs
- Tiger Eye contact technology with tin over nickel barrier finish for reliable mating and corrosion resistance
- Tape and reel (-TR) packaging supporting automated pick-and-place assembly in high-volume production environments
Applications
The TFC-109-02-L-D-K-TR is designed for cost-effective board-to-board and mezzanine stacking in consumer electronics, industrial control, and embedded computing applications requiring 18-position dual-row interconnects at 0.050 inch pitch. Its square pin male contact style interfaces reliably with matching socket strips, enabling modular PCB system architectures in space-constrained enclosures. This terminal strip is commonly used in development boards, expansion modules, and low-profile daughtercard designs where standard 1.27 mm pitch connectors are required.

Frequently Asked Questions
How many positions and what pitch does TFC-109-02-L-D-K-TR provide for board stacking?
The TFC-109-02-L-D-K-TR is an 18-position dual-row terminal strip with a 0.050 inch (1.27 mm) pitch. This configuration provides 9 pins per row in a compact rectangular footprint, making it well suited for high-density board-to-board stacking interconnects in consumer electronics and embedded system designs.
What contact finish does TFC-109-02-L-D-K-TR use and how does it affect mating reliability?
The TFC-109-02-L-D-K-TR uses tin over nickel barrier contact finish on the termination side, providing good corrosion resistance for board stacking applications. Tin-finished contacts are compatible with standard solder reflow and wave soldering at typical peak temperatures of 260°C, and the nickel barrier prevents copper diffusion for long-term contact integrity across 18 pins.
Is TFC-109-02-L-D-K-TR packaged for automated SMT assembly and what reel options are available?
Yes, the TFC-109-02-L-D-K-TR suffix (-TR) indicates tape and reel packaging, which is fully compatible with automated pick-and-place SMT assembly machines. This packaging option supports high-volume PCB manufacturing lines and eliminates manual handling of individual 18-position connector pieces during production.
For which embedded or modular computing designs is TFC-109-02-L-D-K-TR the preferred interconnect solution?
The TFC-109-02-L-D-K-TR is preferred in modular embedded computing designs such as Arduino-compatible expansion shields, development boards, and mezzanine daughtercards where a cost-effective 18-position, 0.050 inch pitch dual-row male header is needed. Its compact 0.575 inch body length and Tiger Eye contact technology enable reliable signal connections across stacked PCB modules.
