Key Features
- 92 positions in a dual-row 0.050" (1.27 mm) pitch layout delivering twice the density of standard 0.100" terminal strips in the same board space
- Tiger Eye contact system provides reliable low-insertion-force mating with high cycle life at a cost-effective price point versus gold-plated high-reliability alternatives
- Tape-and-reel packaging (TR suffix) enables automated pick-and-place assembly for high-volume PCB manufacturing with consistent component orientation
Applications
The TFC-146-02-L-D-A-K-TR is used in consumer electronics daughtercard interfaces, mid-range industrial controller boards, and telecommunications line-card assemblies where 92 signal paths are needed at 0.050" pitch with controlled BOM cost. Its Tiger Eye contact design and tape-and-reel packaging support high-throughput automated assembly in volume production environments. Data storage backplanes and network switch cards also use this connector to interconnect processor modules and memory expansion boards at high signal density.

Frequently Asked Questions
What does the Tiger Eye contact system in the TFC-146-02-L-D-A-K-TR offer over standard stamped-and-formed contacts?
SAMTEC's Tiger Eye contact system uses a bifurcated dual-beam contact design that provides two independent contact points per pin, reducing the risk of open circuits from particulate contamination or slight pin misalignment compared to single-beam stamped contacts. This results in more reliable signal connections across 92 positions at 0.050" (1.27 mm) pitch, especially in applications subjected to vibration or repeated mating cycles in industrial or communications equipment.
How does the 0.050" pitch of the TFC-146-02-L-D-A-K-TR reduce PCB connector footprint compared to 0.100" alternatives?
At 0.050" (1.27 mm) pitch with 46 positions per row, the TFC-146-02-L-D-A-K-TR occupies approximately 58 mm of PCB edge length for 92 signals, compared to roughly 116 mm that an equivalent 0.100" (2.54 mm) pitch connector would require. This 50% reduction in connector length frees significant PCB real estate on dense boards such as network line cards, FPGA carrier boards, and data storage backplanes.
What assembly method does the TFC-146-02-L-D-A-K-TR support and how does the TR suffix indicate packaging?
The TR suffix on the TFC-146-02-L-D-A-K-TR designates tape-and-reel packaging, confirming the connector is supplied on a continuous reel compatible with automated pick-and-place SMT assembly lines. This packaging format is essential for high-volume PCB manufacturing, ensuring each of the 92-position dual-row connectors is oriented consistently for robotic placement and reflow soldering at temperatures up to 260°C.
How does the TFC-146-02-L-D-A-K-TR balance cost and performance for high-volume production designs?
The TFC series Tiger Eye design is SAMTEC's cost-optimized alternative to premium gold-plated socket strips such as the SFM or SFS series, delivering reliable 92-position connectivity at 0.050" (1.27 mm) pitch with a lower per-unit cost suitable for consumer and mid-range industrial applications. While premium connectors may offer 50 µin gold plating and extended mating cycles beyond 500 cycles, the TFC-146-02-L-D-A-K-TR provides sufficient contact reliability for 100- to 200-cycle daughtercard applications at a lower BOM cost, making it the preferred choice when budget constraints are a primary design driver.
