What are the key features of TFC-146-02-L-D-A?
- 92-position dual-row layout at 0.050 inch (1.27 mm) pitch delivers one of the highest available pin counts in the Tiger Eye terminal strip series
- Tiger Eye cost-effective design reduces per-position connector cost in commercial-grade high-density board interconnect applications
- Gold mating finish on phosphor bronze contacts ensures consistent low-resistance electrical connections across all 92 positions
- Compact 1.27 mm pitch design enables a high pin count in a small PCB footprint, supporting complex signal bus and power distribution routing
What is TFC-146-02-L-D-A used for?
The TFC-146-02-L-D-A is designed for very high pin count board connector applications in telecommunications line cards, data acquisition backplanes, and large FPGA or DSP development boards. With 92 positions at 0.050 inch pitch, it enables routing of complex multi-bit data buses, analog channels, and power rails through a single connector in densely populated PCB assemblies. The Tiger Eye cost-effective design makes it an economical solution for high-volume commercial production runs requiring maximum connectivity density at minimum cost per connection.

Frequently Asked Questions
How many positions does the TFC-146-02-L-D-A provide and how are they organized across the connector body?
The TFC-146-02-L-D-A provides 92 positions organized in a dual-row configuration with 46 pins per row at 0.050 inch (1.27 mm) pitch. This layout supports simultaneous routing of up to 92 independent signal or power connections through a single compact connector in high-density PCB designs.
Which high-complexity PCB designs benefit most from the 92-position density of the TFC-146-02-L-D-A?
Large FPGA development boards, telecommunications line cards, and industrial backplane systems benefit most from the TFC-146-02-L-D-A's 92-position capacity. These designs often require routing 64-bit or wider data buses together with control signals and multiple power rails, all of which can be consolidated through the single 92-pin dual-row connector at 1.27 mm pitch.
What contact finish specification does the TFC-146-02-L-D-A use and how does this ensure signal integrity?
The TFC-146-02-L-D-A uses gold plating on phosphor bronze mating contacts. Gold provides less than 10 milliohm contact resistance and excellent resistance to oxidation, ensuring consistent signal integrity across all 92 positions over the service life of the connector in typical commercial operating environments.
How does the Tiger Eye design in TFC-146-02-L-D-A compare to premium alternatives for applications requiring only occasional mating?
For applications where the connector is mated only during initial assembly or infrequent field service — typically fewer than 30 cycles — the Tiger Eye design in TFC-146-02-L-D-A provides equivalent functional reliability at lower cost compared to premium connectors rated for 100 or more cycles. This cost advantage is amplified at 92 positions, making it particularly economical for high-volume production of fixed-installation electronic systems.
