Key Features
- 46-position dual-row layout at 0.050" (1.27mm) pitch enables very high signal density in a compact board footprint
- Tiger Eye contact design with gold mating finish provides reliable low-resistance electrical connections across thousands of mating cycles
- Cost-effective terminal strip format compatible with standard 0.050" pitch SAMTEC mating connector families
Applications
The TFC-123-02-L-D-A is suited for high pin-count board-to-board interconnects in FPGAs, processor modules, DSP daughter cards, and high-speed data acquisition systems requiring 46 signals in a tight footprint. Its 0.050" pitch dual-row configuration supports up to 23 differential pairs, ideal for LVDS, SERDES, or DDR memory interfaces. The Tiger Eye contact geometry ensures consistent impedance and signal integrity on high-frequency signals up to several gigahertz when mated properly.

Frequently Asked Questions
What signal capacity does the 46-position TFC-123-02-L-D-A provide for FPGA and DSP daughter card designs?
The TFC-123-02-L-D-A provides 46 contacts in a dual-row 0.050" pitch strip, accommodating 46 single-ended signals or up to 23 differential pairs. This density supports DDR memory buses, LVDS video interfaces, and multi-channel ADC data paths on FPGA daughter cards and DSP modules, where a single connector replaces multiple lower-density headers to reduce assembly complexity and PCB area.
How does the 0.050" pitch of the TFC-123-02-L-D-A reduce PCB footprint compared to a 0.100" pitch alternative?
At 0.050" (1.27mm) pitch, the TFC-123-02-L-D-A packs 46 positions into a body approximately 1.15 inches long, while the equivalent 0.100" pitch connector would require roughly 2.3 inches for the same pin count. This 50% reduction in connector length directly shrinks the PCB routing zone and is critical for compact FPGA evaluation boards, embedded computing modules, and RF signal processing assemblies.
What procurement advantage does the Tiger Eye cost-effective design offer versus premium SAMTEC connector lines?
The Tiger Eye cost-effective terminal strip series is engineered to deliver gold-finish contact reliability at a lower unit price compared to SAMTEC's high-cycle or zero-insertion-force premium lines, making the TFC-123-02-L-D-A economical for production volumes of 500 units or more. It retains gold plating for corrosion resistance and low contact resistance below 20 mΩ while reducing material cost in applications where mating cycles remain under approximately 100 insertions per connector lifetime.
