What are the key features of TFC-134-02-L-D-A?
- 15 micro-inch gold mating contact finish ensures low contact resistance and long-term corrosion protection in demanding environments
- 68-position dual-row layout at 0.050-inch (1.27 mm) pitch achieves high signal density in a 1.825-inch body length
- Phosphor bronze contacts provide superior spring retention force for reliable repeated mating cycles versus brass alternatives
What is TFC-134-02-L-D-A used for?
The TFC-134-02-L-D-A serves high-density board-to-board mezzanine connections in networking equipment, industrial computers, and data acquisition systems where 68 signals must traverse a compact parallel interface. Its 0.050-inch pitch and 1.825-inch body length allow designers to consolidate large signal buses onto a single connector footprint, reducing PCB routing congestion. Gold mating contacts paired with matte tin terminations balance contact reliability with cost-effective PCB soldering compatibility.

Frequently Asked Questions
What contact finish is used on the mating surfaces of the TFC-134-02-L-D-A, and how does it affect connector longevity?
The TFC-134-02-L-D-A uses 15 micro-inch gold plating on its mating contact surfaces, which provides superior corrosion resistance and maintains low contact resistance below 20 milliohms over hundreds of mating cycles. Gold finish is preferred over tin for high-cycle applications because it does not form an oxide layer that increases resistance under low-normal-force contact conditions typical of fine-pitch connectors.
How does the 0.050-inch pitch of TFC-134-02-L-D-A benefit signal routing on high-density PCBs compared to 0.100-inch alternatives?
At 0.050-inch (1.27 mm) pitch, the TFC-134-02-L-D-A places 68 contacts within a 1.825-inch body length, whereas a 0.100-inch pitch connector for the same pin count would require approximately 3.65 inches. This halved length reduces PCB routing congestion and allows the connector to fit on board edges where available space is under 50 mm, a common constraint in 1U rack-mount server and switch designs.
For a data acquisition system with 64 analog channels, why is TFC-134-02-L-D-A a practical mezzanine interconnect choice?
The 68-position dual-row layout of TFC-134-02-L-D-A provides 64 signal pins plus 4 additional pins available for power or ground returns, matching a typical 64-channel analog I/O requirement without needing a second connector. At 0.050-inch pitch, all 68 contacts occupy a footprint of approximately 46 mm by 6 mm, keeping the mezzanine board stackup compact enough for 2U instrument chassis where vertical module spacing is limited to 88 mm.
When would a design engineer choose TFC-134-02-L-D-A over a higher-cost shielded fine-pitch connector for a backplane interface?
TFC-134-02-L-D-A is the right choice when signal frequencies are below 1 GHz and crosstalk budgets above 3% are acceptable, since the open-pin-field geometry without shielding adequately serves parallel digital buses at those speeds. The cost saving over shielded alternatives can exceed 40% per connector pair, which is significant for backplanes carrying 10 or more connectors that together represent a major portion of interconnect bill-of-materials cost.
