What are the key features of TFC-139-02-L-D-A?
- 78-position dual-row configuration with 0.050" (1.27 mm) pitch enabling very high-density signal routing in a single compact connector body
- Tiger Eye cost-effective contact technology providing reliable mating performance at reduced cost compared to premium contact finishes
- Dual-row through-hole terminal strip format compatible with standard wave or hand soldering processes for flexible PCB assembly
What is TFC-139-02-L-D-A used for?
The TFC-139-02-L-D-A is designed for high pin-count board-to-board interfaces in server backplanes, telecommunications line cards, and industrial automation controllers where 78 signals must be routed at 0.050" pitch. The Tiger Eye contact design balances performance and procurement cost, making it a practical choice for medium-to-high-volume production. It is also used in FPGA prototyping boards and data acquisition systems that require a large number of parallel signal connections in a compact connector footprint.

Frequently Asked Questions
How many signals can the TFC-139-02-L-D-A carry and at what pitch?
The TFC-139-02-L-D-A supports 78 total positions arranged in a dual-row layout at 0.050" (1.27 mm) pitch. This high pin count in a single connector body allows engineers to consolidate data bus, control, and power signals, reducing the number of connector bodies needed on a PCB compared to using multiple lower-position-count strips.
What PCB assembly methods are compatible with the TFC-139-02-L-D-A terminal strip?
The TFC-139-02-L-D-A uses through-hole termination compatible with both wave soldering and hand soldering. Its 78-position dual-row footprint at 0.050" pitch can be placed with automated insertion equipment for high-volume production, or by hand for prototype runs, giving production engineers flexibility in their assembly process without requiring special equipment.
In what cost-sensitive scenarios would a designer select TFC-139-02-L-D-A over a premium series connector?
When a design requires 78-position dual-row connectivity at 0.050" pitch for commercial-grade equipment with moderate mating cycle requirements, the TFC-139-02-L-D-A Tiger Eye series reduces per-unit connector cost without sacrificing basic reliability. Applications like server backplanes, industrial panel controllers, or telecom interface cards that need high pin counts but do not require extended-life gold plating benefit most from this cost-effective selection.
