What are the key features of TFC-137-02-F-D-A?
- 74-position dual-row 0.050" (1.27 mm) pitch layout delivers very high signal density per unit PCB length
- Tiger Eye contact design provides low insertion force with secure retention across hundreds of mating cycles
- Gold-plated contacts maintain low contact resistance below 20 mΩ and resist corrosion in long-term deployments
- Cost-effective terminal strip format reduces connector BOM cost versus premium high-speed alternatives for non-critical signal interfaces
What is TFC-137-02-F-D-A used for?
The TFC-137-02-F-D-A is engineered for high-density signal interconnection in FPGA development boards, industrial backplanes, and multi-channel data acquisition systems where routing 74 signals through a single compact connector is essential. Its 0.050" pitch dual-row layout consolidates a large I/O count into a smaller PCB area than 0.100" alternatives, enabling more compact embedded module designs. The connector is also found in test and measurement daughter-card interfaces requiring repeatable mechanical mating.

Frequently Asked Questions
How many signal positions does TFC-137-02-F-D-A provide and how compact is the connector body?
The TFC-137-02-F-D-A provides 74 positions in a 2-row layout on a 0.050" (1.27 mm) pitch. The connector body length is approximately 37 x 0.050" = 1.85" (47 mm), packing 74 signal connections into under 2 inches of PCB length. This density is critical in FPGA expansion cards and multi-channel data acquisition boards where physical board size is strictly constrained.
How does TFC-137-02-F-D-A enable cost savings compared to high-speed connectors for low-frequency signals?
For digital interfaces operating below 200 MHz — such as GPIO buses, parallel data ports, or control signal harnesses — the TFC-137-02-F-D-A provides 74-position dual-row connectivity at a fraction of the cost of high-speed differential pair connectors like SEARAY or SEARAY-HS. Engineers can allocate saved BOM budget to other critical components when signal integrity analysis confirms that 0.050" pitch stripline connections are adequate for the design's data rate and 74-signal count requirements.
In which industrial applications is TFC-137-02-F-D-A most commonly used for high-pin-count signal routing?
Industrial motion control systems with 74 or more I/O channels, programmable logic controller (PLC) expansion modules, and multi-axis servo drive backplanes commonly use 74-position 0.050" pitch connectors like TFC-137-02-F-D-A. These applications require reliable operation at temperatures from -40°C to +85°C and expect the connector to sustain hundreds of board insertion/removal cycles during commissioning and maintenance without degraded contact resistance.
What mating connector family is compatible with TFC-137-02-F-D-A and how should pin 1 orientation be verified?
The TFC-137-02-F-D-A mates with SAMTEC TFM-series receptacles and compatible 0.050" dual-row pin headers. Pin 1 is typically indicated by a chamfer on one corner of the connector housing and a square pad on the PCB footprint. Verifying pin 1 orientation before first mating is critical on 74-position connectors because a misaligned insertion can damage all 74 contacts simultaneously, and the connector body is approximately 1.85" long with no keying features in the basic TFC series.
