Frequently Asked Questions
How many total contact positions does the TFC-129-02-F-D-A-K provide and how are they arranged?
The TFC-129-02-F-D-A-K provides 258 total positions arranged in 2 rows of 129 contacts each, with a 0.050-inch (1.27 mm) pitch between adjacent pins. This dual-row configuration allows designers to carry a very large number of signals through a single connector, reducing board-space requirements compared to using multiple lower-count connectors.
What soldering process is compatible with the TFC-129-02-F-D-A-K termination style?
The F-suffix denotes straight-pin through-hole termination, which is compatible with both wave soldering and selective hand-soldering processes. Through-hole pins extend through the PCB and are soldered on the secondary side, providing strong mechanical retention and reliable electrical contact. This style is commonly preferred in industrial and mil-aero designs where vibration resistance is important, and the connector can withstand solder temperatures up to 260°C during the wave-solder process.
In which system-level applications is the TFC-129-02-F-D-A-K most commonly used?
The TFC-129-02-F-D-A-K is most commonly deployed in high-density backplane interconnect systems, FPGA mezzanine cards, and parallel data bus interfaces where 258 simultaneous signal channels are needed. It also fits test and measurement instrumentation, VME or cPCI card-edge daughter cards, and data acquisition front-ends operating at signal frequencies up to 100 MHz or higher, where the Tiger Eye contact technology ensures consistent performance across the full contact array.
How does the SAMTEC TFC series compare to the SFM series for high-density applications?
Both the TFC and SFM series operate at 0.050-inch pitch, but the TFC series uses Tiger Eye contacts for enhanced mating reliability, while the SFM series focuses on surface-mount receptacle pairing. The TFC-129-02-F-D-A-K with 258 through-hole pins offers stronger mechanical attachment to the PCB versus surface-mount alternatives, making it preferable in applications subject to mechanical stress or where more than 500 mating cycles are expected. Choose TFC when robustness and pin count above 200 positions are both required.
