Frequently Asked Questions
How many contact positions does the TFM-147-21-F-D provide and how are they laid out?
The TFM-147-21-F-D provides 94 total contact positions arranged in a dual-row configuration at 0.050" (1.27 mm) pitch, giving 47 positions per row. This dual-row layout at 0.050" pitch enables very high signal density while keeping the connector's overall board footprint small, which is critical on dense PCBs with limited real estate.
For a ruggedized industrial PCB, why choose TFM-147-21-F-D's through-hole termination over a surface-mount alternative?
Through-hole termination on the TFM-147-21-F-D anchors each pin mechanically in the PCB, providing pull-out force resistance of several kilograms per contact — significantly higher than typical surface-mount solder joints. This makes it preferable in industrial, aerospace, or automotive applications where the assembly may experience vibration levels above 5 G or repeated plug-and-unplug cycles exceeding 500 times.
What is the Tiger Eye contact technology in the TFM-147-21-F-D and how does it differ from standard stamped contacts?
Tiger Eye contacts in the TFM-147-21-F-D use a proprietary Samtec stamped-and-formed geometry that grips the mating pin with multiple contact points, delivering lower contact resistance — typically below 20 mΩ — compared to single-point stamped contacts. The gold plating of up to 30 µin further reduces oxidation-related resistance drift over time and through environmental cycling.
When would a designer choose TFM-147-21-F-D over a Samtec SFM series connector for the same application?
A designer would choose TFM-147-21-F-D when the PCB layout requires through-hole soldering — for example, when board thickness exceeds 1.6 mm or when wave-soldering is the production process — whereas the SFM series uses surface-mount termination compatible with reflow ovens. The TFM series also supports higher mechanical retention per contact, making it the better choice for connectors subjected to forces above 2 N per pin during cable mate/unmate operations.
