Frequently Asked Questions
How many positions does the TFC-121-02-F-D provide and what pitch spacing does it use?
The TFC-121-02-F-D is a 42-position dual-row terminal strip with 0.050 inch (1.27 mm) pitch, providing 21 positions per row. This high-density configuration allows routing of 42 signals through a connector footprint of approximately 26.7 mm in length, making it effective for space-constrained data acquisition and telecommunications board designs.
What distinguishes the Tiger Eye contact design of TFC-121-02-F-D from standard terminal strip contacts?
The Tiger Eye contact design in TFC-121-02-F-D offers controlled low insertion force while maintaining retention forces above 100 grams per contact, reducing the risk of PCB pad damage during assembly. This geometry also provides more consistent contact resistance below 20 milliohms compared to standard bifurcated contacts, which is critical for high-signal-count 42-position connectors.
When should a designer choose TFC-121-02-F-D over a similar SAMTEC connector with a larger pitch?
Designers should choose TFC-121-02-F-D when board area is constrained and 42 signals must be accommodated at 0.050 inch pitch rather than 0.100 inch pitch, which would require nearly twice the board length. Applications in rack-mount telecom blades, compact data loggers, and dense FPGA daughterboards where less than 30 mm connector width is needed benefit most from this 1.27 mm pitch strip.
