Frequently Asked Questions
Does TFM-121-02-STL-D-RA match a layout already built around 1.27 mm contact spacing?
TFM-121-02-STL-D-RA uses 1.27 mm contact spacing, so the PCB land pattern and mating component must preserve that pitch across every position during layout verification.
What makes this high-reliability terminal strip appropriate for repeatable production board mating?
This high-reliability terminal strip uses a 1.27 mm interface suited to compact board interconnects; engineers should also confirm stack height, termination, polarization, and rated mating cycles.
Before substituting TFM-121-02-STL-D-RA, which mechanical details need supplier confirmation?
Procurement should match the exact 1.27 mm pitch, row arrangement, termination style, polarization, contact finish, and packaging code against the released manufacturer drawing.
