Frequently Asked Questions
What pitch and row configuration does the SFM-121-02-ZZ-D-A-K-TR use?
The SFM-121-02-ZZ-D-A-K-TR features a 0.050" (1.27 mm) pitch dual-row socket strip with 42 total positions (21 per row), enabling high-density board-to-board signal routing in space-constrained PCB designs.
Which assembly processes are compatible with the SFM-121-02-ZZ-D-A-K-TR connector?
This connector uses surface-mount termination compatible with standard reflow soldering processes. The TR (tape-and-reel) packaging allows automated pick-and-place assembly, supporting high-volume production with 0.050" pitch placement accuracy.
In what types of electronic systems is the SFM-121-02-ZZ-D-A-K-TR commonly used?
The SFM-121-02-ZZ-D-A-K-TR is used in telecommunications equipment, industrial control modules, and test-and-measurement instrumentation where 42-position dual-row SMT connectors with 1.27 mm pitch are required for reliable high-density board-to-board interconnects.
How does the dual-row design of the SFM-121-02-ZZ-D-A-K-TR compare to single-row alternatives?
The dual-row layout packs 42 contacts into approximately half the board length required by a single-row equivalent, saving significant PCB real estate. Each row carries 21 pins at 0.050" (1.27 mm) pitch, making it a compact option for dense signal routing.
