Frequently Asked Questions
What contact arrangement does the SFM-123-02-S-D-K-TR socket strip use?
The SFM-123-02-S-D-K-TR uses a 46-position, dual-row (2x23) arrangement with 0.050" (1.27 mm) pitch. This layout provides high-density surface-mount connectivity, mating with compatible SAMTEC TFM or SFM series pin headers, and is commonly used in compact FPGA daughter card and mezzanine module applications.
How does the SFM-123-02-S-D-K-TR compare to larger 54-position SFM-127 for signal-dense designs?
The SFM-123-02-S-D-K-TR with 46 contacts provides a shorter PCB footprint than the 54-position SFM-127, making it the better choice when board routing constraints or connector spacing rules limit available PCB real estate. Both use 0.050" (1.27 mm) pitch, so PCB layout changes are minimal when switching between the two variants.
Is the SFM-123-02-S-D-K-TR compatible with lead-free PCB assembly processes?
Yes, the SFM-123-02-S-D-K-TR is designed for lead-free SMT reflow soldering compatible with RoHS-compliant processes. Its contact materials and housing are rated for standard lead-free peak reflow temperatures above 250°C, and the tape-and-reel packaging supports automated assembly on modern pick-and-place equipment.
What reliability rating makes the SFM-123-02-S-D-K-TR suitable for demanding interconnect applications?
SAMTEC's SFM series high-reliability socket strips are rated for repeated mating cycles and deliver consistent contact resistance across the life of the connector. The dual-row 46-position design at 1.27 mm pitch is qualified for use in industrial, telecommunications, and defense-grade applications where connection reliability over thousands of cycles is critical.
