Frequently Asked Questions
How many positions and what pitch does the SFM-123-T2-F-D-A-K provide?
The SFM-123-T2-F-D-A-K offers 46 total positions arranged in a dual-row configuration at 0.050" (1.27 mm) pitch, delivering high signal density in a compact SMT footprint suitable for space-constrained FPGA and processor mezzanine board designs.
How many mating cycles can the SFM-123-T2-F-D-A-K withstand in a high-reliability application?
SAMTEC high-reliability socket strips in the SFM series are rated for a minimum of 200 mating cycles with gold-plated contacts, making them suitable for defense, aerospace, and medical equipment where repeated board swapping occurs and contact integrity must be maintained over the product's lifetime.
For a compact FPGA mezzanine design, how does the 0.050" pitch compare to standard 0.100" connectors?
The 0.050" (1.27 mm) pitch of the SFM-123-T2-F-D-A-K provides twice the contact density compared to standard 0.100" (2.54 mm) pitch connectors, allowing 46 signals in roughly half the PCB area. This makes it the preferred choice for high pin-count FPGA daughter cards and compact embedded computing modules where board space is at a premium.
What SAMTEC plug series mates with the SFM-123-T2-F-D-A-K?
The SFM-123-T2-F-D-A-K is designed to mate with SAMTEC's SFS and SFM series surface mount plug strips sharing the same 0.050" (1.27 mm) pitch and 46-position dual-row layout, supporting board stack heights from 4 mm to 20 mm depending on the selected mating connector option.
