Frequently Asked Questions
How many positions and rows does the SFM-121-T2-F-D-A-K-TR connector provide, and what pitch does it use?
The SFM-121-T2-F-D-A-K-TR features 42 positions arranged in a dual-row configuration on a 0.050-inch (1.27mm) pitch. This compact footprint allows 21 contacts per row, making it suitable for high-density board-to-board signal interfaces in embedded systems and communication modules.
In which high-density board interconnection scenarios does the SFM-121-T2-F-D-A-K-TR outperform 2.54mm pitch alternatives?
When PCB real estate is constrained, the SFM-121-T2-F-D-A-K-TR at 1.27mm pitch occupies roughly half the board area of a comparable 2.54mm pitch connector for 42 positions. This makes it preferable in compact FPGA daughter card, DIMM-style module, and mezzanine board designs where space savings of several square centimeters per connector matter.
Is the SFM-121-T2-F-D-A-K-TR supplied in tape-and-reel format for SMT assembly lines?
Yes, the -TR suffix indicates the SFM-121-T2-F-D-A-K-TR is packaged in tape-and-reel format, supporting automated pick-and-place assembly for surface-mount production. The reel packaging is compatible with standard SMT reflow processes, enabling high-volume manufacturing of boards requiring 42-pin dual-row 1.27mm pitch socket connectors.
What mating connector series is compatible with the SFM-121-T2-F-D-A-K-TR socket strip?
The SFM-121-T2-F-D-A-K-TR mates with SAMTEC's TSM or TFM series headers using the same 0.050-inch (1.27mm) pitch dual-row layout. These mating headers provide a secure mechanical and electrical interface supporting signal integrity at frequencies up to several hundred MHz in high-speed digital bus applications.
