Frequently Asked Questions
What are the key electrical and mechanical specifications of the SFM-123-L2-F-D-A-K-TR?
The SFM-123-L2-F-D-A-K-TR features 46 positions in a dual-row arrangement at 0.050" (1.27 mm) pitch, with gold-plated contacts rated for 1 A current per pin, and is designed for surface mount PCB assembly with standard reflow soldering at up to 260°C peak temperature.
For which embedded computing or signal processing boards is the SFM-123-L2-F-D-A-K-TR a good mezzanine connector choice?
This connector suits FPGA mezzanine cards, DSP daughter boards, and COM Express modules where 46 pins at 1.27 mm pitch provide adequate signal count in a compact footprint. The dual-row configuration delivers 23 contacts per row, supporting high-speed differential pairs and power rails simultaneously in a space-efficient PCB layout.
How does the -L2 variant designation affect the SFM-123-L2-F-D-A-K-TR connector stack height?
The -L2 suffix specifies the mating height or lead style of the connector, affecting the board-to-board stack height in mezzanine assemblies. Selecting the correct L-variant ensures the mated pair achieves the target standoff distance, typically ranging from 2 mm to 10 mm depending on the chosen option, which is critical for component clearance in compact multi-board assemblies.
Is the SFM-123-L2-F-D-A-K-TR a suitable drop-in alternative to other 46-pin 1.27 mm pitch dual-row SMT connectors?
The SFM-123-L2-F-D-A-K-TR mates with SAMTEC's corresponding header series and shares the industry-standard 1.27 mm (0.050") pitch grid used by many dual-row SMT connectors. Pin-count compatibility with 46-position dual-row footprints from other manufacturers should be verified against pad layout and mating height before substitution.
