Frequently Asked Questions
What is the contact pitch and row count of the SFM-146-L2-S-D-A-K, and how does this affect routing density on the PCB?
The SFM-146-L2-S-D-A-K uses a 0.050-inch (1.27 mm) pitch in a dual-row layout providing 92 positions total, which is 46 positions per row. This tight pitch supports very high routing density, making it suitable for FPGA mezzanine cards and signal-dense backplane interfaces where board real estate is at a premium.
Which SAMTEC mating plug series is designed to mate with the SFM-146-L2-S-D-A-K for a complete board-to-board stack?
The SFM-146-L2-S-D-A-K mates with the SAMTEC CLM or TSM male strip series designed for the 0.050-inch pitch dual-row SFM socket family. The mated pair provides a reliable 92-pin interconnect rated for repeated mate and unmate cycles, maintaining contact resistance below 20 mΩ per contact in a compact dual-row surface mount stack-up.
Can the SFM-146-L2-S-D-A-K be used in a high-cycle prototype environment, or is it better suited for production board-level assembly?
The SFM series features Tiger Eye contact technology rated for up to 100 mating cycles while maintaining reliable electrical performance. For high-cycle prototype environments requiring hundreds of insertions, engineers may prefer a zero-insertion-force (ZIF) alternative. For production board assembly with fewer than 100 mating cycles, the SFM-146-L2-S-D-A-K surface mount socket is well suited and supports soldering at standard reflow temperatures up to 260°C.
How does SFM-146-L2-S-D-A-K compare in position count to narrower variants like SFM-143 for designs with moderate I/O requirements?
The SFM-146-L2-S-D-A-K provides 92 positions versus the SFM-143 series which offers 86 positions at the same 0.050-inch dual-row pitch. For designs that only need up to 86 I/O lines, the SFM-143 saves approximately 6 mm of PCB length. When 92 signals or power pins are required, the SFM-146 is the correct choice in the SAMTEC SFM socket strip family.
