Frequently Asked Questions
What is the pitch and total position count of the SFM-131-L2-SM-D-A-K socket strip?
The SFM-131-L2-SM-D-A-K provides 62 positions in a dual-row configuration with 31 contacts per row, all spaced at 0.050" (1.27 mm) pitch. This compact layout allows routing of 62 signal or power lines through a single SMT connector with a minimal PCB footprint.
How does the L2 lead style on the SFM-131-L2-SM-D-A-K improve PCB assembly quality?
The L2 lead style provides extended surface mount leads that extend beyond the connector body perimeter, allowing automated optical inspection (AOI) systems and human inspectors to visually verify solder fillet formation on all 62-position terminations after standard 260°C reflow soldering without removing the connector.
What contact plating specification makes the SFM-131-L2-SM-D-A-K suitable for high-cycle mating applications?
SAMTEC specifies gold-over-nickel plating on the SFM-131-L2-SM-D-A-K mating contacts—typically 30 µin (0.76 µm) gold minimum—delivering contact resistance below 20 mΩ and sustained performance across hundreds to thousands of mating cycles without significant oxidation or wear degradation.
How does SFM-131 differ from SFM-132 when selecting a 0.050" dual-row socket for a specific position count?
The SFM-131-L2-SM-D-A-K provides 62 positions versus 64 positions on the SFM-132 variant, both using the identical 0.050" (1.27 mm) pitch dual-row SMT footprint. Designers needing exactly 62 contacts to match a specific mating header choose SFM-131 to avoid unused positions and unmatched footprint length.
Which procurement channel offers the SFM-131-L2-SM-D-A-K with the shortest lead time?
The SFM-131-L2-SM-D-A-K is stocked by major authorized SAMTEC distributors including Digi-Key, Mouser, and Arrow, typically offering same-day shipping for quantities up to several hundred pieces. SAMTEC's factory lead time for custom or larger order quantities is generally 1–3 weeks depending on production schedules.
