Frequently Asked Questions
What is the mating contact finish on STMM-125-02-F-D-SM and why does it matter for board stacking?
The STMM-125-02-F-D-SM uses gold flash over nickel on its mating contacts, which provides excellent corrosion resistance and stable contact resistance across the 50 mating pins. Gold finishes are preferred in board stacking applications because they maintain reliable electrical performance over many insertion cycles, typically rated for 30 or more mate-unmate cycles without significant contact degradation.
How many circuits does STMM-125-02-F-D-SM support and what is its board stacking pitch?
This connector supports 50 circuits arranged in a dual-row (25x2) configuration at a 2.00 mm pitch, making it suitable for high-density board stacking interfaces. The body measures approximately 0.257 inch in breadth and 0.19 inch in depth, enabling compact stacking arrangements between two PCBs while routing substantial numbers of signal and power lines.
What is the factory lead time for STMM-125-02-F-D-SM and is it RoHS compliant?
SAMTEC lists a standard factory lead time of 2 weeks for the STMM-125-02-F-D-SM, and the part carries a RoHS-compliant (Pb-free) designation. The tin-with-nickel-barrier termination finish further confirms lead-free soldering compatibility, making it suitable for environmentally regulated product designs shipped to EU markets under RoHS directives.
