Frequently Asked Questions
What contact pitch and pin count does the STMM-108-02-L-D-SM board stacking connector provide?
The STMM-108-02-L-D-SM is a 16-position connector arranged in a dual-row, 8-per-row configuration with a 2.00 mm center-to-center pitch. This layout allows routing 16 signals or a mix of power and signal lines in a board body length of approximately 0.873 inches, making it practical for stacking compact PCB modules in embedded systems.
How does the gold-over-nickel contact finish of the STMM-108-02-L-D-SM affect long-term connector reliability?
The mating contacts are plated with 10 µin of gold over 50 µin of nickel, which provides excellent corrosion resistance and consistently low contact resistance over thousands of mating cycles. Gold prevents oxide layer formation that would increase resistance in humid or contaminated environments, making this finish preferred for high-reliability industrial and instrumentation board-stack assemblies.
What are the procurement lead time and RoHS status of the STMM-108-02-L-D-SM for production planning?
The STMM-108-02-L-D-SM is RoHS compliant and lead-free, which satisfies EU and global environmental regulations for new electronic product designs. Samtec typically stocks this connector family with short lead times, often under 4 weeks, and the SMT termination style is compatible with standard automated pick-and-place and reflow soldering at temperatures up to 260°C per IPC J-STD-020.
