Frequently Asked Questions
What contact material and plating does the STMM-115-02-T-D-SM use, and why does it matter?
The STMM-115-02-T-D-SM uses phosphor bronze contacts with matte tin over 50 µin nickel underplate on the mating surfaces and matte tin with nickel barrier on the PCB termination. Phosphor bronze provides superior spring-back resilience, maintaining consistent contact force across 30 positions even after multiple mating cycles and thermal cycling.
How many positions does the STMM-115-02-T-D-SM provide, and in what row configuration?
The STMM-115-02-T-D-SM provides 30 positions arranged in 2 rows of 15 contacts each, with a rectangular contact pattern. This dual-row male connector is designed to mate with compatible SAMTEC female socket strips in a board stacking configuration, supporting 30 simultaneous signal or power connections between mated PCBs.
What is the body size of the STMM-115-02-T-D-SM and how does it compare to larger dual-row stacking connectors?
The STMM-115-02-T-D-SM body measures 0.257 inch wide by 0.19 inch deep, making it significantly more compact than 50- or 80-position board stacking connectors. This compact 30-position footprint is ideal for space-constrained mezzanine PCBs in portable instruments, handheld devices, and small embedded modules.
Is the STMM-115-02-T-D-SM compatible with lead-free reflow soldering processes?
Yes, the STMM-115-02-T-D-SM is RoHS compliant and uses matte tin with nickel barrier termination, which is fully compatible with lead-free solder alloys and standard SAC305 reflow profiles with peak temperatures up to 260°C, meeting global environmental compliance requirements for consumer, industrial, and telecommunications products.
What is the typical factory lead time for the STMM-115-02-T-D-SM and how can procurement be expedited?
SAMTEC quotes a 3-week factory lead time for the STMM-115-02-T-D-SM. Buyers needing faster delivery can check authorized distributors such as Digi-Key and Mouser, which typically maintain stock of SAMTEC's STMM series and can ship same-day for small to medium quantities of up to several hundred pieces.
