Frequently Asked Questions
What is the contact pitch of the STMM-125-02-T-D-SM and how does it compare to standard 2.54 mm connectors?
The STMM-125-02-T-D-SM uses a 2.00 mm pitch, which is tighter than the legacy 2.54 mm (0.1 inch) standard. This smaller pitch allows more contacts in the same board footprint, making it a suitable choice for compact industrial and embedded designs where space is at a premium. The 50-pin matte tin over nickel contacts deliver reliable conductivity in this dense layout.
What termination style does the STMM-125-02-T-D-SM use, and which PCB assembly processes support it?
The STMM-125-02-T-D-SM uses a surface mount (SM) termination style, compatible with automated SMT pick-and-place and reflow soldering processes. The contact finish is matte tin over nickel with a nickel barrier, providing a solderable surface for reliable solder joint formation on standard FR4 PCBs at reflow temperatures up to 260°C.
Which board-to-board or cable mate systems are compatible with the STMM-125-02-T-D-SM?
The STMM-125-02-T-D-SM is designed as a cable mate board stacking connector in SAMTEC's STMM series with 2.00 mm pitch. Compatible mating connectors in SAMTEC's ecosystem include dual-row female receptacle strips at the same 2.00 mm pitch, enabling reliable 50-pin board-to-board stacking connections in test equipment and industrial control systems.
How long is the typical lead time for the STMM-125-02-T-D-SM and is it RoHS compliant?
The STMM-125-02-T-D-SM has a factory lead time of approximately 3 weeks when not available from distributor stock. It is RoHS compliant (Pb-free code: Yes), with tin-over-nickel contact plating that meets halogen-free and environmental directive requirements for industrial and commercial electronics sold in regulated markets.
