Frequently Asked Questions
How many positions does STMM-125-02-T-D-SM-K-TR provide, and how does the dual-row layout help routing?
The STMM-125-02-T-D-SM-K-TR features 125 positions arranged in 2 rows at a 2.00 mm pitch, giving a total of 250 contact points in a compact shrouded footprint. The dual-row configuration reduces the connector's length by roughly half compared to a single-row design at the same contact count, freeing board space for other components in dense 19-inch rack or backplane layouts.
Which cable assembly families from SAMTEC mate with STMM-125-02-T-D-SM-K-TR?
SAMTEC lists multiple compatible cable assembly mates for the STMM series, including FFSD and IDSS ribbon cable connectors with 2.00 mm pitch that match the dual-row 2 mm male contacts. These mating assemblies are available in various lengths and wire gauges rated for signal currents up to 1 A per contact, enabling flexible harness routing in industrial and telecommunications enclosures.
How does the surface-mount termination of STMM-125-02-T-D-SM-K-TR affect PCB assembly and reflow soldering?
The SM (surface-mount) termination style on STMM-125-02-T-D-SM-K-TR allows the connector to be placed by automated pick-and-place machines and soldered in a standard lead-free reflow oven at peak temperatures around 260°C. This eliminates the need for through-hole drilling on 125 positions per connector, reducing board fabrication cost and enabling use on thin PCBs where drill depth is constrained below 1.6 mm.
What does the tape-and-reel packaging (TR suffix) of STMM-125-02-T-D-SM-K-TR mean for procurement lead times?
The TR suffix indicates the STMM-125-02-T-D-SM-K-TR is packaged in tape-and-reel format, typically in reels of 100 to 500 pieces depending on connector size, supporting continuous automated feeder loading. This packaging is preferred for production runs of 1000 or more units where manual tray handling would slow throughput, and SAMTEC's 8.4-year estimated time on market supports long-term procurement planning without obsolescence risk.
