What are the key features of STMM-113-02-F-D-SM-K-TR?

  • Tin-over-nickel contact finish provides reliable solderability and corrosion resistance for long-term board-to-cable mating at 2.00 mm pitch
  • Dual-row female shrouded configuration with 113 positions delivers 226 contact points in a compact 1.257 inch body length
  • Surface-mount footprint supports pick-and-place reflow soldering at peak temperatures up to 260°C for high-volume automated assembly
  • 8.4-year estimated time on market ensures long-term availability for designs with extended production lifecycles

What is STMM-113-02-F-D-SM-K-TR used for?

STMM-113-02-F-D-SM-K-TR is optimized for high-density cable-to-board interconnects in server backplane modules, industrial automation panels, and data acquisition systems where 113 dual-row positions must be accommodated within a 1.257 inch board span. The female shrouded housing mates with SAMTEC male cable assemblies to enable secure, polarized plug-and-unplug connections without risk of pin damage. The surface-mount termination style integrates seamlessly into high-volume SMT production lines.

Frequently Asked Questions

What are the physical dimensions of STMM-113-02-F-D-SM-K-TR and how do they help in layout planning?

The STMM-113-02-F-D-SM-K-TR measures 1.257 inches in body length, 0.237 inches in breadth, and 0.240 inches in depth, with 113 dual-row positions at a 2.00 mm pitch. These dimensions allow PCB designers to allocate a precise board zone of approximately 32 mm × 6 mm for the connector footprint, which is essential when planning trace routing around the connector in dense multi-layer boards with fine pitch BGA components nearby.

How does the tin-over-nickel contact finish on STMM-113-02-F-D-SM-K-TR affect connector reliability?

The tin (Sn) finish with a nickel (Ni) barrier on STMM-113-02-F-D-SM-K-TR's contacts provides a solderable surface with low insertion force while the nickel layer acts as a diffusion barrier to prevent tin from migrating into the base metal. This finish maintains reliable contact resistance below 30 milliohms per contact over typical service lives of 30 to 50 mating cycles, which is adequate for board-to-cable connectors serviced during maintenance intervals in industrial equipment.

For which high-channel-count signal routing scenarios is STMM-113-02-F-D-SM-K-TR preferred over a backplane press-fit connector?

STMM-113-02-F-D-SM-K-TR is preferred over press-fit backplane connectors when the PCB is a single or double-layer flex or rigid-flex board that cannot sustain the 50 N to 100 N insertion force required for press-fit contacts across 113 positions. The surface-mount reflow process distributes solder joint stress evenly, and the 2.00 mm pitch supports current ratings of approximately 1 A per contact, which is sufficient for mixed signal and low-power digital buses in rack-mounted industrial control cards.

How should procurement teams account for STMM-113-02-F-D-SM-K-TR's 8.4-year product lifetime in BOM planning?

With an 8.4-year estimated time on market, STMM-113-02-F-D-SM-K-TR is expected to remain in production well into the early 2030s, making it suitable for industrial designs with 5-year or 7-year production commitments without immediate concern for product obsolescence. Procurement teams should still perform an annual lifecycle review and set an alert at the 5-year mark to evaluate whether SAMTEC has issued a product change notice or last-time-buy window, maintaining at least a 6-month safety stock at peak production volumes.
