What are the key features of SFM-131-02-STL-D-A-P-TR?
- 62 positions in dual-row 0.050" (1.27 mm) pitch for high-density surface mount board interconnection
- Stainless steel tail (STL) finish provides corrosion resistance suited for demanding environments
- Tape-and-reel (-TR) packaging enables high-throughput automated pick-and-place SMT assembly
- 1 A per contact rating with high-reliability socket construction for extended service life
What is SFM-131-02-STL-D-A-P-TR used for?
The SFM-131-02-STL-D-A-P-TR is designed for high-density board-to-board and mezzanine card interconnects in defense electronics, industrial computing, and advanced instrumentation where fine-pitch 0.050 inch socket strips with 62 contacts are required. Its stainless steel tail finish combined with the high-reliability socket body makes it appropriate for assemblies exposed to vibration, thermal cycling, or corrosive environments. Tape-and-reel delivery supports efficient automated production loading, reducing per-unit assembly cost in volume builds.

Frequently Asked Questions
How many positions does the SFM-131-02-STL-D-A-P-TR provide, and how are they distributed across rows?
The SFM-131-02-STL-D-A-P-TR provides 62 contact positions arranged in 2 rows of 31, on a 0.050 inch (1.27 mm) pitch. This dual-row, fine-pitch layout supports high-density bus routing on compact PCBs, making it particularly valuable in mezzanine card and daughter-board interconnect designs where board real estate is constrained.
Why specify the stainless steel tail (STL) finish on the SFM-131-02-STL-D-A-P-TR instead of a gold-plated finish?
The stainless steel tail (STL) finish offers superior corrosion and oxidation resistance compared to tin, making it a good choice for assemblies operated in humid or mildly corrosive environments. Although gold plating provides lower contact resistance (typically below 20 milliohms), the STL finish reduces material cost while still maintaining reliable PCB solder joint integrity at standard reflow peak temperatures of 245 °C to 260 °C.
What current rating applies per contact, and how does this affect power rail allocation on the SFM-131-02-STL-D-A-P-TR?
Each of the 62 contacts is rated at 1 A, which is standard for SAMTEC's 0.050 inch pitch SFM series. Designers typically group multiple contacts in parallel for power rails — for example, using 4 contacts in parallel yields a 4 A capacity for a 3.3 V supply bus — while allocating the remaining positions to digital signal lines, achieving a flexible mixed signal-and-power distribution scheme within a single 62-position connector.
Is the SFM-131-02-STL-D-A-P-TR compatible with automated SMT lines, and in what format is it supplied?
Yes, the SFM-131-02-STL-D-A-P-TR is supplied on tape-and-reel (-TR), making it fully compatible with automated pick-and-place machines operating at standard SMT assembly throughputs. The surface mount termination style is compatible with lead-free SAC305 reflow solder profiles with a peak temperature of up to 260 °C, and tape-and-reel packaging ensures consistent part orientation for accurate placement across all 62 positions.
