What are the key features of SFM-128-02-SM-D?
- 56-position dual-row surface-mount layout at 1.27 mm pitch provides 56 independent signal channels in a compact SMT footprint
- High-reliability socket strip construction maintains low contact resistance over extended mating cycles in demanding applications
- Surface-mount termination style enables reflow soldering compatibility and eliminates through-hole drilling, reducing PCB layer count
- Dual-row configuration doubles pin density per unit length compared to single-row strips at the same 1.27 mm pitch
What is SFM-128-02-SM-D used for?
The SFM-128-02-SM-D is suited for high-density board-to-board mezzanine interconnects in server blades, FPGA compute modules, and high-speed data acquisition systems. With 56 positions at 1.27 mm pitch, it accommodates mixed signal and power routing in a single compact connector footprint. The surface-mount design allows co-planar reflow soldering alongside other SMT components, simplifying PCB manufacturing.

Frequently Asked Questions
How many pins and what pitch does the SFM-128-02-SM-D provide in its dual-row layout?
The SFM-128-02-SM-D provides 56 positions in a dual-row configuration at 1.27 mm (0.050 inch) pitch, which places 28 pins per row in a strip measuring approximately 34.3 mm in length. This fine pitch enables high-density signal routing for FPGA mezzanine cards and data acquisition boards where space is limited but channel count is critical.
Is the SFM-128-02-SM-D compatible with standard SMT reflow soldering and what mounting style does it use?
Yes, the SFM-128-02-SM-D uses surface-mount (SM) termination style, making it fully compatible with standard SMT reflow soldering profiles up to 260°C peak. This eliminates the need for through-hole drilling and wave soldering, allowing the connector to be placed by pick-and-place equipment alongside 0402 and 0201 passive components in a single reflow pass.
What high-reliability design features make the SFM-128-02-SM-D suitable for harsh environment board interconnects?
The SFM-128-02-SM-D uses Samtec's high-reliability socket strip construction with gold-plated mating contacts that maintain contact resistance below 20 mΩ across hundreds of mating cycles. The robust housing and dual-row configuration distribute mating forces across 56 contacts, reducing per-pin stress and improving mechanical retention in vibration-prone industrial and telecom enclosures.
When is the SFM-128-02-SM-D a better choice than a through-hole SFM variant for a mezzanine design?
The surface-mount SFM-128-02-SM-D is preferred over through-hole variants when the PCB stack-up has four or more signal layers and drilling 56 via holes would disrupt inner-layer routing. It is also the right choice for two-sided SMT boards where wave soldering is not used, since reflow soldering bonds all 56 pads simultaneously, achieving more consistent joint quality than selective soldering of through-hole pins.
