Key Features
- 84-position dual-row SMT socket at 1.27 mm (0.050") pitch for high-density signal routing in mezzanine and FPGA carrier board designs
- Extended -SM tail option provides additional PCB contact length for improved solder joint mechanical strength under vibration and thermal cycling
- Gold-plated contacts rated 1A per pin supporting 100+ mating cycles for production and field-serviceable board-to-board stacking
Applications
The SFM-142-T2-SM-D-A is suited for board-to-board stacking in FPGA daughter cards, embedded processor modules, and test platform carrier boards requiring 84 robust connections at 1.27 mm pitch with enhanced solder retention. The extended tail option is particularly valuable in industrial and aerospace applications subject to mechanical vibration, where extra solder fillet height improves joint fatigue life.

Frequently Asked Questions
What does the -SM suffix in SFM-142-T2-SM-D-A indicate about the contact tail?
The -SM suffix designates an extended solder tail in the SFM-142-T2-SM-D-A, providing a longer contact leg that increases solder fillet volume and wetting area. This improvement in mechanical retention is beneficial in applications subject to vibration or thermal cycling, where a standard tail may have insufficient fatigue strength over thousands of thermal excursions between -40°C and +85°C.
How many signal connections does SFM-142-T2-SM-D-A provide, and what is the per-pin current rating?
The SFM-142-T2-SM-D-A provides 84 positions in a dual-row 1.27 mm pitch configuration, with each gold-plated contact rated at 1A continuous current. At full load across all 84 pins, the connector can carry a combined 84A if power pins are uniformly distributed, though thermal derating should be applied for densely loaded power rails.
For a ruggedized industrial FPGA module expected to operate between -40°C and 85°C, does SFM-142-T2-SM-D-A meet the environmental requirements?
Yes, the SFM-142-T2-SM-D-A is rated for operating environments spanning -40°C to 85°C. Its extended -SM solder tail improves solder joint fatigue resistance across this temperature range, and gold-plated contacts resist oxidation even in mildly corrosive industrial environments, maintaining contact resistance within specification for reliable signal integrity.
Which SAMTEC header series mates with SFM-142-T2-SM-D-A for a 84-pin board stack?
The SFM-142-T2-SM-D-A mates with SAMTEC TSM series and SSM series 1.27 mm pitch dual-row headers in either through-hole or SMT configurations. These headers are available in multiple post lengths to achieve board-to-board stacking clearances from approximately 5 mm to 20 mm, enabling flexible PCB stack-up designs for embedded computing modules.
