Key Features
- 80-position dual-row layout on 0.050" (1.27 mm) pitch delivers high-density board-to-board connectivity in a 2.075-inch body length
- Tiger Eye contact technology provides reliable wiping action across repeated mating cycles for long service life
- Gold-plated mating contacts (30 microinches) minimize contact resistance and resist oxidation in harsh environments
- PEG board mounting option stabilizes connector placement during SMT reflow for consistent solder joint quality
Applications
The SFM-140-02-SM-D-A is suited for high-density mezzanine board-to-board interconnects in telecom switching cards, FPGA development platforms, and industrial control backplanes requiring 80 signal or power contacts. Its 0.050" pitch and 2.075-inch body length enable compact multi-signal routing in space-constrained enclosures. The surface mount design with peg retention supports automated SMT assembly in high-reliability production environments.

Frequently Asked Questions
What is the contact finish on the SFM-140-02-SM-D-A mating interface, and why does it matter for reliability?
The SFM-140-02-SM-D-A uses gold-plated mating contacts with a 30 microinch (0.76 µm) gold finish. This finish provides low and stable contact resistance over thousands of mating cycles, resists oxidation, and is essential for reliable high-speed signal integrity in applications such as telecom line cards and FPGA mezzanine boards.
How does the 80-position SFM-140 compare physically to smaller SFM series parts for board layout planning?
The SFM-140-02-SM-D-A has a body length of 2.075 inches (approximately 52.7 mm), body breadth of 0.145 inch, and body depth of 0.185 inch. This is significantly larger than a 4-position SFM-102, which measures under 5 mm. Designers routing 80 signals in dual-row at 1.27 mm pitch must allocate a 53 mm keep-out zone along the mating edge of the PCB.
Can the SFM-140-02-SM-D-A be used in applications requiring 2-week lead-time procurement from SAMTEC?
Yes, the factory lead time for the SFM-140-02-SM-D-A is listed as 2 weeks and 1 day, which is relatively short for a high-position-count connector. This makes it suitable for low-to-medium-volume production builds and prototype runs. Global distribution stock may reduce effective lead time to same-day or next-day shipment for standard order quantities.
