Key Features

  • 2.00 mm pitch dual-row socket design compatible with standard SQ/SQT mating header families for reliable board-to-board connections
  • Gold flash over nickel contact finish on 3-position FLEXYZ contacts providing low-resistance, corrosion-resistant mating interfaces
  • Rugged PCB socket construction rated for repeated mating cycles, supporting industrial and test-equipment assembly applications
  • Cost-effective Tiger Buy contact option available for high-volume procurement with 1-week factory lead time
  • Compact 0.249 x 0.25 inch footprint enabling dense connector placement in space-constrained PCB layouts

Applications

The SQT-103-01-F-D is used in industrial control systems, test and measurement equipment, and embedded computing modules where low-profile, reliable board-to-board mating at 2.00 mm pitch is required. Its rugged FLEXYZ contacts tolerate vibration and repeated plug-and-unplug cycles found in field-replaceable module designs. The cost-effective Tiger Buy contact option makes it suitable for high-volume consumer and industrial PCB assembly.

Frequently Asked Questions

What pitch and contact finish does the SQT-103-01-F-D use, and how do these specs affect signal integrity?

The SQT-103-01-F-D uses a 2.00 mm pitch with gold flash over nickel contact finish on each of its 3 positions. The gold finish provides low contact resistance typically under 20 milliohms, which is critical for maintaining signal integrity in high-cycle mating applications and preventing oxidation in humid industrial environments.

For a vibration-prone industrial enclosure design, how does the FLEXYZ contact technology in the SQT-103-01-F-D improve reliability?

SAMTEC's FLEXYZ contact in the SQT-103-01-F-D is engineered to maintain contact force over thousands of mating cycles and under vibration loads common in industrial enclosures. The compliant contact geometry accommodates minor PCB-level misalignment up to several hundredths of a millimeter, reducing intermittent connection failures in 24 V DC industrial control systems.

What is the body footprint of the SQT-103-01-F-D and what PCB layout clearance is needed for a dual-row 3-position socket at 2.00 mm pitch?

The SQT-103-01-F-D body measures 0.249 inches long by 0.25 inches deep, with a 0.158-inch breadth. For a dual-row 3-position socket at 2.00 mm pitch, designers should allocate at least 8 mm of PCB clearance in the mating axis and follow SAMTEC land pattern recommendations to ensure proper solder joint formation and mating header insertion depth.
