What are the key features of SQT-106-03-L-D?
- FlexYZ Tiger Eye contact system provides multi-directional compliance and positive gold mating contact in a 12-position dual-row socket, reducing insertion force while maintaining reliable electrical connection
- Gold mating finish over nickel ensures ultra-low contact resistance across thousands of mating cycles, critical for high-cycle test fixtures and modular board-swap applications
- Compact body (0.486 × 0.158 × 0.25 inch) with RoHS-compliant, Pb-free tin-on-nickel termination supports modern environmental standards without sacrificing mechanical integrity
What is SQT-106-03-L-D used for?
The SQT-106-03-L-D is designed for modular board-to-board connections in embedded computing, FPGA daughter cards, and industrial I/O expansion boards requiring 12-position dual-row reliability in a compact socket form factor. The FlexYZ Tiger Eye contact technology makes it especially suitable for high-cycle test and measurement fixtures where consistent contact performance across hundreds of insertions is required. Its gold mating surface and RoHS-compliant build align with both commercial and industrial application requirements.

Frequently Asked Questions
What makes the FlexYZ Tiger Eye contact in SQT-106-03-L-D different from a standard socket contact?
The FlexYZ Tiger Eye contact in the SQT-106-03-L-D provides multi-directional compliance, typically tolerating up to ±0.15 mm of mating pin misalignment, and uses a gold mating surface for contact resistance below 20 mΩ—far outperforming standard tin-on-tin contacts that can exceed 50 mΩ after repeated cycling.
How many positions does the SQT-106-03-L-D provide, and what is the connector body size?
The SQT-106-03-L-D provides 12 total positions in a dual-row socket layout. The body measures 0.486 inches long, 0.158 inches wide, and 0.25 inches deep, making it suitable for high-density board connectors where multiple 12-position sockets must be placed within millimeters of each other.
Is the SQT-106-03-L-D a suitable replacement in an existing design that uses a standard 12-position dual-row socket?
It can be a drop-in form factor match if the mating header pitch is compatible with SAMTEC SQT series standards. The lead-free tin-on-nickel termination and gold mating surface are cross-compatible with gold or tin-finished mating pins, and the RoHS-compliant build ensures it meets current regulations without redesigning the PCB footprint.
