What are the key features of SMS-109-01-T-D?

  • 18-position dual-row micro socket at 0.050" x 0.100" pitch enabling high-density through-hole mating in tight PCB layouts
  • Female socket contact geometry with tin-over-nickel barrier finish providing reliable low-resistance mating across temperature cycles
  • Compact 0.45" body length designed for space-constrained embedded boards requiring secure removable pin connections

What is SMS-109-01-T-D used for?

The SMS-109-01-T-D micro socket is commonly used for removable daughter card connections, debug headers, and IC socket adapters in embedded computing, instrumentation, and aerospace avionics prototyping. Its 18-position, 0.050" x 0.100" pitch footprint allows dense signal routing in compact PCB areas where standard 0.100" sockets would exceed available space. Design engineers choose this socket for field-replaceable module interfaces where plug-and-play serviceability and reliable tin-over-nickel contacts are essential.

Frequently Asked Questions

What contact pitch does the SMS-109-01-T-D use and how does it compare to standard 0.100" sockets?

The SMS-109-01-T-D uses a 0.050" x 0.100" dual-row pitch, which is half the column spacing of standard 0.100" sockets, enabling 18 contacts to fit within a body length of only 0.45" — roughly half the board space a conventional 18-position 0.100" socket would require.

Which termination finish does the SMS-109-01-T-D use and how does it affect solderability?

The SMS-109-01-T-D termination uses tin with a nickel barrier, which is fully compatible with standard lead-free solder processes at reflow temperatures up to 260°C and provides a corrosion-resistant barrier that maintains solder joint integrity over the product lifetime.

For a compact avionics or instrumentation PCB, what body dimensions must be reserved for the SMS-109-01-T-D?

The SMS-109-01-T-D measures 0.45" (body length) x 0.22" (breadth) x 0.335" (depth), so a PCB keep-out area of approximately 11.4 mm x 5.6 mm x 8.5 mm must be allocated per socket to clear adjacent components and allow mating connector insertion.
