What are the key features of SMS-120-01-T-D?
- 40-position dual-row micro socket with unique 0.050 x 0.100 inch mixed pitch for space-saving through-hole PCB mounting
- Tin over nickel barrier contact finish providing reliable low-insertion-force mating across hundreds of plugging cycles
- Compact 1-inch body length with 0.22 inch breadth enabling tight PCB layouts while maintaining full 40-pin connectivity
What is SMS-120-01-T-D used for?
The SMS-120-01-T-D through-hole micro socket is used in prototype and production PCBs where a 40-position removable socket connection is needed for daughter card modules, test fixtures, or plug-in daughter boards at 0.050 x 0.100 inch mixed pitch. Its through-hole termination provides robust mechanical retention suitable for hand soldering and wave soldering processes in industrial control boards and instrumentation hardware. The compact 1-inch body length enables placement in tight board areas where standard 0.100-inch pitch sockets would consume excessive space.

Frequently Asked Questions
What is the mixed pitch of the SMS-120-01-T-D and why is it used?
The SMS-120-01-T-D uses a unique 0.050 x 0.100 inch mixed pitch, meaning contacts are spaced 0.050 inch (1.27mm) in one axis and 0.100 inch (2.54mm) in the other axis across the dual rows. This mixed pitch accommodates specific mating plug families while achieving higher contact density than pure 0.100 x 0.100 inch sockets in the 40-pin format.
How many positions does the SMS-120-01-T-D have and what contact finish is used on the mating interface?
The SMS-120-01-T-D has 40 total positions in a dual-row layout and uses tin (Sn) plating on the mating interface with a nickel (Ni) barrier layer on the termination leads. Tin contact finish provides adequate conductivity for low-frequency signals and general purpose digital interfaces, with an insertion force well below 1N per contact for gentle mating.
Which prototype and production PCB applications suit the SMS-120-01-T-D micro socket?
This 40-position through-hole socket is well suited for SOM (System-on-Module) carrier boards, test jig sockets, development kit daughtercard connectors, and removable peripheral interface modules where a robust through-hole mount is preferred over surface mount. The 1-inch body length and 0.335-inch depth fit within standard DIP socket footprints adjacent to ICs on mixed-component boards.
What is the factory lead time and expected lifetime for the SMS-120-01-T-D?
The SMS-120-01-T-D has a factory lead time of 4 weeks and 1 day from the manufacturing date for non-stocked quantities, with a component lifetime (YTEOL) of approximately 9.15 years. For urgent procurement, in-stock quantities at authorized distributors allow same-day or next-day worldwide shipping without waiting for the standard factory lead time.
