Applications
The SAMTEC SMS-120-02-T-D through-hole micro socket is used for dense board-to-board and wire-to-board interconnect in embedded systems, single-board computers, and development platforms where 40 signals must be routed across the 0.050" x 0.100" mixed pitch. Its 1" body length and dual-row female socket design make it compatible with standard IC socket footprints used in FPGA prototyping boards, microcontroller development kits, and test fixture backplanes. The tin-over-nickel contacts support standard wave soldering processes in industrial automation controllers, data logging instruments, and educational electronics platforms requiring reliable field-replaceable daughter card connections.

Frequently Asked Questions
What is the pitch, pin count, and contact finish of the SAMTEC SMS-120-02-T-D micro socket?
The SMS-120-02-T-D provides 40 total positions in a dual-row configuration with a mixed pitch of 0.050" between rows and 0.100" (2.54 mm) along the row. Contact termination finish is tin over nickel (Sn/Ni) supporting wave soldering at up to 260°C. The 1.00" body length with 0.22" breadth fits compact through-hole footprints used in development and production boards.
Which header pin styles are compatible with SMS-120-02-T-D for modular daughter card connections?
The SMS-120-02-T-D female micro socket mates with standard dual-row 0.050" x 0.100" pitch male headers, including SAMTEC's TSW and HPM series pin strips with 40-position dual-row configurations. The 0.100" row pitch is compatible with standard 2.54 mm DIP and SIP header families, providing flexibility for connecting daughter cards, plugin modules, and daughterboards in development systems using off-the-shelf 40-pin header connectors widely available in embedded computing kits.
What does the YTEOL rating of 9.15 years mean for SMS-120-02-T-D procurement planning?
The YTEOL (Years to End of Life) value of 9.15 years for SMS-120-02-T-D indicates SAMTEC's commitment to manufacturing this connector for at least 9 more years from the current date, providing procurement confidence for industrial and scientific instruments with extended production lifecycles. This rating is important when designing products with 5-10 year production runs that depend on component availability, allowing designers to avoid costly connector re-qualification mid-production with 40-position dual-row sockets.
For a prototype FPGA expansion board, how does SMS-120-02-T-D enable repeatable daughter card connection?
The SMS-120-02-T-D's 40-pin dual-row female socket at 0.050" x 0.100" pitch accepts standard 40-pin male headers used on FPGA expansion boards and IO mezzanine cards, enabling plug-in daughter cards to be swapped without soldering. The tin-over-nickel contacts support hundreds of insertion cycles in lab and field-test environments, and the 1.00" body length with 40 positions routes up to 40 digital IO, SPI, I2C, or LVDS pairs to daughter modules in compact embedded prototyping systems.
