What are the key features of SMS-118-01-S-D?
- 36-position through-hole micro socket with 0.050" x 0.100" pitch offering higher contact density than standard .100" single-pitch connectors
- 30 µin gold over 50 µin nickel mating contact finish provides low contact resistance below 20 mΩ and extended mating cycle durability
- Tiger Buy contact designation indicates pre-qualified high-volume inventory availability for uninterrupted production supply chains
What is SMS-118-01-S-D used for?
The SMS-118-01-S-D is designed for high-density signal interconnects in embedded computing boards, FPGA daughter cards, and instrumentation modules where micro-pitch socket connections save significant PCB area. Its 0.050" x 0.100" pitch accommodates routing on fine-pitch PCB grids common in 6-layer to 10-layer boards. The through-hole design provides strong mechanical retention compared to surface mount alternatives, making it suitable for test and measurement equipment subject to repeated mating cycles.

Frequently Asked Questions
What dual-pitch specification does the SMS-118-01-S-D use and why does it reduce PCB footprint compared to standard .100" sockets?
The SMS-118-01-S-D uses a 0.050" (1.27 mm) x 0.100" (2.54 mm) dual pitch, placing contacts 1.27 mm apart in the row direction versus 2.54 mm for standard .100" sockets. For a 36-position single-row socket, this reduces the body length to approximately 0.9 inches compared to 1.775 inches for a .100" pitch equivalent, saving nearly 50% of board edge length in dense header layouts.
How does the 30 µin gold over 50 µin nickel contact finish on SMS-118-01-S-D compare to lower-gold plating options for high-cycle applications?
The 30 µin gold mating finish on the SMS-118-01-S-D is rated for 500 or more mating cycles before contact resistance increases beyond 20 mΩ, compared to 15 µin gold variants that typically degrade after 200 cycles. For test fixtures or field-serviceable boards that are mated and unmated frequently, the thicker 30 µin gold plating significantly extends connector service life and reduces maintenance costs.
In which embedded or instrumentation designs does the SMS-118-01-S-D through-hole mounting provide an advantage over a surface mount micro socket?
The through-hole (TH) mounting of the SMS-118-01-S-D anchors contacts into plated through-holes, yielding pull-out forces above 30 N per row that surface mount pads alone cannot match. This is advantageous in portable test instruments, ruggedized data loggers, and daughter-card assemblies that experience frequent mating cycles or vibration up to 15g in transportation or industrial environments.
What does the Tiger Buy Contact feature of SMS-118-01-S-D mean for procurement planning?
The Tiger Buy Contact designation from Samtec indicates that SMS-118-01-S-D is a pre-stocked, high-volume catalog part maintained with buffer inventory to support expedited ordering with lead times as short as 1 to 3 business days. For production runs requiring 1000 pieces or more, this availability status reduces supply chain risk compared to standard or custom-order Samtec connectors with 4 to 8 week lead times.
