Applications
Samtec SMS-119-01-S-D is used in high-density board-to-board interconnect applications in test-and-measurement instruments, FPGA development platforms, and compact embedded computing modules where 38 signal channels must be routed through a 0.95 inch micro socket footprint. The 0.050 x 0.100 inch mixed pitch accommodates both signal and power contacts in a single through-hole socket, reducing wiring complexity in medical device subassemblies and industrial sensor hubs. Its gold-plated contacts support reliable mating in laboratory instruments and ATE (automatic test equipment) sockets that undergo frequent board insertion and extraction.

Frequently Asked Questions
How does the 0.050 x 0.100 inch mixed pitch of SMS-119-01-S-D enable higher pin density than standard 0.100 inch sockets?
SMS-119-01-S-D uses a 0.050 x 0.100 inch mixed pitch (1.27 mm x 2.54 mm) that halves the row-to-row spacing compared to a standard 0.100 inch square-grid socket. This allows 38 contacts within a body length of 0.95 inch and body depth of 0.335 inch, providing roughly 2x the connection density of an equivalent standard 0.100 inch through-hole socket in the same PCB footprint.
What mating cycles does the gold (30 µin) over nickel plating in SMS-119-01-S-D support for test fixture applications?
The 30 µin gold over 50 µin nickel mating contact finish in SMS-119-01-S-D is rated for at least 100 mating cycles per IPC and MIL connector standards at this plating thickness. For ATE (automatic test equipment) or laboratory test fixture applications that perform dozens of board insertions weekly, this plating level maintains contact resistance below 20 mΩ throughout service life, reducing false-failure rates in functional test stations.
Is SMS-119-01-S-D RoHS compliant, and what lead-free termination does it use for wave soldering?
Yes, SMS-119-01-S-D carries a Pbfree code indicating full RoHS compliance. The through-hole termination uses Tin (Sn) with Nickel (Ni) barrier plating, which is compatible with standard lead-free wave soldering at 260°C peak temperature. This Tin/Nickel combination provides a solderable surface with good adhesion and meets REACH and RoHS 2 substance restrictions for 38-position connectors shipped into EU and global markets.
What is the procurement lead time and lifecycle expectation for SMS-119-01-S-D in long-term production planning?
SMS-119-01-S-D has a YTEOL (Years to End of Life) metric of 9.15 years, indicating a long remaining lifecycle that reduces obsolescence risk in 5-year to 10-year production programs. For procurement planning, through-hole micro sockets like the SMS series typically carry moderate lead times of 4 to 12 weeks depending on quantity, making early-stage BOM validation and safety stock planning advisable for programs requiring continuous 38-position socket supply.
