Frequently Asked Questions
What are the body dimensions of SMS-125-02-G-D, and how many contacts does it provide?
SMS-125-02-G-D has a body length of 1.25 inches (approximately 31.75 mm), a breadth of 0.22 inch, and a depth of 0.335 inch. With 25 positions in a dual-row configuration, it provides 50 total contacts at a 2.54 mm pitch, fitting standard dual-row male headers used across embedded computing boards, industrial modules, and modular development platforms.
Which contact finish does SMS-125-02-G-D use, and how does it affect connector longevity in repeated-mating applications?
SMS-125-02-G-D applies 20 µin gold over 50 µin nickel on the mating contacts and gold over nickel on the termination side. This dual-surface gold finish provides excellent resistance to oxidation and fretting corrosion, maintaining low contact resistance across repeated insertion cycles in daughter-card and evaluation board sockets where connectors are mated and unmated frequently during development and test.
Is SMS-125-02-G-D a Tiger Buy product, and what does that mean for procurement lead times?
Yes, SMS-125-02-G-D carries the SAMTEC Tiger Buy designation, indicating it is stocked in high volume at SAMTEC warehouses for rapid order fulfillment. Tiger Buy parts are typically available for same-day or next-day shipping through authorized distributors, making SMS-125-02-G-D an excellent choice for engineering prototyping, low-volume production runs, and maintenance situations where a 50-contact 2.54 mm pitch dual-row socket is needed quickly.
