Frequently Asked Questions
What contact finish does the SMS-135-02-G-D use, and how does it affect mating reliability?
The SMS-135-02-G-D uses gold (20 micro-inch minimum) over nickel (50 micro-inch minimum) contact finish across all 70 positions. This finish provides excellent corrosion resistance and maintains contact resistance below 20 milliohms even after hundreds of mating cycles, making it suitable for field-replaceable daughtercard applications requiring long service life.
For a 70-signal daughtercard interface using 0.050" x 0.100" pitch, why choose SMS-135-02-G-D over a standard 0.100" pitch socket?
The SMS-135-02-G-D's 0.050" x 0.100" pitch allows accommodating 70 contacts within a body length of 1.75 inches, compared to a standard 0.100" pitch socket that would require nearly double the board length. This compact footprint is critical for space-constrained PCB layouts in portable instruments and embedded computing cards.
What procurement advantages does the Tiger Buy designation provide for SMS-135-02-G-D buyers?
The Tiger Buy designation on SMS-135-02-G-D indicates that Samtec maintains elevated safety stock levels, typically reducing lead times from the standard 2-week factory lead time to same-day or next-day shipment for authorized distributors. For production runs requiring 70-position micro sockets, this reduces supply-chain risk and supports lean inventory strategies.
