What are the key features of SMS-140-01-G-D?
- 80 positions in a dual-row layout at 0.050 inch x 0.100 inch pitch for ultra-high-density through-hole mounting
- Gold (20 µin) over nickel (50 µin) mating contacts provide low contact resistance and reliable multi-cycle mating
- Through-hole socket body (2 inch length) with robust anchor for mechanical retention in vibration environments
- TIGER BUY designation indicates stock availability for immediate procurement without extended lead times
- Lead-free (Pb-free) construction meets RoHS and REACH compliance requirements for global markets
- Dual-row (D) configuration routes 80 signals through a compact 0.22 inch wide body
What is SMS-140-01-G-D used for?
SMS-140-01-G-D is used in test and measurement fixtures, prototyping backplanes, and legacy through-hole PCB assemblies where 80 signal contacts must be reliably socketed in a 0.050" x 0.100" pitch dual-row format. Its through-hole construction provides mechanical strength for applications subject to frequent mating cycles, making it suitable for development boards, burn-in sockets, and field-replaceable module connectors in industrial equipment.

Frequently Asked Questions
What does the 0.050 inch x 0.100 inch mixed pitch of SMS-140-01-G-D mean for PCB layout, and how does it differ from a uniform 0.100 inch grid?
The 0.050 inch x 0.100 inch pitch means that SMS-140-01-G-D positions contacts at 0.050 inch (1.27 mm) intervals along the rows but spaces the two rows 0.100 inch (2.54 mm) apart center-to-center. This staggered pitch allows 80 contacts to be packed into a body only 0.22 inch wide, roughly half the width of an equivalent uniform 0.100 inch dual-row connector.
How do the 20 µin gold contacts in SMS-140-01-G-D hold up in a burn-in socket application with thousands of mating cycles?
Gold (20 µin) over nickel (50 µin) provides a hard, corrosion-resistant mating surface that typically supports hundreds of mating cycles while maintaining contact resistance below a few milliohms. For burn-in sockets that may see thousands of cycles, designers should verify the specific wear spec from Samtec's datasheet, as 20 µin gold is rated lower than 30 µin or 50 µin gold options.
For a PCB with strict sourcing requirements, how quickly can SMS-140-01-G-D be delivered?
SMS-140-01-G-D carries a Samtec TIGER BUY designation and a listed factory lead time of 1 week, indicating it is stocked or quickly buildable. This fast availability is valuable when prototyping or sustaining production that cannot tolerate the 8-to-12-week lead times common for specialty connectors with custom options.
Does the through-hole mounting style of SMS-140-01-G-D offer a mechanical advantage over surface mount socket alternatives in vibration-prone enclosures?
Yes. Through-hole pins soldered into plated through-holes provide a stronger mechanical solder joint than surface mount pads, anchoring the 2-inch-long SMS-140-01-G-D body against vibration and axial mating forces. This is especially important for 80-position connectors where the cumulative insertion and extraction force across all contacts can stress a surface mount solder joint significantly.
