The TE Connectivity 1735183-1 is a 29-position SAS plug designed for board-edge, right-angle surface-mount attachment.
What the 30µ" Gold Means for the Duty
In a SAS interconnect that sees drive swaps or test-bench reconnects, that thickness keeps contact resistance stable. Tin or thin-gold contacts would fret after a fraction of the cycles.
Right-Angle SMT — Board Layout Reality
The right-angle SMT mounting means the connector's solder tails emerge from the side of the body, not the bottom. The footprint is a row of pads along the board edge, and the connector body overhangs the edge. That geometry demands a specific keep-out zone on the PCB — no components or traces within about 5 mm of the edge where the connector sits. Through-hole variants like the 1735164-1 use plated through-holes instead, which changes the routing layer access.
The 1735164-1 is a 29-position SAS receptacle with through-hole mounting and a board lock — it's the mating half for this plug if you need a right-angle board-mount receptacle, but the through-hole tails require a different PCB footprint and a wave-solder pass. The 1735368-1 is also a 29-position SAS receptacle but uses press-fit termination, which avoids solder entirely for a backplane assembly. Both are active parts, but neither is a drop-in substitute for the 1735183-1's SMT plug — the mounting method and plug-versus-receptacle orientation are the decision points.
