Gold plating on the contacts handles the 1500 mating cycles this part is rated for, which is well above the 500-cycle baseline for a basic USB connector; this one was built for repeated plug-unplug duty in a panel or device that sees regular field access. ## Mounting and Environment The mounting is a hybrid — surface mount, right angle with through-hole support — listed as both Surface Mount, Right Angle and Through Hole. That means the signal pins reflow onto the board pads while the shell legs solder into plated through-holes for mechanical retention. The operating temperature range is 0°C to 50°C, which is tight: this connector was designed for indoor consumer or commercial equipment, not an automotive cabin or an outdoor enclosure. No direct replacement is documented, so a cross-reference search or a board redesign to a current USB-A connector may be needed for new production. The 1.5A per contact rating at 30VDC is standard for a USB 2.0 power line — enough for a 7.5W device draw across the VBUS pin, but not for a high-power charging port. The 1500 mating cycles mean the gold plating is thick enough to survive years of daily connect-disconnect in a field-service scenario; a standard tin-plated USB connector would fret and fail long before that count. The shielded steel shell mates with the receptacle's ground fingers to bleed common-mode noise before it reaches the differential data pair, which is why USB 2.0 signal integrity holds up to the 480 Mbps data rate without extra ferrites.","metaTitle":"TE 1734028-2 USB-A Plug, Shielded, 4 Contacts, Obsolete","metaDescription":"TE Connectivity 1734028-2 USB-A (USB TYPE-A) plug, 4 contacts, USB 2.0, shielded, right-angle SMT.
