Stacked USB-A Receptacle, 18 Contacts, USB 3.2 Gen 1 — the Obsolete Cross-Reference Target
The TE Connectivity 1932355-1 is a stacked USB-A (USB TYPE-A) receptacle housing two USB 3.2 Gen 1 (formerly USB 3.0 / SuperSpeed) ports in a single through-hole, right-angle package. With 18 contacts total — 9 per port — it carries the full SuperSpeed signal set plus power and ground for each downstream connection. The blue insulation colour is the standard visual marker for USB 3.0 SuperSpeed receptacles, distinguishing it from the black USB 2.0 variants.
5000 Mating Cycles — Built for High-Duty-Cycle Panel Mount
The 5000-cycle rating is the standout mechanical spec. Standard USB receptacles from commodity suppliers are typically rated 1500 cycles; this TE part was specced for equipment that sees daily plug-unplug — think test fixtures, kiosk ports, or industrial HMI panels where the connector outlasts the device enclosure. The shielded shell in copper alloy provides the ground return for the SuperSpeed differential pairs and bleeds EMC before it reaches the PCB ground plane.
Obsolete — What Crosses to It?
The 1932355-1 is marked Obsolete. The base product number 1932355 covers the family; variant 1932355-2 may carry a different plating or packaging, but without a documented form-fit-function cross-reference from TE, assuming pin-compatibility is a risk.
Board Layout and Termination Checklist
The 18 through-hole solder tails include the signal pins for both ports plus the shield ground legs. The board lock requires a corresponding plated through-hole in the PCB — typically a non-functional pad tied to ground — to anchor the connector during reflow and against cable strain. Solder termination is standard wave-solder or selective-solder process; the copper-alloy shell wets well with leaded or lead-free solder. Confirm the PCB footprint matches the TE product drawing before committing the board layout — the 18-pin dual-port stack has a specific keep-out for the shield ground legs and board lock anchors.
