USB Mini-B Receptacle for Board-Edge Integration
It carries 5 contacts, rated 1A per contact at 30VAC, with a shielded shell and gold-plated contacts that hold up to 5000 mating cycles — well above the typical 1500-cycle spec for a consumer USB port.
Last Buy Status — What It Means for Sourcing
Hirose has marked the UX60SC-MB-5ST(80) as Last Buy. That means the factory has stopped taking new orders for standard production, and the remaining inventory in the distribution channel is the final available stock. Once that stock is exhausted, the only route to this part will be surplus or broker inventory with traceable date codes. No official successor or drop-in replacement is listed by Hirose for this order code. If your BOM calls for this exact mini-B receptacle, the procurement window is narrow — sourcing now against an RFQ is the move. Confirm the quantity and lead time at quote; the date code on any available stock will tell you how long it has been sitting.
What the 5000-Cycle Rating Means for Your Assembly
The 5000 mating cycles on this connector are a genuine durability spec, not a marketing number. The shielded shell and copper alloy shield material also contribute to consistent ground reference across repeated mates, which matters for USB 2.0 signal integrity at 480 Mbps. If your design sees frequent reconnection — a handheld programmer, a diagnostic tool, a portable instrument — this receptacle will outlast the cheaper alternatives.
The horizontal mounting feature means the connector body sits flat on the PCB, with the mating face oriented toward the board edge. For the exact footprint dimensions, the product drawing is the reference; the base product number UX60SC groups the variant-specific order codes that share the same PCB layout. The tape-and-reel packaging (Cut Tape also available) feeds into a standard pick-and-place line without manual handling.
