The JST UB-MC5ABR3-SD204-4S-1-TB NMP is a USB micro AB receptacle from the JST UB series, a 5-contact surface-mount connector designed for the micro USB interface standard.
Key Ratings and the Selection Decision
The current rating is listed as 0.5A, 1A, 1.8A — these are per-contact limits that vary by the number of contacts carrying current simultaneously.
Lifecycle Reality: Obsolete Status
This part is officially listed as Obsolete. A cross-reference search against other micro AB receptacles with the same 5-contact SMT right-angle footprint is the practical next step for a BOM-line substitution.
Mounting and Termination Detail
Termination is solder — surface-mount, right-angle. The mounting feature is horizontal, meaning the connector body sits flat on the board with the mating slot facing the board edge. The steel, stainless shell/shielding material provides EMI containment, though the connector is listed as unshielded, so the shell acts as a mechanical anchor rather than a continuous RF shield. The Tape & Reel and Cut Tape packaging options suit both prototype hand-assembly and production pick-and-place runs.
