USB Mini B Receptacle for OTG and Portable Device Interfaces
The Molex 513870578 is a 5-contact USB mini B receptacle from the 51387 series, designed for USB 2.0 On-The-Go (OTG) applications.
Mounting and Termination for Assembly Planning
This receptacle mounts horizontally (right-angle) to the PCB using surface-mount solder tails, with through-hole options also listed.
Shielding and Signal Integrity for USB 2.0
The connector is explicitly shielded, which helps contain radiated emissions and reject external noise on the differential data pair — important for maintaining signal integrity at USB 2.0 data rates. The 1 A current rating per contact is adequate for the VBUS power line in standard USB 2.0 applications, including OTG devices where the port may supply or sink power.
Compliance and Operating Range
Rated for 0°C to 50°C operating temperature, the connector is intended for indoor consumer and commercial electronics rather than extended-temperature industrial environments. ROHS3 compliance is confirmed.
