Product details

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.

Frequently asked questions

Is the 513870578 compatible with USB OTG (On-The-Go) devices?

Yes, the connector is specified for USB 2.0 OTG, which means it supports the host/peripheral negotiation protocol used in OTG devices like smartphones and tablets.

Is the 513870578 shielded?

Yes, the connector is shielded with a copper alloy shell, which provides EMI containment and noise rejection for the USB data lines.
