Application Scenarios
-
Ultra-Thin Wearables & Smartwatches : The 0.80mm mid-mount design sinks into the PCB, drastically reducing the overall device thickness while providing a standard, user-friendly charging port.
-
Portable IoT & Tracking Devices : Offers a reliable 3A power connection for compact, battery-operated IoT sensors that require frequent recharging but lack the internal space for full 24-pin receptacles.
-
Handheld Medical Instruments : Delivers 10,000-cycle durability for diagnostic tools used in clinical environments, ensuring long-term reliability for daily charging cycles.
-
Consumer Audio & Wireless Earbud Cases : Strips away unnecessary high-speed data costs while maintaining the premium feel and reversible plugging convenience of Type-C for charging cases.
Frequently Asked Questions
Does this 6-pin USB-C receptacle support USB 2.0 data transfer?
No. This 6-pin receptacle is dedicated to power delivery and charging (VBUS, GND, and CC1/CC2 pins). It omits USB 2.0 (D+/D-) and SuperSpeed data lines to maximize PCB space savings and reduce BOM costs.
What is the primary advantage of a mid-mount (sink board) design?
A mid-mount connector sits partially inside a cutout in the PCB (in this case, sinking 0.80mm). This reduces the above-board height (Z-axis profile), making it essential for ultra-thin product designs.
What are the electrical power ratings for this 6-pin receptacle?
The connector is rated for a maximum of 5V AC with 3.0A current capacity on the VBUS lines (0.25A for other pins), making it ideal for standard 5V/3A fast-charging circuits in compact devices.
Are 3D CAD models or step files available for my mechanical engineering team?
Yes, we provide 2D drawings and 3D STEP files for all our OEM connectors to facilitate seamless DFM integration. Please submit an RFQ to request the technical files.
What is the minimum order quantity (MOQ) and packaging method?
These SMT connectors are supplied in Tape & Reel packaging, optimized for automated pick-and-place assembly. Please contact our sales team for tier pricing and standard factory MOQ.
Overview and Application Notes
-
Overview: The EU06FB3N11319 is a high-reliability 6-pin USB Type-C mid-mount (sink-board 0.80mm) female receptacle engineered for ultra-compact and low-profile electronic designs. By focusing on a dedicated 6-pin power-charging architecture (VBUS, GND, CC1, CC2) and eliminating unused high-speed data pins, this connector significantly reduces Z-axis height and overall BOM cost. It supports up to 3.0A current on VBUS lines at 5V AC max and is built with a high-temperature LCP (UL 94V-0) housing, gold/tin-plated copper alloy contacts, and a nickel-plated stainless steel shell and mid plate. Rated for 10,000 mating cycles and an operating temperature range of -55°C to +85°C, it delivers a robust, space-saving charging interface for portable electronics, IoT devices, and smart hardware.

Application Notes:
-
PCB Cutout & Sink Height: The receptacle features a 0.80mm mid-mount (sink board) structure. Ensure the board edge cutout and pad dimensions strictly follow drawing EU06FB3N11319 to maintain coplanarity and smooth shell grounding.
-
Power-Only (Charging) Pin Layout: This simplified 6-pin layout comprises VBUS (3A), GND, and CC1/CC2 pins. It is designed for standard power supply and charging negotiations without USB 2.0 (D+/D-) or SuperSpeed data transmission lines.
-
Shell DIP Leg Retention: Fully solder the 4 outer shell DIP tabs into the PCB locating slots to maximize mechanical peel strength and resist lateral mating stress.
-
CC Line Termination: Integrate standard 5.1kΩ pull-down resistors on the CC pins within your PCBA circuitry to ensure reliable USB Type-C device detection and 5V power negotiation.
