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
Is this 6-pin connector compatible with standard 24-pin USB-C cables?
Yes. The physical interface is fully intermateable with all standard USB Type-C male plugs. The 6-pin design simply omits the high-speed data pins internally to save space and reduce OEM 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.
Does this receptacle support USB Power Delivery (PD) fast charging?
Yes. It is rated for 3A on the VBUS pins. When paired with the correct CC pin circuitry on your PCBA, it can safely support standard PD profiles up to 60W (20V/3A).
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 highly specialized 6-pin USB Type-C mid-mount (sink board) receptacle engineered for ultra-thin OEM applications. By utilizing a 0.80mm mid-mount design and eliminating redundant SuperSpeed data pins, this connector significantly reduces Z-axis height and PCB footprint while maintaining robust power delivery (up to 3A) and basic USB 2.0 connectivity. Manufactured with a durable stainless steel shell and high-temperature LCP housing, it guarantees an extended lifespan of 10,000 mating cycles. It is the perfect factory-direct solution for portable devices, wearables, and compact industrial equipment where space optimization and cost efficiency are paramount without compromising mechanical reliability.
Application Notes
-
PCB Cutout & SMT Profiling: The 0.80mm mid-mount design requires a precise PCB cutout. Ensure the solder stencil is optimized for the 6 SMT contacts to prevent solder bridging on the condensed pitch.
-
Pin Configuration: This simplified 6-pin layout provides VBUS, GND, and CC/DP/DM pins. It is intended for power delivery (up to 60W at 20V/3A) and baseline USB 2.0 data, not for USB 3.x or DisplayPort Alt Mode.
-
Mechanical Reinforcement: Leverage the 4 through-hole (TH) shell stakes during wave or reflow soldering to ensure maximum peel strength and retention force against frequent cable extractions.
-
CC Pin Implementation: For proper Type-C power negotiation, ensure appropriate pull-down resistors (5.1kΩ) are integrated into the PCBA design on the CC lines.
