Frequently Asked Questions
Is this 6-pin USB-C receptacle compatible with standard USB-C cables?
Yes. The physical interface conforms to standard Type-C dimensions and is fully intermateable with standard 24-pin and 16-pin USB Type-C cable plugs, while utilizing a 6-pin power-dedicated architecture.
What is the rated mating durability of this connector?
The EU06FB3N11318SR is tested and rated for 3,000 mating cycles, providing a cost-effective and dependable lifespan for consumer charging ports and smart hardware.
Does this connector support high-speed data transfer or video output?
No. The 6-pin layout eliminates the high-speed TX/RX data pins to save PCB space and reduce costs. It is engineered specifically for charge-only devices or extremely basic low-speed connectivity.
Are your connectors RoHS compliant and suitable for automated assembly?
Absolutely. All our OEM electronic components are fully RoHS and REACH compliant. This SMT connector features high-temperature plastic suitable for reflow soldering and is available in Tape & Reel packaging for high-speed automated pick-and-place manufacturing.
What is the standard lead time and MOQ for factory-direct orders?
Standard manufacturing lead times range from 2 to 4 weeks depending on the production volume. Please submit a request for a quote (RFQ) with your target volume for specific Minimum Order Quantities (MOQ) and tier pricing.
Overview and Application Notes
-
Overview: The EU06FB3N11318SR is a compact, 6-pin USB Type-C surface-mount (SMT) female receptacle engineered specifically for power-dedicated and fast-charging OEM applications. By omitting redundant USB data lines, this top-mount connector offers a streamlined PCB footprint while supporting a robust 5.0A current rating and 20V DC power delivery (up to 100W USB Power Delivery). Built with a high-temperature thermoplastic (UL 94V-0) housing, copper alloy contacts with gold flash plating, and a durable nickel-plated front shell with internal grounding stakes, it is rated for 3,000 mating cycles and operates reliably from -30°C to +80°C. It serves as a cost-effective, factory-direct connectivity solution for modern consumer electronics and smart hardware requiring dedicated Type-C power input.

Application Notes:
-
SMT Solder Profile & Reflow Soldering: The high-temperature plastic housing withstands standard IR reflow soldering. Maintain peak board temperature at 260°C for a maximum of 10 seconds.
-
PCB Layout & Inner Shell Stakes: Incorporate the inner shell grounding through-hole slots on the PCB layout according to drawing EU06FB3N11318SR to ensure solid mechanical retention and absorb insertion stress away from SMT solder pads.
-
Power-Only (Charging) Pin Configuration: The 6-pin layout comprises VBUS (5A), GND, and CC1/CC2 channels. It is designed exclusively for power supply and charging negotiations and does not support USB 2.0 (D+/D-) or USB 3.x data transfer.
-
Coplanarity & Stencil Design: Ensure uniform solder paste deposition across all 6 contact pads and grounding pads (maintaining a 0.08mm max coplanarity allowance) to prevent solder bridging or open joints.
