Frequently Asked Questions
Does this Type-C receptacle support USB Power Delivery (PD) 3.1 Extended Power Range (EPR)?
Yes. It is rated for 48V DC and 5A, fully supporting the 240W EPR standard required for high-power devices, modern laptops, and industrial equipment.
Is the EU24FB3N11249X a drop-in replacement for mainstream brands?
This mid-mount connector features a standard industry footprint. In many cases, it acts as a drop-in replacement for equivalent TE Connectivity or Molex parts. We recommend requesting our CAD drawings and 3D step files for engineering review.
What is the packaging method for high-volume SMT assembly?
For automated pick-and-place machines, these receptacles are supplied in standard Tape and Reel packaging.
Can EDOM Electronics provide custom cable assemblies mating with this receptacle?
Absolutely. As an OEM/ODM factory, we manufacture end-to-end solutions, including custom overmolded Type-C cable assemblies that mate perfectly with this receptacle.
What is the standard lead time and Minimum Order Quantity (MOQ)?
For standard configurations, our MOQ is typically one full reel (varies by exact packaging size). Lead times run between 2 to 4 weeks depending on current factory capacity and raw material availability.
Overview and Application Notes
Overview: Engineered for ultra-thin consumer electronics and robust industrial applications, the EU24FB3N11249X is a premium 24-pin USB 3.2 Gen2 Type-C receptacle. This mid-mount, surface-mount (SMT) connector delivers blazing-fast 10 Gbps data transfer rates alongside cutting-edge 240W (48V/5A) Extended Power Range (EPR) capabilities. Manufactured under strict quality controls, it guarantees up to 10,000 mating cycles for exceptional durability. As a direct factory-backed solution, EDOM Electronics offers flexible OEM/ODM customization, ensuring seamless integration into your specific PCB layouts and volume manufacturing processes.
Application Notes:
-
PCB Cutout & Low-Profile Design: Requires a precise PCB cutout for the mid-mount installation, significantly reducing the overall vertical profile of the host device.
-
Thermal Management for EPR: Operating at 240W (48V/5A) mandates optimized PCB copper pour and trace widths on the VBUS and GND pins to mitigate heat generation.
-
EMI/RFI Shielding: The robust metal shield should be securely grounded to the PCB using the SMT shell stakes to ensure signal integrity at 10 Gbps speeds.
-
SMT Reflow Compatibility: Designed to withstand standard lead-free SMT reflow soldering profiles. Ensure proper solder paste volume for both the 24 signal pads and the structural shell stakes to guarantee mechanical retention.
