Application Scenarios
-
Industrial Panel PCs & HMIs : Utilizes the mid-mount design to drastically reduce the vertical profile of the motherboard, allowing for ultra-slim touchscreen enclosures without sacrificing the mechanical strength required for factory floors.
-
Medical & Diagnostic Carts : Delivers highly reliable, 10,000-cycle high-speed 5 Gbps connections for portable medical imaging devices where physical robustness and data integrity are critical.
-
Embedded Computing & Thin Clients : Solves space constraints in compact mini-PCs by sinking the connector directly into the PCB cutout, maximizing internal airflow and component layout real estate.
-
Test & Measurement Equipment : Provides a highly stable, through-hole anchored diagnostic interface capable of surviving frequent plug-ins from test technicians and external data logging equipment.
Frequently Asked Questions
What is the standard Minimum Order Quantity (MOQ) for this USB 3.0 receptacle?
As an OEM-focused manufacturer, our standard MOQ for tape-and-reel or tray packaging is typically 1,000 to 3,000 pieces per reel/batch. However, we offer flexible prototyping MOQs for engineering evaluation. Contact our sales team to discuss your current project stage.
Can I customize the gold plating thickness on the contacts?
Yes. The standard offering is Gold Flash, but for extreme environments or military-grade requirements, we can provide custom plating options such as 15μ", 30μ", or up to 50μ" gold over nickel upon request.
Is the thermoplastic housing compatible with high-temperature soldering?
The insulator is molded from high-temperature UL94V-0 thermoplastic. While designed primarily for standard wave soldering (DIP), we can supply variations manufactured with specialized LCP plastics compatible with intrusive reflow (Pin-in-Paste) profiles. Please specify this requirement during your RFQ.
Can this connector act as a drop-in replacement for major brands like TE or Molex?
Yes, the EU09FL3N12247 features an industry-standard mid-mount footprint and CH=1.70mm center height, making it a functional drop-in alternative for many equivalent high-priced tier-1 brand part numbers. We highly encourage requesting 3D models (STEP/IGES) to verify PCB cutout tolerances prior to ordering.
What are the typical lead times for bulk production?
Standard factory lead times run between 2 to 4 weeks depending on the material availability and order volume. Expedited production can be arranged for urgent OEM schedules.
Overview and Application Notes
Overview Engineered for low-profile PCB designs, the EU09FL3N12247 is an industrial-grade USB 3.0 Type-A female receptacle featuring a space-saving mid-mount (sink-board) architecture. With a rugged right-angle DIP through-hole design and built-in locating pegs, it ensures superior mechanical stability against high mating forces and PCB stress. Capable of delivering up to 5 Gbps SuperSpeed data transfer and supporting a guaranteed 10,000 mating cycles, this connector is the ultimate choice for OEMs developing durable industrial PCs, automation controllers, and compact commercial electronics. As a factory-direct manufacturer, we offer full customization on contact plating and packaging to meet your specific assembly line requirements.
Application Notes
-
Footprint & Clearance: The mid-mount design requires a specific PCB cutout (CH=1.70mm). Verify the mechanical drawing to ensure adequate clearance for the connector belly and optimal board-level height reduction.
-
Impedance Matching: For reliable 5 Gbps data transmission, ensure that the SuperSpeed differential pairs (SSTX/SSRX) on your PCB are routed with a strict 90-ohm differential impedance.
-
Soldering Guidelines: The through-hole (DIP) shield stakes and contact pins are optimized for standard wave soldering processes. Ensure correct thermal profiling to prevent damage to the UL94V-0 thermoplastic insulator.
-
EMI/RFI Shielding: The metal shell is equipped with grounding tabs. It is highly recommended to connect these directly to the chassis ground plane to minimize electromagnetic interference in noisy industrial environments.
