Application Scenarios
-
Industrial Panel PCs & HMIs: Utilizes the mid-mount design to drastically reduce the vertical profile of the motherboard, enabling ultra-slim touchscreen enclosures without sacrificing physical durability on the factory floor.
-
Medical Diagnostic Equipment: Provides highly reliable, high-speed 5 Gbps data connections essential for portable imaging carts and patient monitoring systems.
-
Test & Measurement Devices: Delivers a rugged, through-hole anchored diagnostic interface capable of withstanding repeated plug-ins and lateral stress from field technicians.
-
Embedded Computing & Thin Clients: Solves space constraints in compact mini-PCs by sinking the connector directly into the PCB cutout, maximizing internal layout efficiency and airflow.
Frequently Asked Questions
What is the standard Minimum Order Quantity (MOQ) for this USB 3.0 mid-mount receptacle?
Our standard MOQ for tape-and-reel or tray packaging is typically 1,000 to 3,000 pieces per batch for volume production. However, we offer flexible prototype quantities for engineering validation and NPI builds.
Can the gold plating thickness on the contacts be customized?
Yes. While Gold Flash is our standard offering, we can customize the plating thickness up to 15μ" or 30μ" gold over nickel to meet strict military or harsh-environment industrial specifications upon request.
Is this connector a functional replacement for major brands like TE or Amphenol?
The EU09F2L3N12343SR features an industry-standard mid-mount footprint, making it a cost-effective, drop-in alternative for many tier-1 brand part numbers. We highly encourage requesting 3D CAD models (STEP/IGES) to verify your PCB cutout tolerances.
Are the thermoplastic housings compatible with reflow soldering?
This specific part is designed with DIP through-hole pins optimized for wave soldering. If your automated assembly process requires Pin-in-Paste (intrusive reflow), we can manufacture the insulator using specialized LCP plastics. Please specify this during your RFQ.
What are the typical lead times for bulk OEM production?
Standard factory lead times range between 2 to 4 weeks, depending on order volume and raw material availability. Expedited production schedules can be arranged for critical OEM projects.

Overview: The EU09F2L3N12343SR is an industrial-grade USB 3.0 Type-A female receptacle engineered with a space-saving mid-mount (sink-board) architecture. Featuring a 90-degree right-angle through-hole (DIP) contact design, dual locating pegs, and heavy-duty outer shell stakes, it delivers superior mechanical retention against rugged mating and unmating forces (rated 35N max insertion, 8N min extraction). Supporting SuperSpeed 5 Gbps data transmission with a 1.5A contact current rating at 30V AC/DC, this connector is constructed with a high-temperature UL94V-0 blue LCP housing, gold/tin-plated copper alloy contacts, and a nickel-plated SUS201 stainless steel shell. Rated for 1,500 mating cycles and operating reliably from -40°C to +85°C, it is an ideal solution for low-profile industrial PCs, embedded motherboards, and rugged diagnostic equipment.

Application Notes:
-
PCB Cutout & Mid-Mount Alignment: The mid-mount design drops the connector profile into a PCB cutout. Strictly follow the recommended PCB cutout and footprint on drawing EU09F2L3N12343SR. Recommended PCB thickness is 1.0mm to 1.2mm.
-
Through-Hole Soldering Process: The 9-pin DIP contact layout and dual shell stakes are optimized for standard wave soldering. Maintain proper temperature controls to protect the UL94V-0 LCP insulator.
-
SuperSpeed Signal Integrity: Route the USB 3.0 differential pairs (SSTX/SSRX) with a strict 90-ohm differential impedance directly to the contact solder pads to maintain 5 Gbps performance.
-
Shell Grounding & EMI Shielding: Solder the SUS201 stainless steel through-hole shell tabs completely to the system ground plane to ensure effective EMI/RFI shielding and absorb user mating torque.
