Application Scenarios
-
Ultra-Thin Consumer Electronics : Leverages the edge-mount profile to sink into the PCB edge, significantly reducing overall device thickness for tablets, portable monitors, and wireless keyboards.
-
Industrial Handhelds : Provides a rugged, 10,000-cycle side-entry charging port that withstands frequent plugging in warehouse environments while delivering up to 5A of fast-charging power.
-
Smart Home Hubs : Offers a cost-effective, high-durability power and basic data interface without the premium cost of full 24-pin SuperSpeed connectors.
-
Medical Diagnostic Equipment : Ensures safe, consistent 100W power delivery for portable patient monitors that require robust through-hole mechanical retention against accidental cable pulls.
Frequently Asked Questions
Why choose a 14-pin USB-C receptacle over a standard 24-pin?
The 14-pin configuration retains the essential pins for Power Delivery (up to 5A) and USB 2.0 data (DP/DN) while removing the complex SuperSpeed pins. This simplifies PCB routing, reduces component cost, and is perfect for devices that don't need high-speed data transfer.
What is the benefit of the side-entry (edge mount) design?
A side-entry, edge mount connector sits within a cutout on the edge of the PCB rather than on top of it. This significantly reduces the above-board height (Z-axis profile), making it essential for designing ultra-thin products.
Does this receptacle support USB Power Delivery (PD) fast charging?
Yes. It is rated for 5.0A on the VBUS pins. When paired with the correct CC pin circuitry on your PCBA, it can safely support standard PD profiles up to 100W (20V/5A).
Can you provide 3D step files for this edge mount connector?
Absolutely. We provide comprehensive 2D CAD drawings and 3D STEP files to help your engineering team with enclosure design and PCB cutout clearance checks. Contact us to request the files.
What is the minimum order quantity (MOQ) and lead time?
As a factory-direct OEM provider, standard lead times are typically 2 to 4 weeks. Please submit an RFQ with your projected annual usage to receive specific MOQ details and tiered B2B pricing.
Overview and Application Notes
-
Overview: The EU14FB3M1264 is a 14-pin USB Type-C side-entry (edge mount) female receptacle engineered for space-constrained OEM applications requiring low-profile PCB edge mounting. Featuring a full through-hole (DIP) contact pin configuration (14-pin) paired with 4 DIP outer shell grounding legs, it delivers high mechanical peel strength and vibration resistance. Rated for 5V AC and 5.0A minimum on VBUS lines, it supports standard USB 2.0 (DP1/DN1, DP2/DN2) signal transmission and reliable power delivery. Built with a high-temperature LCP (UL 94V-0) housing, gold-plated copper alloy contacts, and nickel-plated stainless steel shell and mid plate, it ensures 10,000 mating cycles of durable performance in compact edge-mount assemblies.

Application Notes:
-
PCB Edge Cutout & DIP Pin Layout: Adhere strictly to the recommended PCB edge cutout and the 14-pin through-hole footprint (14X dia 0.60mm) and 4-shell DIP anchor slots as defined in drawing EU14FB3M1264 to ensure correct seating and flush edge alignment.
-
Mechanical Anchoring & Wave Soldering: The 4 DIP shell legs provide rugged mechanical anchoring against heavy insertion and extraction forces (rated 5N to 20N insertion, 8N to 20N extraction). Fully fill the through-hole barrels with solder during wave or selective soldering to maximize joint strength.
-
Pin Assignment & Reversibility: This 14-pin receptacle includes dedicated VBUS (5A), GND, CC1/CC2, and dual USB 2.0 differential pairs (DP1/DN1, DP2/DN2) for reversible orientation. It does not support USB 3.x SuperSpeed differential lines.
-
Shield Grounding & Chassis Clearances: Solder all outer shell DIP tabs directly to the system ground plane to provide continuous EMI/RFI shielding and prevent mechanical strain on internal signal contacts during repeated mating cycles.
