Frequently Asked Questions
Are compliance certifications like RoHS and REACH available for this connector?
Yes. All our connectors, including the EU18FL1N1234 dual USB 3.0 receptacle, strictly comply with RoHS 3.0 and REACH environmental standards. Material test reports and compliance certificates are available upon request.
What customization options are available for OEM orders?
As an OEM manufacturer, we offer custom gold plating thicknesses (from Gold Flash up to 30u"), custom pin tail lengths, alternative shell staking options, and modified housing materials to meet high-temperature or specific environmental requirements.
What is the minimum order quantity (MOQ) and typical production lead time?
Our standard MOQ for connector components is 1,000 pieces. Sample prototyping takes approximately 3–5 days, while full volume production lead time typically ranges from 2 to 3 weeks depending on order quantity.
What mounting style and shell configuration does this dual USB 3.0 connector feature?
The EU18FL1N1234 features a 90-degree right-angle through-hole (DIP) mounting style with a flangeless outer shell (without external spring tabs) and 4 heavy-duty shell solder tabs for PCB thicknesses ranging from 1.20mm to 1.60mm.
Can this connector withstand standard wave soldering automated assembly?
Yes. The insulator housing is molded from durable PBT (Thermoplastic) capable of withstanding standard wave soldering profiles. Please refer to standard PBT thermal guidelines to prevent housing deformation during automated assembly.
Overview and Application Notes
-
Overview: The EU18FL1N1234 is an industrial-grade, dual-port stacked USB 3.0 Type-A female receptacle designed for 90-degree right-angle through-hole (DIP) horizontal PCB mounting. Featuring an 18-pin configuration (9 pins per port) with a flangeless (without lead-in spring fingers/tabs) outer shell design, it delivers SuperSpeed data transfer rates up to 5 Gbps while maximizing PCB front-panel space. Constructed with durable UL94V-0 rated thermoplastic (PBT, Pantone 300C blue) insulators, gold-flash and tin-plated copper alloy contacts, and a nickel-plated brass/SPCC shield, this connector operates across an industrial temperature range of -55°C to +105°C with a tested durability of 1,500 mating cycles. It provides a rugged, space-saving I/O solution for industrial computing, networking gateways, and embedded automation systems.
-
Application Notes:
-
PCB Hole Footprint & Thickness: Ensure the PCB layout strictly matches the 18-pin DIP contact layout (18X dia 0.70mm) and 4-shell grounding tabs (4X dia 2.30mm) per drawing EU18FL1N1234. Recommended PCB thickness is 1.20mm to 1.60mm.
-
Shell Grounding & Retention: Fully solder all four brass/SPCC shell DIP legs to the board ground plane to provide continuous EMI/RFI shielding and absorb insertion/withdrawal forces, protecting internal pin solder joints.
-
Flangeless Enclosure Integration: Featuring a clean, flangeless mating face (without outer shell lead-in springs), ensure panel cutout dimensions allow precise clearance and bezel alignment during system assembly.
-
Wave Soldering Parameters: The UL94V-0 PBT insulator is compatible with standard lead-free wave soldering profiles. Control peak temperature exposure to prevent thermal distortion of the dual-stacked housing.
