Frequently Asked Questions
Are compliance certifications like RoHS and REACH available for this connector?
Yes. All our connectors, including the 25.EU18FL2N1234 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.
How does the through-hole mounting design benefit high-vibration applications?
The dual through-hole shell stakes and through-hole signal pins create strong mechanical anchor points on the PCB, providing significantly higher retention force and strain relief compared to surface-mount (SMT) designs.
Can this connector withstand standard wave soldering automated assembly?
Yes. The insulator housing is molded from high-temperature thermoplastic capable of withstanding standard lead-free wave soldering profiles with peak temperatures up to 260°C.
Overview and Application Notes
Overview
The Dual-Port Stacked USB 3.0 Type-A Receptacle (PN: EU18FL2N1234) is an industrial-grade, high-density connector engineered for space-constrained PCB designs requiring dual SuperSpeed USB connectivity. Featuring an 18-pin through-hole configuration (9 pins per port) and robust EMI/RFI shielding, this dual receptacle delivers data transfer speeds up to 5 Gbps while maintaining strict signal integrity. Designed for elevated horizontal top-mount PCB installation, it provides superior mechanical stability and mating durability up to 1,500 cycles. As a factory-direct OEM/ODM provider, EDOM Electronics offers customized contact plating, housing modifications, and rigorous quality testing to meet demanding commercial and industrial standards.
Application Notes
-
Grounding & EMI Control: Ensure all shell solder stakes are fully tied to the system ground plane to provide optimal shielding against electromagnetic interference and high-frequency noise.
-
PCB Layout & Clearance: Maintain recommended solder pad spacing for all 18 contacts to prevent solder bridging during automated wave soldering processes.
-
Mechanical Load Relief: Incorporate adequate panel cutout clearance to prevent physical strain on the PCB solder tails when external cable assemblies are plugged or unplugged.
-
Thermal Profiling: Compatible with standard lead-free wave soldering profiles; verify peak temperature limits (up to 260°C for 5 seconds) to avoid housing deformation.
