Frequently Asked Questions
What are the design advantages of combining RJ45 and USB 3.0 into a single combo jack?
Combining an RJ45 8P8C modular jack and a single-port USB 3.0 Type-A connector into a single vertical assembly reduces panel opening width and board footprint by up to 50% compared to discrete connectors, streamlining I/O panel routing on space-constrained motherboards.
What is the recommended PCB footprint layout for this combo connector?
The footprint requires 21x Ø0.90mm through-holes (routing 8 RJ45 pins, 9 USB 3.0 pins, and 4 LED leads) accompanied by 6x Ø2.30mm shield anchoring and ground holes positioned across an 18.70mm span with standard ±0.05mm positioning tolerances.
How do the materials and shielding structure prevent crosstalk and EMI?
The connector features a dual copper alloy shielding structure with overall nickel plating that isolates the high-frequency 5Gbps USB 3.0 lines from the Ethernet interface. Contacts utilize phosphor bronze with selective gold plating, maintaining contact resistance under 30 mΩ.
What electrical dielectric safety parameters does this hybrid connector fulfill?
The connector is rated for 125 VAC RMS at 1.5A. It delivers a dielectric withstanding voltage of 500V AC RMS for 1 minute and a minimum insulation resistance of 500 MΩ, supporting reliable industrial operation between -25°C and +85°C.
Overview and Application Notes
This integrated stacked combo connector combines an RJ45 8P8C female modular jack with a single-port USB 3.0 Type-A female receptacle, featuring integrated dual LEDs (Left Yellow / Right Green) and right-angle DIP through-hole mounting. Engineered for high-density I/O panels, it merges Gigabit Ethernet communication and 5Gbps SuperSpeed USB data connectivity into a unified footprint, saving vital PCB area on industrial motherboards, edge computers, and embedded networking hardware.
Key Features
- Hybrid I/O Integration: Integrates an 8P8C RJ45 modular jack with a 9-pin USB 3.0 Type-A female port in a single stacked assembly.
- Integrated Status Indication: Pre-assembled Yellow (Left) and Green (Right) LED indicators provide hardware status and network packet monitoring.
- Multi-Polymer Housing System: Molded with UL 94V-0 black PBT for the RJ45 housing/cover and UL 94V-0 blue LCP for the high-speed USB 3.0 interface.
- Dual-Layer Shielding: Stamped copper alloy outer shield with nickel plating provides 360-degree EMI/RFI isolation across both ports.
- Durable Contact Architecture: Phosphor bronze contacts finished with gold-over-nickel plating ensure 750 mating cycles and minimal contact resistance.
- Broad Operating Temperature: Fully rated for industrial operating environments from -25°C to +85°C.
Engineering Specifications & PCB Integration
Designed for through-hole component-side mounting on standard FR-4 circuit boards. The high-density footprint incorporates 21x Ø0.90mm through-holes (covering 8 RJ45 contacts, 9 USB 3.0 signal lines, and 4 LED terminals), complemented by 6x Ø2.30mm shield retention holes holding ±0.05mm positioning tolerances. The 18.70mm center-to-center ground span and multi-point ground pins provide mechanical shear strength against dual-cable insertion strain.
