0820-1X1T-00-F RJ45 USB Combo Connector Overview

The Bel Fuse 0862-1J1T-46A-F is a patented 3-in-1 hybrid I/O Integrated Connector Module (ICM) combining a single-port 1000BASE-T (Gigabit Ethernet) RJ45 MagJack and two stacked USB 2.0 Type-A Female receptacles into a unified vertical through-hole (THT) package.

Crucially designed in a Tab-Up (Latch Up) port orientation, it ensures ergonomic cable latch disengagement without interfering with the lower USB ports. Rated for harsh industrial environments from -40°C to +85°C, it delivers 1500 Vrms dielectric isolation and an ultra-low insertion loss of -1.0 dB Max across all 4 differential pairs. Equipped with 3-wire Bi-Color Orange/Green + Yellow status LEDs (3w-OG/Y).

Key Features

• High-Density 3-in-1: Single-port 1000BASE-T Gigabit RJ45 + Dual USB 2.0 Type-A stacked (saves 65% panel width).
• Tab-Up Latch: Latch-Up design eliminates mechanical interference with lower USB cables.
• 1000BASE-T Magnetics: 4-pair 1CT:1CT transformers with -1.0 dB Max insertion loss and 1500 Vrms isolation.
• Extended Industrial Temp: Rated -40°C to +85°C for harsh outdoor and unconditioned environments.
• Anti-Crosstalk Shielding: Internal grounded metal Faraday barrier delivers -40 dB noise rejection between USB and Ethernet.
• 3-Wire Optical LEDs: Left 3-wire Bi-Color Orange/Green (direct GPIO drive) + Right Yellow LEDs.
• Heavy Gold Plating: RJ45 contacts plated with 30 μ" Hard Gold for high mating durability.
• Certified: UL Recognized (#E196366), RoHS compliant;

RJ45 + Dual USB Combo Architecture Advantages

The 0862-1J1T-46A-F combines three external interfaces in one board-mounted connector assembly:

1. 1 × RJ45 Gigabit Ethernet port + 2 × USB 2.0 Type-A ports

This stacked construction reduces the amount of PCB edge and enclosure-panel space required compared with installing an RJ45 MagJack and two independent USB receptacles.

The architecture is particularly useful where multiple external I/O interfaces must fit into a compact rear or front panel without spreading connectors across a larger motherboard edge.

2. Integrated Gigabit Ethernet Magnetics

Unlike a passive RJ45 receptacle, the 0862-1J1T-46A-F belongs to the MagJack ICM family and integrates Ethernet magnetics into the connector package.

This reduces the need for a separate external LAN transformer between the Ethernet PHY and RJ45 interface.

For production design-in, engineers should still verify the controlled drawing for:

transformer topology, center taps, pin assignment, OCL under DC bias, insertion loss, return loss, common-mode performance and isolation requirements against the selected Ethernet PHY reference design.

3. Industrial Temperature Operation

The -40°C to +85°C operating range makes the 0862-1J1T-46A-F suitable for equipment operating beyond ordinary commercial-temperature environments.

Typical design targets include industrial Ethernet controllers, embedded network appliances, outdoor communication electronics and other systems where the enclosure may experience significant temperature variation.

Temperature rating alone, however, does not establish complete system-level industrial qualification. Vibration, humidity, corrosion, EMC and application-specific environmental requirements should be evaluated separately.

4. EMI Shielding

The connector uses a shielded construction with EMI spring/tab features.

When integrated into a conductive enclosure, the shield geometry can help provide a controlled chassis interface around the RJ45 and USB connector assembly.

Mechanical designers should verify the actual panel opening, shield-tab position and chassis contact geometry using the manufacturer's drawing rather than deriving the cutout from nominal body dimensions.

5. LED Configuration

The 0862-1J1T-46A-F is supplied with front status LEDs using an Orange/Green and Yellow configuration.

For PCB design, LED pin assignments and polarity should be taken directly from the controlled product drawing before layout release.

6. Non-PoE Design

The 0862-1J1T-46A-F is classified as a Non-PoE MagJack.

It should not be promoted as an IEEE 802.3af, 802.3at or 802.3bt PoE connector unless a separate approved variant is specified for the required power application.

100% Pre-Shipment Quality Testing

1. RoHS Analyzer Screening: XRF spectrometer verifies that the copper alloy shield, phosphor bronze contacts, and PBT body strictly comply with RoHS and REACH directives.
2. EMI Shield Ground Continuity Test: Verifies dynamic contact resistance of all grounding tabs to guarantee effective chassis grounding.
3. 1500 Vrms HiPot Dielectric Testing: 100% production screened between Ethernet PHY pins and RJ45 cable contacts.
4. Auto Transformer Analyzer for Gigabit 4-Pair: 100% automated verification of 1CT:1CT (±2%) turns ratios across all 4 channels, ≥350 μH OCL at 8 mA DC bias across -40°C to +85°C, and return loss compliance up to 100 MHz.
5. Dual USB Contact & Continuity Test: Automated pin-to-pin open/short testing across both USB ports with contact resistance verified below 25 mΩ.
6. 3-Wire LED Optical Screening: Automated optical testing verifying forward voltage and distinct illumination for Green (Pin 9), Orange (Pin 10), and Yellow (Pin 8).

Frequently Asked Questions

Q1: What makes Bel Fuse 0862-1J1T-46A-F unique compared to standard RJ45 USB combo jacks?

The 0862-1J1T-46A-F is an advanced 1000BASE-T (Gigabit) combo jack featuring Dual USB 2.0 ports, a Tab-Down (Latch Down) orientation, an extended -40°C to +85°C industrial temperature range, and 3-wire Bi-Color Orange/Green + Yellow LEDs. Most standard combo jacks only support 10/100M speeds, 0°C to 70°C commercial temperatures, or single USB ports.

Q2: What is the benefit of the 3-wire Bi-color LED (3w-OG) in this connector?

A 3-wire bi-color LED provides a common cathode (or anode) terminal with dedicated pins for the Orange and Green emitters. This allows two standard micro-controller GPIO pins to switch between Green, Orange, or Off without requiring an H-bridge or complex bidirectional polarity-switching circuitry.

Q3: Does 0862-1J1T-46A-F support Power over Ethernet (PoE)?

No. It is a Non-PoE Gigabit combo connector. The internal magnetics are dedicated purely to high-speed Fast/Gigabit Ethernet data transmission, while the two USB 2.0 ports supply standard 5V USB bus power (up to 1.5 A per port).
