RJ45 Tab Up Connector for Ethernet PCB Jack Applications JU112103DPA0（Cross out ABRACON ARJM11C7-502-AB-ER2-T）

Product Overview

The JU112103DPA0 is a shielded RJ45 tab up connector for through hole ethernet ports. It uses a PBT UL94V-0 black housing, phosphor bronze contacts with gold plating and a 0.20 mm nickel plated C2680 brass shield. Its 8 pin pass through layout links the PHY side to the cable side without magnetics.

Product Specifications

Product Features

• Tab Up Latching
  The tab up orientation keeps the plug release latch above the port for panel and wall mounted layouts.
• Shielded LED Free Housing
  A 0.20 mm nickel plated C2680 brass shield reduces EMI while omitting LEDs for cost sensitive designs.
• 8 Pin Pass Through
  Direct PHY to cable side routing eliminates onboard magnetics for discrete transformer designs.
• Gold Plated Contacts
  Phosphor bronze terminals with 0.35 mm stock and gold contact plating hold 30 milliohm resistance.
• Proven Durability
  Rated for 750 mating cycles minimum across -40C to +85C operation.

Packing Details

• Packaging Method: Standard tray pack with part number traceability on each box
• Carton Quantity: Follows standard VITALCONN packing
• Custom Packaging: Available on request

Applications

• Gigabit and Fast Ethernet Ports
  For discrete magnetics designs that route PHY signals straight to the cable side.
• Set-Top Boxes and Modems
  Suits cost sensitive LED free port requirements in consumer CPE.
• Industrial Control Boards
  The nickel plated shield maintains signal integrity near motors and drives.
• Security and Access Panels
  Tab up latching keeps plugs secure where ports face downward mounting.
• Networking Adapters
  Through hole pins support reliable wave soldering in mid volume production.

Frequently Asked Questions (FAQ)

Q: What is a RJ45 tab up connector used for?
A: An RJ45 tab up connector mounts on a PCB so the plug release latch faces upward after assembly. JU112103DPA0 suits panel mounted ports, wall plates and equipment where the port above would block a downward latch. The shielded 10P8C body routes eight pins straight through without magnetics.

Q: What are the benefits of a shielded LED free RJ45 jack?
A: Removing LEDs lowers component cost and PCB routing complexity, while the 0.20 mm nickel plated C2680 brass shield still diverts EMI and provides a chassis ground path. The jack keeps 1.5A rating, 1000 VAC RMS dielectric strength and 500 megaohm insulation resistance for dependable ethernet links.

Q: What mounting method does JU112103DPA0 use?
A: The connector mounts through hole on a 12.70 x 16.26 mm PCB layout. Its 16.50 x 13.50 x 15.75 mm body accepts standard 8P8C plugs, and phosphor bronze contacts with gold plating are rated for 750 mating cycles minimum from -40C to +85C.
