Dual Port RJ45 Jack with LED 8P8C Connector JD112142TPH1（Cross XMULTIPLE XRJDB-S-02-8-8-4 ）

Product Overview

The JD112142TPH1 is a 1x2 dual port RJ45 modular jack supplied in an 8P8C configuration without magnetics. Contacts are formed from 0.35 mm phosphor bronze with a 50u inch nickel underplate, gold plating on the contact area and a minimum of 100u inch tin on the solder tails. The copper alloy shield, 0.20 mm thick and plated with nickel, grounds to the PCB for EMI control, while the black PBT housing is rated UL94V-0. The jack operates from -40 to +85 Degree C and its cavity geometry conforms to FCC Part 68 Subpart F rules.

Product Specifications

Product Features

• Integrated Status LEDs: Each port carries a green and a yellow LED wired on dedicated pins for link and activity indication without extra board components.
• Gold Plated Contact Area: Phosphor bronze contacts with nickel underplate and gold plating in the contact area keep connection quality stable over repeated mating cycles.
• Nickel Plated Shield: The 0.20 mm copper alloy shield is plated with nickel and grounds through PCB tabs to suppress EMI in dense multi-port layouts.
• UL94V-0 PBT Housing: The black PBT housing meets UL94V-0 flame retardancy for demanding equipment environments.
• FCC Part 68 Cavity Geometry: The jack cavity conforms to FCC rules and regulations Part 68 Subpart F, supporting standard RJ45 plugs on Cat5e and lower category patch cords.

Packing Details

Each JD112142TPH1 is inspected, packed in anti-static bags and sealed in labeled inner boxes before shipment. Standard export cartons with internal cushioning protect the through-hole pins and LED components during transport. Bulk, tray or tube packing can be arranged to suit manual assembly or automatic insertion equipment.

Frequently Asked Questions (FAQ)

Q: Does this dual port RJ45 jack include magnetics?

A: No. The JD112142TPH1 is a passive jack without a transformer, so it must be paired with external magnetics or a PHY that integrates them. Keeping the magnetics off the connector gives designers freedom to place the transformer for optimum layout across both ports.

Q: Which LEDs are built into this RJ45 jack and how are they wired?

A: The left port LED is green, wired between pins L4 positive and L3 negative, and the right port LED is yellow, wired between pins L2 positive and L1 negative. Both LEDs are driven directly from the PHY link and activity outputs through series resistors, so no separate indicator parts are needed on the board.

Q: What plating is used on the contacts and solder tails?

A: The phosphor bronze contacts carry a 50u inch nickel underplate over all areas, gold plating on the contact area and a minimum of 100u inch tin on the solder tails. This combination protects the mating surface, supports wave and hand soldering and keeps the contact interface stable over the -40 to +85 Degree C operating range.
