1x4 RJ45 Tab Down Jack Modular Jack Connector JD144101DPA0（Cross out Molex 441500012）

Product Overview

The JD144101DPA0 is a quad port 1x4 RJ45 tab down jack with an integrated 1000BASE-T magnetics filter. Four stacked shielded 10P8C ports fit in a 13.97 x 21.15 x 59.00 mm body for high density modular jack RJ45 designs. Through hole pins land on a 53.54 x 25.40 mm PCB layout at 1.27 mm pitch.

Product Specifications

Product Features

• Quad Port Density Four stacked ports share one 53.54 mm footprint to multiply available port counts.
• Tab Down Latching Latches sit below the plug body, ideal for vertically stacked rack layouts.
• Integrated Magnetics The 1000BASE-T filter links the cable side and PHY side directly on board.
• Brass C2680 Shield A 0.20 mm nickel plated shield suppresses EMI between adjacent ports.
• Proven Durability Phosphor bronze gold flash contacts are rated for 750 mating cycles minimum.

Packing Details

Supplied in standard trays with part number traceability on each box. Tray pack and carton quantity follow standard VITALCONN packing; custom labeling and packaging options are available on request.

Applications

• Multi Port Ethernet Switches Four ports per connector cut assembly steps and board space.
• Network Attached Storage Gigabit magnetics support high throughput file transfer.
• Industrial Gateways Shielded tab down jacks resist EMI on factory floors.
• Security Video Recorders Stacked 1000BASE-T ports handle multiple IP camera streams.
• Telecom Equipment Through hole mounting withstands vibration and handling.

Frequently Asked Questions (FAQ)

Q: How many ports does a 1x4 RJ45 tab down jack support?
A: The JD144101DPA0 provides four independent 10P8C ports in one vertically stacked body. Each port integrates its own 1000BASE-T magnetics filter, so one 53.54 x 25.40 mm PCB footprint replaces four discrete jack and transformer pairs, cutting placement count and solder joints.

Q: What is the difference between tab up and tab down jacks?
A: The difference is latch orientation. On a tab down jack the plug release tab faces downward after mounting, which suits ports stacked above one another in a chassis. On a tab up jack the latch faces upward. Choose tab down when a port above would block an upward facing latch.

Q: Is the JD144101DPA0 suitable for industrial environments?
A: Yes. The housing is UL94V-0 rated PBT, the brass C2680 shield is nickel plated over all areas, and contacts carry 1.5A with 100 milliohm maximum initial contact resistance. The jack operates from -40C to +85C and withstands 750 mating cycles, covering most industrial networking needs.
