Interchangeable part numbers for this profile. A solid node is already profiled in this catalogue; a hollow node is a valid substitute that has no profile yet.
-
RJHSE-5381 not yet profiled
Same jack with the LED colours swapped and a different internal magnetics option. Nearly identical part number and a completely different BOM line — read the ordering code rather than assuming the last digit is a revision.
-
7499111121A not yet profiled
Wurth RJ45 jack with integrated magnetics for 10/100 Ethernet. Adds isolation and impedance matching on-die, removing four discrete transformers from the board; costs about 2.5x the plain jack.
-
5557786-1 not yet profiled
TE Connectivity 8P8C jack without shielding or LEDs. Cheaper and simpler; use it where the link is short and low-speed and no indicator is needed. Not a drop-in — the shield tabs are the mounting structure on the shielded part.
Selection notes
The only prose on this page
1.5 A per contact is for PoE, and it is not enough
A plain RJ45 contact is rated 1.5 A, but IEEE 802.3at Type 2 PoE pushes 600 mA per pair over two pairs, which is 300 mA per contact — comfortably inside the rating. Type 3 and Type 4 (up to 90 W) use all four pairs and run at higher current with a correspondingly higher temperature rise; jacks intended for that service specify a higher current rating and are a different part number.
Integrated magnetics versus discrete
A jack with integrated magnetics removes four discrete transformers and their termination network, saving roughly 400 mm² of board and 12 components. The trade is that the magnetics are now a single point of failure and a single source, and a magnetics-equipped jack costs 2-3x a plain one. For low-volume designs the discrete transformers are usually cheaper and easier to second-source.
Shield grounding and the chassis question
The metal shield should normally be tied to the board's ground plane through the mounting tabs, and optionally to chassis ground through a 1 nF capacitor in parallel with a 1 MΩ resistor. Connecting the shield directly to chassis on a board that also has a signal ground creates a ground loop that shows up as a 50 Hz hum on an analogue input sharing the same board.

| Sourcing — Availability risk | RJ45 jacks are made by Amphenol, TE, Molex, Wurth, Bel and many Asian suppliers. Because the part is large and mechanical, inventory is measured in weeks rather than months of demand; a stockout is unlikely but a specific LED colour or magnetics combination can have a 10-12 week lead time. |
|---|---|
| Pinout and handling | Eight contacts numbered 1 to 8 from the left when looking into the jack with the latch down (T568B order: white-orange, orange, white-green, blue, white-blue, green, white-brown, brown). The shield tabs and the two LED pins are separate from the signal contacts and must be terminated separately; leaving the shield tabs unsoldered removes the mechanical retention as well as the shielding. |
