Product details

What This Jack Does in the Build

It carries a Cat5 rating, meaning it supports 100 MHz signaling typical for 100BASE-TX Ethernet, and the 8-position, 8-contact layout matches standard T568A/B wiring schemes.

Key Features That Affect Assembly and Fit

Zero Insertion Force (ZIF) contacts reduce the force needed to seat the plug, which cuts wear on both the jack and the plug latch over repeated mating cycles — useful for test ports or field-service connections. The integrated board guide helps align the jack during hand-solder or wave-solder assembly, preventing tombstoning or skewed placement. The green/yellow LED indicators provide link/activity status visible through the panel cutout — a common requirement for managed switches and patch panels.

Sourcing This Part

The tray packaging (per the spec) means the jack ships in anti-static trays, not tape-and-reel, so factor that into pick-and-place planning if you are running a high-volume line.

Frequently asked questions

Is 5406508-4 RoHS compliant?

Yes, the 5406508-4 is ROHS3 compliant and carries a lead (Pb)-free finish, so it meets the RoHS exemption requirements for solder termination.

What is the difference between shielded and unshielded RJ45 jacks?

This 5406508-4 is unshielded — it has no metal shield or EMI fingers, so it relies on the system enclosure for noise rejection. A shielded version of the same base number adds a metal shell that grounds to the chassis, which is necessary in plastic enclosures or near switching power supplies.
