Product details

8p8c RJ45 Jack, Cat3, Right-Angle Through-Hole

The TE Connectivity 5557788-1 is an 8p8c (RJ45, Ethernet) jack rated Cat3 — a 16 MHz interface suited for voice-grade telecom and 10BASE-T Ethernet. Unshielded construction keeps the part cost low but means it is not intended for environments where conducted or radiated EMI must be shunted to chassis ground. A board guide aids alignment during through-hole soldering, and the shorting feature on selected positions can be used for loopback or presence detection in the circuit design. The tab faces down when mounted, matching the standard RJ45 plug latch orientation.

Frequently asked questions

Is the 5557788-1 a Cat3 or Cat5e jack?

The 5557788-1 is rated Cat3, not Cat5e. It is designed for 16 MHz applications such as voice and 10BASE-T Ethernet, not for 100BASE-TX or gigabit Ethernet.

Is the 5557788-1 connector shielded?

No, the 5557788-1 is unshielded. It does not include a metal shell or ground termination for EMI bleed, so it is not suited for environments requiring conducted or radiated noise protection.
