Product details

The TE Connectivity 1705951-1 is an 8p8c (RJ45, Ethernet) modular jack rated Cat3, built for 10BASE-T Ethernet and analog telephony applications where the signal path doesn't need Cat5e bandwidth. The board lock holds it steady through wave solder and resists the plug insertion force that can walk a plain through-hole jack out of alignment.

Cat3 certification limits this jack to 16 MHz signal bandwidth — fine for 10BASE-T Ethernet and POTS phone lines, but it won't pass 100BASE-TX or gigabit Ethernet. The unshielded construction means no EMI gasket or metal shell to bleed interference, so keep it inside a shielded enclosure if the environment has motor drives or switching supplies nearby.

Frequently asked questions

Is 1705951-1 shielded or unshielded?

It's unshielded — no metal shell or EMI gasket. For environments with electrical noise, pair it with a shielded enclosure or choose a shielded RJ45 jack.

What is the pinout of 1705951-1?

The 1705951-1 is an 8p8c (RJ45) jack, so the pinout follows the standard T568A or T568B wiring schemes for Ethernet. The contacts are arranged in a single row of 8 positions. Refer to the manufacturer's datasheet for the exact PCB footprint and pin numbering.
