Product details

The TE Connectivity 5554990-1 is a 6P6C modular jack — the 6-position, 6-contact variant that covers RJ11, RJ12, RJ14, and RJ25 wiring schemes. It mounts vertically through a PCB hole and terminates by wave solder. The jack is unshielded and rated Cat3, which limits it to voice-frequency and 10BASE-T Ethernet applications; it is not designed for 100BASE-TX or gigabit data paths.

Board Lock and Mechanical Retention

The tab direction is user-selectable, so the latch orientation can be flipped to match the panel cutout or PCB layout.

No official cross-reference or second-source part is listed for this TE Connectivity modular jack.

Frequently asked questions

Where can I buy the TE Connectivity 5554990-1 modular jack?

The 5554990-1 is sourced to order through independent distribution. Submit an RFQ for current pricing and availability — stock and lead time are confirmed at quote time.

What is the difference between 6P6C and 6P4C?

6P6C has six contact positions with all six loaded, supporting RJ11 (2-wire), RJ12 (6-wire), RJ14 (4-wire), and RJ25 (6-wire) configurations. 6P4C has six positions but only four contacts loaded, which omits the outer two positions and limits compatibility to RJ11 and RJ14 only.

Is 5554990-1 RoHS compliant?

Yes, the 5554990-1 is ROHS3 Compliant.
