The free-hanging (in-line) mounting style and solder termination mean it terminates to a cable assembly, not a PCB. The white insulation colour is standard for TE's micro A plugs. Rated for 30V and a multi-amp current profile — 0.5A, 1A, and 1.8A per contact — the 1.8A leg covers the VBUS power pin, while the signal pins run at the lower ratings. ## Sourcing This Obsolete Part The 1939053-1 is officially marked Obsolete by TE Connectivity. There is no listed direct replacement or successor order code in the TE portfolio. ## What Crosses Into the Harness You've Got It is not compatible with USB 3.0 — the 1939053-1 is a USB 2.0 (480 Mbps) part, so the pinout and signal integrity stop at that spec. If the existing harness uses a micro B plug, this micro A will not fit the receptacle; the two form factors are keyed differently. The 5-contact count and 30V rating are standard for the micro A interface, so any micro A receptacle from another manufacturer that follows the USB 2.0 pinout will mate electrically.","metaTitle":"TE Connectivity 1939053-1 USB micro A Plug, 5 Contacts, 30V","metaDescription":"TE Connectivity 1939053-1 USB micro A plug, 5 contacts, gold plating, rated 30V.
