Overview

The TE Connectivity 1903120-1 Tab Contact (SKU: 1903120-1) is a crimp-style electrical connector designed for reliable signal applications in industrial, commercial, and automotive systems. Constructed from a durable copper alloy with tin plating, this tab contact delivers consistent electrical conductivity while resisting corrosion in harsh environments. The component is rated for 250 VAC and 250 VDC, making it suitable for both power and low-voltage signal applications. It accommodates discrete wire sizes from 28 to 22 AWG (0.08 to 0.38 mm²), providing versatility for compact and mid-sized wiring harnesses. The crimp termination ensures a secure mechanical and electrical bond, minimizing signal loss and contact resistance over time. Operating within a temperature range of -55°C to 105°C (-67°F to 221°F), the 1903120-1 is engineered for dynamic applications where vibration, thermal cycling, or mechanical stress are present. Part of the Dynamic 1000 Series, this tab contact is ideal for use in control panels, instrumentation, telecommunications equipment, and automotive electronics where dependable signal integrity is critical. The UNSPSC code 39121522 classifies this product as a discrete wire electrical contact, confirming its compatibility with industry-standard crimp tools and wire termination practices. Manufactured in the USA, the 1903120-1 meets stringent quality and reliability standards for global industrial applications.
