TE Connectivity 171662-1 Female Receptacle Terminal | Econoseal J Mark II+

The Component: Genuine TE Connectivity / AMP automotive female receptacle crimp socket terminal. Econoseal J Mark II (+) Series taxonomy / 1.8mm contact system / Tin-plated brass construction (F-Crimp / Sealed-Application Grade / Component Alias Code: 171662-1 / Global Order Reference: 171662-1).

Applications & Fitment: Engineered as a mission-critical electrical contact designed for high-vibration, waterproof automotive wiring harnesses. This terminal is the foundational female contact for the Econoseal J Mark II (+) interconnect ecosystem, widely specified across OEM Japanese passenger vehicle platforms and heavy-duty aftermarket engine sensors. It is specifically designed to facilitate secure wire-to-device and wire-to-wire connections within high-exposure zones like engine bays, transmission controllers, and external sensor modules. The design utilizes a precision tin-plated finish to provide superior corrosion resistance and consistent conductivity for low-voltage signal tracks. When used in conjunction with a single-wire seal (SWS), it maintains a rigorous environmental barrier against moisture, engine oil, and chemical vapor. Highly vulnerable to improper terminal retention or intermittent connectivity if crimped using non-standard generic pliers; strictly requires a calibrated OEM-specification ratcheting crimp tool to ensure the proper "F-crimp" geometry and terminal lance engagement within the housing.
