The Molex 0019091019 is a 1-position receptacle housing from the 3191 series, designed for free-hanging (in-line) wire-to-wire or wire-to-board connections. It uses a latch lock for secure mating and accepts either male or female crimp terminals — but the contacts are not included and must be ordered separately.
Single-Position Receptacle — What It Does and What It Needs
This is a single-circuit housing: one position, one row. It mates with the matching 3191 series plug housing (male pin version) to form a discrete wire pair. The latch lock provides audible and tactile feedback when fully seated — no secondary locking mechanism required for most applications. Because the housing accepts both male and female contacts, you can use it as either the receptacle or the plug side depending on the terminal loaded. The crimp termination means you need a compatible crimp tool and the correct terminal (Molex.093 pin or socket, series 3191) to build the wire assembly.
