The TE Connectivity 1903391-1 is a 2-position receptacle housing from the Grace Inertia 2.5 series, designed for wire-to-board or wire-to-wire applications where a positive latch keeps the pair mated under vibration. The 0.098" (2.50mm) pitch keeps the board footprint compact while leaving enough creepage for the voltage rating typical of this class. The housing is natural-colour glass-filled PBT, free-hanging (in-line), and accepts female socket crimp terminals — contacts are ordered separately.
