The Molex 172952-1801 is an 18-circuit receptacle housing from the Micro-Fit 3.0 172952 series, designed as the wire-side half of a wire-to-board power interconnect.
Crimp Termination and Terminal Selection
The Micro-Fit 3.0 system uses a specific crimp terminal; the 18-position housing accepts the standard Micro-Fit 3.0 female crimp contact. The TPA (Terminal Position Assurance) feature in the housing name means a secondary retainer locks each terminal in place after insertion, confirming full seating before the connector is mated. For harness builders, this eliminates the guesswork on whether a terminal is fully home.
Pitch, Rows, and Board Footprint Match
The 0.118" (3.00 mm) pitch and 0.118" (3.00 mm) row spacing define the footprint this receptacle mates to on the header side. With two rows and 18 positions, the header footprint occupies a 9-position-per-row layout.
