The single-row layout keeps the connector narrow, suited for tight spots inside power supplies, appliances, or automotive junction boxes where three power or signal wires need a clean disconnect point. This is a free-hanging (in-line) housing — no PCB footprint needed. It accepts female socket crimp terminals, which are ordered separately (contacts not included). ## Terminal Position Assurance (TPA) Lock The housing includes a Terminal Position Lock (TPA) feature — a secondary retainer that locks each crimped terminal into its cavity after insertion. This prevents back-out under vibration or wire pull, a common failure point in unkeyed housings. The fastening type is a latch holder, meaning the mated pair clicks together with a positive lock and releases by squeezing the latch. No tools needed for mating or unmating in the field. ## Sourcing and Lifecycle Because contacts are not included, the BOM line must also specify the matching female crimp terminal (Molex Micro-Fit 3.0 terminal, e.g. 430300001 for 20-24 AWG). Stock both halves or neither — an orphan housing with no terminals on the shelf is dead stock.","metaTitle":"Molex 1718500300 Micro-Fit 3.0 Receptacle Housing","metaDescription":"Molex 1718500300 Micro-Fit 3.0 receptacle housing, 3 circuits, 3.00mm pitch, TPA lock, crimp termination.
