16-Position Micro-Fit+ Plug Housing for Crimp-Terminated Harnesses
The Molex 2159221601 is a 16-circuit plug housing from the Micro-Fit+ 215922 series.
Locking Ramp and Dual-Row Layout
The housing uses a locking ramp fastening type — the ramp engages with the matching receptacle's latch for a positive, vibration-resistant mate. The dual-row arrangement (2 rows × 8 positions) distributes the 16 circuits across a 3.00mm row spacing, which keeps the connector width manageable for multi-wire harness breakouts.
Material and Environmental Range
The black color is standard for the Micro-Fit+ line and aids visual identification on the assembly line.
Terminal Compatibility and Crimp Termination
This plug housing accepts male crimp terminals from the Micro-Fit+ family — the 43030 series pins (e.g., 430300001 for 20-24 AWG, tin-plated) and the 43031 series for higher-cycle gold-plated applications. The crimp termination requires the Molex hand crimp tool (part of the 63811 series) or a bench press with the appropriate applicator die. Section a sample crimp to verify strand capture: the terminal's crimp height window is published in the terminal datasheet, and the PA66 housing provides the dielectric retention for the inserted pin.
