The Molex 2147192020 is a 2-circuit header housing from the Zero-Hachi 214719 series, built for fine-pitch wire-to-board interconnects at 0.80 mm pitch.
The friction lock engages when fully seated — no separate clip or screw. The crimp termination accepts non-gendered contacts, which must be ordered separately. The contact part numbers for this series are available in the Molex Zero-Hachi application tooling documentation; typical terminals use a 0.80 mm pitch crimp design.
No second-source or cross-reference is listed in the evidence.
