Molex 43645-0200 Micro-Fit 3.0 2-Pin Receptacle Housing
Couldn't load pickup availability
Molex 43645-0200 / 0436450200 is a genuine Micro-Fit 3.0 two-position, single-row receptacle housing for compact, latching wire-to-wire and wire-to-board harnesses. It uses the 3.00 mm Micro-Fit pitch in black low-halogen nylon, making it a better fit than loose Dupont-style housings where a printer harness needs a positive latch.
Why use Micro-Fit 3.0 here?
- Positive latch and polarization: the housing locks to the mating Micro-Fit part and is polarized to reduce mis-mating.
- Compact power/signal format: 3.00 mm pitch keeps harnesses smaller than larger Mini-Fit-style connectors while staying more robust than hobby jumper housings.
- Known Molex ecosystem: this is part of the Micro-Fit 3.0 43645 receptacle-housing family, so it belongs with the matching Molex terminals and mating housings instead of mystery clone parts.

Printer and harness fitment
Use this when your BOM calls for a 2-position Molex Micro-Fit 3.0 receptacle housing for a compact 3D-printer wiring harness, toolhead lead, fan/power lead, or electronics-bay connector. It is the plastic housing only; crimp terminals and the mating side are selected separately to match your wire gauge and board or plug.
Nearby live Micro-Fit options in the catalog include the dual-row 2-pin Micro-Fit housing, the dual-row 4-circuit Micro-Fit plug housing, and the Micro-Fit dual-row 4-circuit kit.
What you get
- One genuine Molex 43645-0200 / 0436450200 Micro-Fit 3.0 receptacle housing.
- Loose housing only — no contacts, pre-crimped leads, mating plug/header, or crimp tool included.
Gotchas
- Housing only: you still need the correct Micro-Fit crimp terminals for your wire gauge.
- Single-row 2-circuit: do not substitute this for the dual-row 2-pin housing unless your BOM explicitly allows that change.
- Not interchangeable with Mini-Fit Jr., JST-XH, or Dupont: match the Micro-Fit 3.0 family on both sides before crimping a harness.

Shipping:
US Shipping is via UPS or USPS. The way it is set up shows the least expensive options for standard, priority and express shipping. I can not take special requests for specific carriers at this time.
International shipping is mostly UPS, as I utilize Zonos/UPS integration to tally extremely accurate import and shipping costs.
I require a telephone and email with international orders and you must make yourself available to the carrier or your customs, should they require more information. If you are unreachable and the package is discarded or rerturned, I will not be responsible for rerturning your shipping cost.
If there is a problem with an international order, it is my choice to refund part or all of the order, or send a replacement.
Addresses are verified through Shopify, but the customer is still responsible for inputting their address in the correct format. Any returns or lost shipments, due to incorrectly addressed packages, are the responsibility of the customer.
