Custom 2-Pin Molex Mini-Fit Jr. Overmolded Power Cable Assembly (4.20mm Pitch)

  • Connector A: 2-Pin Receptacle (Molex 39-01-2020 / 5557 Series equivalent)

  • Connector B: Custom (Stripped, tinned, or per engineering drawing)

  • Pitch & Terminals: 4.20mm Pitch, using Molex 5556 Series Female Crimp Terminals

  • Design Feature: Precision injection overmolding for superior strain relief and durability

  • Wire Gauge: 16 AWG to 24 AWG UL-certified wire

  • Current Rating: Up to 9.0A per circuit (depending on wire gauge)

  • Applications: PC Power Supplies (ATX), Industrial Automation, Server Motherboards

  • MOQ / Lead Time: Low MOQ, 7–15 days (project-based)

  • Comprehensive In-House Tooling (Molex Multi-Pin Molds): We own an extensive library of precision injection molds for the entire Molex Mini-Fit Jr. (4.20mm) and Micro-Fit families. Whether your project requires 2-pin, 4-pin, 6-pin (PCIe), 8-pin (EPS), 10-pin, 14-pin, or up to 24-pin (ATX) configurations, we can provide heavy-duty overmolded strain relief without passing on new tooling costs to you.

  • Exact Component Specifications: For this 2-Pin assembly, we strictly adhere to the mechanical specifications of the Molex 39-01-2020 (Series 5557-02R) housing, mated with high-conductivity Molex 5556 Series female crimp terminals (e.g., 39-00-0038 or 39-00-0077 for 16AWG). It fully mates with standard 5559 plugs and 5566/5569 headers.

  • Cost-Optimized Equivalents: While we fully support original Molex BOMs, we also offer premium UL-certified equivalent housings and terminals to significantly reduce your procurement costs and bypass long lead times, with zero compromise on mating retention or electrical safety.

  • Overmold Direction: Our overmold tooling supports standard straight exits, as well as 90-degree right/left angled exits for space-constrained chassis routing.

  • Wire Specifications: Customizable wire types (UL1007, UL1015, high-flex silicone) and specific color coding based on your power distribution schematic.
