Molex Mini-Fit Jr. 4.2mm Single-Head Pre-Crimped Terminal Cable — 18AWG UL1007 PVC, 9A / 600V
The Molex Mini-Fit Jr. 4.2mm single-head pre-crimped terminal cable is engineered for professional high-current power harness assembly. With a bare male crimp terminal on one end and a bare tinned lead on the other — without a housing — it is designed for applications where the Mini-Fit Jr. plug housing is already installed, and the opposite end is soldered directly to a PCB pad, bus bar, or screw terminal.
Rated at 9A per contact and 600V with an 18AWG UL1007 PVC conductor, this cable is the standard choice for ATX power supply fabrication, industrial motor drive wiring, server power distribution, and automotive high-current harness assembly.
Key Features
- Genuine Molex Mini-Fit Jr. male crimp terminal — precision-stamped contact for reliable, low-resistance connections in Mini-Fit Jr. plug housings (Molex 45111 / 5559 series)
- Single-head configuration — male terminal one end, bare tinned lead other end
- 18AWG UL1007 PVC insulation — rated 80°C, 300V, flexible and durable
- 9A / 600V rating — handles high-current power lines in ATX, industrial, and automotive applications
- Pre-crimped factory assembly — consistent, reliable crimp quality
- RoHS compliant
Typical Applications
- ATX power supply custom cable fabrication (24-pin, 8-pin EPS, PCIe)
- Industrial motor drive and inverter power harness assembly
- Server and data center rack power distribution
- Automotive battery and high-current circuit wiring
- Custom PCB power connector population

Frequently Asked Questions
Product & Compatibility
What is the difference between JST PH, XH, ZH, and SH connectors?
JST connectors differ primarily in pitch (pin spacing): SH = 1.0mm, ZH = 1.5mm, PH = 2.0mm, XH = 2.5mm. Smaller pitch connectors are used in compact electronics like drones and wearables, while larger pitch connectors suit general prototyping and power applications. Always verify pitch before ordering to ensure compatibility.
Are your connectors compatible with standard Arduino and Raspberry Pi projects?
Yes. Our DuPont 2.54mm connectors are the industry standard for Arduino, Raspberry Pi, and most development boards. JST PH 2.0mm is widely used for LiPo batteries in RC and robotics projects. We recommend checking your board's datasheet to confirm the exact connector type and pin count required.
What wire gauge (AWG) should I choose for my application?
Wire gauge depends on current load: 28–30 AWG suits signal lines up to 0.5A; 24–26 AWG handles 1–3A for moderate power; 22 AWG is suitable for up to 5A. For high-current applications, always use appropriately rated wire and connectors. Our product listings specify the AWG and rated current for each cable.
What is the difference between UL1007 and Silicone wire?
UL1007 is a PVC-insulated wire rated for 80°C and 300V, suitable for most indoor electronics applications. Silicone wire is rated for higher temperatures (up to 200°C), is more flexible, and performs better in harsh environments or high-vibration applications such as RC vehicles and industrial equipment.
Orders & Customization
Can I order custom cable lengths or connector configurations?
Yes. We offer custom wire harness solutions including custom lengths, connector types, pin counts, and wire colors. Please contact us via the Contact page with your specifications and we will provide a quote within 1–2 business days.
Do you offer bulk or wholesale pricing?
Yes. Volume discounts are available for orders of 50 units or more. Please reach out through our Contact page with your requirements for a customized wholesale quote.
How do I know which connector polarity or pin orientation to order?
Always refer to your device's datasheet or existing connector for pin 1 orientation. Our product images include wiring diagrams where applicable. If you are unsure, contact us with your device model and we will help identify the correct part.
Shipping & Returns
How long does shipping take?
Standard international shipping typically takes 7–15 business days depending on destination. Expedited options are available at checkout. Orders are processed within 3 business days. Tracking information is provided via email once your order has shipped.
