Molex KK 254 / MX5264 2.54mm Female Both-Sided Pre-Crimped Terminal Cable — 22AWG UL1007 PVC, 3A / 250V
The Molex KK 254 / MX5264 2.54mm female both-sided pre-crimped terminal cable features genuine Molex KK 254 female crimp terminals on both ends — without housings — for direct insertion into KK 254 / MX5264 locking housings or custom connector bodies. This both-sided configuration is the professional choice for custom harness assembly where both ends insert into pre-installed KK 254 housings, or where the harness bridges two PCB-mounted connectors.
The Molex KK 254 / MX5264 connector system is the industry-standard 2.54mm pitch locking connector for Arduino shields, PC fan headers, industrial PCB wiring, and general-purpose electronics — offering a positive-lock latch that prevents accidental disconnection, unlike standard DuPont friction-fit connectors. With a 22AWG UL1007 PVC conductor rated at 3A / 250V, this cable handles both signal and moderate power lines with confidence.
Key Features
- Genuine Molex KK 254 / MX5264 female crimp terminals both ends — precision-stamped contacts for reliable, low-resistance connections in KK 254 locking housings
- Both-sided configuration — female terminals both ends; ideal when both ends insert into pre-installed KK 254 housings
- 2.54mm pitch — the universal standard for Arduino GPIO headers, PC fan connectors, and general-purpose PCB wiring
- Positive-lock latch — KK 254 housing locks securely; prevents accidental disconnection unlike standard DuPont connectors
- 22AWG UL1007 PVC insulation — rated 80°C, 300V, 3A per contact
- Pre-crimped factory assembly — consistent, reliable crimp quality
- RoHS compliant
Typical Applications
- Arduino shield and module harness assembly — custom wiring between Arduino GPIO headers and shield connectors
- PC fan and cooling system wiring — custom fan header cables for PC builds and server cooling
- Industrial PCB signal wiring — PLC I/O module, sensor, and actuator connections
- 3D printer wiring — stepper motor, heated bed, and thermistor harness assembly
- Custom harness assembly — for KK 254 / MX5264 housing systems requiring pre-crimped terminal cables
- Replacement terminal cables — for repair and maintenance of existing KK 254 harnesses

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.
