The difference is the inner pin diameter — 2.1mm vs 2.5mm. It's important to match the inner diameter of your device's power jack. The 5.5×2.1mm is more common in general electronics, while 5.5×2.5mm is often found in higher-current applications. This product supports both sizes, making it highly versatile.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I use this connector for 12V DC power supplies?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! This DC female socket connector is rated for voltages below 50V AC or 75V DC, making it perfectly suitable for 12V DC power supplies commonly used in CCTV cameras, LED lighting, and electronics projects. Just ensure your current requirements are within the connector's capacity.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I wire this DC socket connector?\u003c\/h4\u003e\n\u003cp\u003eA: The connector comes with a pre-attached ~20cm pigtail cable. Simply strip the wire ends, identify the positive (center) and negative (outer) conductors, and connect them to your power source or circuit board terminals. The copper core ensures a reliable, low-resistance connection for stable power delivery.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is the difference between the 5.5×2.1mm and 5.5×2.5mm DC connectors?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Both are standard barrel-style DC power connectors with the same 5.5mm outer diameter.
