Frequently Asked Questions

Q: What is the difference between JST 1.25mm, PH 2.0mm, and XH 2.54mm connectors?

A: The numbers refer to the pitch — the center-to-center distance between pins. JST 1.25mm is the smallest and most compact, ideal for tight spaces such as small battery packs or micro electronics. JST PH 2.0mm is a mid-size connector commonly used in RC hobby electronics and small appliances. JST XH 2.54mm is the largest of the three and is frequently used in PCB connectors, 3D printers, and general-purpose electronics wiring.

Q: Do these connectors come with both the male and female plugs included?

A: Yes! Each set includes both male and female plug connectors, already pre-wired with the appropriate AWG wire and cable length — 15cm for the JST 1.25mm (28AWG) and 20cm for both the PH 2.0mm and XH 2.54mm (26AWG). No additional crimping or tools are required.

Q: What voltage rating are these JST connectors rated for?

A: These connectors are rated for low-voltage applications up to 24V DC, compliant with EU LVD standards (below 50Vac or 75Vdc). They are suitable for battery connections, LED lighting, and other low-voltage electronics projects.

Q: Can these connectors be used in automotive or robotics applications?

A: Absolutely. These JST connectors are designed for versatile use including automobiles, robotics systems, household appliances, toys, lighting setups, and PCB control panels — making them a go-to choice for both hobbyists and professionals.
