Lookalikes and how to tell them apart
3 contacts at 2.54 mm with + in the middle. Futaba plugs have a key tab, JR and Hitec plugs don’t: a Futaba plug fits a JR socket only with the tab trimmed.
| Connector | Pitch | Latch | Per contact |
|---|---|---|---|
| Servo plug | 2.54 mm | no, held by friction | — |
| Dupont | 2.54 mm | depends on the version | 3 A |
| Molex KK 254 | 2.54 mm | no, held by friction | 4 A |
Before you plug it in
Crimp terminals need the crimper die made for their size: pliers crush them and the contact works loose. Housings and terminals of different series don’t mix, even at the same pitch.
The current rating is a maximum per contact, at the wire size the maker states. With thinner wire, or with every contact carrying current, stay well below it.
