Lookalikes and how to tell them apart
The only common 1.25 mm connector with a latch you press. PicoBlade and DF13, at the same pitch, just pull out.
| Connector | Pitch | Latch | Per contact |
|---|---|---|---|
| JST GH | 1.25 mm | yes, a tab to press | 1 A |
| Molex PicoBlade | 1.25 mm | no, held by friction | 1 A |
| Hirose DF13 | 1.25 mm | no, held by friction | 1 A |
| JST SH | 1.0 mm | no, held by friction | 1 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.

Frequently asked questions
What is the pitch of the JST GH connector?
1.25 mm between the centres of two neighbouring contacts.
How much current can a JST GH connector carry?
1 A per contact with AWG 26 wire, at up to 50 V, according to JST.
Figures from the makers’ catalogues and datasheets. Ratings are maxima: derate for thin wire and for many loaded contacts.
