Lookalikes and how to tell them apart
In between SH and PH: 1.5 mm. Next to a PH the difference is easy to see; on its own, measure across all the pins.
| Connector | Pitch | Latch | Per contact |
|---|---|---|---|
| JST ZH | 1.5 mm | no, held by friction | 1 A |
| JST PH | 2.0 mm | no, held by friction | 2 A |
| JST SH | 1.0 mm | no, held by friction | 1 A |
| Molex PicoBlade | 1.25 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 ZH connector?
1.5 mm between the centres of two neighbouring contacts.
How much current can a JST ZH 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.
