I've been having trouble finding pairs of connectors. I need a set up exactly like https://www.artekit.eu/products/prototyping/wires/jst-ph-4-pin-cable-with-male-female-connector/

enter image description here

However, I need to buy the male and female parts separately. So, I'm looking at male connectors like https://www.digikey.com/product-detail/en/jst-sales-america-inc/S4B-ZR-LF-SN/455-1671-ND/926578

enter image description here

But then how, having just the male connector, do I go about finding a female connector which I know will fit into the male connector?

I'm having a lot of trouble figuring out how to verify my connectors will fit correctly. I would think the male and females would be linked in some manner that I'm missing?

  • \$\begingroup\$ Either really, it's for I2C lines. It's just, I need a connection that snaps in place, and if the male and female don't snap in the same way I don't think they'll fit together. \$\endgroup\$ – Alex Byars Apr 26 '18 at 22:08

    \$\begingroup\$ Don't be so quick. This might seem obvious to you, but I looked for a long time without realizing where to find the answer. Transistor's answer helped me quite a bit and could help others in the future. \$\endgroup\$ – Alex Byars Apr 26 '18 at 22:20
  • \$\begingroup\$ "But then how, having just the male connector, do I go about finding a female connector which I know will fit into the male connector?" - well, after clicking on that Digikey link you already have, you scroll down to the bottom and look at the section labeled "Mating Products" ... \$\endgroup\$ – brhans Apr 27 '18 at 0:47

On the web catalogue page you linked is a link to the manufacturer's datasheet for the ZH series connectors. This will contain tables of all the compatible connectors in the range.

enter image description here

Figure 1. Top and side-entry versions with through-hole or SMT options.

Choose the orientation you require (top / side entry, etc.) and the number of ways and you will find your part numbers.

Then return to Digikey and search for the ZH part numbers.
