I'm planning to crimp SSH-003GA-P0.2 crimp terminals to go into JSTSHDR-20V-S-B connectors.

How do I figure out which is the proper crimp tool I have to use to succeed?

Thanks in advance.

  • \$\begingroup\$ A similar question has been here before years ago. The answer is similar. Use the vendor recommended tool or a near as possible alternative based on crimped terminal dimensions. I was offered a simple over centre parallel jaw action hand tool by a JST agent in South Africa when I purchased ten thousand contacts and it cost more than the contacts. It is fiddly work to get good crimps but possible with care I only needed a few hundred contacts all told but there were no easy alternatives. Pre-crimped is a good idea when available, if ordered from a harness supplier it may save you time.. \$\endgroup\$

  • \$\begingroup\$ My experience with this problem was 20 years ago so you will have to locate your own JST supplier and ask them. \$\endgroup\$

When you go to the Digikey page of the SSH-003GA-P0.2, you can scroll down and see the Tool section.
This specifies the YRS-859 as compatible hand tool.

That is super easy. When there is no tool section, you can look for "other customers also bought", or "relevant products" that you often find at the bottom of any online store. There will at lease be some hints in here to brand or off-brand tools.

It also specifies the tools per part in the table available from JST.

Which for JST is obvious, but some lesser known brands might not be clear about this.

  • \$\begingroup\$ @Jeroen3 thanks for the answer. The price indeed is pretty unreasonable. Are there any good ways of looking up for some alternatives? Besides the digikey 'another people also bought'/'relevant products' sections? Thanks \$\endgroup\$

    \$\begingroup\$ @user59271 Yes, buy them with wire already crimped on. \$\endgroup\$

    \$\begingroup\$ I've used a variant of that tool. It's so expensive because it is a production grade tool. It takes in a roll of pins and cuts the pin off the roll with every shrimp. It does not auto-forward which would have been nice, but it has detents that allow easy pin alignment. The tool is rated for tens of thousands of operations. The cheaper tool loads pins one at a time by hand. \$\endgroup\$
