I have a quick question on a JST SSH part number.
I’m currently using JST SSH-003T-P0.2-H in a cable assembly, but can’t find much stock available. In looking for appropriate alternates, I was able to find JST SSH-003T-P0.2. Unfortunately, I can’t find datasheets on the JST SSH-003T-P0.2 part to do a proper comparison between them. Digikey has a p/n for the SSH-003T-P0.2 (Digikey p/n: 455-1561-2-ND; associated URL: https://www.digikey.com/en/products/detail/jst-sales-america-inc/SSH-003T-P0-2/700389), however the datasheet tied to that is for the updated p/n SSH-003T-P0.2-H.
Was the SSH-003T-P0.2 part an older JST part number that was replaced by SSH-003T-P0.2-H? Does anyone know where to look for an old datasheet tied to SSH-003T-P0.2?
Hello Aha1 and welcome to the forum;
I did review the SSH-003T-P0-2 page and found that http://www.jst-mfg.com/product/pdf/eng/eSH.pdf had the reference to the contact on page 1 in the bottom left.
In my survey I could not find a more detailed drawing.
The H callout is for High Pressure contact. It would have a higher friction with the mate than the non-H, but otherwise the same contact.
Hello Michael and thanks!
Thank you for taking the time to review this. I’ve reviewed the associated pdf and saw what you were referencing.
Additionally, I found the following in the JST FAQ (https://www.jst.com/resources/faq/#jumpTo) → SH/SR series-> “What does the “-H” indicate in the SH series contact?”
“What does the “-H” indicate in the SH series contact?”
Contact with the “-H” suffix…
Contact without the “-H” suffix…
Part number SSH-003T-P0.2-H is a newer version and is called a “high-pressure contact type” compared to the older SSH-003T-P0.2. The contact point of the contact was modified for a more assured connection and to help prevent the contact from warping when mating with the header posts.
Both contacts share the same application crimp tooling for terminating to the applicable wire. For more information, please visit (https://www.jst.com/)."
