612-ASP-237788-01TR-ND is a new, custom part made by Samtec. There isn’t any information available yet on the product display plage and there is no current datasheet, so this makes it difficult to find a mate that works. I was able to ask Samtec for more information on the part. They informed me that the part has a 30 x 4 pin configuration. They also told me that the part is able to mate with any SEAM series connector as long as the pin count is the same, regardless of other specifications. Their part configurator for SEAM connectors is found here. We do have a list of components that should be able to mate with this part based on the information, please see below.
Thank you,
