Source for 30ppm of Teensy 4.1 Crystal

Hi, I know this is not the proper place to ask, but I've been looking for a source for the 30ppm of the Crystal of the Teensy 4.1 for quite some time. As your list states 30ppm I guess you know one... It would be greatly appreciated if you could reply it or mail it to me to julian@fius.de :)
