The "Y" I think represents a higher class of hfe, and they do have high hfe, just measure it with DMM. Whatever the brand, if it measures better then I think it should be a better transistor. ••• More options Share jaycee Member Joined 2004 2012-06-07 1:48 pm #6 2012-06-07 1:48 pm #6 left one by KEC, middle one unknown but looks good quality, right one by CDIL ••• More options Share Show hidden low quality content Status This old topic is closed.
