SOP44 socket adapter for Wellon programmers Converts from a DIL ZIF socket to SOP44 (1.27mm pitch, 15.9mm width) (IC51-0442-1536(1208)). Can be used with Wellon and other programmers. Your Wellon programmer's Supported Devices List will show only WL-SOP44-U001; the -TC on this part number simply indicates that this is the clamshell type of socket. The open-socket version is available on request.
Some adapters bear the older part number WL-SOP44 on their silkscreen, as seen in the photo.
