Hello microtech50,
Welcome to the DigiKey TechForum! Unfortunately, I am unable to find LATWT170RELZK 532800 to use as comparison, and without knowing the part numbers or specifications you’re looking for we will be unable to advise on a part that might work. If you have a schematic or BOM of the television we can take a look and try to assist from that.

Klint, I have more info…that # i gave u was a CHINA # I found on the internet. What I need is to replace some backlight LED"s on a LG Model 47LN5400 TV. The backlight assembly has 2 different strip #s one is 6916L-1177 & the other is 6916L-1175A
I am looking to replace the bad LED’s I have on the strips I had ordered that # above they came in & the polarities on the solder pads were WRONG. I need the following polarity: LARGE soldering pad has to be+ & the small pad has to be -…they sent me the opposite polarity. I’m reasonably sure that the LED voltage is 3vdc. A lot of this stuff is coming straight from CHINA…I’m sure u deal with them too but it’s SO FRUSTRATING. I might have located the right one but the way they took the picture makes it questionable. I have spent MANY hours on line & can’t get aGOOD answer.
I will appreciate all U can do .
THANKS,
Ken
