not a clue about that, but also dont go for SONY-NEC-OPTIARC 72xx series. i have reasons to believe that you wont find an open can inside. 7203 has flat frame LDs.
I'm so glad this technology is so cheap. Still can't believe it's cheaper to buy more electronics solely for the LD then it is to buy the diode itself. lol what a world we live in. - Thanks Jay, the Sony it is!
