I'm trying to get some of the above, we use several hundreds a year. Usually no problem as we have kept some in stock but now things have gone a bit pear shaped with the product so no stock. :(
Mouser will have some in May, and that's ok, but the website info is a bit of a mess. I had a live chat last night and the "chatter" was confused. He was going to reply by email but still hasn't. As you can see below the LF version seems to be the lead free version but the R/H side of the screen shows one at 2% and the other at 20% with varying number of resistors.
I can get other manufacturer's R2R but they all seem to have the pins reversed (and rare as hens' teeth). I can make provision for both as I'm making a new run of PCBs.
So if you know where I can get some NOW (300??) of either types please let me know. I'll do the net run around again today.
