content: Quote from: Faringdon on July 02, 2022, 11:31:37 amIt means that this particular part number, from this particular manufacturer, is obsolete.Digikey themselves list active variants of the SG3525 in various package options and from three different manufacturers (Onsemi, STM, Microchip). Only one part number is both active and in stock however, the SOIC16 package from Onsemi:https://www.digikey.de/de/products/detail/onsemi/SG3525ADWR2G/1485283

content: Quote from: wraper on July 02, 2022, 12:16:15 pmYes. Lead is now banned in much of the world and it's cheaper to make the same lead free part to sell all over the world, making the leaded versions obsolete.

content: "Obsolete" is a writing on the wall that you should not use this part for new designs and possibly redesign your existing products that use it becausd it may become unobtanium.

content: Quote from: Bud on July 02, 2022, 05:56:02 pmNot necessarily. Often it's just the lead package is obsolete, or they've stopped doing the through hole versions. The MC34072 is a classic example of this. They stopped making the through hole versions many years ago, but seem to want to continue to produce the surface mount versions.

content: Digi-Key might also say "obsolete" instead of "in last time buy phase". I've seen this recently. Still not a good sign!Quote from: mon2 on July 03, 2022, 02:31:37 amYep, Rochester is legit, don't hesitate to buy from them if you like their offer. I'll admit they often look sketchy as hell though!
