Don't worry -- leaded parts aren't going away anytime soon. We still have access to every part we designed into the K2 over five years ago. Reply: ----------------------------------------------------- Leaded parts may not go away, but may be increasingly difficult to obtain. Some types of IC are a case in point where the DIL type are getting very difficult to source and new types of devices are only available as SMD. There is a way around this in adapting a similar SMD IC with a DIL header adaptor, but this would become impractical if the number involved get too great. All volume manufacturers of equipment seem to be changed over to using SMD which can only hasten the decline. Have been involved recently with sourcing some CTCSS decoders for home constructed repeater logic systems. Very little is now available in DIL format as the radio manufacturers have only only used SMD for quite a long period. What is little still available in DIL commands quite a hefty price premium compared to the SMD type. More worrying if the information turns out to be correct is that Toko are reported in the UK PW radio magazine for May 2005 to be ceasing manufacture of through hole PCB type transformers and concentrating on surface mounted types. Unless another source is found of these components, this could make home construction though not impossible, a great deal more difficult.
