Does anyone know if the BC182/3/4/212/3/4 transistors have been reincarnated as surface mount devices with different numbers or have they really been completely discontinued?
I know that TO-18 packaged BC107/8/9/177/8/9 became the TO-92 packaged BC547/7/8/557/8/9 and then SOT-23 packaged BC847/8/9/857/8/9.
I tested BC557 vs BC212 for the input stage of audio power amplifiers about a decade ago, and the BC212 came out considerably better; I've just returned to designing a few power amplifiers and was wondering if the BC212 is gone for good.
A search on a well-known internet search engine suggested 2SC1623, but the datasheet graphs are nowhere near the same, and I found a 2007 forum post by @Audioguru again (before he was "again") suggesting the 2N3904/6.
