Exactly this is ACST6-7S http://pdf.datasheetcatalog.com/datasheets/120/156581_DS.pdf
Element available in the country in at least 2 stores.
Other producers? - I can see only one producer - STMicroelectronics.
In the network you can see the search for a replacement - no effect, tricks like here are used: http://holodforum.ru/showthread.php?t=12491 (MOC3041 + BT139) - but this seems to be possible only in some applications, because it is a triac (with high sensitivity of the gate) protected against surge voltage damage on inductive load.

Can you give the address of the store? I can not locate it anyway. I tried to replace BT139 before and it did not work.
