Most of the times finding the electronic parts in Sri Lanka is (extremely) difficult process. Lots of electronic part suppliers have fast-moving electronic parts only. (such as general resistors, capacitors, semiconductor devices related to the Hi-Fis, TVs and general consumer electronic products, etc.) For my electronic experiments I'm getting most of these “uncommon” electronic parts from following suppliers,
Farnell : Farnell is my "number one" choice for most of the “uncommon” electronic parts and instruments, specially semiconductor devices and test instruments. Compared with other suppliers there prices are bit high but also had a nice service and higher reliability. Most (all ?) of there parts are coming from reliable and popular vendors. Most interesting thing is “There are no minimum order quantity levels in there orders”, which means I can order 1 unit of electronic part from them.

Silvertones Ltd : Silvertones is one the oldest electronic part supplier in Sri Lanka and they also have good collection of electronic parts. Most of the Silvertones parts are coming from branded electronic part manufactures, due to this reason some of there parts are bit expensive than standard once.

DigiKey : Digikey is one of the world's largest electronic component supplier and unfortunately there are no any local agents for DigiKey. I brought some hard to find electronic parts from them via online and there service is also excellent. Only problem in DigiKey is it's higher shipping and handling charges.
Other than these local/international suppliers eBay have several electronic part suppliers. Most of them sell lot of rare semiconductors and other electronic components. Most of these eBay suppliers ship parts with free of charge and they are not much expensive as DigiKey or Farnell.
