My experience with regards to delivery times from E14, RS Components, Mouser and dDigikey:
- E14 & RS Components - if local stock is available in Australia I have always received the parts next business day. If the stock is available but not in Australia I have learned that it could be from the advertised 5-7 business days, but it can easily stretch to 3-6 weeks.
- Mouser - Available stock normally comes in 3 days, but sometimes gets delayed for some reason to 4-6 days, not often tho. Good think is that packages also arrive Saturday and Sunday sometimes.
- Digikey - this is the winner for me with regards to delivery times, 2-3 days sharp and have never missed so far. Also in recent times I have started to receive the goods over the weekend as from Mouser.
