Where to buy opamps and other useful IC assortment kit components in the USA

<< < (3/3)

robsims:
Many thanks Dubbie for helping me out.
Should i buy the kit from ebay or the one i posted earlier

Ebay:
https://www.ebay.com/itm/Linear-IC-Kit-Analog-Assortment-of-Op-Amps-Comparators-Regulators-Converters-/282943781205

The link i posted earlier:

ledtester:
All of the chips in the ebay listing are classic devices and suitable for learning about op-amps.

For comparison I put together a Mouser order to come in under $20 including shipping. It only contains op-amps and comparators and doesn't include the LM1458N or NE5532. The only advantage of using a commercial distributor is you know the chips will be handled and packaged well. Although, the ebay seller has 100% positive feedback, so the guy probably is careful with his handling and packaging as well.


robsims:
Many thanks for the list ledtester. I'll go with you're list and order them from Mouser. Thanks again

Kleinstein:
For simple stuff (e.g. resistors, LEDs, LM358), chances are good to still find non fake parts on Alibaba  and get the directly from China. There is no need to go via US. Chipping from China to the EU and US is usually really cheap - should not be that different to other countries.

For more higher end parts chances are high to get fakes -  so ordering from something like Mouser via the US may be a good option.
