I'm currently looking for some FLASHPRO4 peripherals, which are naturally hard to find as they are old devices, and the reputable dealers like Digi-Key, Mouser, and Newark all have none in stock. If I go to a site like Octopart, there are multiple sites listed that claim to have thousands in stock, but they require that I input a bunch of my personal information just to get an RFQ. It feel suspicious to me, why can't I just buy the part like on Mouser? Why do they need my personal information before I can even attempt to buy the part? Is it just a ploy to get my personal information? If anyone has any personal experience or knowledge about these oddball electronics dealers, I'd love to hear about it. Are they legit? Or do you put in your personal information only to find out that the part isn't really in stock? All input is appreciated.
