I like Reichelt in theory (and LOVE that they still give out printed catalogs, updated 1-2 times per year!), but their website is so bad that I’m usually willing to pay more to order from Digi-Key. The parametric searches are awful, when available at all, and above all, you can’t just click “back” to return to the results of a parametric search!!
(It always requires an “are you sure?” dialog, followed by a full — slow — page reload.) More than once, it’s lost my shopping cart
during shopping on the same computer. It did that
twice on my last order.
On the other hand, they carry some stuff that’s hard to find, and their single component prices (especially for passives, connector parts, etc) are often similar to Digi-Key’s @1k prices.
