I am currently looking for new FET. @chrisdo mentioned link to the proper part at digikey in other thread. For me digikey is a bit complicated, because they charge 18€ for shipment, and especially when they use UPS only. European VAT, UPS + customs clearance automatically means that I will be paying for 20 FETs 6,62€ + 18€ shipment + 24% VAT + 18€ UPS handling fee (customs clearance handling fee). Ebay and amazon had some 1-2 chinese options available, not really cheap and long delivery times.
If someone is looking for other than digikey providers for IRLML6244TRPBF FET , I think this gives a good overview about the options available: https://octopart.com/irlml6244trpbf-international+rectifier-18793198.
Many of those sell only full reels (3000), but cut tapes quite often available too. Not all sell directly to consumers, but at least TME does in Europe. And they seemed to be quite cheap. TME did not have picoblades available at all, so I ended up using Elfa Distrelec (which is not actually on that list - but with part number googling is quite easy).
All the above is valid for motor connectors, just use part number WM1731-ND to find the product.
Hope this helps someone.
