Hi,
I am trying to replace 0402 R, L, Cs with 0201s on my design on a Bluetooth and wireless charging board. How do I check which ones I can replace and which ones I shouldnt, or can I replace all? The use case requires me to minimize the board size even if the cost goes up a little. For example, for a 1K resistor, Digikey shows power of 0.063W for a 0402 with a cost $0.004 for 100 pcs, while for a 0201 it shows power 0.05W and a price of $0.0166 (all other characteristics are the same). So does power here matter much? Or if the price increase doesnt matter, is it ok to replace 0402 with 0201?
