Can I substitute this chip INA260AIPWR with INA260AIPW for the ULTRA Build?

Can I substitute this chip INA260AIPWR with the INA260AIPW as the second is in stock but the accuracy is .15% Vs .02% for the INA260AIPWR, otherwise they seem to be identical according to the spec sheet.

Cheers!

As far as I can tell they are identical parts but come in a different package Qty from TI (90 vs 2000). Where do you see the part about the different accuracy?

Either way it's fine to change. I have tried both.

We should prolly change the part number on the BOM

Hi skot thank you for your reply, I found the difference in accuracy in the specs sheet on the digikey site if you scroll down a bit on the product page

Just one is in stock and the other has a December availability from digikey and mouser and no one else seems to stock it apart from the Chinese clones on AliExpress which I am not to keen on trying lol

Oh also is there a different part we could use for the ss310 used in D1 as that is also out of stock.

Cheers!

huh, I see what you mean. That must be Digikey parsing it wrong. they both link to the same datasheet which says the range is 0.02% to 0.15%. Feel free to use whichever part you can get.

I made a separate discussion for D1; #85
