1n4004

The ON 4004 included on the BOM is now listed as obsolete. Mouser has ON 4004RLG (http://www.mouser.com/Search/ProductDet ... -1N4004RLG) as a replacement. It's on backorder @Mouser until March 2018 but is available from DigiKey. Is this a suitable replacement?

On closer inspection, it appears that all of these would work as well: https://www.digikey.com/products/compar ... F54GICT-ND

Am I right? Any advice from someone more knowledgeable would be greatly appreciated!

1N4004 is a standard diode, any brand can replace another.

4005 or 4006 will works perfectly fine also

RLG only means they are on Tape and Reel and Lead (Pb) free. Better for your health so to speak..

figured this out after posting

Thanks for taking time to answer tho!
