I am new to DIY and, of course,this project and need some help on part substitution. I am based in the U.S. and have been looking at the Mouser sight for the LPC17 parts list. Currently there are three parts that I was wondering about regarding compatibility: Life Cycle Ended Alternative presented ================== ===================== 140-HTRL25V47-RC 140-RGA470M1EBK0511P 140-HTRL16V100-RC 140-RGA101M1CBK0611P 140-HTRL16V2200-RC 140-RGA222M1CBK1325P The URL's to the alternatives that Mouser is presenting are as follows: 140-RGA470M1EBK0511P - http://www.mouser.com/ProductDetail/Lelon/RGA470M1EBK-0511P/?qs=sGAEpiMZZMtZ1n0r9vR22Z8b58wL7Nwvtfo6xCJ7FFs%3d 140-RGA101M1CBK0611P - http://www.mouser.com/ProductDetail/Lelon/RGA101M1CBK-0611P/?qs=4ZuRpliPd6yW%252bYRSlC8UhQ%3d%3d 140-RGA222M1CBK1325P - http://www.mouser.com/ProductDetail/Lelon/RGA222M1CBK-1325P/?qs=4ZuRpliPd6yYgrkX404uEA%3d%3d I was wondering if these alternatives were good and useable. If they are not it would be great if someone could recommend an adequate alternative as well as a parts source that provides the alternative. Thanks for your help! -Ken Q.
