Im using a circuit design I found on the internet but I cannot source some of the transistors that were used in the original circuit and Im having difficulty finding replacements. Could anyone look at the following datasheets and tell me would it be ok to substitute the 2n3703 for mps3703. 2n3703 https://www.farnell.com/datasheets/46840.pdf mps3703 www.datasheetcatalog.org/datasheet/fairchild/MPS3703.pdf The circuit Im trying to build is in this application note www.psocdeveloper.com/uploads/tx_piapappnote/an2313_01.pdf Thanks in advance
