Honored ContributorUpdate, comparing data 04 and 08 are the same pinout, 40 50 differ from so vertical migration is not true, why pin compatibility is not mantained across same case where I/O are same?? This resulta trouble too, I needed develop usingg large device then mount an SC04 or SC08 on final deviice but now pcb cannot accept it.
Original issue probably was just a short circuit under the qfp or max10 defective, I try place on a test socket to investigate but it was exposed to 290°C when reflowed for rework... NOw board need another rework and replacement of expensive 50SC part.. DAMN!!! Checked 02SC 04SC 08SC 40SC 50SC, appear Altera made 3 different series on same package: 02SC is just compatible itself and not with other members. 04 08 are compatible thru 25, only 04 08 checked, 40 50 are exchangeable themselves only but not with other member of SC series.
