Can i use another H-bridge for this bipolar stepper motor drive?
L293D has an output current capacity of 600mA compared to L293 and SN754410 that can provide up to 1A in the outputs but apart from that the drivers have the same functionality and one can replace the other.

If you read the headlines of the SN754410 characteristics in the datasheet this is already noted
