Hey everyone, I'm new here and signed up in hopes of finding an answer to my problems.
I'm an Australian student trying to create a powerful 1/4 scale R/C car, and with the hopes of controlling the car with a windscreen wiper motor, since they have enormous amounts of torque (due to their worm gear structure). I have turned up a schematic for a simple H-Bridge but the only downside is that it seems to use outdated components. I was wondering if anyone would be able to help me find some alternatives for the parts. I have searched across using data sheets and such, and I just simply don't have the knowledge to do this.
Included is the schematic to help. Another thing is, the biggest electronics supplier I can find in Aus (around my area) is RadioSpares Components, website here. So, if you have any applicable ideas for this circuit (or even another simpler circuit design!) it would be much appreciated if you could first search it, or at least post the component so I can search around for it myself.
Since I can find the CNY17-1, capacitors and resistors, the only alternatives I need are for the,
(data sheets linked)
2N2220 NPN Silicon Planar Transistor ( Data sheet ),
BDW93C NPN Darlington pair ( Data Sheet ),
BDW94B PNP Darlington pair ( Data Sheet ).
Now, for the 2N2220 I have found here that I could also use the NTE123A. I'm not sure about this, so if anyone could confirm that it is a possible replacement, especially with checking against the circuit.
Also, for the BDW94B I found that I could use the NTE2343. The complimentary to that is the NTE2344 which is included in the data sheet linked.
The biggest issue here is of course availability, otherwise I wouldn't have to change the parts.
Thanks anyone who can help out here, I'll really appreciate it, if anyone wants to see the project as it is, I'll post photos.
Thanks,
Kyle.
