Making a Darlington transistor (eg: TIP120) with D882 to drive 12V LEDs with 3.3V or 5V input RPi

Question

I am getting into circuits and trying to improve my knowledge but even though it might sound like a silly question but here is my story short:

What I am trying to do

I am building a circuit to drive an LED strip (12v) out of a Raspberry Pi using PWM output.

It worked out perfectly using a TIP120 on the breadboard using the following example:

My goals

Now that it is working, I am building a PCB to send to JLCPB to have it printed and assembled so I wish to use basic parts as much as possible and ended up selecting a D882 transistor which is not a Darlington. I heard that it might cause issues to my actual circuit and not expecting the same result as with the TIP120.

So a using D882 transistor I kind of recreated the schematic of the TIP120.

Am I silly to say that this will do the same thing as the TIP120?

Am I in the wrong way and another SMD component would do the trick?

Update

Channel 1 at 100%, seem to get alot of noise but Channel 2 at 50% is quite stable.

Here you can see the quick simple prototype

Answer 1

If you just need a surface mount version of a tip120, the MJD122 would work, but I would recommend the fallowing to protect your GPIO from the 12V, which is 3.3V i/o on a raspberry pi.

Now, if we use an enhancement mode MOSFET instead of a darlington, then the low voltage cmos from the raspberry pi (2.5V logic hi) would drive the circuit efficiently, and more like a switch. So I would recommend for raspberry pi, this kind of driver circuit:
