    ULN2003 IC replacement

    Hello, on a step motor driver board,
    I have found damaged ULN2003 manufactured by ST as package SOP 16 (narrow). Now I have possibility to order get delivered very fast the following mark: ULN2003AFWG,
    I'm not really sure if this is equivalent IC.
    On the original I can (hardly) read the following data: G001284, and on this replacement IC there is also this: 024826

    So, are these two ICs equivalent or not? First one is made by ST and second one by Toshiba. Based on the available manuals and schematics it should be 100% match.
    What I need to pay attention to?

    Thank you!

      Any part with ULN2003 and the same physical footprint will work. The other markings are datecode, etc. and are no-care markings.

      You can also review the offering by Texas Instruments. Stick to one of these brand names as opposed to an offshore one from Asia.

                  Failed UCC and Rubycon replacement on a Dell XPS410, equivalent?
                  by DXseekerMO
                  Hello, I'm working on an old Dell XPS410 with burst capacitors. I'm trying to source either an equivalent replacement, or a replacement that will work. It's been suggested to me to use Poly caps as a replacement, but I have no idea what to order or what will work.

                  If anyone has a link to where I can buy what I need that would be even better.

                  These are the caps that have burst:

                  Board location: C8BV, C26BV, C43BV
                  Brand: United Chemi Con
                  Series: KZG
                  Size: 10mm dia X 25mm height
                  Impedance: (ohms max/20c, 100kHz) .012
                  Ripple: 2800...

                  Nescafe Aeroccino, still fails with new Motor (red flashes only once)
                  by juergenb
                  Hi,

                  i am asking for some Help.
                  I have one of these Nescafe Aeroccino (Milk Frother) things with a bad motor.
                  The Motor didn´t start anymore and internet is full of users just swapping the motor for a Mabuchi RF-500TB-12560.
                  So i got a few of these from Banggood.

                  I swapped the motor and now i have a new fault condition.

                  In a working Frother you would press the start button, it will light red and work for a few minutes.
                  If you press longer it will light blue and just mixup the milk.

                  With the new Motor it just starts...

                  hi there,im having a look at repairing a wood lathe for my dad,(charnwood w821)the problem is when turning up the variable speed control,the motor starts to stop and start by itself,if i continue to turn up the speed it will trip the mcb in the consumer unit,there is also a slight smell of burning from the speed controll box.,Another strange symptom is the lathe can be unplugged from the mains after switching it off and the motor will spin a couple of times by itself,so far ive put a new speed controll potentiometer on and new motor brushes,ive also tested the motor windings and everything looks...

                  Macbook Air M2 A2681 Kernel panics after screen replacement
                  by reformatt
                  Just had a customer bring in a M2 MBA A2681 that had had a screen replacement in April at another repairer. Since then, she has been getting intermittent kernel panics. It's an aftermarket screen, and of course it fails in diagnostics as the calibration hasn't been done. The error in the panic log is "No device added after powering on the rails".

                  It seems the original repairer has swapped the board and the screen to other MAC's, and said that it isn't a screen issue. From what I understand, by doing a quick search on Google, this is in fact a screen issue. The panic relates...
