What is the analogue of the TLC5927 and TLC5940?

Question

Electronics

Good day, there is a need to make something like an LED screen that would be controlled through shift registers (if you advise something else, I will be glad), the essence of it is that it has some segments that do not have color gradation (grayscale) , and some have, I found on the Internet a specification for TLC5927 and TLC5940, "it seems" everything is clear, but it takes a very long time to eat these chips and they are not ready to sell 5 pieces everywhere ...
I found MBI5031 and MBI5368, but not all offices supply them. ..
Knowledgeable people, tell me, are there any analogues? Or in general, this almshouse can be replaced with something simpler?
Technical requirements
- current per channel from 60 to 120 mA
- voltage 12V
- PWM 8 bit for gradation 255 shades (1 channel, grayscale), that part of the LED that has shades
- PWM 8 for all channels (there is a task to make the overall brightness higher or lower)
I would be very grateful to you!

TLC5940 is sold on Aliexpress.
Regulators by parameters can be selected here: https://www.compel.ru/catalog/ic/power-conv-int/le...
Also look towards ready-made matrices, it's really easier: https://ru.aliexpress .com/item/P3-RGB-pixel-panel-...
Or in the direction of controlled LEDs like WS2812, SK6812, etc.
