How about 74ahc595?
Some available

https://www.ebay.com/itm/15pcs-new-74AHC595D/142818321022?hash=item2140a2a27e:g:acoAAOSw6VNbEiq4

I have tried all the available AHCT595 TI, Phillips, NXP, Nexperia, Diodes.
The fact that Nexperia is different from the NXP discovered quite recently.
The new Nexperia has lower consumption than NXP. SNR worse by 3-5db.
I believe that you do not need to re-install already installed Nexperia. By ear, you will not notice this difference.

Find Phillips or NXP is difficult now. Remains of NXP still exist in some warehouses. But to search you need to make an effort.
I had a stable supplier Phillips, but I cleared his entire warehouse.:)
Try searching on TaoBao. In the warehouses of China NXP you will find. Do not worry about fakes. These ICs are not profitable to
counterfeit.
 
Pavel,


Can you post a picture of an old stock NXP chip? I might have a line on some but I want to verify it's not a Nexperia.

Thanks to Pavel’s gerber, I’ve got some blank boards made according to his suggestion. Some spare sets left, if anyone interested. :) If there’s enough interest, I could provide the Philips AHCT595.

Dear Pavel,
on the board is Part WM18900-ND, what is the fitting connector to supply power?
0050375023 Molex, LLC | Connectors, Interconnects | DigiKey
and 08-70-1039 Molex, LLC | Connectors, Interconnects | DigiKey
Where to get the 2x37 connector (1.27mm) 20021311-00074T1LF. Nobody seems to have this connector in stock. Any Ideas??
I used 2х40 20021311-00040T4LF Amphenol FCI | Connectors, Interconnects | DigiKey
And manually deleted 3 positions of contacts.
