The part numbers are different
The sense amplifier is different
Take care !!!

Thanks

Looks like the

1826-0158 is for the HP-65

and the

1826-0322 is for HP-67, HP-97, HP-41 82104A card reader, but seems to work on your HP-65.

They might be different because of the different ways these calculators read/write the cards.
Maybe the 1601A03250 HP-65 had a replacement done at some stage.

cheers
