EPROM pin replacement compatibility questions

<< < (4/4)

analogix:
So it only has to do with the markings on the outside, not with how they're set up inside?
Are there 16-way rotary DIP switches with decimal number labelling (i.e. .....7,8,9,10,11,12....)? I've only found ones with hex labelling.

Also, are there rotary DIP switches which can be front panel mounted (like a potmeter)? For my project I need both PCB through-hole right-angle mountable DIP switches (no problem finding those) and the equivalent with front panel mounting.


oPossum:
Thumbwheel or pushwheel switches are typically used for panel mounting.

Pushwheel with 0 to 15 markings... https://www.datasheets360.com/pdf/5841758742966473284

If the switch is marked 0 to 15 then I would call it BCD. Decimal digits are 0 to 9, but decimal numbers can have may digits.

BCD only has a range of one decimal digit per coding group. (Typically uses 4 bits to encode the digits 0-9 and "wastes" 6 of the possible states.) So a BCD selector would naturally have a range of 0-9, not 0-15.
