Part Number interchangeability

[huxwar]

If a Part No, ie: 7EO 919 475 M, needs replacing does the new part need the exact same Part No, or can the end letter be different?
i‘ve seen 7EO 919 475 T and 7EO 919 475 K for sale are these compatible?
maybe @Pauly or someone else with part no guru status may know?

For this specific example - I guess they are interchangeable - based on data on IFI CP2 Message

But then e.g. 7E0 919 475 L or N definitely are not - because of different functionality (8 channels instead of 4 in the examples).

That makes sense. Many thanks
