"Obsolete" PIC parts

Or that you'd kept the old Westinghouse. In the basement we have a Bosch fridge from 1958. The compressor is designed for 50Hz and we run it at

Watch for wording such as "Not recommended for new designs". If in doubt call the manufacturer, they'll usually let you know and would suggest an alternate part.

If your design is very critical WRT how many decades it shall remain in production I'd consider switching to a 80C51 architecture. AFAICT they are the only series that truly has 2nd source, and even that only for certain packages. In terms of ubiquitousness they are similar to the Volkswagen beetle engine.

Assuming the voltage is correct, that should be better than the other way around (60 Hz motor running on 50 Hz).

it'd be an induction motor so it'd be running ~20% above design speed. basememt ambient temperature probably mitigates that somewhat.

• Check, used to use them back in the golden daze..

That is _SIR_ Ramic, i will have you know; harrumph!

(both Kighted and Indited)

I figured there was more margin in the max speed spec than the max flux density spec.

Not really. It runs a much higher chance of stalling out because the nominal voltage it sees now means undervoltage at 60Hz. Induction motors can stall under those conditions and then they go PHUT. But I assume the design of that fridge was so conservative that they didn't even calculate close to the make shaft torque.
