Let's try this again:
They are HP/Agilent/Keysight PN 10811-80008. I was actually able to buy
a couple from Agilent a few years ago. They are listed as obsolete
now. A Panasonic EYP2BH115 should fit. Newark has them.

I believe a thermal cut-out is a device which interrupts the circuit
when a prescribed temperature is reached or exceeded (in some cases
by heating from an increase in current through a conductor), but
which re-connects the circuit once the temperature has dropped below
the cut-out temperature (possibly with some hysteresis built in). A
fuse, on the other hand, interrupts the circuit after a certain
current threshold is exceeded (and, of course there is an increase in
temperature related to the increase in current) but which is destroyed
in the process out interrupting the circuit.

I'm sure this has been discussed to death before, but does anyone
know of a source of thermal fuses small enough to fit in the -hp-
10811? I have found plenty of larger ones, none of which will fit
and would rather not just link it out.

Thanks for all the tips and advice.
The Chinese eBay ones (15A) I have bought before and they are
physically too big to fit.
Buerklin is a German distributor and will want 28 Euros to ship to
the US.
I know I can link it out, but don't like doing that in something that
is powered on permanently.
I have found some Panasonic ones that Digikey distribute in the US,
but frustratingly the data sheets have no dimensions given. I have
ordered some 1A and 2A ones to try, and will report further.
I suspect that the originals would have been around 115C. And for
searching they seem to be called Thermal Cut Outs (TCO), not fuses.
