I can find L14P2 (10us risetime) but not L14C2 (5us risetime).  Does
anyone have a spare kicking around?  I'm in Massachusetts, USA.

Thanks for posting your parts availability.  I'll have a look through
and compare datasheets to the L14C2 to see if any of them might be
appropriate.

This is for an old (1980s, I guess) camera shutter-speed tester to
which I'd like to add a remote sensor to make it easier to use for
some types of camera equipment.  I know nothing about the  unit's
operation and don't want to rip apart my working one (it's held
together internall with hot glue) to figure out how it works.  All I
know is that someone else used an L14C2 for this modification some
years ago, it worked, and he documented it online.

The L14C2s on ebay are quite pricey.  A (much cheaper) L14P2 arrived
yesterday, perhaps the difference in rise/fall won't matter.

Shutter speeds are, what, milliseconds?

If you don't need the TO5 package, plastic parts are cheap. Mouser has
hundreds in the 30 cent range.

Better yet, design something new.
