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

There are no capitalized pork products in my email address.

John,

Thanks for listing your stock. I'm looking for an exact replacement
as I have no information about the current unit and it's not a high
enough priority for me to rip it apart and try to figure it out. I
did see the units on ebay but the prices are more than I can to pay to
add an auxiliary function to an already-working unit.

I did pick up an L14P2 and will try that. It's for a camera
shutter-speed tester and perhaps the difference in rise/fall won't
matter.

Steve

John,

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.
