[Elecraft] Part labelling or inventory anomoly?

[Francis Belliveau]

I got the K2 Keying Waveform Modification kit for Christmas but had to
travel for work so I finally got around to installing it yesterday.  When I
inventoried the parts I noticed that what was supposed to be a 508-3081 PIN
diode was actually labeled something like 349-3081, at least I think those
were 3's and 8's.

Is this a valid part substitution?
