1N5240B

Si Zener 10 V 500 mW DO-35 TH.1 circuit uses this part. Listed as: Zener diode, 10V 1/2W.

Substitutes same voltage

Zeners of the same voltage. The figures are read off each part's datasheet (this one's from page 2), typical where the sheet gives a typical value, otherwise the maximum. Closest first; the last column says what differs. A different part can change the sound, and a circuit may lean on one particular figure, so read the build document's notes before you swap.
