RD5.1EB3

Si Zener 5.1 V.2 circuits use this part.

Substitutes same voltage

Zeners of the same voltage. The figures are read off each part's datasheet (this one's from page 4), 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.
