RD5.1EB2

Si Zener 5.1 V.5 circuits use this part.

Datasheet · from renesas.com

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.
