Substitutes same kind

Diodes of the same kind; for clipping, the forward drop is what you hear. The figures are read off each part's datasheet (this one's from page 1), 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.

This 1N60P is a Schottky, not a germanium point-contact diode, though it is often sold as a germanium substitute.

Alternatives

Part	Vf	If max	Vr	trr	Cj	Package	Boards	Differs
BAT46	0.25 V @ 0.1 mA	0.15 A	100 V		10 pF	DO-35	115	Low-drop Schottky clipper, about 0.25 V at 0.1 mA, with a 100 V rating.
BAT43	0.33 V @ 2 mA	0.2 A	30 V	5 ns	7 pF	DO-35	2	higher forward drop. Same die as the BAT42 but specified at low current: 0.26-0.33 V at 2 mA.
BAT42	0.4 V @ 10 mA	0.2 A	30 V	5 ns	7 pF	DO-35	18	30 V Schottky in glass, about 0.4 V at 10 mA.
1N5711	0.41 V @ 1 mA	0.033 A	50 V		2 pF	DO-35	4	higher forward drop. Low-capacitance 70 V Schottky with very low leakage, but only 33 mA average current.
BAT85S	0.24 V @ 0.1 mA	0.2 A	30 V	5 ns	10 pF	DO-35	2	Very low-drop glass Schottky: 0.24 V at 0.1 mA, 0.32 V at 1 mA.
BAT41	0.4 V @ 1 mA	0.1 A	100 V		2 pF	DO-35	113	higher forward drop. About 0.4 V at 1 mA, close to a germanium clipping drop with far lower leakage.
1N5819	0.6 V @ 1000 mA	1 A	40 V		110 pF	DO-41	61	DO-41
1N5818	0.55 V @ 1000 mA	1 A	30 V		125 pF	DO-41	42	DO-41
1N5817	0.45 V @ 1000 mA	1 A	20 V		125 pF	DO-41	4236	20 V reverse; DO-41. Vf is specified only at 1 A and above, so the sheet says nothing about the low clipping knee.
B5817WS-TP	0.45 V @ 1000 mA	1 A	20 V	50 ns	80 pF	SOD-323	2	20 V reverse; SOD-323. Surface-mount 1N5817 equivalent for polarity protection; leakage is high (up to 200 µA at 20 V).
