Frequently Asked Questions

Q: Is the 2SB186 suitable for modern circuit designs?
A: The 2SB186 is primarily designed for vintage equipment restoration. For new designs, consider modern silicon alternatives like the BC557 or 2N3906 PNP transistors.

Q: What is the complementary NPN germanium transistor?
A: The complementary NPN germanium transistor is the 2SA186, which pairs with the 2SB186 in complementary circuits.

Notes

Germanium transistor – vintage/NOS stock. Characteristics differ significantly from modern silicon transistors (higher leakage current, temperature sensitivity). Ideal for authentic restoration only.

Note: Price refers to one (1) piece. The component is shipped in bulk without individual packaging.
