SMT replacment for 2SK170/2SK389

[AudioAngel]

Hello!

Does anyone know, which device I should use for a replacment of the 2sk170/2sk389 with a SMT device?

Thanks,

Raphael

Hi,

there seem to be a couple of similar devices.
2SK879 - Toshiba, SC70 (lower gm, lower capacitance)
2SK880 - Toshiba, SC70 (lower gm, lower capacitance)
2SK932 - Sanyo, SC70 (higher gm, lower capacitance)
2SK2145 - Dual-SK880, Toshiba, SOT23-5(?) (lower gm, lower capacitance)
2SK2394 - Sanyo, SOT23 (higher gm, lower capacitance)
2SK3320 - Dual for diff-amp inputs - Toshiba, USV (lower gm, lower capacitance)
2SK3557- Sanyo, SC70 (higher gm, lower capacitance)

specialties:
CPH5901 - Sanyo, JFET-NPN-cascode (2Sk932/2SC4639)
CPH5902 - Sanyo, JFET-NPN-cascode (2Sk2394/2SC4639)
CPH5905 - Sanyo, JFET-NPN-cascode (2Sk3557/2SC4639)
IFN147 - Interfet, 2SK147 equivalent
IFN1801 - Interfet, very lownoise
IFN3601 - Interfet, extreme lownoise
