3sk41 Datasheet ~repack~

| Part Number | Compatibility Notes | Availability | | :--- | :--- | :--- | | | Nearly identical pinout (SOT-103). Superior noise figure (2dB). Drop-in with adapter. | Scarce | | BF998 | Surface mount (SOT-143). Higher transconductance. Requires a breakout board. | Common | | 3SK74 | Direct Japanese equivalent. Same TO-72 package. Perfect for vintage restorations. | Rare | | MPF121 | American equivalent, but higher capacitance. Not ideal above 150 MHz. | Obsolete | | Dual-gate 40673 | Metal can. Higher VDS tolerance but lower gain. Works as a slow substitute. | Obsolete |

: In many circuits, it can be part of a broader series of "3SK" transistors (like the 3SK35 or 3SK40) depending on the specific voltage and gain requirements of your project. Jotrin Electronics Are you looking to use this for a new RF design 3SK41 - NEC/HITACHI/MOTOROLA - Jotrin 3sk41 datasheet
