as a close relative. Other similar dual-gate MOSFETs in the 3SK family include: Often interchangeable in many RF circuits. 3SK80 / 3SK81: Related MOS field-effect transistors. Modern Alternatives: For new designs, surface-mount parts like the

Many listings on eBay or Aliexpress selling "3SK41" are actually remarked BF245 or 2N5486 JFETs. If the pinout measures like a diode (P-N junction), it is a fake. A real 3SK41 will measure open circuit between all pins when tested with a multimeter's diode setting (except source-to-drain when body diode conducts). 3sk41 Datasheet

Converting high-frequency signals to intermediate frequencies (IF). Oscillators: Found in Colpitts and Hartley RF oscillator designs. Cross-Reference & Equivalents as a close relative

The 3SK41 is built for high gain and low noise, making it effective for sensitive receiver front-ends. Silicon N-Channel Dual-Gate MOSFET. Typically found in a (four-pin) metal package. Frequency Range: Modern Alternatives: For new designs

If your 3SK41 datasheet shows V_G2S = 4V for 20mS, but your BF998 datasheet shows V_G2S = 2V for the same gain, simply adjust the G2 voltage divider (replace a 47k with a 100k) to supply 2V instead of 4V.
