| FFF Compatibility | Uses the same TO-220-3 package but has a mirrored pinout (Drain and Gate are swapped; Pin 1 is Drain, Pin 3 is Gate).Identical TO-220-3 physical package shape and dimensions.Identical electrical parameters (50V test, 115W output power, 1.8-250 MHz frequency range, 21.1 dB gain). | Uses a surface-mount SOT-1482-1 package instead of a through-hole TO-220-3.Completely different package size, mounting style (SMD vs Through-hole), and mechanical dimensions.Matches key electrical baseline parameters with 50V rating, 100W output power, and excellent gain characteristics. | ||
 AI Summary | MRF101AN by NXP USA Inc.: RF Mosfet 50 V 100 mA 1.8MHz ~ 250MHz 21.1dB 115W TO-220-3. | The MRF101BN is the mirrored-pinout sibling variant of the MRF101AN. It shares the same electrical specifications and TO-220-3 package, but because the Gate and Drain pins are swapped, it requires routing modifications to be used on an existing board. Since it is in the same family, it shares the same 'Last Time Buy' lifecycle risk.
| The BLP15H9S100Z offers an active-lifecycle, modern alternative from Ampleon designed for 50V RF power designs. Delivering 100W output power up to 1.5 GHz, it provides a highly reliable path forward for new or redesigned layouts, though it requires migrating from through-hole TO-220 to surface-mount SOT-1482-1.
