It integrates a 10 kOhms base resistor (R1) between the base and the input pin, so you can drive it directly from a microcontroller or logic output without an external series resistor. The 150 MHz transition frequency keeps switching clean for low-speed digital loads like relay coils, indicator LEDs, and small-signal level shifting.
Infineon lists the BCR 179F E6327 as obsolete. If this line is still in your BOM, you are looking at the surplus and independent-distribution channel.
There is no factory production or last-time-buy window remaining. Sourcing is through surplus and independent-distribution channels only.
Infineon does not list an official successor for the BCR 179F E6327. A functionally similar part would be a PNP pre-biased transistor in SOT-723 with a 10 kOhm base resistor, 50 V VCEO, and 100 mA IC rating. The base resistor value and package footprint are the two parameters to match exactly — the rest of the specs (hFE, fT, saturation voltage) are typical for this class. Check the Infineon BCR 135 series or NXP PDTC series for candidates, but verify the pinout and marking against your board.
The BCR 179F is the base product number for the family. The 'E6327' suffix is Infineon's ordering code for the tape-and-reel packaging variant. Electrically and mechanically, the BCR 179F E6327 is identical to other BCR 179F variants — the suffix only specifies the reel quantity and packaging format.
