Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer verification. Confirm the specific suffix E6433 matches project requirements, as packaging variants may exist. Check for end-of-life status or discontinuation notices prior to finalizing procurement plans to ensure long-term supply availability.

Selection Notes

Select this component when a PNP digital transistor with 50 V breakdown and 100 mA current capability is required. The 10 kOhm input resistance suits standard logic levels. Ensure the SOT-323-3 footprint aligns with the board layout. Compare against similar BCR series parts if different resistor ratios or NPN polarity are needed.

Part Context

This part belongs to Infineon's BCR series of digital transistors, which combine bipolar junction transistors with integrated biasing resistors. The series provides standardized solutions for switching and amplification tasks, reducing external component requirements compared to discrete transistor configurations.

Replacement Considerations

Publicly confirmed substitutes include the BCR185WH6327XTSA1. Verify pinout compatibility and electrical parameters before substitution.
