Procurement Notes

This component is officially marked as obsolete and no longer manufactured by Infineon Technologies. Verification of availability should focus on authorized distributors holding remaining stock or approved replacement part numbers. Ensure that any sourced units match the original specification requirements before integration into designs.

Selection Notes

Engineers replacing this part must consider the discontinuation status when selecting alternatives. Key parameters such as the 60mA output current, 18V maximum input voltage, and SOT-143R package footprint should be matched. Verify that substitute components maintain AEC-Q100 qualification if the application requires automotive compliance.

Part Context

The BCR401 series represents Infineon's line of integrated LED drivers. This specific model utilizes a dedicated current source topology rather than complex PWM dimming features found in other variants. It serves as a simple, robust solution for driving single-channel LEDs where precise current control is required without additional external components.
