Procurement Notes
Verify the manufacturer designation as Rochester Electronics, which typically handles surplus or obsolete components originally from Sanyo. Confirm the specific suffix 'E' matches the required pinout and thermal characteristics for your design. Ensure the component status is acceptable for your production timeline, as these parts may be classified as obsolete.
Selection Notes
Select this component when a high-power stereo Class AB solution is required with a maximum supply voltage up to 71.5V. It is suitable for designs needing 150W per channel at 6Ω impedance. Consider the 15-SIP through-hole package constraints and verify that the thermal management strategy supports the specified operating conditions.
Part Context
This part belongs to the STK433 series of audio power amplifier hybrids. The series includes variants with different power outputs, such as the STK433-040N-E and STK433-890N-E. These devices are designed for pin-to-pin compatibility within certain power ranges, allowing designers to scale output power while maintaining the same footprint and basic interface requirements.
Replacement Considerations
The STK433-060N-E and STK433-890N-E are listed as series models with similar form factors. Verify electrical ratings and pin configurations before substitution. No other direct substitute part numbers are confirmed in the provided documentation.
