Procurement Notes
This component has been officially declared obsolete by the manufacturer as of November 24, 2020. Verification of availability requires checking authorized distributors for remaining stock or identifying qualified replacement parts from the same product family. Ensure that any substitute components meet the original electrical specifications and package dimensions to maintain design integrity.
Selection Notes
Designers should evaluate the ACS102-6T1-TR as a potential functional replacement due to similar ratings and packaging. Verify that the substitute part maintains compatibility with the existing PCB footprint and thermal management requirements. Confirm that the gate trigger characteristics of the alternative device align with the microcontroller output capabilities to ensure reliable switching performance.
Part Context
The ACS302 series belongs to STMicroelectronics' AC switch family, which integrates triac functionality with protection features. These devices utilize ASD technology to provide high noise immunity and eliminate the need for external snubber networks. The series is engineered to simplify circuit designs by reducing component count while ensuring compliance with electromagnetic interference standards.
Replacement Considerations
The ACS102-6T1-TR is listed as a similar replacement part. Verify pinout compatibility and confirm that the replacement meets the required 600 V and 400 mA specifications before implementation.
