Substitution Feasibility Conclusion
In applications that do not require automotive-grade or high-reliability specifications, the 2SCR502U3T106 can directly replace the 2SCR502U3HZGT106. However, if the design targets automotive electronics or explicitly calls for AEC-Q101 qualification, substitution is not permissible.
Comparison Points
1. Product Grade and Qualification: The part number 2SCR502U3HZGT106 is explicitly marked with “Grade: Automotive” and “Qualification: AEC-Q101,” whereas these designations are absent from the parameter list of the 2SCR502U3T106. The HZGT106 variant is an AEC-Q101 qualified automotive-grade device. Its manufacturing flow, test standards, and reliability have undergone additional verification and control to meet the harsh environmental demands of automotive applications, such as temperature cycling, high temperature/high humidity, and long-term operational life. The T106 version is an industrial/commercial standard product and has not undergone this specific qualification.
2. Cost and Supply Chain: The HZGT106 carries a higher price ($0.50000 vs. $0.44000). This premium reflects the additional qualification costs, more stringent testing, and expenses associated with meeting automotive supply chain traceability requirements. The T106 version offers a cost advantage and is suitable for cost-sensitive projects without mandatory qualification requirements.
