Parameter Comparison

Engineering Selection Recommendations

The TDA21460AUMA1 serves as the direct substitute for the obsolete TDA21460 based on shared base product number designation and identical regulatory compliance profiles. Both components maintain REACH Unaffected status and equivalent moisture sensitivity ratings, confirming compatibility in handling and environmental requirements.

The TDA21460AUMA1 is designated as "Not For New Designs," indicating it represents a transitional solution. For applications currently utilizing the TDA21460, the TDA21460AUMA1 provides functional continuity. The substitute specifies a 39-PowerVFQFN package with surface mount configuration, which must be verified against existing PCB layouts and assembly processes.

Selection between these parts should be based on inventory availability, application timeline, and design phase status. The TDA21460AUMA1 offers ROHS3 compliance, providing enhanced environmental standards compared to the base part specification.

Frequently Asked Questions (FAQ)

Q: Can TDA21460AUMA1 directly replace TDA21460 in existing designs?
