Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MC7906CT are identified based on strict electrical and mechanical parameter matching. The primary substitution criterion is functional equivalence across the following parameters: negative output configuration, fixed -6V output voltage, 1A output current capacity, TO-220-3 package format, and through-hole mounting compatibility. All substitute parts must maintain identical voltage regulation specifications, dropout characteristics, and thermal protection features. The MC7906CTG qualifies as a direct substitute based on complete parameter alignment with the main part, with the distinction that it carries active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The MC7906CTG is the direct equivalent substitute for the MC7906CT. Both parts share identical electrical specifications and mechanical packaging, ensuring pin-for-pin and functional compatibility. The MC7906CTG is preferred for new designs and procurement due to its active product status and ROHS3 compliance certification. The MC7906CT, classified as obsolete, should be replaced with MC7906CTG in applications where component availability and regulatory compliance are considerations. Both parts maintain equivalent performance across all specified electrical parameters, including output voltage regulation, current capacity, dropout voltage, and thermal protection characteristics.

Frequently Asked Questions (FAQ)
