Package compatibility: Both utilize TO-220-3 package configuration, enabling direct PCB footprint compatibility.

Compliance matching: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements.

Product status consideration: The MC7912BTG is active production status, providing long-term availability and supply chain stability compared to the obsolete SCD7912BTG.

Parameter Comparison

Engineering Selection Recommendations

The MC7912BTG is the appropriate substitute for the obsolete SCD7912BTG. Both components share onsemi manufacturing origin, identical functional specifications for negative 12V regulation at 1A output, and compatible TO-220 package footprints. The MC7912BTG offers the additional advantage of active production status, ensuring supply chain continuity and availability for current and future applications.

Both parts maintain equivalent regulatory compliance with ROHS3 certification and REACH unaffected status, satisfying environmental and safety requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can MC7912BTG directly replace SCD7912BTG in existing designs? A: Yes. Both parts share identical TO-220 package configuration, negative 12V output specification, and 1A current rating. PCB footprints and pin configurations are compatible.

Q: What is the primary reason for substitution? A: The SCD7912BTG is obsolete. The MC7912BTG is in active production, providing reliable long-term supply availability.

Q: Are there compliance differences between these parts? A: No. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting equivalent regulatory requirements.

Q: What are the key electrical parameters that define substitution eligibility? A: Output voltage (-12V fixed), output current (1A), package type (TO-220), and manufacturer (onsemi) are the primary parameters determining substitution compatibility.

Q: Is thermal management different between these parts? A: The MC7912BTG specifies operating temperature range of -40°C to 125°C and includes over-temperature protection. Thermal design considerations remain consistent with TO-220 package specifications.
