Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SCD7815CTG is determined by strict equivalence across the following critical parameters:

• Output voltage: 15V fixed
• Output current capacity: 1A
• Input voltage maximum: 35V
• Package type: TO-220-3
• Mounting configuration: Through Hole
• Output configuration: Positive fixed regulation
• Operating temperature range: 0°C ~ 125°C
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The MC7815CTG from onsemi meets all these criteria and serves as a direct substitute. Both devices share identical electrical specifications for voltage regulation, current handling, and thermal operating range. The primary distinction is product status: MC7815CTG is active production, whereas SCD7815CTG is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The MC7815CTG is the appropriate selection for applications currently using or specifying the SCD7815CTG. Both devices are manufactured by onsemi and maintain identical electrical and thermal specifications. The MC7815CTG carries active product status with established supply chain availability (158,550 pcs in stock versus 905 pcs for the obsolete SCD7815CTG), ensuring long-term procurement reliability.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications. The TO-220-3 package remains consistent across both devices, permitting direct board-level substitution without layout modifications.
