Substitute Part Grouping Explanation

The LM337BTG qualifies as a direct substitute for the SCD337BTG based on the following substitution criteria:

• Functional Classification: Both devices are negative adjustable linear voltage regulators within the Power Management (PMIC) category
• Output Capacity: Both deliver 1.5A maximum output current
• Packaging: Both utilize TO-220-3 package configuration
• Regulatory Compliance: Both maintain ROHS3 Compliant and REACH Unaffected status
• Trade Classification: Both share identical ECCN (EAR99) and HTSUS (8542.39.0001) codes
• Manufacturer Lineage: LM337BTG is the manufacturer-recommended successor from onsemi

The LM337BTG is an active product with documented electrical specifications, whereas the SCD337BTG is obsolete, making the LM337BTG the appropriate selection for new applications and production continuity.

Parameter Comparison

Engineering Selection Recommendations

The LM337BTG is the appropriate substitute for the obsolete SCD337BTG based on the following factors:

• Product Status Alignment: The LM337BTG maintains Active product status, ensuring ongoing availability and manufacturer support, whereas the SCD337BTG is Obsolete
• Regulatory Compliance: Both devices maintain identical ROHS3 Compliant and REACH Unaffected certifications, ensuring compliance with current environmental and safety standards
• Trade Classification Consistency: Identical ECCN and HTSUS codes confirm equivalent regulatory treatment for import/export and tariff purposes
• Functional Equivalence: Both devices are classified as negative adjustable linear regulators with 1.5A output capacity in TO-220 packaging

Selection of the LM337BTG eliminates obsolescence risk while maintaining full regulatory compliance and functional compatibility with existing designs.
