Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SC4486S-AN is determined by alignment of the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Transistor Type: NPN configuration
• Voltage Rating: Maximum collector-emitter breakdown voltage of 50V or greater
• Current Rating: Maximum collector current of 2A or greater
• Power Dissipation: Sufficient thermal capability for the application

Mechanical Compatibility Criteria:

• Mounting Type: Through-hole configuration
• Package Classification: Compatible lead geometry and pin count

Regulatory and Compliance Criteria:

• Moisture Sensitivity Level: MSL 1 or equivalent
• REACH Status: REACH Unaffected or compliant
• ECCN Classification: EAR99 or equivalent

The 2SD1801S-E meets these substitution criteria through matching NPN type, 50V voltage rating, 2A current rating, through-hole mounting, and equivalent regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 2SD1801S-E serves as a functional substitute for the 2SC4486S-AN based on the following engineering criteria:

Electrical Equivalence: Both components are NPN transistors with identical maximum voltage (50V) and current (2A) ratings. The 2SD1801S-E provides additional specification detail including saturation voltage, collector cutoff current, DC current gain, and transition frequency, all of which support the electrical requirements of applications originally designed for the 2SC4486S-AN.

Regulatory Compliance: Both parts maintain REACH Unaffected status and EAR99 ECCN classification, ensuring equivalent compliance posture. Both carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating no special handling requirements.

Product Status Consideration: Both the main part and substitute are classified as obsolete. Selection of the 2SD1801S-E should be based on current inventory availability and long-term supply chain viability. The 2SD1801S-E currently maintains higher inventory levels (15,100 pieces) compared to the 2SC4486S-AN (4,100 pieces).

Package Consideration: The 2SC4486S-AN uses SC-71 packaging, while the 2SD1801S-E uses TO-251-3 Short Leads (IPak) packaging. Physical board layout modifications may be required to accommodate the different package geometry.

Frequently Asked Questions (FAQ)

Q: Can the 2SD1801S-E directly replace the 2SC4486S-AN without circuit modifications?

A: Both transistors share identical maximum voltage (50V) and current (2A) ratings and are both NPN type. However, the different package types (SC-71 versus TO-251-3) require physical board layout changes. Electrical circuit operation is compatible based on the provided specifications.

Q: What are the key electrical parameters that determine substitution compatibility?

A: The critical parameters are transistor type (NPN), maximum collector-emitter voltage (50V minimum), maximum collector current (2A minimum), and mounting type (through-hole). Both the 2SC4486S-AN and 2SD1801S-E meet these criteria.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts maintain identical REACH Unaffected status, EAR99 ECCN classification, and MSL 1 moisture sensitivity levels. No additional compliance considerations apply to substitution.

Q: Why does the 2SD1801S-E have more detailed specifications than the 2SC4486S-AN?

A: The 2SC4486S-AN input data does not include detailed electrical parameters such as saturation voltage, current gain, or transition frequency. The 2SD1801S-E provides these specifications. Both parts are classified as obsolete, and specification availability may vary based on historical documentation.

Q: What should be considered when selecting between these parts?

A: Primary considerations are current inventory availability, package compatibility with existing board designs, and long-term supply chain viability. The 2SD1801S-E currently has higher inventory levels. Package differences require board layout evaluation.

Q: Are there other substitutes listed for the 2SD1801S-E?

A: The 2SD1802S-E is identified as a substitute for the 2SD1801S-E. Evaluation of that part would require separate analysis against the substitution criteria.
