Substitute Part Grouping Explanation

Substitute parts for the AP7361-18E-13 are qualified based on the following criteria:

Primary Substitution Criteria:

Fixed output voltage of 1.8V
SOT-223-3 package compatibility
Surface-mount mounting type
Active product status
RoHS3 compliance
Maximum input voltage of 6V or greater

Secondary Compatibility Factors:

Engineering Selection Recommendations

Direct Equivalents (1A Output Current):

MIC37100-1.8WS and MIC37100-1.8WS-TR are direct functional equivalents to the AP7361-18E-13, both delivering 1A output current at 1.8V in SOT-223-3 packaging. Both parts maintain active product status and RoHS3 compliance. The primary difference is packaging format: MIC37100-1.8WS is supplied in Tube packaging, while MIC37100-1.8WS-TR is supplied in Tape & Reel format. Both feature improved voltage dropout performance (0.5V @ 1A versus 0.7V @ 1A) and extended operating temperature range to 125°C. Selection between these two depends on procurement and assembly requirements.

Alternative with Reduced Output Current (800mA):

TC1264-1.8VDBTR provides 800mA output current, suitable for applications requiring less than 1A. This part maintains 1.8V output voltage, SOT-223-3 package compatibility, and active product status with RoHS3 compliance. The voltage dropout specification is higher at 1.4V @ 800mA. This part is appropriate only when the application load current does not exceed 800mA.

Alternative with Significantly Reduced Output Current (300mA):

MCP1824ST-1802E/DB delivers 300mA output current at 1.8V in SOT-223-3 packaging. This part is suitable only for low-power applications with load currents not exceeding 300mA. It features the lowest voltage dropout (0.32V @ 300mA) and includes Under Voltage Lockout (UVLO) protection in addition to standard protections. Active product status and RoHS3 compliance are maintained.

Frequently Asked Questions (FAQ)

Q: Can MIC37100-1.8WS-TR be used as a direct replacement for AP7361-18E-13?

A: Yes. Both parts deliver 1A output current at 1.8V in SOT-223-3 packaging with identical input voltage specifications (6V maximum). Pin configuration and package footprint are compatible. The MIC37100-1.8WS-TR features lower voltage dropout (0.5V versus 0.7V) and extended temperature range to 125°C. Both are active products with RoHS3 compliance.

Q: What is the difference between MIC37100-1.8WS and MIC37100-1.8WS-TR?

A: Both parts are electrically identical with 1A output current at 1.8V. The difference is packaging format: MIC37100-1.8WS is supplied in Tube packaging, while MIC37100-1.8WS-TR is supplied in Tape & Reel format. Selection depends on assembly line requirements and procurement preferences.

Q: Can TC1264-1.8VDBTR replace AP7361-18E-13 in all applications?

A: No. TC1264-1.8VDBTR is limited to 800mA output current. It is suitable only for applications where the load current does not exceed 800mA. The higher voltage dropout (1.4V @ 800mA) may also affect performance in applications with tight voltage margin requirements.

Q: Can MCP1824ST-1802E/DB replace AP7361-18E-13?

A: No. MCP1824ST-1802E/DB is limited to 300mA output current and is suitable only for low-power applications. It cannot support the full 1A output current of the AP7361-18E-13.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are RoHS3 compliant and maintain active product status, matching the regulatory compliance of the AP7361-18E-13.

Q: What is the operating temperature difference between AP7361-18E-13 and its substitutes?

A: The AP7361-18E-13 operates from -40°C to 85°C. All substitute parts extend the maximum operating temperature to 125°C, providing improved thermal margin in high-temperature environments. The minimum operating temperature of -40°C is maintained across all parts.
