Key Parameters

Substitute Part Grouping Explanation

The MCP1700T-1802E/MB from Microchip Technology is identified as a substitute based on the following substitution criteria:

Electrical Compatibility Parameters:

• Fixed output voltage of 1.8V matches the primary part requirement
• Input voltage maximum of 6V is compatible with the AP7365-18YG-13 specification
• Package type TO-243AA (SOT-89-3) provides mechanical and pinout compatibility
• Both parts feature Over Current and Over Temperature protection

Substitution Limitations: The MCP1700T-1802E/MB has a maximum output current of 200mA, which is lower than the AP7365-18YG-13 specification of 600mA. This part is suitable only for applications where the required load current does not exceed 200mA.

Parameter Comparison

Engineering Selection Recommendations

Both the AP7365-18YG-13 and MCP1700T-1802E/MB are Active status products with ROHS3 compliance and REACH unaffected designation. Selection between these parts is determined by load current requirements:

AP7365-18YG-13 is the primary choice for applications requiring output currents up to 600mA with the specified electrical characteristics.

MCP1700T-1802E/MB is suitable as a substitute only when the application load current does not exceed 200mA. This part offers advantages including lower quiescent current (4 µA vs 80 µA), lower dropout voltage at its rated current (0.35V vs 0.6V), extended operating temperature range (-40°C to 125°C vs -40°C to 85°C), and additional short circuit protection.

Both parts are Surface Mount devices in identical TO-243AA (SOT-89-3) packages, ensuring mechanical compatibility in PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can MCP1700T-1802E/MB replace AP7365-18YG-13 in all applications?

A: No. The MCP1700T-1802E/MB is limited to 200mA output current. It is suitable only for applications where the load current requirement does not exceed 200mA. For applications requiring 600mA output current, the AP7365-18YG-13 must be used.

Q: Are the packages mechanically compatible?

A: Yes. Both parts use the TO-243AA package (SOT-89-3), providing identical pinout and mechanical compatibility for Surface Mount PCB assembly.

Q: What are the key electrical differences?

A: The primary difference is output current capability: AP7365-18YG-13 provides 600mA while MCP1700T-1802E/MB provides 200mA. Secondary differences include quiescent current (80 µA vs 4 µA), dropout voltage at rated current (0.6V vs 0.35V), and PSRR specifications (65dB at 1kHz vs 44dB at 100Hz).

Q: Are both parts RoHS compliant?

A: Yes. Both AP7365-18YG-13 and MCP1700T-1802E/MB are ROHS3 compliant and REACH unaffected.

Q: What is the operating temperature difference?

A: AP7365-18YG-13 operates from -40°C to 85°C, while MCP1700T-1802E/MB operates from -40°C to 125°C. The MCP1700T-1802E/MB provides extended high-temperature operation capability.
