Substitute Part Grouping Explanation

Substitute parts for the AP1115BY30G-13 are classified based on the following substitution criteria:

MFR Recommended Substitute: AP7365-30YRG-13 qualifies as a manufacturer-recommended alternative. This part maintains the same fixed 3V output voltage, 600mA output current capability, and identical package format (SOT-89-3). The AP7365 series represents an active product line with improved electrical characteristics, including lower dropout voltage (0.4V vs. 1.3V) and significantly reduced quiescent current (80 µA vs. 10 mA).

Parametric Equivalent: AP1115BY30L-13 is a parametric equivalent sharing identical electrical specifications with the main part, including 18V maximum input voltage, 1.3V dropout voltage, and 10 mA quiescent current. The primary difference is packaging format (Cut Tape vs. Tape & Reel).

Cross-Manufacturer Alternative: MCP1703AT-3002E/MB from Microchip Technology provides a 3V fixed output in the same SOT-89-3 package. This part operates at a reduced output current rating of 250mA, making it suitable for lower-power applications within the 3V regulation requirement.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Active Product): AP7365-30YRG-13 is the preferred substitute when design specifications permit. This part is actively manufactured by Diodes Incorporated, ensuring long-term availability and supply chain stability. The improved electrical performance—particularly the 0.4V dropout voltage versus 1.3V—reduces power dissipation in applications with limited input voltage headroom. The reduced quiescent current (80 µA) benefits battery-powered or low-power standby applications. Note that the maximum input voltage is limited to 6V, which may restrict use in designs requiring the full 18V input range of the original part.

For Parametric Equivalence: AP1115BY30L-13 maintains identical electrical specifications to the AP1115BY30G-13, differing only in packaging format (Cut Tape versus Tape & Reel). This part is suitable when procurement requires alternative packaging but identical performance characteristics are mandatory.

For Lower Current Applications: MCP1703AT-3002E/MB from Microchip Technology provides an active alternative for designs requiring 250mA or less output current. This part offers superior quiescent current performance (5 µA) and extended operating temperature range (-40°C to 125°C), making it advantageous for low-power or wide-temperature applications. The reduced output current rating restricts this option to applications below 250mA.

Frequently Asked Questions (FAQ)

Q: Can AP7365-30YRG-13 replace AP1115BY30G-13 in all applications?

A: AP7365-30YRG-13 is compatible with applications where the input voltage does not exceed 6V. The original part supports up to 18V input. If your design requires input voltages above 6V, AP7365-30YRG-13 is not suitable. For applications within the 6V input limit, AP7365-30YRG-13 is a direct replacement with improved performance characteristics.

Q: What is the difference between AP1115BY30G-13 and AP1115BY30L-13?

A: These parts are parametrically identical in all electrical specifications. The difference is packaging format: AP1115BY30G-13 is supplied in Tape & Reel (TR), while AP1115BY30L-13 is supplied in Cut Tape (CT). Both are obsolete products from Diodes Incorporated.

Q: Can MCP1703AT-3002E/MB handle 600mA output current?

A: No. MCP1703AT-3002E/MB is rated for a maximum output current of 250mA. Applications requiring 600mA output current must use AP7365-30YRG-13 or AP1115BY30L-13. MCP1703AT-3002E/MB is suitable only for designs with output current requirements of 250mA or less.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. AP7365-30YRG-13, AP1115BY30L-13, and MCP1703AT-3002E/MB are all ROHS3 compliant, matching the compliance status of the original AP1115BY30G-13.

Q: What is the operating temperature range difference between substitutes?

A: AP1115BY30G-13 and AP1115BY30L-13 operate from 0°C to 125°C. AP7365-30YRG-13 operates from -40°C to 85°C, providing lower temperature capability but a reduced upper temperature limit. MCP1703AT-3002E/MB operates from -40°C to 125°C, providing the widest temperature range among all options.

Q: Does package format affect electrical performance?

A: No. Package format (Tape & Reel, Cut Tape, or SOT-89R-3) does not affect electrical performance. Format differences relate to supply and handling methods only. All parts in the same electrical series maintain identical performance within their rated specifications.
