AP7365-12YG-13 Equivalent & Substitute Parts

Part Overview

The AP7365-12YG-13 is a linear voltage regulator IC from Diodes Incorporated designed for positive fixed output applications. This Surface Mount device delivers 600mA output current at a fixed 1.2V output with a maximum dropout voltage of 0.6V at full load. The part is currently in Active product status with 1789 units available in inventory.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or when design requirements permit operation within the electrical parameters of alternative devices. The AP7217D-12YG-13 is identified as a parametric equivalent with comparable functional characteristics.

Parameter Comparison

Engineering Selection Recommendations

AP7365-12YG-13 is the primary selection for new designs and applications requiring active product status with extended supply availability. This part offers superior electrical performance with lower dropout voltage (0.6V vs. 1.3V) and higher PSRR (65dB vs. 55dB), making it suitable for noise-sensitive applications and designs with tighter input voltage margins.

AP7217D-12YG-13 is applicable only when the AP7365-12YG-13 is unavailable and the application can tolerate the following conditions: reduced maximum input voltage (5.5V instead of 6V), increased dropout voltage (1.3V instead of 0.6V), and lower PSRR performance (55dB instead of 65dB). This part carries Last Time Buy status, indicating limited future availability. Moisture sensitivity level 3 (168 hours) requires controlled storage conditions compared to level 1 for the primary part.

Both parts maintain identical output voltage, output current, operating temperature range, package format, and protection features, ensuring mechanical and thermal compatibility in existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can AP7217D-12YG-13 be used as a direct replacement for AP7365-12YG-13?

A: Mechanical and thermal compatibility is confirmed due to identical SOT-89-3 packaging and Surface Mount mounting type. Electrical compatibility depends on application requirements. The AP7217D-12YG-13 has a lower maximum input voltage (5.5V vs. 6V) and higher dropout voltage (1.3V vs. 0.6V). Applications operating near 6V input or requiring low dropout performance must use the AP7365-12YG-13.

Q: What is the impact of the 0.7V dropout voltage difference?

A: The AP7217D-12YG-13 requires 0.7V additional headroom above the 1.2V output voltage to maintain regulation at 600mA. For a 5V input supply, the AP7365-12YG-13 maintains regulation with 3.4V margin, while the AP7217D-12YG-13 maintains regulation with 2.7V margin. Applications with input voltages below 2.5V cannot use the AP7217D-12YG-13.

Q: What does Last Time Buy status mean for the AP7217D-12YG-13?

A: Last Time Buy indicates the manufacturer will not produce additional units beyond current inventory. The 2190 units currently available represent the final supply. New designs should not incorporate this part. Existing designs using this part should transition to the AP7365-12YG-13 during the next design revision.

Q: Are there differences in moisture handling between these parts?

A: The AP7365-12YG-13 has Moisture Sensitivity Level 1 (unlimited shelf life under controlled conditions). The AP7217D-12YG-13 has Moisture Sensitivity Level 3 (168-hour floor life after bag opening). The AP7217D-12YG-13 requires more stringent moisture control during storage and assembly processes.

Q: How do the PSRR specifications affect circuit performance?

A: PSRR (Power Supply Rejection Ratio) measures the regulator's ability to reject input voltage noise. The AP7365-12YG-13 provides 65dB rejection at 1kHz, while the AP7217D-12YG-13 provides 55dB rejection. The 10dB difference represents approximately 3.16x better noise rejection on the AP7365-12YG-13. Applications with noisy input supplies or sensitive analog circuits benefit from the higher PSRR of the primary part.

Q: Can both parts be used interchangeably in inventory?

A: No. The different packaging formats (Tape & Reel for AP7365-12YG-13 vs. Cut Tape & Digi-Reel® for AP7217D-12YG-13) require different handling in automated assembly equipment. Separate inventory management and feeder configurations are necessary.
