• Surface mount packaging in SOT-89-3 or compatible footprint
• Operating temperature range of -40°C to 85°C
• Positive fixed output configuration
• Over current and over temperature protection features
• ROHS3 compliance

Two substitute parts meet these criteria and are listed below.

Parameter Comparison

Engineering Selection Recommendations

RT9166A-12GXL from Richtek USA Inc. is an active product with identical electrical specifications to the AP7217D-12YG-13, including matching output voltage, current rating, input voltage maximum, and operating temperature range. Both devices employ SOT-89-3 packaging, enabling direct footprint compatibility. The RT9166A-12GXL exhibits superior dropout voltage performance (0.58V typical versus 1.3V maximum) and maintains ROHS3 compliance. This part is recommended for applications requiring direct replacement with minimal design modification.

AP7361EA-12Y5-13 from Diodes Incorporated is an active product offering increased output current capability (1A versus 600mA) and improved dropout voltage characteristics (0.71V at 1A). This part includes additional short circuit protection and automotive-grade qualification (AEC-Q100). The package footprint differs (SOT-89-5 versus SOT-89-3), requiring PCB layout modification. This part is suitable for applications where increased current headroom or automotive compliance is beneficial.

Both substitute parts maintain ROHS3 compliance and operate across the required temperature range. Selection between them depends on packaging constraints and current requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can RT9166A-12GXL replace AP7217D-12YG-13 without PCB modification?

A: Yes. Both parts use SOT-89-3 packaging with identical pinout and footprint. Electrical specifications are compatible for applications requiring 600mA at 1.2V output.

Q: What is the primary advantage of AP7361EA-12Y5-13 over the main part?

A: AP7361EA-12Y5-13 provides 1A output current capacity compared to 600mA, lower dropout voltage (0.71V at 1A), and includes short circuit protection. It requires SOT-89-5 package accommodation on the PCB.

Q: Are both substitute parts suitable for industrial temperature applications?

A: Yes. Both RT9166A-12GXL and AP7361EA-12Y5-13 operate across -40°C to 85°C, matching the main part's temperature range.

Q: Do the substitute parts maintain regulatory compliance?

A: Yes. Both substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance status of AP7217D-12YG-13.

Q: Which substitute part has lower quiescent current consumption?

A: AP7361EA-12Y5-13 has quiescent current of 91 µA, compared to 300 µA for RT9166A-12GXL and 60 µA for the main part. For ultra-low power applications, the main part or AP7361EA-12Y5-13 are preferred.

Q: Can AP7361EA-12Y5-13 be used in applications designed for 600mA output?

A: Yes. AP7361EA-12Y5-13 is rated for 1A output, making it suitable for applications requiring 600mA or less. The higher current rating provides design margin without affecting performance at lower current levels.
