Key Parameters

Substitute Part Grouping Explanation

The AP7345D-2833RH4-7 qualifies as a direct substitute based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Identical output voltage configuration: 2.8V and 3.3V fixed dual outputs
• Identical maximum input voltage: 5.25V
• Identical voltage dropout specifications: 0.3V @ 300mA, 0.29V @ 300mA
• Identical output configuration: Positive fixed
• Identical operating temperature range: -40°C ~ 85°C
• Identical control features: Enable function
• Identical compliance: ROHS3 Compliant, REACH Unaffected
• Same manufacturer: Diodes Incorporated
• Same base product family: AP734x series

Enhanced Specifications: The AP7345D-2833RH4-7 provides increased current capacity (300mA per channel versus 150mA) and upgraded package (8-pin X2-DFN1612-8 versus 6-pin X2-DFN1212-6), making it suitable for applications requiring higher current delivery while maintaining full backward compatibility in voltage and control specifications.

Engineering Selection Recommendations

The AP7345D-2833RH4-7 is the recommended substitute for the AP7342D-2833FS6-7 based on the following engineering criteria:

Product Status Alignment: The AP7345D-2833RH4-7 maintains Active product status, ensuring continued availability and manufacturing support, whereas the AP7342D-2833FS6-7 is in Last Time Buy status with limited future supply.

Compliance Continuity: Both parts maintain identical ROHS3 compliance and REACH Unaffected status, ensuring regulatory requirements are preserved across the substitution.

Electrical Compatibility: The substitute part maintains all critical voltage specifications (2.8V and 3.3V outputs, 5.25V maximum input) and identical dropout characteristics, ensuring functional equivalence in existing circuit designs.

Enhanced Capability: The increased current capacity (300mA versus 150mA per channel) and additional protection features (Short Circuit protection) provide design margin without requiring circuit modifications.

Package Consideration: The larger 8-pin package (X2-DFN1612-8) requires PCB layout adjustment but provides improved thermal performance and current handling capability.

Frequently Asked Questions (FAQ)

Q: Can the AP7345D-2833RH4-7 directly replace the AP7342D-2833FS6-7 without circuit modifications?

A: Electrical substitution is direct due to identical output voltages, input voltage ratings, and control specifications. However, the package change from 6-pin to 8-pin requires PCB layout modification. The larger package footprint and additional pins must be accommodated in the design.

Q: What are the key differences between these two parts?

A: The primary differences are output current capacity (150mA versus 300mA per channel), package size (6-pin versus 8-pin), and protection features. The AP7345D-2833RH4-7 includes Short Circuit protection and Current Limit control, while the AP7342D-2833FS6-7 provides Over Current protection.

Q: Is the AP7345D-2833RH4-7 suitable for applications originally designed for the AP7342D-2833FS6-7?

A: Yes, provided the application's current requirements do not exceed 150mA per channel. The substitute part's higher current rating (300mA) is backward compatible with lower-current designs. PCB layout must be updated to accommodate the different package.

Q: What is the impact of the higher quiescent current in the AP7345D-2833RH4-7?

A: The quiescent current increases from 100 µA to 140 µA. This 40 µA difference is negligible in most applications but should be evaluated in battery-powered or ultra-low-power designs where every microamp matters.

Q: Are both parts available in the same packaging format?

A: No. The AP7342D-2833FS6-7 uses X2-DFN1212-6 (6-pin), while the AP7345D-2833RH4-7 uses X2-DFN1612-8 (8-pin). Both are surface-mount packages with exposed pads, but the footprints differ and require separate PCB designs.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both parts are ROHS3 Compliant, REACH Unaffected, and rated for -40°C to 85°C operating temperature. Moisture Sensitivity Level is identical at MSL 1 (Unlimited) for both parts.
