Key Parameters

Substitute Part Grouping Explanation

Substitution of the AP7342D-1528FS6-7 is determined by the following critical parameters:

• Output Configuration & Voltage Levels: Dual positive fixed outputs at 1.5V and 2.8V
• Current Capacity: Minimum 150mA per channel
• Input Voltage Range: Maximum 5.25V
• Package Type: Surface mount with exposed pad
• Control Features: Enable functionality
• Operating Temperature Range: -40°C to 85°C
• Compliance: ROHS3 compliant

The AP7345D-1528RH4-7 qualifies as a substitute because it maintains identical output voltage levels (1.5V, 2.8V), exceeds the current requirement (300mA vs. 150mA), operates within the same temperature range, and meets all compliance requirements. The higher current capacity and improved protection features (Short Circuit vs. Over Current) make this part suitable for applications requiring the same voltage outputs with enhanced current handling.

Parameter Comparison

Engineering Selection Recommendations

The AP7345D-1528RH4-7 is the manufacturer-recommended substitute for the AP7342D-1528FS6-7. Both devices are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The AP7345D-1528RH4-7 maintains active product status, ensuring long-term availability and supply chain stability compared to the Last Time Buy status of the original part.

The substitute provides doubled current capacity (300mA per output versus 150mA), making it suitable for applications requiring higher current delivery while maintaining identical output voltage specifications. The package transition from 6-pin to 8-pin X2-DFN format requires PCB layout modification but provides improved thermal performance and additional control features (Current Limit protection).

Frequently Asked Questions (FAQ)

Q: Can the AP7345D-1528RH4-7 directly replace the AP7342D-1528FS6-7 on existing PCBs?

A: No. The AP7345D-1528RH4-7 uses an 8-pin X2-DFN1612-8 package versus the 6-pin X2-DFN1212-6 package of the original part. PCB layout and footprint modifications are required.

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

A: The primary differences are current capacity (300mA vs. 150mA per output), package size (8-pin vs. 6-pin), quiescent current (140 µA vs. 100 µA), and protection features (Short Circuit vs. Over Current). Output voltages, input voltage range, and operating temperature remain identical.

Q: Are the output voltage levels identical between both parts?

A: Yes. Both the AP7342D-1528FS6-7 and AP7345D-1528RH4-7 provide fixed dual outputs of 1.5V and 2.8V with identical dropout voltage specifications.

Q: Why is the AP7345D-1528RH4-7 recommended as a substitute?

A: The AP7345D-1528RH4-7 is the manufacturer-recommended alternative because it maintains all critical electrical specifications (output voltages, input range, temperature range) while offering enhanced current capacity and active product status for continued availability.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and REACH unaffected. Both carry EAR99 ECCN classification and HTSUS code 8542.39.0001.
