Key Parameters

Substitute Part Grouping Explanation

Substitution of the AP7342D-3018FS6-7 is determined by the following critical parameters:

• Dual-output positive fixed voltage regulator configuration (1.8V and 3V outputs)
• Maximum input voltage of 5.25V
• Output current capability per channel
• Package form factor and pin compatibility
• Operating temperature range (-40°C ~ 85°C)
• Compliance certifications (ROHS3, REACH Unaffected)

The AP7345D-3018RH4-7 qualifies as a substitute based on matching output voltage levels, input voltage specifications, operating temperature range, and regulatory compliance. The substitute provides enhanced current output capability (300mA per channel versus 150mA), improved dropout voltage performance, and active product status, making it suitable for direct replacement in applications where the increased current capacity does not create thermal or design constraints.

Parameter Comparison

Engineering Selection Recommendations

The AP7345D-3018RH4-7 is the qualified substitute for the AP7342D-3018FS6-7. Both devices maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment. The substitute is currently in Active product status, providing long-term supply availability compared to the Last Time Buy status of the original part.

The primary design consideration is package footprint change from 6-pin X2-DFN1212-6 to 8-pin X2-DFN1612-8. PCB layout modifications are required to accommodate the larger package. The increased output current capability (300mA versus 150mA per channel) and improved dropout voltage characteristics of the substitute provide performance benefits for applications operating near the original part's current limits.

Frequently Asked Questions (FAQ)

Q: Can the AP7345D-3018RH4-7 directly replace the AP7342D-3018FS6-7 without design changes?

A: Direct pin-for-pin replacement is not possible due to package differences (6-pin versus 8-pin). PCB layout redesign is required. However, the electrical specifications are compatible for the same output voltage and input voltage requirements.

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

A: The substitute provides doubled output current per channel (300mA versus 150mA), improved dropout voltage performance, and active product status. The package size increases from X2-DFN1212-6 to X2-DFN1612-8, requiring PCB modifications.

Q: Are both parts compliant with the same regulatory standards?

A: Yes. Both the AP7342D-3018FS6-7 and AP7345D-3018RH4-7 are ROHS3 Compliant and REACH Unaffected, meeting equivalent regulatory requirements.

Q: Why is the original part marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer is discontinuing this product line. The AP7345D-3018RH4-7 represents the active replacement offering from Diodes Incorporated for continued design support and supply availability.

Q: Does the increased quiescent current of the substitute affect power consumption?

A: The quiescent current increase from 100 µA to 140 µA is minimal and typically negligible in most applications. The improved dropout voltage and higher output current capability of the substitute generally provide better overall system performance.

Q: What package considerations should be evaluated for substitution?

A: The substitute uses an 8-pin package versus the original 6-pin package. Verify PCB layout space availability, trace routing, and thermal management requirements for the larger X2-DFN1612-8 footprint before design implementation.
