Engineering Selection Recommendations

The AP7345D-3030RH4-7 is the manufacturer-recommended substitute for the AP7342D-3030FS6-7. Selection of this substitute is supported by the following factors:

Both parts maintain identical output voltage specifications (3V, 3V)
Both operate within the same input voltage range (maximum 5.25V)
Both comply with ROHS3 and maintain MSL 1 classification
The AP7345D-3030RH4-7 carries Active product status, ensuring long-term availability and supply chain stability
The substitute provides doubled output current capability (300mA vs. 150mA per channel), offering design flexibility for current-limited applications
Package transition from 6-pin to 8-pin XFDFN requires PCB layout modification but maintains surface mount compatibility
Both devices operate across the identical temperature range (-40°C to 85°C)

The AP7342D-3030FS6-7 remains a parametric equivalent to itself, maintaining all original specifications for applications where the exact part number is required.

Frequently Asked Questions (FAQ)

Q: Can the AP7345D-3030RH4-7 directly replace the AP7342D-3030FS6-7 without circuit modifications?

A: The AP7345D-3030RH4-7 provides the same output voltages and input voltage tolerance. However, the package changes from 6-pin to 8-pin XFDFN, requiring PCB layout redesign. Pin configuration must be verified against the respective datasheets before implementation.

Q: What is the primary difference between these two parts?

A: The main difference is output current capability. The AP7342D-3030FS6-7 provides 150mA per output channel, while the AP7345D-3030RH4-7 provides 300mA per output channel. The substitute also includes additional control features (Current Limit) and enhanced protection (Short Circuit vs. Over Current).

Q: Why is the AP7342D-3030FS6-7 marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer is discontinuing this part. The AP7345D-3030RH4-7, with Active status, is the recommended path forward for new designs and ongoing production.

Q: Are there compliance differences between the main part and substitute?

A: Both parts maintain identical RoHS3 compliance and MSL 1 classification. REACH and ECCN designations are equivalent across both parts.

Q: What PCB considerations apply when switching from AP7342D-3030FS6-7 to AP7345D-3030RH4-7?

A: The package footprint changes from 6-XFDFN to 8-XFDFN. The exposed pad remains present in both packages. Pin count increases from 6 to 8, requiring verification of pin assignments and potential routing adjustments on the PCB.
