Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AP7342D-2825FS6-7 is determined by the following critical parameters:

• Output voltage configuration (2.5V and 2.8V fixed outputs required)
• Dual-output positive regulator topology
• Maximum input voltage rating (5.25V or higher)
• Operating temperature range (-40°C ~ 85°C minimum)
• RoHS3 compliance and regulatory status
• Surface mount packaging compatibility

The AP7345D-2825RH4-7 qualifies as a manufacturer-recommended substitute. While this part increases output current capability to 300mA per channel and transitions to an 8-pin package, it maintains the core electrical specifications, output voltage configuration, input voltage rating, temperature range, and compliance certifications required for functional equivalence in the AP7342D-2825FS6-7 application space.

Parameter Comparison

Engineering Selection Recommendations

The AP7345D-2825RH4-7 is the manufacturer-recommended substitute for the AP7342D-2825FS6-7. Selection of this substitute is supported by:

• Active product status, ensuring continued availability and supply chain stability
• Identical output voltage configuration and input voltage specifications
• Matching operating temperature range and thermal performance envelope
• ROHS3 compliance and equivalent regulatory certifications
• Enhanced current delivery capability (300mA vs. 150mA per channel) providing design margin for existing and future applications
• Identical PSRR performance for noise-sensitive applications

PCB layout modifications are required due to package transition from 6-pin to 8-pin XFDFN. Thermal and electrical performance remain equivalent or superior to the original part.

Frequently Asked Questions (FAQ)

Q: Can the AP7345D-2825RH4-7 directly replace the AP7342D-2825FS6-7 without design changes?

A: Electrical substitution is direct. The output voltages, input voltage rating, operating temperature range, and control features are compatible. However, the package changes from 6-XFDFN to 8-XFDFN, requiring PCB layout modifications including footprint redesign and trace routing adjustments.

Q: What are the key differences between these parts?

A: The AP7345D-2825RH4-7 provides doubled output current (300mA vs. 150mA per channel), additional current limit control feature, and short circuit protection versus over current protection. Quiescent current increases from 100 µA to 140 µA. Both parts maintain identical output voltages, input voltage specifications, and operating temperature ranges.

Q: Are both parts RoHS compliant?

A: Yes. Both the AP7342D-2825FS6-7 and AP7345D-2825RH4-7 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Why is the AP7342D-2825FS6-7 in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer has discontinued production planning. The AP7345D-2825RH4-7, with Active status, represents the current production alternative and ensures long-term design support.

Q: What thermal considerations apply to the substitute part?

A: Both parts operate across -40°C ~ 85°C. The AP7345D-2825RH4-7 features an 8-pin package with exposed pad, providing equivalent or improved thermal dissipation compared to the 6-pin original design.
