Substitute Part Grouping Explanation

The AP7345D-3328RH4-7 qualifies as a manufacturer-recommended substitute based on the following substitution criteria:

Matching Parameters:

• Identical output voltage configuration: 2.8V and 3.3V dual fixed outputs
• Same input voltage maximum: 5.25V
• Identical output voltage types: Positive, Fixed
• Same number of regulators: 2
• Identical operating temperature range: -40°C ~ 85°C
• Same RoHS3 compliance and MSL rating
• Same manufacturer: Diodes Incorporated

Enhanced Specifications: The AP7345D-3328RH4-7 provides increased output current capability (300mA per channel versus 150mA), improved dropout voltage performance, and additional control features (Current Limit), making it a direct functional upgrade. The larger 8-pin X2-DFN1612-8 package accommodates the enhanced thermal and electrical requirements of the higher current rating.

Parameter Comparison

Engineering Selection Recommendations

The AP7345D-3328RH4-7 is the manufacturer-recommended substitute for the AP7342D-3328FS6-7. Both devices maintain ROHS3 compliance and identical MSL ratings, ensuring regulatory and environmental compatibility. The substitute part is in Active product status, providing long-term supply availability compared to the Last Time Buy status of the original part.

Selection of the AP7345D-3328RH4-7 is appropriate for applications where the increased output current capability (300mA versus 150mA per channel) does not create design constraints. The larger package footprint (8-pin versus 6-pin) must be accommodated in PCB layout. The enhanced protection features (Short Circuit versus Over Current) and additional control features (Current Limit) provide improved robustness in the substitute design.

Frequently Asked Questions (FAQ)

Q: Can the AP7345D-3328RH4-7 directly replace the AP7342D-3328FS6-7 on existing PCBs?

A: Direct PCB replacement is not possible due to package differences. The AP7342D uses a 6-pin X2-DFN1212-6 package, while the AP7345D uses an 8-pin X2-DFN1612-8 package. PCB layout redesign is required to accommodate the larger footprint and additional pins.

Q: Are the output voltage specifications identical between these parts?

A: Yes. Both parts provide fixed dual outputs at 2.8V and 3.3V with identical input voltage maximum of 5.25V and operating temperature range of -40°C to 85°C.

Q: What is the primary advantage of the AP7345D-3328RH4-7 over the AP7342D-3328FS6-7?

A: The AP7345D provides doubled output current capability (300mA per channel versus 150mA), improved dropout voltage characteristics at higher currents, and additional control features including Current Limit protection and Short Circuit protection.

Q: Are both parts RoHS compliant?

A: Yes. Both the AP7342D-3328FS6-7 and AP7345D-3328RH4-7 are ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: Why is the AP7342D-3328FS6-7 marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued production planning for this part. The AP7345D-3328RH4-7, maintained in Active status, is the recommended path forward for new designs and production continuity.
