Key Parameters

Substitute Part Grouping Explanation

Substitution of the AP7346D-2825FS6-7 is determined by the following critical parameters:

• Dual-output configuration with fixed positive voltage regulation
• Output voltage levels: 2.5V and 2.8V
• Minimum current delivery capability: 130mA per channel
• Maximum input voltage: 5.25V
• Dropout voltage performance: 0.3V @ 120mA or better
• Surface mount packaging with exposed pad design
• Operating temperature range: -40°C ~ 85°C
• RoHS3 compliance and MSL Level 1 rating

The AP7345D-2825RH4-7 qualifies as a manufacturer-recommended substitute. While this part operates at higher current levels (300mA per channel) and uses a different package footprint (8-XFDFN vs. 6-XFDFN), it maintains electrical compatibility across all critical parameters including output voltages, input voltage limits, dropout performance, and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

The AP7345D-2825RH4-7 is the manufacturer-recommended substitute for the AP7346D-2825FS6-7. Both devices maintain identical electrical specifications for output voltage, input voltage limits, and operating temperature range. The substitute part is currently in Active product status, ensuring long-term availability and supply chain stability compared to the Last Time Buy status of the original part.

The primary design consideration is package footprint change from 6-XFDFN to 8-XFDFN. This requires PCB layout modification but does not affect electrical performance. The substitute part's higher current capability (300mA vs. 130mA per channel) provides additional design margin without introducing compatibility issues.

Both parts maintain identical RoHS3 compliance and MSL Level 1 ratings, ensuring equivalent environmental and regulatory compliance for manufacturing and field deployment.

Frequently Asked Questions (FAQ)

Q: Can the AP7345D-2825RH4-7 directly replace the AP7346D-2825FS6-7 without circuit modification?

A: Electrical substitution is valid. The output voltages, input voltage specifications, dropout performance, and operating temperature ranges are identical. However, the package footprint differs (8-XFDFN vs. 6-XFDFN), requiring PCB layout redesign.

Q: What is the impact of the higher current rating on the AP7345D-2825RH4-7?

A: The substitute part delivers 300mA per channel versus 130mA on the original part. This provides additional current capacity and design margin. Applications requiring only 130mA per channel will operate within the substitute's specifications without adverse effects.

Q: Are there compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant with MSL Level 1 ratings. Regulatory compliance is equivalent across REACH, ECCN, and HTSUS classifications.

Q: Why is the original part in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing this product line. The AP7345D-2825RH4-7 represents the active alternative within the same product family.

Q: What are the quiescent current differences?

A: The AP7345D-2825RH4-7 has a quiescent current of 140 µA compared to 100 µA on the original part. This 40 µA difference is negligible in most applications and reflects the higher current capability of the substitute design.
