Key Parameters

Substitute Part Grouping Explanation

Substitution of the AP7342D-1833FS6-7 is determined by the following critical parameters:

• Dual-output linear regulator topology with fixed 1.8V and 3.3V outputs
• Positive output configuration
• Minimum current capability per channel (150mA baseline)
• Maximum input voltage tolerance (5.25V)
• Operating temperature range (-40°C ~ 85°C)
• Surface mount packaging with exposed pad design
• RoHS3 compliance and MSL Level 1 rating

The AP7345D-1833RH4-7 qualifies as a direct substitute because it maintains the same output voltage configuration, input voltage specification, operating temperature range, and compliance certifications. The substitute part provides enhanced current capability (300mA per channel) and improved package density (8-pin X2-DFN1612-8), making it suitable for applications requiring equal or greater current delivery.

Parameter Comparison

Engineering Selection Recommendations

The AP7345D-1833RH4-7 is the qualified substitute for the AP7342D-1833FS6-7. Selection between these parts depends on application current requirements:

• Use AP7342D-1833FS6-7 for designs requiring exactly 150mA per output channel with minimal board space and lower quiescent current consumption.
• Use AP7345D-1833RH4-7 for designs requiring 150mA to 300mA per output channel, or where future design margin is necessary. This part is in Active production status, ensuring long-term availability.

Both parts maintain identical output voltage specifications, input voltage tolerance, operating temperature range, and regulatory compliance (ROHS3, MSL Level 1). The substitute part's larger package footprint accommodates the enhanced current capability and additional control features (Current Limit, Short Circuit protection vs. Over Current protection).

Frequently Asked Questions (FAQ)

Q: Can AP7345D-1833RH4-7 directly replace AP7342D-1833FS6-7 in existing designs?

A: Yes, provided the application current requirements do not exceed 300mA per channel and the PCB layout accommodates the larger 8-pin X2-DFN1612-8 package. Pin configuration and output voltage specifications are compatible.

Q: What are the key differences between these parts?

A: The primary differences are output current capability (150mA vs. 300mA per channel), package size (6-pin vs. 8-pin), quiescent current (100 µA vs. 140 µA), and product status (Last Time Buy vs. Active). Output voltages, input voltage tolerance, and thermal specifications remain identical.

Q: Why is AP7342D-1833FS6-7 in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer has discontinued production planning for this part number. The AP7345D-1833RH4-7 represents the active product line continuation with enhanced specifications.

Q: Are there package compatibility concerns when substituting?

A: Yes. The AP7345D-1833RH4-7 uses an 8-pin X2-DFN1612-8 package compared to the 6-pin X2-DFN1212-6 of the original part. PCB footprint, trace routing, and thermal pad design must be updated accordingly. Both packages feature exposed pads for thermal management.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both parts are ROHS3 compliant, carry MSL Level 1 rating (Unlimited moisture sensitivity), and share identical ECCN (EAR99) and HTSUS classifications.
