Substitute Part Grouping Explanation

The AP7345D-2518RH4-7 qualifies as a functional substitute based on the following alignment of critical electrical and mechanical parameters:

Substitution Criteria Met:

• Identical manufacturer (Diodes Incorporated)
• Identical output configuration (Positive, Fixed)
• Identical number of regulators (2)
• Identical output voltage levels (1.8V, 2.5V)
• Identical maximum input voltage (5.25V)
• Identical operating temperature range (-40°C ~ 85°C)
• Identical compliance certifications (ROHS3, REACH Unaffected, EAR99)
• Identical moisture sensitivity level (MSL 1 - Unlimited)

Key Differences:

• Output current capability increased from 150mA to 300mA per channel
• Package upgraded from 6-pin to 8-pin X2-DFN1612-8
• Voltage dropout characteristics improved at higher current levels
• Product status changed from Last Time Buy to Active

Parameter Comparison

Engineering Selection Recommendations

The AP7345D-2518RH4-7 is available as an active product with current manufacturing support, whereas the AP7342D-2518FS6-7 is designated Last Time Buy. Both devices maintain identical compliance certifications (ROHS3 Compliant, REACH Unaffected, EAR99 classification), ensuring regulatory equivalence.

Selection between these parts depends on application current requirements. The AP7342D-2518FS6-7 is suitable for designs requiring 150mA per output channel. The AP7345D-2518RH4-7 provides doubled output current capability (300mA per channel) and active product status, making it the preferred choice for new designs or applications requiring sustained supply availability.

Package footprint differences must be evaluated during PCB layout migration. The AP7345D-2518RH4-7 uses an 8-pin package versus the 6-pin package of the original part, requiring layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the AP7345D-2518RH4-7 directly replace the AP7342D-2518FS6-7 on existing PCBs?

A: Direct PCB replacement is not possible due to package differences. The AP7342D-2518FS6-7 uses a 6-pin X2-DFN1212-6 package, while the AP7345D-2518RH4-7 uses an 8-pin X2-DFN1612-8 package. PCB layout and routing modifications are required.

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

A: Yes. Both devices provide fixed dual outputs at 1.8V and 2.5V with identical maximum input voltage (5.25V) and operating temperature range (-40°C ~ 85°C).

Q: What is the primary functional difference between these regulators?

A: The AP7345D-2518RH4-7 provides 300mA per output channel compared to 150mA per channel on the AP7342D-2518FS6-7. The substitute also includes current limit control features and short circuit protection versus over current protection on the original part.

Q: Are both parts RoHS compliant?

A: Yes. Both the AP7342D-2518FS6-7 and AP7345D-2518RH4-7 are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Why is the AP7342D-2518FS6-7 marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer is discontinuing this product line. The AP7345D-2518RH4-7, maintained as an active product, represents the current generation equivalent with enhanced specifications.
