Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS563202DRLR is determined by strict alignment of the following critical parameters:

Functional Equivalence Requirements:

• Topology: Buck (step-down) switching regulator
• Output Configuration: Positive adjustable
• Number of Outputs: Single output
• Output Current Rating: 3A minimum
• Synchronous Rectifier: Present

Electrical Compatibility Requirements:

• Input Voltage Range: Must encompass or exceed 4.3V to 17V
• Output Voltage Range: Must support 0.806V to 7V adjustability
• Package Type: SOT-563 or SOT-666 surface mount

Compliance Requirements:

• RoHS3 Compliance: Required
• MSL Rating: 1 (Unlimited) preferred
• Product Status: Active

The AP62300Z6-7 manufactured by Diodes Incorporated meets all functional, electrical, and compliance criteria for substitution. Both devices share identical output current capacity, package form factors, and regulatory compliance status. Differences in switching frequency (750kHz vs. 580kHz), input voltage maximum (18V vs. 17V), and operating temperature range represent acceptable variations within the substitution scope.

Engineering Selection Recommendations

TPS563202DRLR Selection Criteria:

• Applications requiring extended operating temperature range up to 125°C junction temperature
• Industrial and high-reliability environments where Texas Instruments qualification is specified
• Designs with input voltage specifications at or below 17V maximum
• Standard commercial-grade applications with active product availability

AP62300Z6-7 Selection Criteria:

• Automotive and AEC-Q100 qualified applications requiring automotive-grade components
• Designs benefiting from higher input voltage tolerance (up to 18V)
• Applications where lower minimum input voltage (4.2V) provides operational advantage
• Systems where higher switching frequency (750kHz) reduces external component size
• Automotive supply chain integration or OEM specifications requiring Diodes Incorporated qualification

Both parts maintain active product status, ROHS3 compliance, and unlimited moisture sensitivity level ratings. The AP62300Z6-7 carries AEC-Q100 automotive qualification, making it suitable for automotive applications where the TPS563202DRLR may not meet qualification requirements. Selection between these parts depends on application-specific temperature requirements, automotive qualification necessity, and input voltage operating range.

Frequently Asked Questions (FAQ)

Q: Can the AP62300Z6-7 directly replace the TPS563202DRLR in all applications?

A: Direct replacement is possible for applications operating within the AP62300Z6-7 temperature range (-40°C to 85°C ambient). Applications requiring junction temperatures above 85°C or designs leveraging the TPS563202DRLR's 125°C maximum junction temperature require thermal analysis to confirm compatibility. Both devices share identical output current, package form factor, and adjustable output voltage range.

Q: What is the significance of the different switching frequencies (580kHz vs. 750kHz)?

A: The AP62300Z6-7 operates at 750kHz compared to the TPS563202DRLR's 580kHz. Higher switching frequency reduces the size of external filtering components (inductors and capacitors) but may increase switching losses. Circuit design and component selection must account for this frequency difference. Both frequencies are within standard buck regulator operating ranges.

Q: Are the SOT-563 and SOT-666 packages interchangeable between these parts?

A: Both the TPS563202DRLR and AP62300Z6-7 are available in SOT-563 and SOT-666 packages. These packages are mechanically and electrically compatible for surface mount assembly. Verify the specific package variant (SOT-563 or SOT-666) required for your PCB layout and assembly process.

Q: What does AEC-Q100 qualification mean for the AP62300Z6-7?

A: AEC-Q100 is an automotive electronics qualification standard. The AP62300Z6-7 meets this qualification, making it suitable for automotive applications. The TPS563202DRLR does not carry this automotive qualification. If your application requires automotive-grade components, the AP62300Z6-7 is the appropriate selection.

Q: How do the input voltage ranges differ between these parts?

A: The TPS563202DRLR operates from 4.3V to 17V input. The AP62300Z6-7 operates from 4.2V to 18V input. The AP62300Z6-7 provides a lower minimum input voltage (0.1V lower) and higher maximum input voltage (1V higher). For applications operating near these limits, verify the specific part meets your input voltage requirements.

Q: Are there packaging differences between Cut Tape and Tape & Reel formats?

A: The TPS563202DRLR is supplied in Cut Tape (CT) and Digi-Reel® formats. The AP62300Z6-7 is supplied in Tape & Reel (TR) format. These represent different packaging and delivery methods for surface mount components. Cut Tape is suitable for smaller quantities and manual assembly, while Tape & Reel is optimized for automated pick-and-place assembly. Packaging format does not affect electrical or mechanical compatibility.

Q: What is the minimum output voltage difference between these parts?

A: The TPS563202DRLR minimum output voltage is 0.806V, while the AP62300Z6-7 minimum is 0.8V. This 0.006V difference is negligible for most applications. Both parts support adjustable output voltage up to 7V using external resistor networks.

Q: Can I use the AP62300Z6-7 in a design originally specified for the TPS563202DRLR?

A: Substitution is possible if your application operates within the AP62300Z6-7's specifications: ambient temperature to 85°C, input voltage 4.2V to 18V, and output current to 3A. If your original design requires the extended temperature range or specific Texas Instruments qualification, substitution is not appropriate. Consult application-specific requirements and thermal analysis before substitution.
