Key Parameters

Substitute Part Grouping Explanation

Substitution analysis for the ISL62392HRTZ is based on the following critical parameters:

• Functional category: Power Management (PMIC) / Power Supply Controller
• Supply voltage compatibility: 5.5V ~ 25V operating range
• Current consumption: 150 µA
• Mounting technology: Surface Mount preferred for modern designs
• Package form factor: 28-pin configuration
• Environmental compliance: RoHS3 compliance required

The identified substitute part SG1548J operates within compatible voltage parameters (4.5V ~ 35V supply range) and shares the same functional category as a Power Supply Monitor. However, this substitute exhibits significant differences in mounting type, package configuration, and current consumption characteristics that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The SG1548J presents limited direct substitution capability for the ISL62392HRTZ due to fundamental design differences:

Compliance Considerations: The ISL62392HRTZ maintains ROHS3 compliance, while the SG1548J is RoHS non-compliant. This distinction is critical for applications subject to environmental regulations and procurement standards requiring compliant components.

Mounting and Package Differences: The ISL62392HRTZ uses surface mount technology in a 28-TQFN package, while the SG1548J employs through-hole mounting in a 16-CDIP package. These differences necessitate significant PCB redesign and are not suitable for direct pin-compatible replacement.

Current Consumption: The SG1548J draws 4.8 mA compared to the ISL62392HRTZ at 150 µA, representing a 32-fold increase in supply current. This parameter difference impacts power budget calculations and thermal management requirements.

Voltage Range Compatibility: While the SG1548J supports a wider supply voltage range (4.5V ~ 35V), the ISL62392HRTZ operates within a narrower 5.5V ~ 25V window. The substitute's extended lower voltage limit does not provide functional advantage for notebook computer applications.

Frequently Asked Questions (FAQ)

Q: Can the SG1548J directly replace the ISL62392HRTZ on existing PCBs?

A: No. The SG1548J uses through-hole mounting in a 16-CDIP package, while the ISL62392HRTZ is a surface mount 28-TQFN device. Direct PCB replacement is not possible without complete circuit redesign.

Q: What are the key differences in electrical performance?

A: The primary electrical differences are supply current consumption (150 µA vs. 4.8 mA) and operating temperature range (-10°C ~ 100°C vs. -55°C ~ 125°C). The SG1548J also supports a wider input voltage range (4.5V ~ 35V vs. 5.5V ~ 25V).

Q: Is the SG1548J suitable for new designs requiring RoHS compliance?

A: No. The SG1548J is RoHS non-compliant, making it unsuitable for applications requiring environmental compliance certification. The ISL62392HRTZ maintains ROHS3 compliance.

Q: Why is the ISL62392HRTZ in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing this product line. Customers requiring this component should secure inventory during the available window before production ends.

Q: What functional differences exist between these parts?

A: The ISL62392HRTZ is classified as a Power Supply Controller, while the SG1548J functions as a Power Supply Monitor. These represent different functional roles within power management architectures.
