ISL9012IRNFZ Equivalent & Substitute Parts

Part Overview

The ISL9012IRNFZ is a linear voltage regulator IC from Renesas Electronics Corporation designed for power management applications. This dual-output positive fixed regulator delivers 150mA and 300mA outputs with integrated protection features including over-current, over-temperature, soft start, and under-voltage lockout. The device is currently classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity.

Parameter Comparison

Engineering Selection Recommendations

ISL9012IRNNZ is a direct substitute for applications requiring dual 3.3V outputs. This part maintains identical electrical specifications for input voltage, output current, quiescent current, and protection features. The primary difference is the second output voltage configuration (3.3V instead of 2.5V). This part carries active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. The MSL rating of 3 (168 Hours) requires standard moisture control during storage and handling.

ISL9011AIRNFZ is a parametric equivalent suitable for applications requiring the original 3.3V/2.5V dual-output configuration. This part maintains identical voltage output specifications and dropout characteristics as the ISL9012IRNFZ. Active product status provides superior supply chain continuity compared to the obsolete main part. The MSL rating of 3 (168 Hours) applies standard moisture sensitivity protocols. The ISL9011 base product number indicates a related but distinct device family within the Renesas linear regulator portfolio.

Both substitute parts satisfy all mandatory electrical and mechanical parameters. Selection between them depends on specific output voltage requirements: ISL9012IRNNZ for dual 3.3V applications, ISL9011AIRNFZ for 3.3V/2.5V dual-output applications.

Frequently Asked Questions (FAQ)

Q: Can ISL9012IRNNZ replace ISL9012IRNFZ in all applications?

A: ISL9012IRNNZ is suitable only for applications where both output voltages can operate at 3.3V. If your design requires one output at 2.5V, this substitute is not compatible. Verify your circuit's voltage requirements before substitution.

Q: What is the difference between ISL9012IRNNZ and ISL9011AIRNFZ?

A: Both parts maintain the same electrical performance and package specifications. ISL9012IRNNZ provides dual 3.3V outputs, while ISL9011AIRNFZ provides 3.3V and 2.5V outputs. The ISL9011 represents a different base product number within the Renesas regulator family. Selection depends on your specific output voltage configuration needs.

Q: Are the substitute parts pin-compatible with ISL9012IRNFZ?

A: Both substitute parts use the 10-VFDFN Exposed Pad package (10-DFN 3x3), which is mechanically and electrically compatible. PCB layout and footprint remain unchanged.

Q: What does MSL 3 (168 Hours) mean for ISL9012IRNNZ and ISL9011AIRNFZ?

A: Moisture Sensitivity Level 3 indicates the component must be stored in controlled humidity conditions and used within 168 hours of opening the moisture barrier bag. Standard moisture control procedures apply during handling and assembly.

Q: Why is ISL9012IRNFZ marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. Active substitute parts (ISL9012IRNNZ and ISL9011AIRNFZ) provide equivalent functionality with ongoing manufacturing support and supply availability.

Q: Do all three parts have identical protection features?

A: Yes. All three parts include over-current, over-temperature, soft start, and under-voltage lockout (UVLO) protection. Protection performance is equivalent across all variants.

Q: Are there any compliance differences between the main part and substitutes?

A: All three parts are ROHS3 compliant and REACH unaffected. Regulatory compliance is equivalent across all variants.
