ISL9012IRNJZ Equivalent & Substitute Parts

Part Overview

The ISL9012IRNJZ 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 classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the ISL9012IRNJZ is determined by the following critical parameters:

Package Compatibility: All substitutes must use the 10-VFDFN Exposed Pad (3x3) surface mount package to ensure PCB layout compatibility
Output Configuration: Dual positive fixed output regulators with matching voltage rails and current delivery specifications
Electrical Performance: Input voltage rating (6.5V max), dropout voltage characteristics, quiescent current, and protection feature set
Compliance Standards: RoHS3 compliance and REACH unaffected status for regulatory alignment

Two substitute parts meet these criteria within the ISL9012 product family from Renesas Electronics Corporation.

Engineering Selection Recommendations

ISL9012IRNNZ: This part is an active product with identical electrical specifications to the main part except for the second output voltage (3.3V instead of 2.8V) and improved dropout voltage at 300mA (0.325V vs 0.4V). Selection is appropriate when the circuit design can accommodate dual 3.3V outputs. The higher moisture sensitivity level (MSL 3) requires controlled storage conditions during manufacturing.

ISL9011AIRNJZ: This part provides parametric equivalence with matching output voltages (3.3V, 2.8V) and dropout voltage characteristics identical to the main part. As an active product, it offers long-term availability and supply continuity. The higher moisture sensitivity level (MSL 3) applies the same storage requirements as ISL9012IRNNZ.

Both substitutes maintain full compliance with RoHS3 and REACH requirements, ensuring regulatory alignment with the original part.

Frequently Asked Questions (FAQ)

Q: Can ISL9012IRNNZ replace ISL9012IRNJZ in all applications?

A: ISL9012IRNNZ is electrically compatible for applications requiring dual 3.3V outputs. If your design specifically requires one 2.8V output and one 3.3V output, this part is not suitable. The improved dropout voltage at 300mA (0.325V vs 0.4V) may provide marginal performance benefits in low-input-voltage scenarios.

Q: What is the difference between ISL9011AIRNJZ and ISL9012IRNJZ?

A: ISL9011AIRNJZ provides parametric equivalence with identical output voltages and dropout voltage specifications. The primary difference is product status: ISL9012IRNJZ is obsolete while ISL9011AIRNJZ is active. Both use the same 10-VFDFN package and share identical electrical performance characteristics.

Q: Are there packaging differences between these parts?

A: All three parts use the 10-VFDFN Exposed Pad (3x3) surface mount package. The main part (ISL9012IRNJZ) is supplied in standard packaging, while ISL9012IRNNZ and ISL9011AIRNJZ are supplied in tube packaging. PCB footprint and reflow soldering requirements are identical.

Q: What does Moisture Sensitivity Level (MSL) 3 mean for manufacturing?

A: MSL 3 indicates the component must be stored in controlled humidity conditions (≤60% RH) and has a floor life of 168 hours after exposure to ambient conditions. Proper moisture barrier packaging and bake-out procedures are required before assembly. MSL 1 (unlimited) parts like the main ISL9012IRNJZ have no such restrictions.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes, all three parts share identical 10-VFDFN package dimensions and pinout. PCB layout and footprint design require no modification. Schematic changes are necessary only if switching from ISL9012IRNJZ to ISL9012IRNNZ due to the different second output voltage (3.3V vs 2.8V).
