Engineering Selection Recommendations

The ISL9011AIRKKZ from Intersil is the primary equivalent substitute for the obsolete ISL9012IRKKZ. Both devices share identical electrical specifications, package footprint, and protection feature sets. The ISL9011AIRKKZ maintains active product status, ensuring long-term availability and supply chain continuity.

The MIC2214-NNYML-TR from Microchip Technology is a similar alternative with the following considerations: maximum input voltage is reduced to 5.5V (versus 6.5V), dropout voltage is higher at 0.25V and 0.42V, quiescent current is doubled to 80µA, and soft start protection is not included. The MIC2214-NNYML-TR offers an extended operating temperature range to 125°C and is available in both 10-VFDFN and 10-MLF® packages. Both substitute parts maintain ROHS3 compliance and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can the ISL9011AIRKKZ directly replace the ISL9012IRKKZ without design changes?

A: Yes. The ISL9011AIRKKZ is a parametric equivalent with identical output voltages (2.85V dual), current ratings (150mA and 300mA), dropout voltage specifications, quiescent current, and protection features. The 10-VFDFN package footprint is identical, enabling direct PCB substitution.

Q: What are the key differences between the MIC2214-NNYML-TR and the ISL9012IRKKZ?

A: The MIC2214-NNYML-TR has a lower maximum input voltage (5.5V versus 6.5V), higher dropout voltages (0.25V at 150mA and 0.42V at 300mA versus 0.2V and 0.325V), doubled quiescent current (80µA versus 40µA), and lacks soft start protection. It does provide an extended operating temperature range to 125°C.

Q: Are package footprints compatible across all three parts?

A: The ISL9012IRKKZ and ISL9011AIRKKZ use identical 10-VFDFN exposed pad packages (3x3mm). The MIC2214-NNYML-TR is available in both 10-VFDFN and 10-MLF® packages, both with the same 3x3mm footprint, ensuring PCB compatibility.

Q: What compliance certifications apply to these parts?

A: The ISL9012IRKKZ and MIC2214-NNYML-TR are ROHS3 compliant. All three parts are REACH unaffected and classified under ECCN EAR99 with HTSUS code 8542.39.0001.

Q: Which substitute is recommended for new designs?

A: The ISL9011AIRKKZ is recommended for new designs due to its parametric equivalence to the obsolete ISL9012IRKKZ and active product status. The MIC2214-NNYML-TR may be considered if the reduced maximum input voltage and higher dropout voltage specifications are acceptable for the application.
