ISL9011AIRBCZ Equivalent & Substitute Parts

Part Overview

The ISL9011AIRBCZ is a linear voltage regulator IC manufactured by Renesas Electronics Corporation, designed for positive fixed dual-output applications with 150mA and 300mA output capabilities. This device integrates two independent regulators in a compact 10-DFN (3x3) package with integrated protection features including over-current, over-temperature, soft start, and under-voltage lockout functionality.

The ISL9011AIRBCZ is classified as obsolete. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production requirements for applications currently utilizing this regulator.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ISL9011AIRBCZ is determined by the following critical parameters:

• Dual positive fixed-output regulator configuration with 2 independent regulators
• Fixed output voltages of 1.5V and 1.8V
• Output current ratings of 150mA and 300mA per channel
• Enable control feature for power management
• Surface mount packaging in 10-pin DFN form factor
• ROHS3 compliance and MSL Level 1 rating

The MIC2211-FGYML-TR from Microchip Technology meets these core functional requirements. Both devices provide identical output voltage options, matching output current specifications, and equivalent control and protection architectures within the same physical package family.

Parameter Comparison

Engineering Selection Recommendations

The MIC2211-FGYML-TR is a direct functional substitute for the obsolete ISL9011AIRBCZ. Both devices are ROHS3 compliant with MSL Level 1 ratings, ensuring equivalent environmental and regulatory compliance for manufacturing and deployment.

The MIC2211-FGYML-TR offers extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 85°C), providing broader thermal performance margins. The substitute device specifies dropout voltage characteristics (0.25V @ 150mA, 0.42V @ 300mA), enabling precise power budget calculations. The maximum input voltage specification of 5.5V on the MIC2211-FGYML-TR is lower than the ISL9011AIRBCZ (6.5V); applications requiring input voltages above 5.5V require design verification.

The MIC2211-FGYML-TR has active product status, ensuring long-term availability and continued manufacturer support compared to the obsolete ISL9011AIRBCZ.

Frequently Asked Questions (FAQ)

Q: Can the MIC2211-FGYML-TR directly replace the ISL9011AIRBCZ in existing designs?

A: The MIC2211-FGYML-TR provides equivalent output voltage and current specifications with identical control features and package form factor. However, verify that your application input voltage does not exceed 5.5V, as the MIC2211-FGYML-TR has a lower maximum input voltage specification than the ISL9011AIRBCZ.

Q: What are the key differences between these two regulators?

A: The primary differences are: (1) Product status—MIC2211-FGYML-TR is active while ISL9011AIRBCZ is obsolete; (2) Maximum input voltage—5.5V versus 6.5V; (3) Quiescent current—80 µA versus 40 µA; (4) Operating temperature range—-40°C ~ 125°C versus -40°C ~ 85°C; (5) Protection features—MIC2211-FGYML-TR omits soft start and UVLO functions present in ISL9011AIRBCZ.

Q: Are both devices available in the same package?

A: Both devices use 10-pin DFN packages with exposed pads. The MIC2211-FGYML-TR is available in both 10-VFDFN and 10-MLF® variants, providing packaging flexibility for different manufacturing processes.

Q: What compliance certifications apply to both devices?

A: Both the ISL9011AIRBCZ and MIC2211-FGYML-TR are ROHS3 compliant, REACH unaffected, and classified as MSL Level 1 (unlimited moisture sensitivity). Both carry EAR99 export classification and HTSUS code 8542.39.0001.
