ISL9000AIRBCZ Equivalent & Substitute Parts

Part Overview

The ISL9000AIRBCZ is a linear voltage regulator IC manufactured by Renesas Electronics Corporation, designed for positive fixed dual-output applications. This device integrates two independent 300mA regulators with fixed output voltages of 1.5V and 1.8V in a compact 10-DFN (3x3) surface mount package. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations where this topology is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISL9000AIRBCZ is determined by the following critical parameters:

• Dual-output linear regulator topology with independent channels
• Fixed output voltage levels of 1.5V and 1.8V
• Output current capability of 300mA per channel
• Surface mount packaging in 10-pin DFN form factor
• Positive output configuration
• Control features including Enable and Power On Reset functionality
• Protection against over-current, over-temperature, and under-voltage conditions
• RoHS3 compliance and MSL Level 1 rating

The MIC2211-FGYML-TR from Microchip Technology meets these core substitution criteria, offering equivalent dual-output fixed voltage regulation with compatible package geometry and protection features.

Parameter Comparison

Engineering Selection Recommendations

The MIC2211-FGYML-TR is an active product from Microchip Technology and represents a viable substitute for the obsolete ISL9000AIRBCZ. Both devices share identical fixed output voltage specifications (1.5V and 1.8V), dual-regulator architecture, and equivalent package footprints suitable for surface mount assembly.

Key considerations for selection:

The MIC2211-FGYML-TR operates with a maximum input voltage of 5.5V compared to the ISL9000AIRBCZ at 6.5V. Applications requiring input voltages above 5.5V will require circuit redesign or alternative component selection.

The first output channel of the MIC2211-FGYML-TR is rated for 150mA versus 300mA on the ISL9000AIRBCZ. Load requirements exceeding 150mA on the 1.5V output necessitate design verification.

The MIC2211-FGYML-TR exhibits higher quiescent current consumption at 80 µA compared to 32 µA for the ISL9000AIRBCZ, impacting standby power budgets in battery-powered applications.

The MIC2211-FGYML-TR provides an extended operating temperature range to 125°C versus 85°C maximum for the ISL9000AIRBCZ, offering improved thermal margin in high-temperature environments.

Both devices maintain RoHS3 compliance and MSL Level 1 moisture sensitivity ratings, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the MIC2211-FGYML-TR directly replace the ISL9000AIRBCZ in existing designs?

A: Direct replacement is possible only when the application input voltage does not exceed 5.5V and the 1.5V output current requirement does not exceed 150mA. The 1.8V output supports 300mA on both devices. PCB layout compatibility should be verified due to potential differences in package pin assignments between manufacturers.

Q: What are the primary differences affecting substitution?

A: The maximum input voltage specification differs (6.5V versus 5.5V), the first output channel current rating differs (300mA versus 150mA), and quiescent current consumption is higher on the substitute part (80 µA versus 32 µA). The MIC2211-FGYML-TR lacks under-voltage lockout protection present on the ISL9000AIRBCZ.

Q: Are both devices available in the same package?

A: Both devices use 10-pin DFN packages with 3x3mm footprints. The ISL9000AIRBCZ uses 10-VFDFN while the MIC2211-FGYML-TR uses 10-MLF®. Physical dimensions are compatible, but pin-to-pin verification is required before PCB implementation.

Q: What compliance certifications apply to both parts?

A: Both the ISL9000AIRBCZ and MIC2211-FGYML-TR are RoHS3 compliant, REACH unaffected, classified under ECCN EAR99, and carry HTSUS code 8542.39.0001. Both maintain MSL Level 1 moisture sensitivity ratings.

Q: Is the MIC2211-FGYML-TR suitable for applications requiring the full 300mA on both outputs simultaneously?

A: No. The MIC2211-FGYML-TR is limited to 150mA on the first output channel. Applications requiring 300mA on both channels must retain the ISL9000AIRBCZ or identify alternative dual-output regulators with matching current specifications.
