ISL9012IRGCZ-T Equivalent & Substitute Parts

Part Overview

The ISL9012IRGCZ-T is a linear voltage regulator IC manufactured by Renesas Electronics Corporation, designed for positive fixed dual-output applications. This device integrates two independent regulators capable of delivering 150mA and 300mA outputs at fixed voltages of 2.7V and 1.8V respectively. The part is classified as obsolete, necessitating identification of active alternative components that maintain functional and electrical compatibility for new designs and production continuity.

Substitute Part Grouping Explanation

Substitution of the ISL9012IRGCZ-T is determined by the following critical parameters:

Dual-output positive fixed voltage regulator topology
Output voltage levels: 2.7V and 1.8V (or compatible alternatives within application tolerance)
Current delivery capability: 150mA and 300mA per output
Maximum input voltage rating of 5.5V or higher
Voltage dropout characteristics suitable for the application input range
10-pin DFN/MLF package footprint compatibility
Surface mount technology
Protection features: Over current and over temperature protection
Operating temperature range: -40°C minimum to 85°C minimum

The MIC2214-JGYML-TR qualifies as a substitute based on matching dual-output topology, compatible output current ratings, package footprint compatibility, and surface mount configuration.

Engineering Selection Recommendations

The MIC2214-JGYML-TR is an active substitute for the obsolete ISL9012IRGCZ-T. Both devices maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new production.

Key considerations for substitution:

The MIC2214-JGYML-TR output voltage for the first regulator is 2.5V instead of 2.7V. Circuit design must accommodate this voltage difference or confirm application tolerance.
Maximum input voltage is reduced from 6.5V to 5.5V. Input supply design must remain within the 5.5V limit.
Quiescent current is doubled (80 µA vs. 40 µA), affecting power consumption in standby conditions.
Dropout voltage increases at 300mA output (0.42V vs. unspecified for original), requiring verification of minimum input voltage headroom.
The substitute lacks soft start and UVLO protection features present in the original. Application circuits must evaluate whether these protections are critical to system function.
Operating temperature maximum extends to 125°C, providing broader thermal operating range.

Frequently Asked Questions (FAQ)

Q: Can the MIC2214-JGYML-TR directly replace the ISL9012IRGCZ-T in existing designs?

A: Direct replacement requires circuit validation. The 2.5V output (vs. 2.7V) and reduced maximum input voltage (5.5V vs. 6.5V) must be confirmed compatible with the application. Absence of soft start and UVLO protection features must be evaluated for system requirements.

Q: What is the primary difference in output voltage between these parts?

A: The ISL9012IRGCZ-T provides 2.7V and 1.8V outputs. The MIC2214-JGYML-TR provides 2.5V and 1.8V outputs. The 1.8V output is identical; the first output differs by 0.2V.

Q: Are the packages physically compatible?

A: Both devices are available in 10-pin DFN/MLF packages with 3x3mm footprints and exposed pads. PCB footprints are compatible for surface mount assembly.

Q: Why is the quiescent current higher in the substitute?

A: The MIC2214-JGYML-TR draws 80 µA quiescent current compared to 40 µA in the ISL9012IRGCZ-T. This difference affects standby power consumption and must be evaluated in battery-powered or low-power applications.

Q: What protection features are lost in substitution?

A: The MIC2214-JGYML-TR omits soft start and under-voltage lockout (UVLO) protection. The original device includes these features. Applications relying on these protections require circuit-level alternatives or design modification.

Q: Is the substitute suitable for high-temperature applications?

A: The MIC2214-JGYML-TR operates to 125°C maximum, exceeding the original 85°C limit. This provides advantage for elevated-temperature environments.

Q: What compliance certifications apply to both parts?

A: Both the ISL9012IRGCZ-T and MIC2214-JGYML-TR are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.
