ISL9000AIRJCZ Equivalent & Substitute Parts

Part Overview

The ISL9000AIRJCZ is a linear voltage regulator IC from Renesas Electronics Corporation, classified as a Power Management (PMIC) device. This dual-output positive fixed regulator delivers 300mA per channel with output voltages of 1.8V and 2.8V, housed in a 10-DFN (3x3) surface mount package. The device is currently listed as obsolete, making identification of equivalent and substitute parts essential for design continuity and procurement planning. Active alternatives with identical or compatible electrical characteristics are available to support ongoing production and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISL9000AIRJCZ are identified based on strict electrical and mechanical compatibility criteria. The primary substitution logic is based on the following allowed parameters:

Parametric Equivalence Criteria:

• Identical output voltage configuration (1.8V and 2.8V dual outputs)
• Matching current delivery capability (300mA per output)
• Same input voltage rating (6.5V maximum)
• Identical package type (10-VFDFN Exposed Pad, 3x3)
• Matching control and protection features (Enable, Power On Reset, Over Current, Over Temperature, UVLO)
• Compatible operating temperature range (-40°C ~ 85°C)
• Same base product number (ISL9000 series)

Packaging Variation Allowance: Substitutes may differ in packaging format (Tube, Tape & Reel) as these represent distribution methods rather than functional differences. Moisture Sensitivity Level (MSL) variations are acceptable within the specified compliance framework.

Output Voltage Variation: The ISL9000AIRJBZ-T variant offers 1.5V and 2.8V outputs instead of 1.8V and 2.8V. This represents a functional variation in the lower output voltage and is classified as a similar substitute rather than a direct parametric equivalent.

Engineering Selection Recommendations

ISL9000AIRCJZ (Parametric Equivalent - Recommended Primary Substitute)

The ISL9000AIRCJZ is the direct parametric equivalent to the obsolete ISL9000AIRJCZ. Both devices deliver identical electrical performance with 1.8V and 2.8V dual outputs at 300mA per channel. The ISL9000AIRCJZ is currently in active production status, ensuring long-term availability and supply chain stability. Both parts maintain ROHS3 compliance and identical operating specifications across temperature, current, and protection parameters. The primary difference is packaging format (Tube) and MSL rating (3 vs. 1), which do not affect functional compatibility. This part is suitable for direct replacement in existing designs without circuit modification.

ISL9000AIRJBZ-T (Similar Substitute - Conditional Use)

The ISL9000AIRJBZ-T is an active alternative within the ISL9000 series with identical electrical performance except for the lower output voltage option (1.5V instead of 1.8V). This substitute is applicable only when the 1.5V output can replace the 1.8V requirement in the application circuit. The device maintains all other electrical characteristics, protection features, and compliance certifications. Packaging is supplied in Tape & Reel format with MSL rating of 1 (Unlimited), providing advantages for high-volume automated assembly. Selection of this part requires circuit-level verification that 1.5V operation is functionally acceptable.

Frequently Asked Questions (FAQ)

Q: Can ISL9000AIRCJZ be used as a direct replacement for ISL9000AIRJCZ?

A: Yes. The ISL9000AIRCJZ is a parametric equivalent with identical output voltages (1.8V, 2.8V), current ratings (300mA per output), input voltage specifications (6.5V max), and all control and protection features. The only differences are packaging format and MSL rating, which do not affect electrical functionality. No circuit modifications are required.

Q: What is the difference between ISL9000AIRJBZ-T and ISL9000AIRJCZ?

A: The ISL9000AIRJBZ-T provides 1.5V and 2.8V outputs, whereas the ISL9000AIRJCZ provides 1.8V and 2.8V outputs. All other electrical parameters, current ratings, protection features, and operating characteristics are identical. This substitute is suitable only if the application circuit can operate with 1.5V instead of 1.8V on the lower output.

Q: Why is the ISL9000AIRJCZ listed as obsolete?

A: The ISL9000AIRJCZ has been discontinued by Renesas Electronics Corporation. Active alternatives within the ISL9000 series (ISL9000AIRCJZ and ISL9000AIRJBZ-T) are available to support existing designs and new applications.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tube, Tape & Reel) represents the distribution and handling method only. The electrical specifications, performance characteristics, and functional behavior of the device remain identical regardless of packaging format.

Q: What does MSL rating mean, and does it affect substitution?

A: Moisture Sensitivity Level (MSL) indicates the maximum time a component can be exposed to moisture before soldering. MSL 1 (Unlimited) allows indefinite storage without moisture control, while MSL 3 (168 Hours) requires moisture control after 168 hours of exposure. For substitution purposes, MSL differences do not affect electrical compatibility but may impact storage and handling procedures. Verify your manufacturing environment requirements before selection.

Q: Are all three parts ROHS3 compliant?

A: Yes. ISL9000AIRJCZ, ISL9000AIRCJZ, and ISL9000AIRJBZ-T are all ROHS3 compliant, meeting environmental and regulatory requirements for lead-free manufacturing.

Q: Can I use ISL9000AIRJBZ-T in high-volume production?

A: Yes. The ISL9000AIRJBZ-T is supplied in Tape & Reel format, which is optimized for automated assembly processes in high-volume manufacturing. Verify that the 1.5V output specification is compatible with your circuit design before implementation.
