ISL9011IRJCZ Equivalent & Substitute Parts

Part Overview

The ISL9011IRJCZ is a linear voltage regulator IC from Renesas Electronics Corporation designed for power management applications. This dual-output positive fixed regulator delivers 150mA and 300mA outputs with integrated protection features including over-current, over-temperature, soft start, and under-voltage lockout functionality. The device operates across a -40°C to 85°C temperature range and is housed in a 10-DFN (3x3) surface mount package with exposed pad.

The ISL9011IRJCZ is classified as obsolete. Identifying equivalent substitute parts is essential for design continuity, procurement flexibility, and long-term product support when original inventory becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISL9011IRJCZ are identified based on strict alignment with the following critical parameters:

Manufacturer compatibility: Same manufacturer (Renesas Electronics Corporation) ensures design continuity and consistent electrical characteristics.

Package equivalence: Identical 10-DFN (3x3) surface mount package with exposed pad ensures mechanical and thermal compatibility without PCB redesign.

Dual-output configuration: Both regulators must provide two independent outputs with fixed voltage regulation.

Output current capability: Substitute parts must deliver the same 150mA and 300mA output current ratings.

Input voltage rating: Maximum input voltage of 6.5V must be maintained.

Protection features: Over-current, over-temperature, soft start, and under-voltage lockout functionality must be present.

Operating temperature range: Full -40°C to 85°C operating range must be supported.

Compliance standards: RoHS3 compliance and REACH unaffected status required for regulatory alignment.

The ISL9011AIRJBZ meets all substitution criteria with one exception: the second output voltage is 1.5V instead of 1.8V. This voltage difference requires circuit-level evaluation to determine compatibility with existing designs.

Parameter Comparison

Engineering Selection Recommendations

The ISL9011AIRJBZ is an active product from the same manufacturer and represents the primary substitute for the obsolete ISL9011IRJCZ. Both devices share identical package geometry, electrical performance characteristics, and protection feature sets, enabling direct mechanical and thermal compatibility.

The critical distinction between these parts is the second output voltage specification: 1.8V for the ISL9011IRJCZ versus 1.5V for the ISL9011AIRJBZ. This 0.3V difference must be evaluated against circuit requirements. If the design tolerates 1.5V operation or includes downstream voltage regulation, the ISL9011AIRJBZ provides a viable path forward with the advantage of active product status and ongoing manufacturer support.

Both devices maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements. The ISL9011AIRJBZ carries a higher moisture sensitivity level (MSL 3 versus MSL 1), requiring adherence to 168-hour storage and handling protocols during manufacturing.

Frequently Asked Questions (FAQ)

Q: Can the ISL9011AIRJBZ directly replace the ISL9011IRJCZ without circuit modification?

A: Direct replacement is possible only if the circuit design tolerates a 1.5V output instead of 1.8V on the second regulator output. If the 1.8V specification is critical to circuit operation, design modification is required.

Q: Are the packages physically identical?

A: Yes. Both devices use the 10-VFDFN exposed pad package with identical 3x3mm dimensions and pin configuration. No PCB layout changes are necessary for mechanical compatibility.

Q: What is the impact of the different MSL ratings?

A: The ISL9011AIRJBZ has MSL 3 (168 hours) compared to MSL 1 (unlimited) for the ISL9011IRJCZ. This means the ISL9011AIRJBZ requires moisture control during storage and manufacturing. Devices must be baked before reflow soldering if storage exceeds 168 hours in standard humidity conditions.

Q: Why is the ISL9011IRJCZ obsolete?

A: The ISL9011IRJCZ is classified as obsolete by the manufacturer. The ISL9011AIRJBZ represents the active continuation of this product line with the same core functionality and package.

Q: Are the electrical performance characteristics identical?

A: Yes, except for the second output voltage. Both devices deliver identical quiescent current (40 µA), dropout voltage (0.2V @ 150mA), output current ratings (150mA and 300mA), and protection features. The maximum input voltage (6.5V) and operating temperature range (-40°C to 85°C) are identical.

Q: Can I use the ISL9011AIRJBZ in high-reliability applications?

A: Both devices meet ROHS3 compliance and REACH requirements. The ISL9011AIRJBZ is an active product with ongoing manufacturer support, making it suitable for new designs and long-term production runs. Compliance with specific reliability standards should be confirmed against application requirements.
