Substitute Part Grouping Explanation

Substitution eligibility for the ISL9000IRMMZ is determined by the following critical parameters:

Package Compatibility: Identical 10-DFN (3x3) Surface Mount package with exposed pad
Output Configuration: Dual positive fixed-output topology
Electrical Performance: Maximum input voltage 6.5V, output current capability 300mA per channel, voltage dropout specification 0.325V @ 300mA
Protection Architecture: Over-current, over-temperature, and under-voltage lockout protection
Operating Temperature Range: -40°C to 85°C
Control Interface: Enable and Power On Reset functionality
Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The ISL9000AIRMNZ meets all substitution criteria. Both devices share identical electrical specifications, package geometry, and protection feature sets. The primary distinction is product status and output voltage configuration on the second channel.

Engineering Selection Recommendations

The ISL9000AIRMNZ is an active production substitute for the obsolete ISL9000IRMMZ. Both devices maintain identical electrical specifications, package geometry, and protection feature architecture. Selection between these parts depends on application-specific requirements:

ISL9000AIRMNZ Selection Criteria: Choose this active production part for new designs or ongoing production requiring dual-output regulation. The device is currently manufactured and stocked. The second output channel provides 3.3V instead of 3V; circuit design must accommodate this voltage difference or employ external voltage adjustment if 3V output is required on both channels.

Moisture Sensitivity Consideration: The ISL9000AIRMNZ carries MSL 3 (168 hours) compared to the ISL9000IRMMZ MSL 1 (unlimited). This affects storage and handling protocols but does not impact electrical performance or functional compatibility.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component substitution.

Frequently Asked Questions (FAQ)

Q: Can the ISL9000AIRMNZ directly replace the ISL9000IRMMZ in existing designs?

A: Electrical and mechanical compatibility is confirmed. The ISL9000AIRMNZ provides identical input voltage range, output current capability, dropout voltage, protection features, and package footprint. Circuit design must account for the second output voltage difference: 3.3V on ISL9000AIRMNZ versus 3V on ISL9000IRMMZ. If both outputs require 3V, external voltage adjustment or alternative part selection may be necessary.

Q: What is the significance of the different Moisture Sensitivity Levels?

A: MSL 1 (unlimited) on the ISL9000IRMMZ permits indefinite storage without moisture absorption concerns. MSL 3 (168 hours) on the ISL9000AIRMNZ requires component use within 168 hours of package opening under specified humidity conditions. This affects warehouse handling and production scheduling but does not alter electrical performance or functional operation.

Q: Are both parts suitable for the same PCB assembly process?

A: Yes. Both devices use identical 10-DFN (3x3) Surface Mount packages with exposed pads. PCB footprints, reflow profiles, and assembly procedures are interchangeable.

Q: Why is the ISL9000IRMMZ classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The ISL9000AIRMNZ represents the active production equivalent, ensuring continued supply chain availability and manufacturing support.

Q: What protection features are included in both devices?

A: Both the ISL9000IRMMZ and ISL9000AIRMNZ incorporate over-current protection, over-temperature protection, and under-voltage lockout (UVLO) functionality. These features operate identically across both part numbers.

Q: Are there any compliance differences between the two parts?

A: No. Both devices maintain ROHS3 compliance and REACH unaffected status. Regulatory and environmental compliance requirements are equivalent.
