ISL69144IRAZ Equivalent & Substitute Parts

Part Overview

The ISL69144IRAZ is a Power Management Integrated Circuit (PMIC) functioning as a controller for AMD SVI2 voltage regulators with dual output capability. This device operates across an input voltage range of 4.5V to 25V and delivers output voltages from 0V to 3.05V, making it suitable for AMD processor power delivery applications. The ISL69144IRAZ is classified as obsolete, which necessitates identification of equivalent substitute components for new designs and ongoing production requirements. The primary substitute maintains identical electrical and mechanical specifications while offering improved product availability through active manufacturing status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISL69144IRAZ is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Electrical Specifications:

• Input voltage range: 4.5V ~ 25V
• Output voltage range: 0V ~ 3.05V
• Dual output configuration (2 outputs)
• Operating temperature range: -40°C ~ 85°C

Mechanical Specifications:

• Package type: 40-WFQFN Exposed Pad
• Mounting method: Surface Mount
• Supplier device package: 40-TQFN (5x5)

Compliance & Regulatory:

• RoHS3 Compliance
• REACH Unaffected status
• Moisture Sensitivity Level 3 (168 Hours)

The ISL69144IRAZ-T qualifies as a direct substitute based on complete parameter alignment. The distinction between these parts is limited to packaging format: the original part is supplied in Tray packaging, while the substitute is supplied in Tape & Reel (TR) format. Both parts share identical electrical performance, thermal characteristics, and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The ISL69144IRAZ-T is the direct functional equivalent of the ISL69144IRAZ. Selection between these parts should be based on the following factors:

For New Designs and Production: The ISL69144IRAZ-T is the appropriate selection due to its Active product status. This ensures ongoing manufacturer support, continued availability, and compliance with current supply chain requirements. The part maintains full electrical and thermal equivalence with the obsolete ISL69144IRAZ.

Packaging Considerations: The ISL69144IRAZ-T is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. If Tray packaging is specifically required for manual assembly or other handling procedures, this distinction must be addressed through packaging conversion or alternative sourcing arrangements.

Compliance & Regulatory: Both parts maintain identical RoHS3 compliance and REACH Unaffected status, ensuring regulatory equivalence for applications subject to environmental and hazardous substance restrictions.

Moisture Sensitivity: Both parts carry MSL 3 (168 Hours) classification, requiring identical handling and storage protocols during manufacturing and assembly operations.

Frequently Asked Questions (FAQ)

Q: Can the ISL69144IRAZ-T be used as a direct replacement for the ISL69144IRAZ in existing designs?

A: Yes. The ISL69144IRAZ-T is electrically and mechanically equivalent to the ISL69144IRAZ. All electrical specifications, thermal characteristics, package dimensions, and regulatory compliance are identical. The only difference is the packaging format (Tape & Reel versus Tray).

Q: What is the primary reason for substituting the ISL69144IRAZ?

A: The ISL69144IRAZ is classified as obsolete. The ISL69144IRAZ-T is the active equivalent part, ensuring continued availability and manufacturer support for new production and design implementations.

Q: Are there any differences in electrical performance between these parts?

A: No. Both parts operate across identical input voltage ranges (4.5V ~ 25V), deliver the same output voltage range (0V ~ 3.05V), support dual output configuration, and maintain the same operating temperature range (-40°C ~ 85°C).

Q: Does the packaging format difference affect circuit board design?

A: No. Both parts use the same 40-WFQFN Exposed Pad package with 40-TQFN (5x5) footprint. The packaging format difference (Tray versus Tape & Reel) affects only the supply and handling method, not the physical component or PCB layout.

Q: Are moisture sensitivity requirements the same for both parts?

A: Yes. Both parts carry MSL 3 (168 Hours) classification, requiring identical storage conditions, handling procedures, and reflow processing protocols.

Q: Can the ISL69144IRAZ-T be used in applications requiring AMD SVI2 voltage regulation?

A: Yes. The ISL69144IRAZ-T is specified as a controller for AMD SVI2 voltage regulator applications, identical to the original ISL69144IRAZ.

Q: What is the inventory status of the substitute part?

A: The ISL69144IRAZ-T is actively manufactured and maintained in production inventory, providing reliable long-term availability compared to the obsolete ISL69144IRAZ.
