ISL6333IRZ Equivalent & Substitute Parts

Part Overview

The ISL6333IRZ is a Power Management IC (PMIC) controller designed for Intel VR11 voltage regulation applications. This device functions as a single-output voltage regulator controller in a 48-QFN (7x7) surface mount package. The ISL6333IRZ is currently in Last Time Buy status, indicating end-of-life production. Identifying equivalent and substitute parts is necessary to ensure continued availability and support for new production runs and system redesigns.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISL6333IRZ are determined by strict equivalence across the following critical parameters:

• Identical base product number (ISL6333)
• Matching input voltage range (5V ~ 12V)
• Matching output voltage range (0.5V ~ 1.6V)
• Single output configuration
• Identical package type (48-VFQFN Exposed Pad)
• Identical operating temperature range (-40°C ~ 85°C)
• Identical functional application (Intel VR11 voltage regulator controller)
• Equivalent compliance certifications (ROHS3, REACH Unaffected)

The primary distinction between the main part and its substitute is the packaging format: the ISL6333IRZ is supplied in Tube packaging, while the ISL6333IRZ-T is supplied in Tape & Reel (TR) format. Both variants share identical electrical specifications and mechanical dimensions.

Parameter Comparison

Engineering Selection Recommendations

The ISL6333IRZ-T is the direct functional equivalent of the ISL6333IRZ. Both parts are manufactured by Renesas Electronics Corporation and share identical electrical specifications, thermal characteristics, and compliance certifications. The ISL6333IRZ-T maintains Active product status, ensuring continued availability and manufacturing support.

Selection between these parts is determined by supply chain and assembly requirements. The ISL6333IRZ-T in Tape & Reel format is suitable for automated pick-and-place assembly processes and high-volume production environments. The ISL6333IRZ in Tube format is appropriate for lower-volume applications or manual assembly workflows.

Both parts meet ROHS3 compliance and REACH requirements, with identical moisture sensitivity ratings. No electrical or thermal derating is required when substituting between these variants.

Frequently Asked Questions (FAQ)

Q: Can ISL6333IRZ-T replace ISL6333IRZ in existing designs?

A: Yes. The ISL6333IRZ-T is electrically and mechanically equivalent to the ISL6333IRZ. Both parts feature identical input/output voltage specifications, operating temperature range, and package dimensions. The only difference is the packaging format (Tape & Reel versus Tube).

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging is used for manual handling and lower-volume applications. Tape & Reel (TR) packaging is designed for automated assembly equipment and high-volume production. The components themselves are identical; only the delivery format differs.

Q: Are there any compliance or certification differences between these parts?

A: No. Both ISL6333IRZ and ISL6333IRZ-T carry identical ROHS3 compliance, REACH Unaffected status, and Moisture Sensitivity Level 3 ratings. No additional qualification is required when switching between variants.

Q: Why is ISL6333IRZ marked as Last Time Buy?

A: Last Time Buy status indicates that Renesas Electronics Corporation has discontinued production of the ISL6333IRZ in Tube format. The ISL6333IRZ-T in Tape & Reel format remains in Active production status and is the recommended part for new designs and ongoing production.

Q: Can these parts be used interchangeably on the same PCB assembly line?

A: Yes, provided your assembly equipment supports both packaging formats. Tube-packaged parts require manual placement or compatible feeder systems, while Tape & Reel parts integrate directly with standard pick-and-place machinery. Electrical performance is identical regardless of packaging format.
