Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ISL6271ACR is determined by the following critical parameters:

• Identical manufacturer (Renesas Electronics Corporation)
• Identical base product number (ISL6271)
• Identical package type (20-VFQFN Exposed Pad / 20-QFN 4x4)
• Identical mounting type (Surface Mount)
• Matching electrical specifications: Current supply (380µA), voltage supply range (2.76V ~ 5.5V), and operating temperature range (-25°C ~ 85°C)
• Identical functional configuration (1 buck converter, 2 LDO regulators)

The ISL6271ACRZ meets all substitution criteria as a direct equivalent part from the same manufacturer and product family.

Parameter Comparison

Engineering Selection Recommendations

The ISL6271ACRZ is the direct substitute for the obsolete ISL6271ACR. Both parts share identical electrical specifications, package geometry, and functional configuration, ensuring pin-for-pin and functional compatibility.

Key considerations for selection:

• The ISL6271ACRZ is ROHS3 compliant, meeting current regulatory requirements for new designs and production.
• The ISL6271ACRZ is supplied in Tube packaging, compared to the main part's unspecified packaging.
• The ISL6271ACRZ has an MSL rating of 3 (168 Hours), requiring standard moisture control during storage and handling, compared to the main part's MSL 1 (Unlimited).

Frequently Asked Questions (FAQ)

Q: Can ISL6271ACRZ directly replace ISL6271ACR in existing designs?

A: Yes. Both parts are identical in electrical specifications, pin configuration, package type (20-QFN 4x4), and functional architecture. No design modifications are required.

Q: What is the difference in RoHS compliance between these parts?

A: The ISL6271ACR is RoHS non-compliant, while the ISL6271ACRZ is ROHS3 compliant. For new production or designs subject to RoHS regulations, the ISL6271ACRZ is the appropriate selection.

Q: Are there differences in moisture sensitivity handling?

A: The ISL6271ACR has MSL 1 (Unlimited), requiring no special moisture control. The ISL6271ACRZ has MSL 3 (168 Hours), requiring standard moisture control measures during storage and handling to prevent moisture absorption.

Q: Is the package footprint identical between these parts?

A: Yes. Both parts use the 20-VFQFN Exposed Pad package with 4x4mm dimensions. PCB layouts and assembly processes require no modification.

Q: Why is the main part listed as obsolete?

A: The ISL6271ACR is no longer in active production. The ISL6271ACRZ is the current active equivalent from Renesas Electronics Corporation and is the recommended selection for all new and ongoing applications.
