Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISL6532ACR is determined by strict alignment of the following critical parameters:

• Package Compatibility: Both main and substitute parts must use the 28-QFN (6x6) surface mount package with exposed pad configuration
• Functional Classification: Both must serve as Memory DDR/DDR2 Regulator PMIC controllers
• Electrical Specifications: Current supply rating of 5.25mA and operating temperature range of 0°C to 70°C must be maintained
• Base Product Number: Both parts share the ISL6532 base product designation, indicating core functional equivalence
• Mounting Technology: Surface mount technology must be consistent across substitution

The ISL6532ACRZ qualifies as a direct substitute based on complete alignment with all specified parameters.

Engineering Selection Recommendations

The ISL6532ACRZ represents a direct functional equivalent to the obsolete ISL6532ACR. Selection between these parts should be based on the following engineering considerations:

Product Status: The ISL6532ACR is classified as obsolete, while the ISL6532ACRZ maintains active product status. For new designs or systems requiring long-term component availability, the ISL6532ACRZ is the appropriate selection.

Compliance and Certifications: The ISL6532ACR carries RoHS non-compliant status. The ISL6532ACRZ compliance status should be verified against specific regulatory requirements for your application region and end-use classification.

Inventory and Supply Chain: The ISL6532ACRZ is currently available with 2092 pieces in stock, compared to 2273 pieces for the obsolete ISL6532ACR. For production continuity, the active substitute part ensures ongoing supply chain access.

Electrical and Mechanical Equivalence: Both parts maintain identical electrical specifications (5.25mA supply current, 0°C to 70°C operating range) and mechanical packaging (28-QFN 6x6 surface mount). Pin-for-pin compatibility is established through shared base product number designation.

Frequently Asked Questions (FAQ)

Q: Can ISL6532ACRZ be used as a direct replacement for ISL6532ACR in existing designs?

A: Yes. The ISL6532ACRZ is pin-for-pin compatible with the ISL6532ACR. Both parts share identical package geometry (28-QFN 6x6), electrical specifications (5.25mA supply current, 0°C to 70°C operating temperature), and functional classification as DDR/DDR2 memory regulators. No circuit modifications are required for substitution.

Q: Why is the ISL6532ACR listed as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production and support for this part number. The ISL6532ACRZ, maintained by Intersil as an active product, provides continued availability for the same functional application.

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

A: The ISL6532ACR is marked as RoHS non-compliant. Compliance status for the ISL6532ACRZ should be confirmed against your specific application requirements and regional regulations before final selection.

Q: What is the significance of the shared ISL6532 base product number?

A: The base product number indicates that both parts are derived from the same core design platform and share functional equivalence. This designation supports the substitution relationship and confirms compatibility for DDR/DDR2 regulator applications.

Q: Is the 28-QFN (6x6) package standard across both parts?

A: Yes. Both the ISL6532ACR and ISL6532ACRZ use the 28-QFN (6x6) surface mount package with exposed pad. This ensures mechanical and thermal compatibility in PCB layouts designed for either part.
