Key Parameters

Substitute Part Grouping Explanation

Substitution of the ZM33064CL is determined by the following critical parameters:

• Functional Type: Simple reset/power-on reset supervisor with single-channel voltage monitoring
• Voltage Threshold: 4.6V monitoring threshold
• Output Configuration: Open drain or open collector output
• Reset Logic: Active low reset signal
• Package Compatibility: TO-92-3 / TO-226-3 through-hole package
• Operating Temperature: -40°C to 85°C range
• Regulatory Compliance: ROHS3 compliant, REACH unaffected

The MC33064P-5RAG manufactured by onsemi meets all these criteria and is classified as an active product, making it a direct functional equivalent for the obsolete ZM33064CL.

Parameter Comparison

Engineering Selection Recommendations

The MC33064P-5RAG is the recommended substitute for the obsolete ZM33064CL based on the following factors:

• Functional Equivalence: Both devices share identical voltage threshold (4.6V), output configuration (open drain/open collector), reset logic (active low), and single-channel monitoring capability.
• Package Compatibility: Both utilize TO-92-3 / TO-226-3 through-hole packages, enabling direct board-level replacement without PCB redesign.
• Temperature Range: Identical operating temperature specification (-40°C to 85°C) ensures equivalent thermal performance in target applications.
• Regulatory Compliance: Both devices maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements.
• Product Status: The MC33064P-5RAG is an active product with confirmed inventory availability, ensuring long-term supply chain viability compared to the obsolete ZM33064CL.

Frequently Asked Questions (FAQ)

Q: Can the MC33064P-5RAG directly replace the ZM33064CL without circuit modifications?

A: Yes. Both devices are functionally equivalent across all critical parameters: 4.6V threshold, active-low reset, open drain/open collector output, and identical operating temperature range. The TO-92-3 package pinout is compatible, allowing direct substitution.

Q: What is the difference between the TO-92-3 and TO-226-3 package designations?

A: TO-92-3 and TO-226-3 refer to the same three-lead through-hole package. TO-226 is the formal JEDEC designation, while TO-92 is the common industry reference. Both terms describe the identical physical package used by both the ZM33064CL and MC33064P-5RAG.

Q: Does the MC33064P-5RAG meet the same compliance standards as the ZM33064CL?

A: Yes. Both devices are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component procurement.

Q: Why is the ZM33064CL listed as obsolete?

A: Obsolescence typically results from manufacturer discontinuation decisions. The MC33064P-5RAG, as an active product from onsemi, provides continued availability for applications requiring this supervisor functionality.

Q: Are there any differences in propagation delay between these devices?

A: The ZM33064CL specifies 1.5µs typical propagation delay. The MC33064P-5RAG does not provide this specification in the available data. For applications with strict timing requirements, detailed datasheet comparison is necessary.

Q: What is the inventory status for these parts?

A: The ZM33064CL has 1080 pieces in stock as new original inventory. The MC33064P-5RAG has 1059 pieces in stock as new original inventory in cut tape packaging.
