Substitute Part Grouping Explanation

Substitution of the ICL7660SIBAT is determined by strict equivalence across the following critical parameters:

• Topology: Charge Pump architecture
• Output Configuration: Positive or Negative capability
• Output Type: Fixed voltage output
• Number of Outputs: Single output
• Voltage Range: Input 1.5V to 12V; Output -Vin, 2Vin
• Current Rating: 45mA output current
• Switching Frequency: 10kHz to 35kHz
• Package: 8-SOIC (0.154", 3.90mm Width)
• Operating Temperature: -40°C to 85°C
• Mounting Type: Surface Mount

The ICL7660SIBAZT meets all these criteria and qualifies as a direct substitute. Both parts share identical electrical specifications, functional characteristics, and physical packaging requirements.

Parameter Comparison

Engineering Selection Recommendations

The ICL7660SIBAZT is the direct substitute for the obsolete ICL7660SIBAT. Both parts are manufactured by Renesas Electronics Corporation and maintain identical electrical and mechanical specifications across all critical parameters.

The primary distinction between these parts is product status and regulatory compliance. The ICL7660SIBAT is obsolete, while the ICL7660SIBAZT maintains active product status. Additionally, the ICL7660SIBAZT is ROHS3 compliant, whereas the ICL7660SIBAT is RoHS non-compliant. For new designs or applications requiring regulatory compliance, the ICL7660SIBAZT is the appropriate selection.

Both parts are supplied in 8-SOIC packaging with identical pinout and footprint compatibility, enabling direct board-level substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can the ICL7660SIBAZT replace the ICL7660SIBAT in existing designs?

A: Yes. The ICL7660SIBAZT is electrically and mechanically equivalent to the ICL7660SIBAT. Both parts share identical input voltage range (1.5V to 12V), output current (45mA), switching frequency (10kHz to 35kHz), operating temperature range (-40°C to 85°C), and 8-SOIC package footprint. Direct substitution is possible without circuit modification.

Q: What is the primary reason to transition from ICL7660SIBAT to ICL7660SIBAZT?

A: The ICL7660SIBAT is classified as obsolete, creating supply chain risk. The ICL7660SIBAZT maintains active product status with higher inventory availability. Additionally, the ICL7660SIBAZT is ROHS3 compliant, supporting regulatory requirements for new applications.

Q: Are the packaging and pinout identical between these parts?

A: Yes. Both the ICL7660SIBAT and ICL7660SIBAZT are supplied in 8-SOIC (0.154", 3.90mm Width) packaging with identical pinout configuration. PCB footprints are directly compatible.

Q: What are the key electrical parameters that define substitution for this charge pump regulator?

A: Substitution is determined by matching topology (charge pump), output configuration (positive or negative), output type (fixed), number of outputs (1), input voltage range (1.5V to 12V), output voltage levels (-Vin, 2Vin), output current (45mA), switching frequency (10kHz to 35kHz), and operating temperature range (-40°C to 85°C).

Q: Is the ICL7660SIBAZT suitable for applications requiring RoHS compliance?

A: Yes. The ICL7660SIBAZT is ROHS3 compliant. The original ICL7660SIBAT is RoHS non-compliant. For applications with regulatory compliance requirements, the ICL7660SIBAZT is the appropriate selection.
