Key Parameters

Substitute Part Grouping Explanation

Substitution of the ICL7660SCBA-T is determined by strict equivalence across the following electrical and mechanical parameters:

• Topology & Function: Charge pump switching regulator with ratiometric function
• Output Configuration: Positive or negative fixed voltage capability
• Electrical Specifications: Input voltage range 1.5V to 12V, output current 45mA, switching frequency 10kHz to 35kHz
• Package Compatibility: 8-SOIC surface mount package with identical physical dimensions (0.154", 3.90mm width)
• Operating Temperature Range: 0°C to 70°C
• Moisture Sensitivity: MSL 1 (Unlimited)

The ICL7660SCBAZ-T meets all these criteria as a direct functional equivalent manufactured by the same supplier using the same base product number (ICL7660).

Parameter Comparison

Engineering Selection Recommendations

The ICL7660SCBAZ-T is the direct substitute for the obsolete ICL7660SCBA-T. Both parts share identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility. The primary distinction is product lifecycle status: the ICL7660SCBAZ-T is active and available in production quantities, while the ICL7660SCBA-T is obsolete.

The ICL7660SCBAZ-T additionally provides ROHS3 compliance, meeting current environmental and regulatory requirements for new designs and manufacturing. The part is available in Cut Tape (CT) and Digi-Reel packaging formats, supporting both prototype and high-volume production workflows.

Frequently Asked Questions (FAQ)

Q: Can the ICL7660SCBAZ-T be used as a direct replacement for the ICL7660SCBA-T?

A: Yes. Both parts are manufactured by Renesas Electronics Corporation and share identical electrical specifications, output configurations, switching topology, and 8-SOIC package dimensions. No circuit modifications are required.

Q: What is the difference between the ICL7660SCBA-T and ICL7660SCBAZ-T?

A: The primary differences are product status and regulatory compliance. The ICL7660SCBA-T is obsolete and RoHS non-compliant. The ICL7660SCBAZ-T is active, ROHS3 compliant, and available in standard production packaging.

Q: Are there any package or pinout differences?

A: No. Both parts use the 8-SOIC (0.154", 3.90mm width) surface mount package with identical pinout and physical dimensions.

Q: What output voltages does this charge pump regulator support?

A: The ICL7660SCBAZ-T generates either negative voltage (-Vin) or doubled positive voltage (2Vin) depending on circuit configuration, with input voltage range from 1.5V to 12V and maximum output current of 45mA.

Q: Is the ICL7660SCBAZ-T suitable for new designs?

A: Yes. The active product status and ROHS3 compliance make it appropriate for new designs and production applications requiring charge pump voltage conversion with the specified electrical and thermal characteristics.
