ICL7660SIBA Equivalent & Substitute Parts

Part Overview

The ICL7660SIBA is a charge pump switching regulator IC manufactured by Renesas Electronics Corporation, designed for power management applications requiring positive or negative fixed voltage outputs. This device generates either -Vin or 2Vin output from a 1.5V to 12V input supply with 45mA output current capability in an 8-SOIC surface mount package.

The ICL7660SIBA is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ICL7660SIBA is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Topology: Charge Pump
• Output Configuration: Positive or Negative
• Output Type: Fixed
• Number of Outputs: 1
• Voltage - Input Range: 1.5V to 12V
• Voltage - Output: -Vin, 2Vin
• Operating Temperature: -40°C ~ 85°C (TA)
• Package / Case: 8-SOIC (0.154", 3.90mm Width)

Allowable Variation Parameters:

• Current - Output: Substitute must meet or exceed 45mA requirement
• Frequency - Switching: Substitute must operate within compatible range
• Product Status: Active status preferred for ongoing availability
• RoHS Compliance: ROHS3 compliance preferred for regulatory alignment

Substitutes are grouped into two categories: direct equivalents (identical electrical specifications) and similar alternatives (compatible electrical specifications with noted parameter differences).

Engineering Selection Recommendations

ICL7660SIBAZ (Direct Equivalent - Recommended Primary Substitute)

The ICL7660SIBAZ is manufactured by Renesas Electronics Corporation and provides identical electrical specifications to the ICL7660SIBA. This part maintains the same 45mA output current, input voltage range, output voltage configuration, and switching frequency characteristics. The ICL7660SIBAZ holds Active product status, ensuring ongoing availability and supply chain support. The part is ROHS3 compliant, meeting current regulatory requirements. Tube packaging is available. This substitute provides the most direct replacement path with no electrical parameter compromises.

TC7660SEOA (Similar Alternative - Secondary Option)

The TC7660SEOA is manufactured by Microchip Technology and operates as a compatible alternative within the charge pump regulator category. This part maintains identical input voltage range, output voltage configuration, operating temperature range, and package specifications. The TC7660SEOA is ROHS3 compliant and holds Active product status. The output current specification is 20mA, which is lower than the 45mA requirement of the ICL7660SIBA. The switching frequency range extends to 45kHz, compared to the 35kHz maximum of the main part. Selection of the TC7660SEOA is appropriate only when the application load current requirement does not exceed 20mA.

Frequently Asked Questions (FAQ)

Q: Can the ICL7660SIBAZ be used as a direct replacement for the ICL7660SIBA?

A: Yes. The ICL7660SIBAZ is a direct equivalent with identical electrical specifications, including 45mA output current, input voltage range of 1.5V to 12V, and -Vin or 2Vin output configuration. Both parts use the 8-SOIC package. The primary difference is product status: ICL7660SIBAZ is Active, while ICL7660SIBA is Obsolete.

Q: What is the key limitation of the TC7660SEOA as a substitute?

A: The TC7660SEOA has a maximum output current of 20mA, compared to 45mA for the ICL7660SIBA. This part is suitable only for applications where the load current does not exceed 20mA. All other electrical parameters, including input voltage range, output voltage configuration, and operating temperature, are compatible.

Q: Are both substitute parts available in the same package?

A: Yes. Both ICL7660SIBAZ and TC7660SEOA are supplied in 8-SOIC (0.154", 3.90mm Width) surface mount packages, matching the package specification of the ICL7660SIBA.

Q: What is the difference in RoHS compliance between the main part and substitutes?

A: The ICL7660SIBA is RoHS non-compliant. Both substitute parts, ICL7660SIBAZ and TC7660SEOA, are ROHS3 compliant. If regulatory compliance is a design requirement, either substitute part satisfies current RoHS standards.

Q: Can the TC7660SEOA be used in high-current applications?

A: No. The TC7660SEOA is limited to 20mA output current. Applications requiring the full 45mA output capability of the ICL7660SIBA must use the ICL7660SIBAZ.

Q: Are there any differences in switching frequency between the substitutes?

A: The ICL7660SIBA and ICL7660SIBAZ both operate at 10kHz to 35kHz. The TC7660SEOA operates at 10kHz to 45kHz. This difference does not affect compatibility for most applications, as the lower frequency range overlaps completely.
