ICL7660SCBA Equivalent & Substitute Parts

Part Overview

The ICL7660SCBA 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 ICL7660SCBA is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support long-term product availability for applications currently using this component.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ICL7660SCBA are identified based on strict electrical and mechanical compatibility criteria:

Direct Equivalent (Identical Specifications):

• ICL7660SCBAZ: Identical electrical specifications, same manufacturer (Renesas Electronics Corporation), same package, same output current (45mA), same input voltage range, same switching frequency range, and same operating temperature range. Differs only in packaging format (Tube) and product status (Active vs. Obsolete). RoHS3 compliant.

Similar Substitute (Compatible with Design Considerations):

• TC7660SCOA: Manufactured by Microchip Technology. Maintains identical input voltage range (1.5V to 12V), identical output configuration (Positive or Negative), identical package (8-SOIC), identical operating temperature range (0°C to 70°C), and identical output voltage options (-Vin, 2Vin). Key difference: output current is 20mA versus 45mA on the original part. Switching frequency range extends to 45kHz (versus 35kHz maximum on ICL7660SCBA). RoHS3 compliant.

Parameter Comparison

Engineering Selection Recommendations

ICL7660SCBAZ is the primary recommended substitute for the obsolete ICL7660SCBA. This part maintains complete electrical and mechanical compatibility with identical output current (45mA), input voltage range, output voltage options, switching frequency, and operating temperature specifications. The part is manufactured by the same supplier (Renesas Electronics Corporation) and is currently in active production status with ROHS3 compliance certification. Selection of ICL7660SCBAZ eliminates design modification requirements and ensures direct form-fit-function replacement.

TC7660SCOA is a compatible alternative when supply constraints or design flexibility permit. This Microchip Technology part maintains identical input voltage range, output configuration, package form factor, and operating temperature specifications. The primary design consideration is the reduced output current specification (20mA versus 45mA). TC7660SCOA is suitable for applications where the required load current does not exceed 20mA. This part is also in active production with ROHS3 compliance certification.

Frequently Asked Questions (FAQ)

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

A: Yes. ICL7660SCBAZ is electrically and mechanically identical to ICL7660SCBA. Both parts share the same input voltage range (1.5V to 12V), output current (45mA), output voltage options (-Vin, 2Vin), switching frequency range (10kHz to 35kHz), operating temperature range (0°C to 70°C), and 8-SOIC package. The primary difference is product status (Active versus Obsolete) and RoHS compliance level.

Q: What is the key limitation when using TC7660SCOA as a substitute?

A: TC7660SCOA has a maximum output current rating of 20mA, compared to 45mA for the ICL7660SCBA. Applications requiring output current exceeding 20mA cannot use TC7660SCOA without circuit redesign. All other electrical parameters (input voltage range, output voltage options, operating temperature, and package) remain compatible.

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

A: Yes. ICL7660SCBA, ICL7660SCBAZ, and TC7660SCOA are all supplied in 8-SOIC (0.154", 3.90mm Width) surface mount packages. No PCB layout modifications are required for package compatibility.

Q: What is the difference between ICL7660SCBA and ICL7660SCBAZ packaging?

A: ICL7660SCBA is supplied in standard packaging, while ICL7660SCBAZ is supplied in Tube packaging. Both contain identical die and electrical specifications. Tube packaging is standard for active production parts and does not affect electrical performance or compatibility.

Q: Are substitute parts RoHS compliant?

A: ICL7660SCBA is RoHS non-compliant. Both substitute parts (ICL7660SCBAZ and TC7660SCOA) are ROHS3 compliant, meeting current environmental and regulatory requirements for new designs and procurement.
