ICL7660SCPA Equivalent & Substitute Parts
Part Overview
The ICL7660SCPA 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 operates as a ratiometric regulator with a single output capable of delivering 45mA across an input voltage range of 1.5V to 12V, with switching frequency between 10kHz and 35kHz.
The ICL7660SCPA is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure continued availability for maintenance, repair, and new design implementations where this topology is required.

Substitute Part Grouping Explanation
Substitution of the ICL7660SCPA is determined by strict equivalence across the following critical 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 & Mounting: 8-DIP (0.300", 7.62mm) through-hole package
- Manufacturer: Renesas Electronics Corporation
The ICL7660SCPAZ meets all these criteria and is therefore a direct substitute for the obsolete ICL7660SCPA.

Engineering Selection Recommendations
The ICL7660SCPAZ is the direct substitute for the obsolete ICL7660SCPA. Both devices are manufactured by Renesas Electronics Corporation and share identical electrical and mechanical specifications across all critical parameters.
The primary distinction between these parts is product status and compliance certification. The ICL7660SCPA is obsolete and RoHS non-compliant, while the ICL7660SCPAZ is active and ROHS3 compliant. For new designs and ongoing production, the ICL7660SCPAZ is the appropriate selection. Both devices feature MSL 1 (Unlimited) moisture sensitivity rating and are supplied in 8-PDIP packaging suitable for through-hole mounting.
Frequently Asked Questions (FAQ)
Q: Can the ICL7660SCPAZ directly replace the ICL7660SCPA in existing designs?
A: Yes. The ICL7660SCPAZ is electrically and mechanically identical to the ICL7660SCPA. Both devices operate with the same input voltage range (1.5V to 12V), deliver 45mA output current, and are packaged in 8-DIP (0.300", 7.62mm) through-hole format. No circuit modifications are required.
Q: What is the difference between ICL7660SCPA and ICL7660SCPAZ?
A: The primary differences are product status and regulatory compliance. The ICL7660SCPA is obsolete and RoHS non-compliant. The ICL7660SCPAZ is active and ROHS3 compliant. All electrical and mechanical parameters are identical.
Q: Why is the ICL7660SCPA classified as obsolete?
A: The ICL7660SCPA has been discontinued by Renesas Electronics Corporation. The ICL7660SCPAZ serves as the active replacement part with equivalent specifications.
Q: Are there packaging differences between these parts?
A: Both parts use the same 8-DIP (0.300", 7.62mm) package and 8-PDIP supplier device package. The ICL7660SCPAZ is supplied in tube packaging, while the ICL7660SCPA packaging specification was not provided.
Q: What is the moisture sensitivity level for these devices?
A: Both the ICL7660SCPA and ICL7660SCPAZ have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
