ICL7660ESA-T Equivalent & Substitute Parts

Part Overview

The ICL7660ESA-T is a charge pump switching regulator IC manufactured by Analog Devices Inc./Maxim Integrated, designed for power management applications requiring voltage inversion or division. This component generates positive or negative fixed output voltages (-Vin, nVin, or Vin/2) from a single input supply with 20mA output current capability. The ICL7660ESA-T is classified as obsolete, making identification of active equivalent parts essential for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ICL7660ESA-T is determined by strict equivalence across the following critical parameters:

• Topology: Charge Pump
• Output Configuration: Positive or Negative
• Output Type: Fixed
• Number of Outputs: 1
• Voltage - Input Range: 1.5V to 10V
• Voltage - Output: -Vin, nVin, Vin/2
• Current - Output: 20mA
• Frequency - Switching: 10kHz
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

The identified substitute parts maintain identical electrical specifications and mechanical compatibility. Differences in product status, operating temperature range, and packaging format are noted but do not affect functional interchangeability within the specified parameter constraints.

Engineering Selection Recommendations

The ICL7660ESA-T is obsolete; however, two active equivalent parts are available from the same manufacturer:

ICL7660ESA+T is the primary substitute. It maintains identical electrical and thermal specifications (-40°C ~ 85°C operating range) and is available in Cut Tape and Digi-Reel packaging formats. This part is recommended for designs requiring the full temperature range of the original component.

ICL7660ISA+T is an alternative substitute with a narrower operating temperature range (-20°C ~ 85°C). This part is suitable for applications where the lower temperature limit of -20°C is acceptable. It is supplied in Tape & Reel format.

Both substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, matching the original component's environmental compliance profile.

Frequently Asked Questions (FAQ)

Q: Can ICL7660ESA+T directly replace ICL7660ESA-T? A: Yes. Both parts share identical electrical specifications, output configurations, and 8-SOIC package dimensions. The primary difference is product status (active vs. obsolete) and packaging format availability.

Q: What is the difference between ICL7660ESA+T and ICL7660ISA+T? A: The primary difference is the operating temperature range. ICL7660ESA+T operates from -40°C to 85°C, while ICL7660ISA+T operates from -20°C to 85°C. All other electrical and mechanical parameters are identical. Selection depends on application temperature requirements.

Q: Are the packaging formats interchangeable? A: The 8-SOIC package dimensions are identical across all three parts. However, packaging formats differ: ICL7660ESA-T uses Cut Tape, ICL7660ESA+T offers Cut Tape and Digi-Reel options, and ICL7660ISA+T uses Tape & Reel. Component handling and assembly processes may require format-specific equipment.

Q: Do all three parts meet RoHS compliance? A: Yes. All three parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Which substitute should I select for a new design? A: ICL7660ESA+T is recommended for new designs as it maintains the full operating temperature range of the original component and is actively manufactured. ICL7660ISA+T is suitable if the -20°C to 85°C range meets application requirements.
