ICL7116C/D Equivalent & Substitute Parts

Part Overview

The ICL7116C/D is a Display Driver for 4.6 Digit applications, manufactured by Analog Devices Inc./Maxim Integrated. This component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing design requirements and production continuity. The die package format and single supply voltage specification (9V) define the core functional parameters for substitution evaluation.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ICL7116C/D is based on the following critical parameters that must remain consistent:

• Base Product Number: ICL7116 (same functional core)
• Resolution: 4.6 Digit display driver capability
• Voltage Supply: Single supply at 9V
• Operating Temperature Range: 0°C ~ 70°C
• Manufacturer: Analog Devices Inc./Maxim Integrated (same source)
• Product Category: Data Acquisition / Display Driver

The identified substitute part, ICL7116CQH+D, maintains all functional electrical parameters while transitioning from die package to a 44-PLCC surface mount package. This substitution is valid because the core display driver functionality, voltage specifications, temperature range, and resolution remain unchanged. The package change from die to 44-PLCC represents a standard form factor upgrade that enables direct integration into standard PCB assembly processes.

Parameter Comparison

Engineering Selection Recommendations

The ICL7116CQH+D is the active equivalent for the obsolete ICL7116C/D. Selection of this substitute is supported by the following factors:

• Product Status: The substitute part is active and available, whereas the main part is obsolete. This ensures long-term supply continuity and manufacturing support.
• Compliance Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory consistency.
• Functional Equivalence: Identical resolution (4.6 Digit), voltage supply (9V), and operating temperature range (0°C ~ 70°C) guarantee functional compatibility.
• Manufacturer Continuity: Both parts originate from Analog Devices Inc./Maxim Integrated, ensuring consistent design specifications and technical support.
• Package Transition: The shift from die to 44-PLCC package represents a standard industry upgrade that improves manufacturability and integration into standard PCB assembly workflows.

Frequently Asked Questions (FAQ)

Q: Why is the ICL7116C/D obsolete? A: The ICL7116C/D is classified as obsolete by the manufacturer. The active equivalent, ICL7116CQH+D, provides the same functional display driver capability in a standard 44-PLCC package format.

Q: Are the electrical specifications identical between the main part and substitute? A: Yes. Both parts operate at 9V single supply, support 4.6 Digit resolution, and function across the 0°C ~ 70°C temperature range. The functional electrical parameters are equivalent.

Q: What is the primary difference between ICL7116C/D and ICL7116CQH+D? A: The main difference is the package format. The ICL7116C/D is supplied as a die, while the ICL7116CQH+D is packaged in a 44-PLCC (16.59x16.59) surface mount configuration. This enables standard PCB assembly integration.

Q: Does the package change affect circuit design? A: The package change from die to 44-PLCC does not alter the core electrical functionality. However, PCB layout, pin routing, and assembly processes will differ. Refer to the respective datasheets for pinout and application circuit details.

Q: Are both parts RoHS compliant? A: Yes. Both the ICL7116C/D and ICL7116CQH+D are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the Moisture Sensitivity Level (MSL) difference? A: The ICL7116C/D has MSL 1 (Unlimited), while the ICL7116CQH+D has MSL 3 (168 Hours). This affects storage and handling procedures. The 44-PLCC package requires standard moisture control during storage and assembly.

Q: Can I use ICL7116CQH+D as a direct replacement in existing designs? A: The ICL7116CQH+D is functionally equivalent but requires PCB redesign due to the package format change from die to 44-PLCC. Pinout verification and layout modifications are necessary.
