ICL7109CPL Equivalent & Substitute Parts

Part Overview

The ICL7109CPL is a 12-bit analog-to-digital converter utilizing dual-slope architecture, manufactured by Analog Devices Inc./Maxim Integrated. This component features differential input configuration with parallel data interface and operates on ±5V supply voltages. The ICL7109CPL is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations. Substitute parts maintain identical electrical and mechanical specifications while offering improved product status and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICL7109CPL is determined by strict equivalence across the following critical parameters: 12-bit resolution, 30 samples-per-second sampling rate, single differential input, parallel data interface, dual-slope architecture, external reference type, ±5V analog and digital supply voltages, 0°C to 70°C operating temperature range, 40-DIP package configuration, through-hole mounting, and MSL Level 1 rating.

Substitute parts are categorized as follows:

Direct Manufacturer Equivalents (Analog Devices Inc./Maxim Integrated): ICL7109CPL+, ICL7109CPL+2, and ICL7109EPL+ maintain identical parametric specifications and are manufactured by the original supplier. These parts differ from the main part only in product status (Active vs. Obsolete) and RoHS compliance certification.

Manufacturer-Recommended Cross-Reference (Microchip Technology): TC7109ACPL and TC7109CPL are functionally equivalent alternatives from Microchip Technology. These parts maintain all critical electrical and mechanical parameters with the exception of supply voltage specification, which is listed as 5V (single polarity) rather than ±5V. This difference reflects datasheet documentation conventions and does not indicate functional incompatibility in applications requiring ±5V dual-supply operation.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the obsolete ICL7109CPL, direct substitution with ICL7109CPL+, ICL7109CPL+2, or ICL7109EPL+ is supported. These parts are manufactured by Analog Devices Inc./Maxim Integrated and maintain full parametric equivalence while offering Active product status and ROHS3 compliance certification.

For new designs or applications where supply chain continuity is a priority, TC7109CPL or TC7109ACPL from Microchip Technology provide functionally equivalent alternatives. Both Microchip parts are in Active status with ROHS3 compliance and maintain all critical electrical and mechanical specifications.

Selection between Analog Devices and Microchip alternatives should be based on supply availability, lead time requirements, and existing design documentation. All listed substitute parts are electrically and mechanically interchangeable within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can ICL7109CPL be directly replaced with TC7109CPL?

A: Yes. Both parts share identical 12-bit resolution, 30 samples-per-second sampling rate, single differential input, parallel data interface, dual-slope architecture, external reference type, 0°C to 70°C operating temperature range, 40-DIP package, and through-hole mounting. The supply voltage specification difference (±5V vs. 5V notation) reflects manufacturer datasheet conventions and does not affect functional compatibility in dual-supply applications.

Q: What is the difference between ICL7109CPL+ and ICL7109CPL+2?

A: Both parts are manufactured by Analog Devices Inc./Maxim Integrated and maintain identical electrical and mechanical specifications. The primary differences are packaging designation (Tube) and inventory availability. Selection between these parts should be based on supply availability and procurement requirements.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed (ICL7109CPL+, ICL7109CPL+2, ICL7109EPL+, TC7109ACPL, TC7109CPL) are ROHS3 compliant. The original ICL7109CPL is RoHS non-compliant. This compliance improvement is a key advantage of substitution for applications subject to RoHS requirements.

Q: Can substitute parts be used in existing PCB designs without modification?

A: Yes. All substitute parts utilize the 40-DIP package with identical pin configuration and through-hole mounting. Direct PCB substitution is supported without design modification.

Q: What is the inventory status of substitute parts?

A: ICL7109CPL+ (2100 pcs), ICL7109CPL+2 (937 pcs), ICL7109EPL+ (1174 pcs), TC7109ACPL (1160 pcs), and TC7109CPL (4206 pcs) are all listed as New Original In Stock. Availability should be confirmed with the component supplier for current procurement.
