TC7136CLW Equivalent & Substitute Parts

Part Overview

The TC7136CLW is a 7-segment display driver IC manufactured by Microchip Technology, designed for 4.6-digit display applications in a 44-PLCC surface mount package. This component is classified as obsolete, making equivalent substitutes necessary for new designs and production continuity. The part operates at 9V supply voltage with an operating temperature range of 0°C to 70°C. Due to its obsolete status, active equivalent parts from Analog Devices Inc./Maxim Integrated provide direct functional replacement options while maintaining compatibility with existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the TC7136CLW is based on the following critical parameters:

Primary Substitutes (Direct Equivalents):

• ICL7136CQH+, ICL7136CQH+D, and ICL7136CQH+TD are functionally equivalent display drivers from Analog Devices Inc./Maxim Integrated
• All three variants maintain identical electrical specifications: 4.6-digit display resolution, 44-PLCC package, 9V supply voltage, and 0°C to 70°C operating temperature range
• These parts differ only in packaging format (bulk, tube, or tape & reel) and are all in active production status
• All direct equivalents are ROHS3 compliant, addressing the RoHS non-compliance limitation of the original part

Secondary Substitute (Package/Mounting Variant):

• ICM7224IPL+ is a 7-segment LCD driver with 4.5-digit resolution in a 40-DIP through-hole package
• This part operates at 3V to 6V supply voltage and -20°C to 85°C temperature range
• The different package type (40-DIP vs. 44-PLCC) and mounting method (through-hole vs. surface mount) require circuit board redesign
• This substitute is suitable only when board layout modifications are acceptable

Engineering Selection Recommendations

For Direct Pin-Compatible Replacement: Select ICL7136CQH+, ICL7136CQH+D, or ICL7136CQH+TD based on packaging requirements. All three maintain identical electrical and mechanical compatibility with the TC7136CLW footprint. Choose the packaging variant that matches your procurement and assembly process:

• ICL7136CQH+: Bulk packaging for standard component handling
• ICL7136CQH+D: Tube packaging for moderate volume applications
• ICL7136CQH+TD: Tape & Reel packaging for automated assembly lines

All direct equivalents are ROHS3 compliant and in active production, eliminating obsolescence risk.

For Applications Requiring Extended Temperature Range: The ICM7224IPL+ provides a wider operating temperature range (-20°C to 85°C) and lower supply voltage range (3V to 6V). This substitute requires circuit board redesign due to different package type (40-DIP through-hole vs. 44-PLCC surface mount) and is suitable only when thermal performance improvements justify layout modifications.

Compliance Considerations: The TC7136CLW is RoHS non-compliant. All recommended substitutes are ROHS3 compliant, meeting current environmental and regulatory requirements for new designs and production.

Frequently Asked Questions (FAQ)

Q: Can ICL7136CQH+ be used as a direct replacement for TC7136CLW without circuit modifications? A: Yes. The ICL7136CQH+ series (including +D and +TD variants) maintains identical pin configuration, package footprint (44-PLCC), supply voltage (9V), operating temperature range (0°C to 70°C), and functional specifications. No circuit redesign is required.

Q: What is the difference between ICL7136CQH+, ICL7136CQH+D, and ICL7136CQH+TD? A: These three parts are electrically identical. The suffix indicates packaging format only: no suffix for bulk, +D for tube packaging, and +TD for tape & reel. Select based on your assembly process and procurement volume requirements.

Q: Why is ICM7224IPL+ listed as a substitute if it requires board redesign? A: ICM7224IPL+ is a functional alternative for applications where extended temperature range (-20°C to 85°C) and lower supply voltage (3V to 6V) provide design advantages. The 40-DIP through-hole package and 4.5-digit resolution represent different specifications that may suit alternative applications, but it is not a drop-in replacement.

Q: Are all substitute parts RoHS compliant? A: Yes. All recommended substitutes (ICL7136CQH+, ICL7136CQH+D, ICL7136CQH+TD, and ICM7224IPL+) are ROHS3 compliant. The original TC7136CLW is RoHS non-compliant.

Q: What is the Moisture Sensitivity Level (MSL) for the substitute parts? A: ICL7136CQH+, ICL7136CQH+D, and ICL7136CQH+TD all have MSL 3 (168 Hours), matching the original part. ICM7224IPL+ has MSL 1 (Unlimited), providing superior moisture resistance.

Q: Can I mix packaging variants (bulk, tube, tape & reel) in the same production run? A: Yes. All three ICL7136CQH+ variants are electrically and mechanically identical. Mixing packaging formats is acceptable from a technical standpoint, though procurement and inventory management practices may vary by organization.
