TC7136CLW713 Equivalent & Substitute Parts

Part Overview

The TC7136CLW713 is a 7-segment display driver IC designed for 4.6-digit display applications in data acquisition systems. Manufactured by Microchip Technology, this component operates at 9V supply voltage with a 44-PLCC surface mount package. The part is currently obsolete, making equivalent substitutes necessary for new designs and ongoing production support. Substitute parts must maintain functional compatibility with 4.6-digit display driving capability while meeting the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TC7136CLW713 are grouped based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Display driver functionality for 4.6-digit display applications
• 44-PLCC (16.59x16.59) package configuration
• Surface mount mounting type
• Operating temperature range: 0°C ~ 70°C
• Voltage supply: 9V
• Moisture Sensitivity Level: 3 (168 Hours)

Substitute Categories:

Group 1: Direct Pin-Compatible Substitutes (44-PLCC Package)

• ICL7136CQH+ (standard packaging)
• ICL7136CQH+D (tube packaging)
• ICL7136CQH+TD (tape & reel packaging)

These parts maintain identical package geometry, pin configuration, and electrical specifications. All are manufactured by Analog Devices Inc./Maxim Integrated and are active products with RoHS3 compliance.

Group 2: Functional Alternative (Different Package)

• ICM7224IPL+

This part provides 7-segment display driver functionality but uses a 40-DIP through-hole package instead of surface mount. It operates at 3V ~ 6V supply voltage and supports 4.5-digit displays. This substitute requires circuit board redesign and is suitable only when package conversion is feasible.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Recommended):

The ICL7136CQH+ series (ICL7136CQH+, ICL7136CQH+D, ICL7136CQH+TD) provides the most suitable substitution for TC7136CLW713. These parts maintain identical package geometry, pin configuration, and electrical operating parameters. All three variants are active products with RoHS3 compliance, addressing the obsolescence of the original Microchip part. Selection among the three variants depends on procurement and assembly requirements:

• ICL7136CQH+: Standard packaging for general procurement
• ICL7136CQH+D: Tube packaging for manual assembly operations
• ICL7136CQH+TD: Tape & reel packaging for automated assembly lines

For Functional Alternative (Circuit Redesign Required):

The ICM7224IPL+ offers 7-segment display driver functionality but requires circuit board redesign due to package conversion from 44-PLCC surface mount to 40-DIP through-hole. This substitute operates at 3V ~ 6V supply voltage, which differs from the 9V requirement of the original part. The ICM7224IPL+ supports 4.5-digit displays compared to the 4.6-digit specification of TC7136CLW713. This option is suitable only when board layout modifications and power supply adjustments are feasible.

Frequently Asked Questions (FAQ)

Q: Can ICL7136CQH+ be used as a direct replacement for TC7136CLW713?

A: Yes. The ICL7136CQH+ maintains identical 44-PLCC package geometry, pin configuration, and electrical specifications including 9V supply voltage and 0°C ~ 70°C operating temperature range. No circuit modifications are required for direct substitution.

Q: What is the difference between ICL7136CQH+, ICL7136CQH+D, and ICL7136CQH+TD?

A: These three parts are electrically identical. The differences are in packaging format: ICL7136CQH+ is standard packaging, ICL7136CQH+D is supplied in tubes for manual assembly, and ICL7136CQH+TD is supplied in tape & reel format for automated pick-and-place assembly. Select based on your assembly process requirements.

Q: Why is ICM7224IPL+ listed as a substitute if it requires redesign?

A: ICM7224IPL+ is included as a functional alternative for applications where circuit board redesign is acceptable. It provides 7-segment display driver capability but uses a different package type (40-DIP through-hole) and operates at 3V ~ 6V supply voltage. This substitute is not recommended for direct replacement without engineering review.

Q: Are the substitute parts RoHS compliant?

A: Yes. All ICL7136CQH+ variants are RoHS3 compliant, addressing the RoHS non-compliance status of the obsolete TC7136CLW713. The ICM7224IPL+ is also RoHS3 compliant.

Q: What is the moisture sensitivity level of the substitute parts?

A: The ICL7136CQH+ series maintains MSL 3 (168 Hours), identical to the original part. The ICM7224IPL+ has MSL 1 (Unlimited), indicating superior moisture resistance for storage and handling.

Q: Can I use ICM7224IPL+ without modifying my circuit board?

A: No. The ICM7224IPL+ uses a 40-DIP through-hole package, while the original TC7136CLW713 uses a 44-PLCC surface mount package. Circuit board redesign is required. Additionally, the supply voltage range differs (3V ~ 6V versus 9V), requiring power supply modifications.
