TC7107AIPL Equivalent & Substitute Parts

Part Overview

The TC7107AIPL is a 40-pin DIP integrated circuit manufactured by Microchip Technology, designed as a driver for 7-segment displays with 4.6-digit capability. This component is classified under Data Acquisition and is currently in active product status with 653 units available in stock. The TC7107AIPL operates at 5V supply voltage and supports through-hole mounting, making it suitable for legacy and industrial display applications. Substitute parts may be required due to component obsolescence, supply chain constraints, or design requirements for alternative digit configurations and operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC7107AIPL with ICM7228AIPIZ or ICM7228CIPIZ is based on the following allowed parameters:

• Both substitute parts are 7-segment LED drivers with through-hole mounting capability
• All parts maintain ROHS3 compliance and REACH unaffected status
• All parts feature MSL rating of 1 (Unlimited)
• Supply voltage compatibility exists within the operating ranges: TC7107AIPL operates at 5V, while ICM7228 variants operate at 4V ~ 6V, encompassing the 5V requirement
• Operating temperature ranges overlap: TC7107AIPL (-25°C ~ 85°C) and ICM7228 variants (-40°C ~ 85°C)
• All parts use 28-DIP or 40-DIP through-hole packages with 0.600" (15.24mm) pitch

The primary distinction is digit configuration: TC7107AIPL supports 4.6 digits, while ICM7228AIPIZ and ICM7228CIPIZ support 8 digits. This substitution is valid when the application can accommodate the increased digit capability or when only a subset of available digits is utilized.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and full compliance with ROHS3 and REACH requirements. The TC7107AIPL remains the primary choice for applications requiring exactly 4.6-digit display capability with 5V supply operation. The ICM7228AIPIZ and ICM7228CIPIZ variants are functionally equivalent substitutes when 8-digit capability is acceptable or when supply voltage flexibility (4V ~ 6V range) is advantageous. Both Renesas substitutes offer superior inventory availability and extended lower operating temperature range (-40°C versus -25°C). Selection between ICM7228AIPIZ and ICM7228CIPIZ depends on specific application requirements not specified in the provided parameters; both variants are electrically and mechanically equivalent.

Frequently Asked Questions (FAQ)

Q: Can ICM7228AIPIZ or ICM7228CIPIZ directly replace TC7107AIPL in existing designs?

A: Direct replacement requires verification of pinout compatibility and digit configuration requirements. While all parts are 7-segment LED drivers with through-hole mounting, the TC7107AIPL uses a 40-pin package for 4.6-digit operation, whereas ICM7228 variants use 28-pin packages for 8-digit operation. PCB layout modifications may be necessary.

Q: What is the voltage compatibility between these parts?

A: The TC7107AIPL operates at a fixed 5V supply. The ICM7228AIPIZ and ICM7228CIPIZ operate across a 4V ~ 6V range, which encompasses the 5V requirement. Both substitutes are voltage-compatible with the original part's supply specification.

Q: Are there differences in operating temperature ranges?

A: The TC7107AIPL operates from -25°C to 85°C. The ICM7228AIPIZ and ICM7228CIPIZ extend the lower temperature limit to -40°C, providing broader environmental compatibility. The upper temperature limit of 85°C is identical across all parts.

Q: Do all parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL rating of 1 (Unlimited). Compliance certifications are equivalent across the TC7107AIPL and both ICM7228 variants.

Q: What is the primary functional difference between these parts?

A: The TC7107AIPL is designed for 4.6-digit display applications, while ICM7228AIPIZ and ICM7228CIPIZ support 8-digit configurations. This difference affects package pin count (40-DIP versus 28-DIP) and circuit design requirements.
