TC7106ACLW Equivalent & Substitute Parts

Part Overview

The TC7106ACLW is a 7-segment display driver IC manufactured by Microchip Technology, designed for 4.6-digit LCD applications. This Surface Mount device in 44-PLCC packaging operates at 9V supply voltage and is actively produced. Finding equivalent or substitute components may be necessary due to supply constraints, inventory availability, or specific application requirements that demand alternative packaging or operating characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC7106ACLW is determined by the following critical parameters:

• Display Driver Function: Both the main part and substitute must support 7-segment display driving capability
• Digit Count: The TC7106ACLW drives 4.6 digits; substitutes may support higher digit counts (4.5 digits) while maintaining backward compatibility
• Supply Voltage: The main part operates at 9V; substitutes with lower voltage ranges (3V ~ 6V) represent a functional alternative for applications with different power budgets
• Mounting Technology: The main part uses Surface Mount (44-PLCC); substitutes using Through Hole (40-DIP) represent a different assembly approach
• Package Type: 44-LCC (J-Lead) versus 40-DIP represents a physical form factor change
• Compliance & Certifications: Both parts must maintain ROHS3 compliance and REACH Unaffected status
• Product Status: Active status ensures ongoing availability and support

Parameter Comparison

Engineering Selection Recommendations

Selection between the TC7106ACLW and ICM7224IPL+ should be based on the following factors:

TC7106ACLW is the primary choice when:

• Surface Mount assembly is required or preferred
• 9V supply voltage is available in the application
• 4.6-digit display resolution meets application requirements
• 44-PLCC package footprint is compatible with PCB design

ICM7224IPL+ is a viable substitute when:

• Through Hole assembly is required or preferred
• Lower supply voltage (3V ~ 6V range) is advantageous for power budget optimization
• 4.5-digit display resolution provides enhanced functionality
• 40-DIP package footprint is compatible with PCB design
• Extended operating temperature range (-20°C ~ 85°C) is required

Both parts maintain Active product status, ROHS3 compliance, and REACH Unaffected certification, ensuring regulatory compliance and ongoing manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can ICM7224IPL+ directly replace TC7106ACLW on the same PCB?

A: No. The ICM7224IPL+ uses a 40-DIP Through Hole package, while the TC7106ACLW uses a 44-PLCC Surface Mount package. PCB redesign is required to accommodate the different package footprint and mounting technology.

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

A: The TC7106ACLW drives 4.6-digit displays at 9V supply, while the ICM7224IPL+ drives 4.5-digit LCD displays at 3V ~ 6V supply. The substitute offers higher digit count and lower voltage operation.

Q: Are both parts RoHS compliant?

A: Yes. Both the TC7106ACLW and ICM7224IPL+ are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: Which part has a wider operating temperature range?

A: The ICM7224IPL+ operates across -20°C ~ 85°C, compared to the TC7106ACLW range of 0°C ~ 70°C. The substitute provides a 50°C wider operating window.

Q: What is the moisture sensitivity difference?

A: The TC7106ACLW has MSL 3 (168 Hours), while the ICM7224IPL+ has MSL 1 (Unlimited). The substitute has lower moisture sensitivity, requiring less stringent handling during storage and assembly.

Q: Can I use ICM7224IPL+ in a 9V application?

A: No. The ICM7224IPL+ is rated for 3V ~ 6V supply voltage and cannot be directly powered at 9V without voltage regulation circuitry.
