TC7106ACKW Equivalent & Substitute Parts

Part Overview

The TC7106ACKW is a 7-segment display driver IC manufactured by Microchip Technology, designed for 4.6-digit display applications. This surface-mount component operates at 9V supply voltage and is housed in a 44-MQFP package. The device is currently in active production status with ROHS3 compliance and MSL-3 moisture sensitivity rating. Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameters for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TC7106ACKW is evaluated based on the following critical parameters:

• Display Driver Function: 7-segment display driver capability
• Digit Count: 4.6-digit or higher display support
• Supply Voltage Compatibility: Operating voltage range must accommodate the application requirements
• Package Type: Physical form factor and mounting compatibility
• Product Status: Active production status ensures availability and support
• Compliance Standards: ROHS3 and REACH compliance for regulatory alignment

The identified substitute ICM7224IPL+ operates as a 7-segment display driver with 4.5-digit capability, exceeding the digit requirement of the main part. However, this substitute operates at 3V–6V supply voltage and uses through-hole mounting (40-DIP), which differs from the surface-mount 44-QFP configuration of the TC7106ACKW. Substitution is valid only when the application design accommodates these electrical and mechanical differences.

Parameter Comparison

Engineering Selection Recommendations

Both the TC7106ACKW and ICM7224IPL+ maintain active product status and ROHS3 compliance, ensuring regulatory alignment and supply chain continuity. The TC7106ACKW is the primary selection for applications requiring surface-mount integration in a 44-QFP footprint with 9V supply operation. The ICM7224IPL+ serves as a substitute only when the application design permits through-hole mounting, operates within the 3V–6V supply range, and requires extended temperature operation (-20°C to 85°C). Pin-to-pin compatibility and functional equivalence must be verified at the circuit design level before implementation.

Frequently Asked Questions (FAQ)

Q: Can the ICM7224IPL+ directly replace the TC7106ACKW in an existing PCB design?

A: No. The ICM7224IPL+ uses through-hole mounting (40-DIP) while the TC7106ACKW uses surface-mount (44-QFP). PCB layout and footprint modifications are required. Additionally, the supply voltage range differs (3V–6V vs. 9V), requiring circuit redesign.

Q: What are the key differences in display capability between these parts?

A: The TC7106ACKW supports 4.6-digit displays, while the ICM7224IPL+ supports 4.5-digit displays. Both are 7-segment drivers. The ICM7224IPL+ provides higher digit capacity, making it suitable for applications requiring additional display resolution.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the TC7106ACKW and ICM7224IPL+ are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the significance of the MSL rating difference?

A: The TC7106ACKW has MSL-3 (168-hour moisture sensitivity limit), while the ICM7224IPL+ has MSL-1 (unlimited). MSL-1 components are less sensitive to moisture absorption during storage and handling, reducing risk during manufacturing processes.

Q: Which part should be selected for new designs?

A: For new surface-mount designs operating at 9V, the TC7106ACKW is the appropriate selection. For through-hole designs operating at 3V–6V with extended temperature requirements, the ICM7224IPL+ is suitable. Selection depends on application-specific electrical and mechanical constraints.
