TC7106CLW Equivalent & Substitute Parts

Part Overview

The TC7106CLW is a 7-segment display driver IC manufactured by Microchip Technology, designed for 4.6-digit display applications. This Surface Mount device operates at 9V supply voltage and is housed in a 44-PLCC package. The part is currently Active in product status and maintains full ROHS3 compliance. Substitute parts are identified when equivalent functional capability is required due to inventory constraints, end-of-life considerations, or application-specific packaging preferences.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC7106CLW is based on the following critical parameters:

• Display Driver Function: Both parts are 7-segment display drivers
• Digit Configuration: TC7106CLW supports 4.6-digit displays; ICM7224IPL+ supports 4.5-digit displays
• Supply Voltage Compatibility: TC7106CLW operates at 9V; ICM7224IPL+ operates at 3V ~ 6V
• Package Technology: TC7106CLW uses Surface Mount (44-PLCC); ICM7224IPL+ uses Through Hole (40-DIP)
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH Unaffected status

The ICM7224IPL+ is identified as a manufacturer-recommended substitute when application requirements permit operation within the 3V ~ 6V supply range and accommodate the Through Hole mounting configuration and expanded digit capacity.

Parameter Comparison

Engineering Selection Recommendations

Both the TC7106CLW and ICM7224IPL+ maintain Active product status and full regulatory compliance under ROHS3 and REACH standards. Selection between these parts is determined by application-specific requirements:

The TC7106CLW is the primary choice for applications requiring 9V supply operation, Surface Mount assembly, and 4.6-digit display capability within the 0°C ~ 70°C operating range.

The ICM7224IPL+ is applicable when the application permits 3V ~ 6V supply voltage operation, Through Hole mounting configuration, and requires 4.5-digit display capacity. This substitute offers extended operating temperature range (-20°C ~ 85°C) and superior moisture handling (MSL 1 versus MSL 3).

Frequently Asked Questions (FAQ)

Q: Can ICM7224IPL+ directly replace TC7106CLW in existing designs?

A: Direct replacement requires verification of three critical factors: supply voltage compatibility (application must operate within 3V ~ 6V range), mounting technology compatibility (PCB must support Through Hole versus Surface Mount), and digit capacity requirements (application must accommodate 4.5-digit versus 4.6-digit output).

Q: What are the key differences in package technology?

A: TC7106CLW uses 44-PLCC Surface Mount packaging (16.59x16.59mm), while ICM7224IPL+ uses 40-DIP Through Hole packaging (0.600", 15.24mm). These represent fundamentally different assembly methods and PCB footprints.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both TC7106CLW and ICM7224IPL+ maintain ROHS3 compliance and REACH Unaffected status, meeting current environmental and hazardous substance regulations.

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

A: TC7106CLW carries MSL 3 (168-hour moisture sensitivity), requiring controlled storage and handling. ICM7224IPL+ carries MSL 1 (unlimited moisture sensitivity), permitting standard storage conditions without moisture-controlled packaging requirements.

Q: Which part offers better temperature performance?

A: ICM7224IPL+ operates across -20°C ~ 85°C, providing 50°C additional low-temperature capability and 15°C additional high-temperature capability compared to TC7106CLW (0°C ~ 70°C).
