Substitute Part Grouping Explanation

The ICM7228CIPIZ is identified as a substitute based on functional equivalence in 7-segment display driver capability. Both parts serve the core function of driving LED display segments. However, substitution requires careful consideration of the following parameter differences:

Key Substitution Parameters:

• Display Configuration: Both support 7-segment architecture
• Supply Voltage Range: TC7117CKW operates at fixed 5V; ICM7228CIPIZ operates across 4V ~ 6V range
• Digit Capacity: TC7117CKW drives 4.6 digits; ICM7228CIPIZ drives 8 digits
• Mounting Technology: TC7117CKW is Surface Mount (44-MQFP); ICM7228CIPIZ is Through Hole (28-DIP)
• Operating Temperature: TC7117CKW range is 0°C ~ 70°C; ICM7228CIPIZ range is -40°C ~ 85°C
• Current Consumption: ICM7228CIPIZ specified at 200 µA supply current

Parameter Comparison

Engineering Selection Recommendations

Both TC7117CKW and ICM7228CIPIZ maintain Active product status with ROHS3 compliance and REACH Unaffected certification, establishing regulatory equivalence. Selection between these parts depends on application constraints:

The TC7117CKW is appropriate for applications requiring Surface Mount assembly with fixed 5V operation and 4.6-digit display capacity within the 0°C to 70°C temperature window.

The ICM7228CIPIZ is appropriate for applications requiring Through Hole assembly, extended temperature operation (-40°C to 85°C), or 8-digit display capacity. The broader supply voltage range (4V ~ 6V) provides additional flexibility in power supply design.

Substitution feasibility is determined by PCB assembly technology (Surface Mount vs. Through Hole), display digit requirements, and operating temperature specifications of the target application.

Frequently Asked Questions (FAQ)

Q: Can ICM7228CIPIZ directly replace TC7117CKW in an existing design?

A: Direct replacement requires PCB redesign. TC7117CKW uses Surface Mount (44-MQFP) assembly while ICM7228CIPIZ requires Through Hole (28-DIP) footprint. Additionally, ICM7228CIPIZ supports 8 digits versus TC7117CKW's 4.6-digit capacity, requiring firmware or hardware interface modifications.

Q: What are the key electrical differences between these parts?

A: TC7117CKW operates at fixed 5V supply. ICM7228CIPIZ operates across 4V ~ 6V range. Operating temperature ranges differ: TC7117CKW spans 0°C ~ 70°C while ICM7228CIPIZ spans -40°C ~ 85°C. ICM7228CIPIZ specifies 200 µA supply current.

Q: Are both parts compliant with current regulations?

A: Both parts are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: Which part has better moisture handling characteristics?

A: ICM7228CIPIZ has Moisture Sensitivity Level 1 (Unlimited), indicating superior moisture resistance compared to TC7117CKW's MSL 3 (168 Hours). This affects storage and handling requirements.

Q: What mounting technology considerations apply to substitution?

A: TC7117CKW is Surface Mount technology suitable for automated PCB assembly. ICM7228CIPIZ is Through Hole technology requiring manual or selective soldering. Assembly process compatibility must be evaluated before substitution.
