TC7117ACKW Equivalent & Substitute Parts

Part Overview

The TC7117ACKW is a 7-segment, 4.6-digit LED driver IC manufactured by Microchip Technology in a 44-MQFP surface mount package. This component is designed for direct drive applications of seven-segment LED displays and is currently in active production status. Substitute parts are identified when equivalent functional performance is required but alternative packaging, mounting technology, or supply voltage ranges are acceptable within system design constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC7117ACKW is determined by functional equivalence in 7-segment LED driver capability. The identified substitute parts (ICM7228AIPIZ and ICM7228CIPIZ) share the following critical parameters:

• 7-segment display driver functionality
• LED driver architecture
• Active product status with current manufacturing support
• ROHS3 compliance and REACH unaffected status
• Supply voltage compatibility within acceptable operating ranges (4V ~ 6V encompasses the 5V requirement)

Key differences that define substitution boundaries:

• Digit capacity: TC7117ACKW drives 4.6 digits; ICM7228 series drives 8 digits
• Package technology: TC7117ACKW uses surface mount (44-QFP); ICM7228 series uses through-hole (28-DIP)
• Mounting method: Surface mount versus through-hole assembly
• Operating temperature range: TC7117ACKW (0°C ~ 70°C) versus ICM7228 series (-40°C ~ 85°C)
• Moisture sensitivity: TC7117ACKW (MSL 3) versus ICM7228 series (MSL 1)

Parameter Comparison

Engineering Selection Recommendations

Selection between TC7117ACKW and substitute parts ICM7228AIPIZ or ICM7228CIPIZ is determined by assembly technology and environmental requirements:

TC7117ACKW is appropriate for:

• Surface mount assembly processes
• Applications requiring 4.6-digit display capability
• Operating environments within 0°C ~ 70°C range
• Designs with MSL 3 moisture sensitivity tolerance

ICM7228AIPIZ and ICM7228CIPIZ are appropriate for:

• Through-hole assembly processes
• Applications requiring 8-digit display capability
• Operating environments within -40°C ~ 85°C range
• Designs with MSL 1 moisture sensitivity requirements
• Supply voltage range 4V ~ 6V

All three parts maintain active product status, ROHS3 compliance, and REACH unaffected status, ensuring regulatory alignment and manufacturing continuity.

Frequently Asked Questions (FAQ)

Q: Can ICM7228AIPIZ or ICM7228CIPIZ directly replace TC7117ACKW in existing designs?

A: Direct replacement requires design modification. The ICM7228 series uses through-hole mounting (28-DIP) versus the TC7117ACKW surface mount (44-QFP), necessitating PCB layout changes. Additionally, the ICM7228 series drives 8 digits compared to the TC7117ACKW's 4.6-digit capability.

Q: What are the key differences in supply voltage between these parts?

A: TC7117ACKW operates at 5V fixed supply. ICM7228AIPIZ and ICM7228CIPIZ operate across 4V ~ 6V range, providing broader voltage tolerance. Both are compatible with 5V supply systems.

Q: How do operating temperature ranges affect substitution decisions?

A: TC7117ACKW operates 0°C ~ 70°C; ICM7228 series operates -40°C ~ 85°C. For applications requiring extended low-temperature operation below 0°C or high-temperature operation above 70°C, the ICM7228 series is required.

Q: What is the significance of Moisture Sensitivity Level (MSL) differences?

A: TC7117ACKW has MSL 3 (168-hour floor life); ICM7228 series has MSL 1 (unlimited floor life). MSL 1 components tolerate longer storage and handling periods without baking requirements, reducing manufacturing process constraints.

Q: Are ICM7228AIPIZ and ICM7228CIPIZ functionally equivalent to each other?

A: Yes. Both parts share identical electrical specifications, package type (28-DIP), and performance parameters. Differences are limited to manufacturer part number designation and internal die variants, which do not affect functional equivalence.
