ICM7228CIPI LED Driver 7-Segment 8-Digit Display IC

Part Overview

The ICM7228CIPI is a 7-segment, 8-digit LED display driver IC manufactured by Renesas Electronics Corporation in a 28-DIP through-hole package. This component is classified as obsolete, indicating it has been discontinued and is no longer in active production. The part operates with a supply voltage range of 4V to 6V and draws 200 µA of supply current, making it suitable for legacy display applications requiring direct LED segment control.

Due to its obsolete status, sourcing new units from primary manufacturers is no longer available. Finding equivalent or substitute parts is necessary for system maintenance, repair, and redesign efforts where this specific IC was originally specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ICM7228CIPI is evaluated based on the following critical parameters that define functional compatibility:

Primary Substitution Criteria:

• Display Type: LED
• Configuration: 7-Segment
• Digits or Characters: 8 Digits
• Mounting Type: Through Hole
• Package / Case: 28-DIP (0.600", 15.24mm)
• Voltage - Supply Range: Compatibility within or overlapping 4V ~ 6V
• Operating Temperature Range: Coverage of -40°C ~ 85°C or subset thereof

Direct Equivalent: ICM7228CIPIZ is a direct equivalent manufactured by Renesas Electronics Corporation. It maintains identical electrical specifications, package configuration, and functional characteristics as the original ICM7228CIPI, with the distinction of active product status and RoHS3 compliance.

Similar Substitutes: ICM7218CIPI+ is a functionally similar 7-segment, 8-digit LED driver in the same 28-DIP package. While it shares the core display architecture, it operates across a wider supply voltage range (2V ~ 6V) and has a slightly higher supply current specification (250 µA). The operating temperature range differs at -20°C ~ 85°C.

ICL7136CMH+TD is a display driver from Analog Devices Inc./Maxim Integrated with different functional characteristics. It is a 4.6-digit display driver in a 44-MQFP surface-mount package, representing a different product category and mounting technology. This part is not a direct substitute due to package incompatibility and different digit resolution.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: ICM7228CIPIZ is the recommended substitute for ICM7228CIPI. Both parts are manufactured by Renesas Electronics Corporation and maintain identical electrical and mechanical specifications. The primary advantage of ICM7228CIPIZ is its active product status, ensuring continued availability and supply chain reliability. Additionally, ICM7228CIPIZ carries ROHS3 compliance, addressing regulatory requirements for new designs and systems subject to RoHS directives.

For Alternative Consideration: ICM7218CIPI+ is a functionally compatible alternative from Analog Devices Inc./Maxim Integrated. It maintains the same 7-segment, 8-digit LED driver architecture in a 28-DIP through-hole package. The extended supply voltage range (2V ~ 6V) provides greater flexibility in power supply design. However, the slightly elevated supply current (250 µA versus 200 µA) and reduced low-temperature operating limit (-20°C versus -40°C) must be evaluated against specific application requirements.

Not Recommended: ICL7136CMH+TD is not suitable as a substitute for ICM7228CIPI. The incompatible package format (44-MQFP surface-mount versus 28-DIP through-hole), different digit resolution (4.6-digit versus 8-digit), and distinct supply voltage requirement (9V single supply) make this part unsuitable for direct replacement in existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can ICM7228CIPIZ be used as a direct drop-in replacement for ICM7228CIPI? A: Yes. ICM7228CIPIZ is electrically and mechanically identical to ICM7228CIPI. Both parts operate at 4V ~ 6V supply voltage, draw 200 µA supply current, and are packaged in 28-DIP through-hole format. The primary difference is product status and RoHS compliance. No circuit modifications are required.

Q: What is the difference between ICM7228CIPI and ICM7218CIPI+? A: Both are 7-segment, 8-digit LED drivers in 28-DIP packages. ICM7218CIPI+ operates across a wider supply voltage range (2V ~ 6V versus 4V ~ 6V) and has a slightly higher supply current specification (250 µA versus 200 µA). The operating temperature range of ICM7218CIPI+ is -20°C ~ 85°C, which does not cover the full -40°C lower limit of the original part. Substitution is feasible if the application does not require operation below -20°C.

Q: Why is ICL7136CMH+TD listed as a substitute if it is not compatible? A: ICL7136CMH+TD is listed as a similar part from the same manufacturer family but is not a functional substitute. It serves a different application category (4.6-digit display driver) and uses surface-mount packaging. It is included for reference only to distinguish it from true substitutes.

Q: Is RoHS compliance important for selecting a substitute? A: RoHS compliance status depends on application requirements and regulatory jurisdiction. ICM7228CIPIZ and ICM7218CIPI+ are both ROHS3 compliant, making them suitable for applications subject to RoHS directives. The original ICM7228CIPI is RoHS non-compliant and may not meet current procurement or regulatory standards.

Q: Can I use ICM7228CIPIZ in a design originally specified for ICM7228CIPI? A: Yes. ICM7228CIPIZ is the active production equivalent of the obsolete ICM7228CIPI. It is recommended for all new designs and system updates requiring this functionality.

Q: What packaging format is used for each substitute? A: ICM7228CIPI, ICM7228CIPIZ, and ICM7218CIPI+ are all supplied in 28-DIP through-hole packages suitable for breadboard and PCB assembly. ICL7136CMH+TD uses 44-MQFP surface-mount packaging and is not compatible with through-hole PCB designs.
