Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICM7225IPL+ is determined by the following critical parameters:

Primary Substitution Criteria:

• Display driver functionality (LED or LCD counter/decoder operation)
• Package type compatibility (40-DIP form factor)
• Digit/character count capability (4.5 digits minimum)
• Supply voltage range overlap
• Through-hole mounting compatibility
• RoHS3 compliance and REACH unaffected status

Substitute Parts Identified:

1. ICM7224IPL+ – LCD driver variant with 4.5-digit configuration in 40-DIP package. Active product status. Operates within 3V–6V supply range with 10 µA supply current. Maintains identical package footprint and compliance certifications.

2. ICM7228CIPIZ – LED driver with 8-digit configuration in 28-DIP package. Active product status. Operates within 4V–6V supply range with 200 µA supply current. Reduced pin count due to smaller package; suitable where digit count expansion is acceptable and board space permits package transition.

Parameter Comparison

Engineering Selection Recommendations

ICM7224IPL+ Selection: Choose this substitute when direct form-factor compatibility with the 40-DIP package is required and the application can accommodate LCD display technology in place of LED. This part maintains identical pin count and package dimensions, minimizing PCB redesign. Active product status ensures long-term availability and supply chain stability. RoHS3 compliance and REACH unaffected status align with the original part's regulatory profile.

ICM7228CIPIZ Selection: Choose this substitute when the application permits package transition from 40-DIP to 28-DIP and can utilize 8-digit display capability. This part is manufactured by Renesas Electronics Corporation and maintains active product status. The extended operating temperature range (-40°C to 85°C) provides broader environmental tolerance compared to the ICM7224IPL+. RoHS3 compliance and REACH unaffected status are maintained. Pin count reduction requires PCB layout modification.

Compliance Considerations: All substitute parts maintain ROHS3 compliance, MSL Level 1 (unlimited moisture sensitivity), REACH unaffected status, and EAR99 export classification, ensuring regulatory equivalence with the obsolete ICM7225IPL+.

Frequently Asked Questions (FAQ)

Q: Can ICM7224IPL+ directly replace ICM7225IPL+ without PCB modification? A: Yes. Both parts use identical 40-DIP package dimensions (0.600", 15.24mm) and pin count. Direct socket substitution is possible. However, the display type differs (LCD vs. LED), requiring verification that the application's display interface and drive circuitry support LCD operation.

Q: What is the primary difference between ICM7224IPL+ and ICM7228CIPIZ? A: ICM7224IPL+ maintains the 40-DIP package and 4.5-digit configuration of the original part, while ICM7228CIPIZ uses a 28-DIP package with 8-digit capability. ICM7224IPL+ is an LCD driver; ICM7228CIPIZ is an LED driver. Package transition to ICM7228CIPIZ requires PCB redesign.

Q: Are all substitute parts RoHS3 compliant? A: Yes. ICM7224IPL+ and ICM7228CIPIZ are both ROHS3 compliant with MSL Level 1 (unlimited) moisture sensitivity, matching the original ICM7225IPL+ compliance profile.

Q: Which substitute offers the widest operating temperature range? A: ICM7228CIPIZ operates from -40°C to 85°C, compared to ICM7224IPL+ at -20°C to 85°C. Select ICM7228CIPIZ for applications requiring extended low-temperature operation.

Q: What are the supply voltage requirements for each substitute? A: ICM7224IPL+ operates at 3V–6V with 10 µA supply current. ICM7228CIPIZ operates at 4V–6V with 200 µA supply current. Verify system power supply capability before selection.

Q: Is PCB redesign required to use ICM7228CIPIZ? A: Yes. The 28-DIP package differs from the original 40-DIP form factor, requiring PCB layout modification. Pin assignments must be verified against application schematics before implementation.
