Key Parameters

Substitute Part Grouping Explanation

Substitution of the ICM7225RIPL is based on the following critical parameters that define functional compatibility:

Primary Substitution Criteria:

• Display Type: LED
• Configuration: 7-Segment
• Voltage Supply Range: 4V ~ 6V
• Mounting Type: Through Hole
• Package Type: DIP format

The ICM7228CIPIZ qualifies as a substitute based on matching display type, 7-segment configuration, and compatible supply voltage range. Both components operate within the 4V to 6V supply voltage window and utilize through-hole DIP packaging. The substitute maintains the same functional category as a LED driver for segment display applications.

Parameter Comparison

Engineering Selection Recommendations

The ICM7228CIPIZ is available as an active product from Renesas Electronics Corporation, whereas the ICM7225RIPL is obsolete. The substitute component maintains compatibility in display type (LED), configuration (7-segment), and supply voltage range (4V ~ 6V). Both components utilize through-hole DIP packaging with matching 0.600" (15.24mm) pitch specifications.

The ICM7228CIPIZ offers ROHS3 compliance, addressing regulatory requirements that the original ICM7225RIPL does not meet. The substitute operates across an extended temperature range (-40°C to 85°C versus -20°C to 85°C) and features reduced supply current consumption (200 µA versus 200 mA). The ICM7228CIPIZ supports 8-digit display capability compared to the 4.5-digit capability of the original part.

Frequently Asked Questions (FAQ)

Q: Can the ICM7228CIPIZ directly replace the ICM7225RIPL in existing designs?

A: Both components share the same supply voltage range (4V ~ 6V), 7-segment LED display configuration, and through-hole DIP packaging format. However, the ICM7228CIPIZ operates with 8-digit capability versus the 4.5-digit specification of the ICM7225RIPL, and features different pin counts (28-DIP versus 40-DIP). Circuit-level evaluation is required to confirm functional compatibility.

Q: What are the key differences between these two components?

A: The primary differences are product status (active versus obsolete), RoHS compliance (ROHS3 compliant versus non-compliant), digit capacity (8 digits versus 4.5 digits), supply current (200 µA versus 200 mA), package pin count (28-DIP versus 40-DIP), and operating temperature range (-40°C to 85°C versus -20°C to 85°C).

Q: Are both components available in the same package format?

A: Both utilize through-hole DIP packaging with 0.600" (15.24mm) pitch. However, the ICM7225RIPL uses 40-DIP packaging while the ICM7228CIPIZ uses 28-DIP packaging, resulting in different physical dimensions and pin configurations.

Q: What is the significance of the RoHS compliance difference?

A: The ICM7228CIPIZ meets ROHS3 compliance standards, while the ICM7225RIPL is RoHS non-compliant. This distinction is relevant for applications subject to regulatory requirements restricting hazardous substances in electronic components.
