Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICM7218DIPI+ is determined by the following critical parameters:

Mandatory Matching Parameters:

• Display Type: LED
• Configuration: 7 Segment
• Digits or Characters: 8 Digits
• Mounting Type: Through Hole
• Package / Case: 28-DIP (0.600", 15.24mm)
• Supplier Device Package: 28-PDIP

Allowable Parameter Variations:

• Voltage - Supply: Substitute must support the full 2V ~ 6V range or a subset thereof
• Current - Supply: Substitute specifications must be compatible with system design requirements
• Operating Temperature: Substitute range may be equal to or exceed the primary part range
• Manufacturer: Different manufacturers permitted if all electrical and mechanical parameters align

The substitute parts ICM7228AIPIZ, ICM7228BIPIZ, and ICM7228CIPIZ meet these criteria as 8-digit, 7-segment LED drivers in 28-DIP packages with compatible electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active production status and ROHS3 compliance, ensuring long-term availability and regulatory alignment with the primary ICM7218DIPI+ component.

ICM7228BIPIZ provides the closest electrical match to the ICM7218DIPI+, maintaining identical 250 µA supply current specification while supporting the 4V ~ 6V voltage range. This part is suitable for applications where the lower voltage floor of 4V is acceptable.

ICM7228AIPIZ and ICM7228CIPIZ operate at 200 µA supply current, representing a 20% reduction from the primary part specification. These parts are suitable for power-constrained applications and support the same 4V ~ 6V voltage range.

All substitute parts extend the operating temperature range to -40°C ~ 85°C, providing enhanced low-temperature performance compared to the primary part's -20°C ~ 85°C specification.

Frequently Asked Questions (FAQ)

Q: Can ICM7228AIPIZ, ICM7228BIPIZ, or ICM7228CIPIZ be used as direct replacements for ICM7218DIPI+ in existing designs?

A: Yes, provided the design operates within the 4V ~ 6V supply voltage range. The ICM7218DIPI+ supports 2V ~ 6V operation; designs utilizing voltages below 4V require the primary part or equivalent components with matching lower voltage specifications.

Q: What is the primary difference between ICM7228BIPIZ and ICM7228AIPIZ?

A: ICM7228BIPIZ maintains 250 µA supply current identical to the ICM7218DIPI+, while ICM7228AIPIZ operates at 200 µA. Both support 4V ~ 6V supply voltage and -40°C ~ 85°C operating temperature ranges.

Q: Are all substitute parts available in the same 28-DIP package?

A: Yes. All listed substitute parts use the 28-DIP (0.600", 15.24mm) package, ensuring mechanical compatibility with existing PCB layouts and through-hole mounting requirements.

Q: Do the substitute parts maintain the same RoHS and compliance certifications?

A: Yes. All substitute parts are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the primary part's regulatory and environmental specifications.

Q: What inventory levels are available for substitute parts?

A: ICM7228AIPIZ: 1207 units; ICM7228BIPIZ: 2200 units; ICM7228CIPIZ: 1668 units. All parts are new original stock.
