Substitute Part Grouping Explanation
The 7152MI-11LFT qualifies as a parametric equivalent to the ICS7152AMI-11T based on the following critical substitution criteria:
Electrical Parameters: Identical frequency specification (67MHz maximum), matching PLL architecture, identical input/output signal types (Clock input, CMOS output), matching supply voltage range (3V ~ 3.6V), and identical operating temperature range (-40°C ~ 85°C).
Mechanical Parameters: Identical package type (8-SOIC with 0.154" width, 3.90mm), matching surface mount mounting type, and equivalent moisture sensitivity level (MSL 1).
Functional Parameters: Single circuit configuration with 1:1 input-to-output ratio and no differential signaling requirements.
The primary distinction is product status: the ICS7152AMI-11T is Obsolete, while the 7152MI-11LFT is Active, with improved RoHS3 compliance versus non-compliant status of the original part.

Engineering Selection Recommendations
The 7152MI-11LFT is the direct active equivalent for the obsolete ICS7152AMI-11T. Selection of the substitute part is justified by:
Product Status: The 7152MI-11LFT maintains Active status, ensuring continued availability and manufacturer support, whereas the ICS7152AMI-11T is Obsolete and subject to discontinuation.
Compliance: The 7152MI-11LFT is ROHS3 Compliant, meeting current regulatory requirements for electronic components in regulated markets. The original part is RoHS non-compliant.
Electrical and Mechanical Equivalence: All critical parameters—frequency, supply voltage, operating temperature, package type, and circuit configuration—are identical between the two parts, ensuring direct functional substitution without circuit redesign.
Packaging Format: The 7152MI-11LFT is supplied in Tape & Reel format, standard for production environments, compared to bulk packaging of the original part.
Frequently Asked Questions (FAQ)
Q: Can the 7152MI-11LFT be used as a direct replacement for the ICS7152AMI-11T?
A: Yes. Both parts are electrically and mechanically equivalent. They share identical frequency specifications (67MHz), supply voltage range (3V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and package type (8-SOIC). No circuit modifications are required.
Q: What is the primary reason to switch from ICS7152AMI-11T to 7152MI-11LFT?
A: The ICS7152AMI-11T is Obsolete, creating supply and support risks. The 7152MI-11LFT is Active and ROHS3 Compliant, providing regulatory compliance and long-term availability.
Q: Are the packages physically identical?
A: Yes. Both parts use the 8-SOIC package with 0.154" width and 3.90mm dimensions. PCB footprints and mounting procedures are identical.
Q: Does the packaging format (Tape & Reel vs. Bulk) affect compatibility?
A: No. Packaging format affects only handling and storage procedures, not electrical or mechanical performance. The component itself is identical.
Q: What is the moisture sensitivity level for both parts?
A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
Q: Are there any compliance differences between the two parts?
A: Yes. The 7152MI-11LFT is ROHS3 Compliant, while the ICS7152AMI-11T is RoHS non-compliant. Both are REACH Unaffected and classified as EAR99 for export control purposes.
