ICS7152MI-11T Equivalent & Substitute Parts

Part Overview

The ICS7152MI-11T is a Spread Spectrum Clock Generator IC manufactured by Renesas Electronics Corporation, designed for 67MHz clock generation in 8-SOIC surface mount packaging. This part is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement continuity. The device generates CMOS output from a clock input using an integrated Phase-Locked Loop (PLL) with multiplier capability, operating across the industrial temperature range of -40°C to 85°C with a 3V to 3.6V supply voltage.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ICS7152MI-11T is determined by strict equivalence across the following critical parameters:

• Frequency specification: Maximum output frequency of 67MHz
• Output configuration: CMOS output from clock input
• PLL architecture: Integrated Phase-Locked Loop with multiplier function
• Input/Output ratio: 1:1 ratio maintained
• Supply voltage range: 3V to 3.6V operation
• Temperature range: -40°C to 85°C industrial specification
• Package type: 8-SOIC surface mount form factor with 0.154" (3.90mm) width
• Circuit count: Single circuit configuration

The substitute part 7152MI-11LFT meets all these electrical and mechanical parameters identically. The primary distinction is packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete), with improved RoHS3 compliance in the substitute.

Parameter Comparison

Engineering Selection Recommendations

The 7152MI-11LFT is a direct functional equivalent to the ICS7152MI-11T with identical electrical specifications and mechanical compatibility. Selection of the substitute part is supported by:

• Product status alignment: The substitute maintains active production status, ensuring long-term availability and supply chain stability compared to the obsolete main part.
• Regulatory compliance: The 7152MI-11LFT achieves ROHS3 compliance, meeting current environmental and regulatory requirements, whereas the main part does not.
• Packaging efficiency: Tape & Reel packaging of the substitute accommodates automated assembly processes more effectively than bulk packaging.
• Electrical equivalence: All functional parameters, including frequency, supply voltage, temperature range, and output characteristics, are identical between both parts.

For new designs or production transitions, the 7152MI-11LFT is the appropriate selection. For legacy system maintenance requiring the exact original part number, the ICS7152MI-11T remains available in current inventory.

Frequently Asked Questions (FAQ)

Q: Can the 7152MI-11LFT be used as a direct replacement for the ICS7152MI-11T in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The 8-SOIC package dimensions, pin configuration, frequency output, supply voltage requirements, and temperature operating range are equivalent. No circuit modifications are required.

Q: What is the difference between the two part numbers?

A: The primary differences are product status (Obsolete versus Active), RoHS compliance level (non-compliant versus ROHS3 Compliant), and packaging format (Bulk versus Tape & Reel). The electrical and functional specifications are identical.

Q: Why is the main part listed as obsolete?

A: Obsolescence indicates that the manufacturer has discontinued production of the ICS7152MI-11T. The 7152MI-11LFT represents the current production equivalent from Renesas Electronics Corporation.

Q: Are there any pin compatibility concerns when substituting these parts?

A: No. Both parts use the 8-SOIC (0.154", 3.90mm Width) package with identical pin assignments. PCB footprints and assembly processes remain unchanged.

Q: Does the Tape & Reel packaging of the substitute affect performance?

A: No. Tape & Reel is a packaging and delivery format only. It does not affect the electrical performance, reliability, or functional characteristics of the component itself.

Q: What is the significance of the RoHS3 compliance difference?

A: ROHS3 compliance indicates adherence to current environmental regulations restricting hazardous substances. For applications subject to regulatory requirements or customer specifications mandating RoHS compliance, the 7152MI-11LFT is the appropriate selection.
