ICS9179BF-01 Equivalent & Substitute Parts

Part Overview

The ICS9179BF-01 is a Clock Fanout Buffer (Distribution) IC manufactured by Renesas Electronics Corporation, designed for 1:18 clock distribution at frequencies up to 150 MHz. This component operates with a supply voltage range of 3.135V to 3.465V and is housed in a 48-BSSOP package. The product is currently classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ICS9179BF-01 are qualified based on the following critical parameters that determine functional compatibility:

• Input:Output Ratio: 1:18 (exact match required)
• Package / Case: 48-BSSOP (0.295", 7.50mm Width) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Voltage - Supply: 3.135V ~ 3.465V (exact match required)
• Operating Temperature: 0°C ~ 70°C (exact match required)
• Differential - Input:Output: No/No (exact match required)

The substitute parts CDC318ADL and CDC318ADLR, both manufactured by Texas Instruments, meet all critical electrical and mechanical parameters. Both are active products with improved RoHS3 compliance status, providing a direct functional replacement for the obsolete ICS9179BF-01 in applications requiring 1:18 clock distribution at the specified voltage and temperature ranges.

Parameter Comparison

Engineering Selection Recommendations

Both CDC318ADL and CDC318ADLR provide direct substitution for the obsolete ICS9179BF-01 across all critical electrical and mechanical parameters. The selection between these two Texas Instruments alternatives depends on packaging and supply chain requirements:

CDC318ADL is supplied in Tube packaging and is suitable for applications where standard tube packaging meets procurement specifications.

CDC318ADLR is supplied in Cut Tape (CT) & Digi-Reel® packaging, offering flexibility for automated assembly processes and reel-based component handling.

Both substitute parts carry ROHS3 compliance status, providing improved environmental and regulatory alignment compared to the non-compliant original part. The maximum frequency specification of 100 MHz for both substitutes remains within acceptable operating parameters for applications originally designed for the 150 MHz ICS9179BF-01, provided system clock frequencies do not exceed 100 MHz.

Frequently Asked Questions (FAQ)

Q: Can CDC318ADL or CDC318ADLR directly replace ICS9179BF-01 in existing designs?

A: Yes, both parts meet all critical electrical and mechanical parameters: 1:18 distribution ratio, 48-BSSOP package, 3.135V–3.465V supply voltage, and 0°C–70°C operating temperature range. Pin-to-pin compatibility and functional equivalence are established.

Q: What is the difference between CDC318ADL and CDC318ADLR?

A: Both parts are electrically identical. The difference is packaging format: CDC318ADL uses Tube packaging, while CDC318ADLR uses Cut Tape (CT) & Digi-Reel® packaging. Selection depends on assembly process requirements and supply chain preferences.

Q: Why is the maximum frequency specification lower for the substitute parts?

A: The CDC318ADL and CDC318ADLR are specified at 100 MHz maximum frequency, compared to 150 MHz for the ICS9179BF-01. For applications operating at or below 100 MHz, this specification difference does not impact functionality. Applications requiring operation above 100 MHz require alternative component evaluation.

Q: Are there compliance differences between the original and substitute parts?

A: Yes. The ICS9179BF-01 is RoHS non-compliant, while both CDC318ADL and CDC318ADLR are ROHS3 compliant. Additionally, the substitute parts have a Moisture Sensitivity Level (MSL) of 2 (1 Year) compared to MSL 1 (Unlimited) for the original part, requiring adherence to moisture handling procedures during storage and assembly.

Q: What is the inventory status for these substitute parts?

A: CDC318ADL has 1310 pieces in stock, and CDC318ADLR has 1481 pieces in stock, both classified as new original components in active product status.
