ICS9FG108DFILFT Equivalent & Substitute Parts

Part Overview

The ICS9FG108DFILFT is a Clock/Frequency Synthesizer IC manufactured by Renesas Electronics Corporation, designed for Intel CPU Server, PCI Express (PCIe), and SATA applications. This 48-SSOP surface mount device generates a 400MHz output from clock or crystal input using a Phase-Locked Loop (PLL) architecture with a 1:9 input-to-output ratio and HCSL differential output.

The ICS9FG108DFILFT is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for legacy system support, repairs, and production requirements.

Substitute Part Grouping Explanation

Substitution of the ICS9FG108DFILFT is determined by strict equivalence across the following critical parameters:

• Package Compatibility: All substitute parts must use the 48-BSSOP (0.295", 7.50mm Width) surface mount package to ensure PCB layout and assembly compatibility
• Electrical Specifications: Maximum frequency (400MHz), supply voltage range (3.135V ~ 3.465V), and operating temperature range (-40°C ~ 85°C) must be identical
• Functional Architecture: PLL-based frequency synthesis with 1:9 input-to-output ratio and HCSL differential output configuration
• Application Domain: Intel CPU Server, PCI Express (PCIe), and SATA clock generation functionality
• Manufacturer: Renesas Electronics Corporation maintains design and performance consistency across the product family

The substitute parts listed below meet all these criteria and are electrically and mechanically interchangeable with the ICS9FG108DFILFT.

Parameter Comparison

Engineering Selection Recommendations

9FG108EFILFT is the direct manufacturer substitute with active product status. This part is available in Tape & Reel (TR) packaging and carries ROHS3 compliance certification. The Moisture Sensitivity Level (MSL) is rated at 3 (168 Hours), which requires controlled storage and handling conditions during assembly operations.

9FG108EFILF is the manufacturer-recommended substitute with active product status. This part is available in standard packaging and also carries ROHS3 compliance certification with the same MSL rating of 3 (168 Hours).

Both substitute parts are electrically and mechanically equivalent to the ICS9FG108DFILFT. Selection between them depends on packaging requirements: choose 9FG108EFILFT for tape and reel supply chain integration, or 9FG108EFILF for alternative packaging configurations. Both parts meet current regulatory compliance standards (ROHS3, REACH Unaffected, EAR99) and are suitable for new designs and legacy system replacements.

Frequently Asked Questions (FAQ)

Q: Are the 9FG108EFILFT and 9FG108EFILF parts pin-compatible with the ICS9FG108DFILFT?

A: Yes. All three parts use the identical 48-BSSOP package with 0.295" width and 7.50mm dimensions. Pin configuration, spacing, and functionality are equivalent, enabling direct PCB layout compatibility.

Q: What is the difference between 9FG108EFILFT and 9FG108EFILF?

A: The primary difference is packaging format. The 9FG108EFILFT is supplied in Tape & Reel (TR) configuration for automated assembly lines. The 9FG108EFILF is supplied in standard packaging. Both parts are electrically identical and carry the same ROHS3 compliance and MSL rating.

Q: Why do the substitute parts have a higher Moisture Sensitivity Level (MSL) rating?

A: The ICS9FG108DFILFT has MSL 1 (Unlimited), while the substitute parts have MSL 3 (168 Hours). MSL 3 requires that components be stored in controlled humidity conditions and used within 168 hours of package opening. This is a common characteristic of newer manufacturing processes and does not affect electrical performance or long-term reliability when proper handling procedures are followed.

Q: Are the substitute parts suitable for new product designs?

A: Yes. Both 9FG108EFILFT and 9FG108EFILF are active products with current manufacturer support. They are appropriate for new designs requiring Intel CPU Server, PCI Express (PCIe), and SATA clock generation functionality. The ROHS3 compliance and REACH Unaffected status meet current regulatory requirements.

Q: Can I use these parts interchangeably in production?

A: Yes, within the constraints of your supply chain and packaging requirements. Both substitute parts are electrically and mechanically equivalent to the ICS9FG108DFILFT. Ensure that your assembly process accommodates the MSL 3 moisture sensitivity rating through proper component storage and handling.

Q: What certifications and compliance standards apply to these parts?

A: All three parts carry REACH Unaffected status and EAR99 export classification. The substitute parts (9FG108EFILFT and 9FG108EFILF) are ROHS3 compliant. HTSUS classification is 8542.39.0001 for all parts.
