ICS9FG104DGILF Equivalent & Substitute Parts

Part Overview

The ICS9FG104DGILF is a Clock/Frequency Synthesizer IC manufactured by Renesas Electronics Corporation, designed for Intel CPU Server, PCI Express (PCIe), and SATA applications. This 28-TSSOP surface mount device generates a 400MHz output from clock or crystal input using phase-locked loop (PLL) technology with spread spectrum clock generation capabilities.

The ICS9FG104DGILF is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this timing generator.

Substitute Part Grouping Explanation

Substitute parts for the ICS9FG104DGILF are qualified based on strict equivalence across the following critical parameters:

• Identical package type: 28-TSSOP surface mount
• Matching frequency specification: 400MHz maximum output
• Equivalent supply voltage range: 3.135V ~ 3.465V
• Same output configuration: HCSL, single circuit, 1:5 input:output ratio
• Identical operating temperature range: -40°C ~ 85°C
• Matching input type: Clock or Crystal
• Same differential input/output capability: No/Yes
• Equivalent moisture sensitivity: MSL 1 (Unlimited)

The substitute parts identified below maintain full electrical and mechanical compatibility with the original ICS9FG104DGILF specification.

Parameter Comparison

Engineering Selection Recommendations

Both 9FG104EGILF and 9FG104EGILFT are direct substitutes for the obsolete ICS9FG104DGILF, with all electrical and mechanical parameters matching the original specification.

The 9FG104EGILFT is the manufacturer-recommended substitute, offering superior supply availability (18,300 units in stock) and active product status with ROHS3 compliance. This part is supplied in Cut Tape and Digi-Reel® packaging, suitable for high-volume automated assembly operations.

The 9FG104EGILF provides an alternative substitute with active product status and ROHS3 compliance, available in Tube packaging (1,495 units in stock). This option is suitable for lower-volume applications or manual assembly processes.

Both substitutes maintain full compatibility with existing PCB designs, assembly processes, and system performance requirements for Intel CPU Server, PCI Express (PCIe), and SATA clock generation applications.

Frequently Asked Questions (FAQ)

Q: Are the 9FG104EGILF and 9FG104EGILFT electrically identical to the ICS9FG104DGILF?

A: Yes. Both substitute parts maintain identical electrical specifications including 400MHz maximum frequency output, 3.135V ~ 3.465V supply voltage range, HCSL output type, 1:5 input:output ratio, and -40°C ~ 85°C operating temperature range.

Q: What is the difference between 9FG104EGILF and 9FG104EGILFT?

A: The primary difference is packaging format. The 9FG104EGILF is supplied in Tube packaging, while the 9FG104EGILFT is supplied in Cut Tape and Digi-Reel® format. Both are electrically and mechanically identical. The 9FG104EGILFT is the manufacturer-recommended option with higher inventory availability.

Q: Can I use these substitutes as direct replacements on existing PCBs?

A: Yes. Both substitute parts use the identical 28-TSSOP package with matching pinout, footprint, and mechanical dimensions (0.173", 4.40mm Width). No PCB redesign is required.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both 9FG104EGILF and 9FG104EGILFT are ROHS3 compliant. The original ICS9FG104DGILF is REACH Unaffected, and all three parts maintain REACH Unaffected status.

Q: What is the MSL rating for these parts?

A: All three parts carry MSL 1 (Unlimited) moisture sensitivity level, indicating no special moisture control requirements during storage or handling.

Q: Which substitute should I select for new designs?

A: The 9FG104EGILFT is recommended for new designs due to manufacturer recommendation status, active product status, and superior supply availability. This part is optimized for high-volume production with Cut Tape and Digi-Reel® packaging.
