Substitute Part Grouping Explanation

Substitution eligibility for the ICS9FG108DFLFT is determined by strict equivalence across the following critical parameters:

• Manufacturer: Renesas Electronics Corporation
• Output Type: HCSL
• Frequency - Max: 400MHz
• Voltage - Supply: 3.135V ~ 3.465V
• Operating Temperature: 0°C ~ 70°C
• Package / Case: 48-BSSOP (0.295", 7.50mm Width)
• Input Type: Clock, Crystal
• Ratio - Input:Output: 1:9
• Differential - Input:Output: No/Yes
• Number of Circuits: 1
• PLL: Yes
• Main Purpose: Intel CPU Server, PCI Express (PCIe), SATA

The identified substitute parts (9FG108EFLFT and 9FG108EFLF) maintain identical electrical specifications and mechanical compatibility. Differences exist only in product status, packaging format, and compliance certifications, which do not affect functional interchangeability in the target application.

Parameter Comparison

Engineering Selection Recommendations

Both 9FG108EFLFT and 9FG108EFLF are functionally equivalent to the ICS9FG108DFLFT and are suitable for direct substitution in Intel CPU Server, PCI Express (PCIe), and SATA clock generation applications.

The 9FG108EFLFT (Tape & Reel packaging) is recommended for high-volume production environments where automated assembly processes are employed. This part carries Active product status and ROHS3 compliance certification.

The 9FG108EFLF (Tube packaging) is recommended for lower-volume applications, prototype development, or manual assembly workflows. This part also carries Active product status and ROHS3 compliance certification.

Both substitute parts feature improved moisture sensitivity specifications (MSL 3, 168 Hours) compared to the obsolete ICS9FG108DFLFT (MSL 1, Unlimited), reflecting current manufacturing standards. This difference does not impact functional performance in standard operating environments.

Frequently Asked Questions (FAQ)

Q: Can 9FG108EFLFT and 9FG108EFLF be used interchangeably with ICS9FG108DFLFT?

A: Yes. Both parts are electrically and mechanically identical to the ICS9FG108DFLFT. The only differences are product status (Active vs. Obsolete), packaging format (Tape & Reel vs. Tube), and moisture sensitivity level. These differences do not affect functional performance in the target application.

Q: What is the difference between Tape & Reel and Tube packaging?

A: Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly in high-volume manufacturing. Tube packaging is suitable for manual handling and lower-volume applications. Both formats contain the same 48-SSOP component.

Q: Does the MSL difference between the main part and substitutes affect compatibility?

A: No. The MSL rating indicates moisture sensitivity during storage and handling. The substitute parts (MSL 3, 168 Hours) meet current industry standards. Both ratings are compatible with standard PCB assembly processes.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both 9FG108EFLFT and 9FG108EFLF are ROHS3 compliant. The main part (ICS9FG108DFLFT) does not specify RoHS status due to its Obsolete classification.

Q: Which substitute part should I select for new designs?

A: For new designs, either substitute part is acceptable. Select based on your manufacturing process: 9FG108EFLFT for automated assembly (Tape & Reel) or 9FG108EFLF for manual assembly (Tube).
