Substitute Part Grouping Explanation

Substitution eligibility for the ICS9FG104DGLF is determined by strict equivalence across the following critical parameters:

• Package and Pinout: 28-TSSOP surface mount package with identical physical dimensions (0.173", 4.40mm Width)
• Output Frequency: 400MHz maximum frequency
• Output Signal Type: HCSL differential output
• Input Configuration: Clock or Crystal input capability
• Frequency Ratio: 1:5 input-to-output ratio
• Supply Voltage Range: 3.135V ~ 3.465V
• Operating Temperature Range: 0°C ~ 70°C
• PLL Functionality: Phase-Locked Loop architecture required
• Application Domain: Intel CPU Server, PCIe, and SATA clock generation

The substitute part 9FG104EGLF meets all these criteria and maintains functional and electrical equivalence with the original ICS9FG104DGLF.

Parameter Comparison

Engineering Selection Recommendations

The 9FG104EGLF is a direct functional equivalent to the ICS9FG104DGLF with identical electrical and mechanical specifications. The primary distinction is product lifecycle status: the ICS9FG104DGLF is Obsolete, while the 9FG104EGLF maintains Active status from Renesas Electronics Corporation.
