Key Parameters

Substitute Part Grouping Explanation

Substitution of the 9173B-01CS08LFT is determined by the following critical parameters:

• Functional Category: Clock/Timing generator with PLL capability
• Output Frequency Range: Must support minimum 75MHz operation
• Input/Output Ratio: 1:2 frequency multiplication capability
• Supply Voltage Compatibility: Operating range must accommodate 4.75V ~ 5.25V
• Mounting Type: Surface mount configuration required
• Compliance Standards: ROHS3 compliance maintained

The substitute part 5P49V6967A000NDGI8 qualifies as an equivalent based on these parameters. While it operates at higher maximum frequency (350MHz) and supports broader input/output signal types, it maintains PLL functionality, surface mount packaging, ROHS3 compliance, and the required frequency multiplication capability. The higher frequency ceiling and expanded signal interface options provide enhanced capability for video genlock applications.

Parameter Comparison

Engineering Selection Recommendations

The 5P49V6967A000NDGI8 is the manufacturer-recommended substitute for the obsolete 9173B-01CS08LFT. Both devices are manufactured by Renesas Electronics Corporation and maintain ROHS3 compliance. The substitute part is currently in active production status with available inventory, addressing the obsolescence of the original component.

Key considerations for selection:

• The substitute operates at a lower supply voltage range (1.71V ~ 3.465V) compared to the original (4.75V ~ 5.25V), requiring voltage regulation or power supply modification in existing designs
• The substitute supports an extended operating temperature range (-40°C ~ 85°C) versus the original (0°C ~ 70°C), providing broader environmental capability
• The substitute package is 40-VFQFN Exposed Pad versus the original 8-SOIC, necessitating PCB layout redesign
• The substitute supports multiple input and output signal types (HCSL, LVCMOS, LVDS, LVPECL) compared to the original clock input/output configuration, enabling flexible system integration

Frequently Asked Questions (FAQ)

Q: Can the 5P49V6967A000NDGI8 directly replace the 9173B-01CS08LFT without circuit modifications?

A: Direct pin-for-pin replacement is not possible due to different package types (8-SOIC versus 40-VFQFN Exposed Pad) and different supply voltage requirements. PCB redesign and power supply modifications are necessary.

Q: What is the primary reason for substitution?

A: The 9173B-01CS08LFT is classified as obsolete. The 5P49V6967A000NDGI8 is the manufacturer-recommended active alternative that maintains core clock generation and PLL functionality.

Q: Are both parts compliant with the same regulatory standards?

A: Yes, both parts are ROHS3 compliant and carry EAR99 ECCN classification. Both are REACH unaffected.

Q: What are the key electrical differences between these parts?

A: The substitute operates at lower supply voltage (1.71V ~ 3.465V versus 4.75V ~ 5.25V), supports higher maximum frequency (350MHz versus 75MHz), and provides extended temperature range (-40°C ~ 85°C versus 0°C ~ 70°C).

Q: Does the substitute support the same input/output signal types?

A: No. The original part uses standard clock input/output. The substitute supports HCSL, LVCMOS, LVDS, and LVPECL signal types, providing expanded interface options.

Q: What packaging considerations apply to substitution?

A: The original uses 8-SOIC (0.154", 3.90mm width). The substitute uses 40-VFQFN Exposed Pad (5x5mm), requiring complete PCB layout redesign and different assembly processes.
