Key Parameters

Substitute Part Grouping Explanation

Substitution of the 552R-01LNT is determined by the following critical parameters:

• Frequency capability: Maximum operating frequency of 200 MHz or greater
• Input-to-output ratio: 1:8 distribution configuration
• Supply voltage compatibility: Operating range that accommodates 3V to 5.5V systems
• Output logic family: CMOS or compatible logic levels
• Mounting and package form factor: Surface mount technology with compatible pinout and thermal characteristics
• Manufacturer support: Active product status with current manufacturing and supply chain availability

The 5P83908NDGK8 qualifies as a functional substitute based on matching frequency, ratio, and output distribution characteristics, with enhanced supply voltage flexibility and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The 5P83908NDGK8 is an active product with current manufacturing support from Renesas Electronics Corporation, providing supply chain continuity for the obsolete 552R-01LNT. Both devices share identical frequency and distribution ratio specifications (200 MHz, 1:8).

Key considerations for selection:

Supply Voltage Range: The 5P83908NDGK8 operates at 1.71V to 3.465V, which is narrower than the original 3V to 5.5V range. Systems requiring operation above 3.465V require voltage regulation or alternative solutions.

Package Transition: The substitute uses a 20-VFQFN Exposed Pad package (3x3mm) versus the original 20-SSOP package. PCB layout and thermal management characteristics differ; board redesign may be necessary.

Temperature Range: The 5P83908NDGK8 extends operating temperature to -40°C to 105°C, exceeding the original 0°C to 70°C specification.

Compliance: The 5P83908NDGK8 carries ROHS3 compliance certification, supporting modern regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5P83908NDGK8 directly replace the 552R-01LNT without PCB modifications?

A: No. The package types differ (20-SSOP versus 20-VFQFN Exposed Pad), requiring PCB layout changes. Pinout compatibility must be verified against detailed datasheets before implementation.

Q: What is the primary functional difference between these parts?

A: The 552R-01LNT is a Clock Generator with integrated PLL functionality. The 5P83908NDGK8 is a Fanout Buffer designed for clock distribution. Both deliver 1:8 output distribution at 200 MHz, but the internal architecture differs.

Q: Is the 5P83908NDGK8 suitable for 5V supply applications?

A: No. The maximum supply voltage for the 5P83908NDGK8 is 3.465V. Systems requiring 5V operation cannot use this substitute without external voltage regulation.

Q: What are the implications of the package change?

A: The transition from 20-SSOP to 20-VFQFN Exposed Pad affects PCB footprint, trace routing, thermal dissipation characteristics, and assembly processes. Design validation is required.

Q: Does the substitute meet current environmental compliance standards?

A: Yes. The 5P83908NDGK8 is ROHS3 compliant, meeting current regulatory requirements for hazardous substance restrictions.

Q: Are both parts from the same manufacturer?

A: Yes. Both the 552R-01LNT and 5P83908NDGK8 are manufactured by Renesas Electronics Corporation, ensuring consistent design philosophy and support infrastructure.
