Engineering Selection Recommendations

The 5P35021B-000NDGI is the manufacturer-recommended substitute for the obsolete 525-01RILF. Both devices are manufactured by Renesas Electronics Corporation and maintain identical compliance certifications (ROHS3, REACH Unaffected, EAR99 ECCN classification). The substitute part is currently in Active product status, ensuring long-term availability and supply chain continuity.

The 5P35021B-000NDGI operates within the temperature range of the original part and maintains PLL with bypass functionality. The substitute supports the required clock and crystal inputs and provides CMOS-compatible output options. The higher maximum frequency (500MHz versus 140MHz) and expanded output format support (LP-HCSL, LVCMOS, LVDS, LVPECL) provide design flexibility for current and future applications.

Package and footprint differences require PCB layout modification. The substitute uses a 20-VFQFN Exposed Pad package compared to the original 28-SSOP package, necessitating schematic and layout updates during design transition.

Frequently Asked Questions (FAQ)

Q: Can the 5P35021B-000NDGI directly replace the 525-01RILF without design changes?

A: The 5P35021B-000NDGI provides equivalent clock generation and distribution functionality but requires design modifications. The package footprint differs (20-VFQFN Exposed Pad versus 28-SSOP), and the input-to-output ratio changes from 1:2 to 2:3. PCB layout and schematic updates are necessary.

Q: What are the key compatibility factors for this substitution?

A: Both devices share the same manufacturer (Renesas Electronics Corporation), operating temperature range (-40°C ~ 85°C), PLL with bypass architecture, and compliance certifications. The substitute supports clock and crystal inputs with CMOS-compatible outputs, meeting the functional requirements of the original part.

Q: Does the supply voltage range differ between these parts?

A: Yes. The 525-01RILF operates at 3V ~ 5.5V, while the 5P35021B-000NDGI supports multiple voltage ranges: 1.71V ~ 1.89V, 2.375V ~ 2.625V, and 3.135V ~ 3.465V. Design verification is required to confirm voltage compatibility with your application.

Q: What is the significance of the different input-to-output ratios?

A: The 525-01RILF provides a 1:2 ratio (one input produces two outputs), while the 5P35021B-000NDGI provides a 2:3 ratio (two inputs produce three outputs). This affects clock distribution architecture and must be evaluated against application requirements.

Q: Are there any packaging considerations for this substitution?

A: Yes. The 525-01RILF uses a 28-pin SSOP package, while the 5P35021B-000NDGI uses a 20-pin QFN package with exposed pad. This requires complete PCB redesign for the clock generation circuit. Both devices are surface-mount components with identical moisture sensitivity levels (MSL 1).

Q: Is the substitute part currently available?

A: The 5P35021B-000NDGI is classified as Active product status with documented inventory availability, ensuring supply continuity. The original 525-01RILF is Obsolete and no longer recommended for new designs.
