Engineering Selection Recommendations

The 5P35021B-000NDGI is the manufacturer-recommended substitute for the obsolete 672M-02ILF. Selection should be based on the following factors:

Product Status: The 5P35021B is an active product with full manufacturer support, ensuring long-term availability and supply chain stability compared to the obsolete 672M-02ILF.

Compliance & Certifications: Both devices maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications.

Thermal & Environmental: Both devices operate across the identical -40°C ~ 85°C temperature range, ensuring compatibility in equivalent thermal environments.

Supply Voltage: The 5P35021B supports 3.135V ~ 3.465V operation, which aligns with the primary operating range of the 672M-02ILF. Applications requiring the full 5.5V upper limit of the 672M-02ILF must verify compatibility with the 5P35021B's maximum 3.465V specification.

Moisture Sensitivity: The 5P35021B features MSL 1 (Unlimited), providing superior moisture tolerance compared to the 672M-02ILF's MSL 3 (168 Hours), reducing handling and storage constraints.

Package Transition: The shift from 16-SOIC to 20-VFQFN requires PCB layout redesign. The 5P35021B's smaller footprint (3x3mm) may provide space optimization benefits in compact designs.

Frequently Asked Questions (FAQ)

Q: Can the 5P35021B-000NDGI directly replace the 672M-02ILF without PCB modifications?

A: No. The 5P35021B uses a 20-VFQFN package versus the 672M-02ILF's 16-SOIC package. PCB layout redesign is required, including footprint changes, trace routing, and via placement adjustments.

Q: What is the primary reason for substitution?

A: The 672M-02ILF is obsolete. The 5P35021B is the manufacturer-recommended active alternative, ensuring continued availability and support.

Q: Are the frequency specifications compatible?

A: Yes. The 5P35021B's 500MHz maximum frequency exceeds the 672M-02ILF's 135MHz requirement, providing operational headroom for clock distribution applications.

Q: What supply voltage should be used for the 5P35021B?

A: The 5P35021B supports multiple voltage rails: 1.71V ~ 1.89V, 2.375V ~ 2.625V, and 3.135V ~ 3.465V. For applications using the 672M-02ILF's 3.13V ~ 5.5V range, the 3.135V ~ 3.465V rail is the compatible option. Applications requiring 5.5V operation must use alternative solutions.

Q: Does the 5P35021B require different handling procedures?

A: The 5P35021B has MSL 1 (Unlimited) versus the 672M-02ILF's MSL 3 (168 Hours). This represents improved moisture tolerance, reducing bake-out requirements and extending shelf life.

Q: What are the input and output differences between these devices?

A: The 672M-02ILF provides CMOS output with 1:4 input-to-output ratio. The 5P35021B supports multiple output types (LP-HCSL, LVCMOS, LVDS, LVPECL) with 2:3 input-to-output ratio and differential output capability, offering greater flexibility for clock distribution architectures.

Q: Is the 5P35021B suitable for all 672M-02ILF applications?

A: Substitution feasibility depends on specific application requirements. Verify supply voltage compatibility, output type requirements, input-to-output ratio needs, and package constraints before implementation.
