Frequently Asked Questions (FAQ)

Q: Why is the 280G-46LF classified as obsolete?

A: The 280G-46LF has reached end-of-life status with Renesas Electronics Corporation. Obsolete products are no longer manufactured, and manufacturer technical support is discontinued. Transition to active alternatives is necessary for new designs and ongoing production.

Q: Is the 5L35021B-000NDGI a direct pin-for-pin replacement?

A: The 5L35021B-000NDGI is a functional equivalent Clock/Timing IC from the same manufacturer. Pin compatibility must be verified against your specific application schematic and PCB layout, as package types may differ (20-QFN vs. the unspecified packaging of the 280G-46LF).

Q: What are the key differences in specifications?

A: The 5L35021B-000NDGI provides documented specifications including 250MHz maximum frequency, PLL functionality, dual output types (LP-HCSL and LVCMOS), and 1:3 input-to-output ratio. The original 280G-46LF specifications are not fully documented in available data.

Q: Can I use remaining inventory of the 280G-46LF?

A: Existing inventory of 1110 units can be used for current production runs. However, for new designs and long-term production planning, transition to the 5L35021B-000NDGI is recommended to ensure supply chain continuity beyond current stock depletion.

Q: What is the package difference?

A: The 5L35021B-000NDGI uses a 20-VFQFN Exposed Pad package (20-QFN 3x3mm form factor) with Surface Mount mounting type. The 280G-46LF packaging is not specified in available documentation.

Q: Are there compliance or regulatory considerations?

A: The 5L35021B-000NDGI is REACH Unaffected and classified as EAR99 for export control purposes. Moisture Sensitivity Level 1 indicates unlimited shelf life under standard storage conditions.
