Procurement Notes

This component is officially listed as obsolete and no longer manufactured by Renesas Electronics. Verification of availability should focus on secondary market distributors or surplus suppliers rather than direct manufacturer channels. Confirm end-of-life status and lead times carefully when sourcing from third-party vendors.

Selection Notes

Select this part only if legacy compatibility with the 4MX0121 series is required. Note that the specific suffix VA21AVG denotes package and tape/reel variations; verify physical footprint requirements against design constraints. Consider alternative active components if new designs do not mandate this specific obsolete part number.

Part Context

The 4MX0121VA21AVG belongs to the Renesas 4MX0121 family of multiplexer switches. This series is designed for general-purpose signal switching applications requiring low power consumption and fast switching speeds. The device integrates CMOS technology suitable for standard logic voltage domains.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the product is obsolete, engineers must identify functional equivalents based on pinout and electrical specifications from other manufacturers.
