Procurement Notes
This component is listed as obsolete or end-of-life by the manufacturer. Availability is restricted, and it may not be actively stocked by major distributors. Engineers should verify current supply status and consider lifecycle management strategies when sourcing this part for new designs.
Selection Notes
Designers requiring a 30V varactor with approximately 26pF capacitance in a TO-92-2 package should evaluate this specific part number. Due to its obsolete status, alternative components with similar electrical specifications and compatible pinouts must be identified for long-term production viability.
Part Context
The MV2109RLRA belongs to the varactor diode category within onsemi's discrete semiconductor portfolio. Varactors are specialized diodes that exploit the variable capacitance of a reverse-biased p-n junction. This specific model represents a legacy component previously used in analog RF design before newer surface-mount alternatives became prevalent.
Replacement Considerations
As the MV2109RLRA is obsolete, direct substitutes must be sourced from other manufacturers or updated onsemi series. Verify that replacement parts match the 30V reverse voltage, 26pF capacitance, and TO-92-2 package dimensions to ensure mechanical and electrical compatibility.
