Procurement Notes
Verify component status as the EC2C01C-TR is listed as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary markets if procurement is required. Ensure compatibility with existing 2-ECSP1008 footprints and validate electrical parameters against current design specifications before integration.
Selection Notes
Select this component when a small-signal varactor with low capacitance is required for high-frequency applications. The 15 V reverse voltage rating suits low-voltage RF environments. Consider the obsolete status and evaluate alternative varactors with similar capacitance ratios and package dimensions for new designs to ensure long-term supply stability.
Part Context
This part belongs to onsemi’s discrete diode portfolio, specifically within the varactor category. Varactors are essential components in radio frequency systems for adjusting resonance frequencies via voltage changes. The EC2C01C-TR represents a standard solution for compact RF tuning needs, though its obsolescence places it in legacy product lines rather than active development streams.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Due to the obsolete status, engineers should consult onsemi’s official replacement guides or contact sales for recommended equivalents with matching 2-ECSP1008 packages and similar capacitance profiles.
