Procurement Notes

This component has been transitioned to End of Life status by Central Semiconductor Corp. The manufacturer indicates that no direct replacement part numbers are available for this specific model. Procurement is currently limited to existing stock only. Customers are advised to contact the engineering team at [email protected] for assistance in locating alternate sources or technical data regarding suitable substitutes.

Selection Notes

Designers should verify the required intrinsic standoff ratio and current specifications against the CMPP6027R datasheet before selection. Due to the End of Life status, availability is restricted to remaining inventory. Alternative components must be evaluated for pin compatibility with the SOT-23 package and thermal resistance characteristics matching the 450 °C/W rating under standard PCB mounting conditions.

Part Context

The CMPP6027R belongs to the CMPP6027R/CMPP6028R series of surface-mount silicon programmable unijunction transistors. These devices share similar packaging and operational principles but differ in specific programmable electrical parameters such as peak and valley currents. The series is designed for applications requiring precise control over timing intervals through external resistor programming.

Replacement Considerations

No official replacement part numbers are listed by the manufacturer. The documentation explicitly states N/A for replacements, indicating that customers must source alternative components independently or utilize existing stock.
