Overview
The Microsemi Corporation 1014-12 is a silicon-based RF bipolar transistor designed for radio frequency applications. The component utilizes a Si technology platform and falls under the category of RF Bipolar Transistors within the broader Transistors sub-category. It is manufactured by Microchip Technology, which acquired Microsemi. The device is currently listed as obsolete or discontinued in public distribution channels.
Feature Summary
- Utilizes silicon technology for RF signal processing
- Designed specifically for radio frequency (RF) applications
Applications
- Radio frequency circuit design
- RF signal amplification
Procurement Notes
The 1014-12 is classified as a discontinued product with no current stock available from major distributors. Verification of availability requires checking secondary market suppliers or legacy inventory holders. Procurement should focus on verifying the authenticity of existing stock due to the component's obsolete status.
Selection Notes
Designers requiring this specific RF bipolar transistor must account for its discontinued status when planning long-term production. Alternative components with similar RF specifications should be evaluated for compatibility. Sourcing strategies should prioritize verified legacy stock providers to ensure supply chain stability for maintenance or low-volume production runs.
Part Context
Microsemi Corporation was acquired by Microchip Technology, leading to the integration of its product lines. The 1014-12 represents a legacy RF component from the Microsemi portfolio. Its classification as an RF bipolar transistor indicates its historical use in specialized high-frequency electronic systems before being superseded by newer technologies or phased out of production.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult official Microchip replacement guides or perform functional equivalence analysis using updated RF bipolar transistor datasheets.
