MS1003

Overview

The MS1003 is a silicon RF bipolar transistor manufactured by Microchip Technology, designed for VHF mobile applications. The device utilizes silicon technology and is classified under RF Bipolar Transistors. It is currently listed as an End-of-Life (EOL) product with limited availability. The component is packaged in a standard configuration suitable for through-hole or surface mount integration, though specific package dimensions are not detailed in the provided public specifications.

Part Context

This component belongs to the RF Bipolar Transistor category within Microchip's discrete semiconductor portfolio. It was historically utilized in high-frequency communication systems requiring VHF performance characteristics. As an EOL part, it represents legacy technology no longer in active production, primarily serving maintenance or replacement roles in existing equipment designs rather than new development.

Replacement Considerations

Publicly confirmed substitute part numbers for the MS1003 are not available in the provided documentation. Designers should consult official Microchip discontinuance notices or authorized distributor cross-reference tools to identify compatible alternatives that meet VHF mobile application requirements.
