Product Overview
Motorola 48-869571 (marked 9571) is a small-signal silicon PNP bipolar junction transistor housed in a standard TO-92 plastic package. Widely referenced under Motorola equipment schematics as internal type M9571, this component serves legacy land-mobile radio communications gear, mobile extenders, and commercial RF systems. It provides reliable amplification and switching in circuitry engineered for Motorola communications hardware.
Key Features
- Silicon PNP small-signal bipolar junction transistor

- Body marked with Motorola logo and 9571 type designation
- Common functional replacement for MPS3703 and 2N3906 applications
Applications
- Servicing legacy Motorola land-mobile radios and mobile repeater assemblies
- Bench repairs on classic communications transceivers and broadcast audio boards
- Restoring vintage RF and audio processing sections requiring original Motorola components
- Breadboard prototyping for analog synth modules and small-signal discrete PNP stages
Frequently Asked Questions
What equipment originally used the Motorola 48-869571 / M9571 transistor?
Motorola deployed this PNP transistor across various land-mobile communications products, including MICOR series stations, PAC-RT mobile extenders, and specialized broadcast processing gear.
What common general-purpose transistors share functional equivalence?
In standard low-power small-signal circuits, common cross-references include the MPS3703 and 2N3906.
How is this transistor identified compared to similar Motorola small-signal parts?
The flat face of the package is marked with the core designation 9571 directly above the Motorola stylized emblem, distinguishing it from related NPN complementary devices.
Nothing restores a finicky piece of two-way radio iron quite like dropping the exact factory-numbered silicon right back onto the board.
