MPS3563 Equivalent & Substitute Parts

Part Overview

The MPS3563 is a small-signal NPN bipolar junction transistor (BJT) manufactured by onsemi, designed for general-purpose switching and amplification applications. The device features a 12 V collector-emitter breakdown voltage, 50 mA maximum collector current, and 600 MHz transition frequency in a through-hole TO-92 package. The MPS3563 is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain identical electrical characteristics and mechanical compatibility to ensure direct replacement capability.

Substitute Part Grouping Explanation

Substitute parts for the MPS3563 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic requires exact matching of the following parameters:

Transistor type (NPN)
Collector-emitter breakdown voltage (12 V maximum)
Maximum collector current (50 mA)
Collector cutoff current (10 nA maximum)
DC current gain (20 minimum at 8 mA, 10 V)
Maximum power dissipation (350 mW)
Transition frequency (600 MHz)
Operating temperature range (-55°C to 150°C)
Mounting type (Through Hole)
Package configuration (TO-92 / TO-226-3)

The identified substitutes MPS3563RLRA and MPS3563RLRAG satisfy all parametric requirements and maintain mechanical compatibility with the original MPS3563 design. Both alternatives are manufactured by onsemi and feature active product status, distinguishing them from the obsolete original part.

Engineering Selection Recommendations

Both MPS3563RLRA and MPS3563RLRAG provide complete parametric equivalence to the obsolete MPS3563 and are suitable for direct substitution in existing circuit designs. The primary differentiation between the two active alternatives is regulatory compliance status.

MPS3563RLRAG is the preferred selection for new designs and applications requiring RoHS3 compliance. This part satisfies modern environmental and regulatory requirements while maintaining full electrical and mechanical compatibility with the original specification.

MPS3563RLRA remains available as an alternative for applications where RoHS compliance is not a requirement. This part delivers identical electrical performance and mechanical fit.

Both substitutes are manufactured by onsemi and carry active product status, ensuring long-term availability and supply chain stability compared to the obsolete MPS3563.
