MPSA92 Equivalent & Substitute Parts

Part Overview

The MPSA92 is an active PNP bipolar junction transistor (BJT) manufactured by Diotec Semiconductor, designed for general-purpose switching and amplification applications. The device is packaged in a TO-92 through-hole configuration and rated for 300 V collector-emitter breakdown voltage with a maximum collector current of 500 mA and power dissipation of 625 mW. This transistor is suitable for low-frequency signal processing and switching circuits operating across an extended temperature range of -55°C to 150°C. Equivalent and substitute parts are identified based on matching electrical specifications, mechanical compatibility, and package standardization to ensure functional interchangeability in circuit designs.

Substitute Part Grouping Explanation

Substitution of the MPSA92 is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Transistor polarity (PNP)
• Maximum collector current (500 mA)
• Collector-emitter breakdown voltage (300 V)
• Saturation voltage characteristics (500 mV @ 2mA, 20mA)
• Collector cutoff current (250 nA ICBO)
• Maximum power dissipation (625 mW)
• Operating temperature range compatibility

Mechanical Compatibility Criteria:

• Package type: TO-92-3 (TO-226AA) through-hole configuration
• Lead formation and pin assignment

The MPSA92 PBFREE manufactured by Central Semiconductor Corp meets all specified electrical parameters and maintains mechanical compatibility through identical TO-92-3 packaging. This substitute part is functionally interchangeable for applications requiring PNP transistor operation within the defined voltage, current, and thermal specifications.

Engineering Selection Recommendations

Primary Selection (Diotec MPSA92): The original Diotec Semiconductor MPSA92 is the primary component specification. This part maintains active product status and is available in high inventory volume (40,455 pcs). The device supports transition frequency of 70 MHz and operates across the full temperature range of -55°C to 150°C.

Substitute Selection (Central Semiconductor MPSA92 PBFREE): The Central Semiconductor MPSA92 PBFREE serves as a direct functional substitute. This part is ROHS3 compliant and REACH unaffected, providing regulatory compliance advantages for applications subject to environmental restrictions. The substitute maintains all critical electrical parameters including 500 mA collector current, 300 V breakdown voltage, and 625 mW power rating. The operating temperature range extends to -65°C minimum, providing enhanced low-temperature performance. The transition frequency specification of 50 MHz is lower than the primary part but remains suitable for general-purpose switching applications. Inventory availability is 8,547 pcs.

Both parts are active products with identical TO-92-3 packaging, ensuring direct mechanical interchangeability in through-hole circuit board applications.

Frequently Asked Questions (FAQ)

Q: Can the MPSA92 PBFREE be used as a direct replacement for the Diotec MPSA92?

A: Yes. Both parts are PNP transistors with identical maximum ratings for collector current (500 mA), collector-emitter breakdown voltage (300 V), saturation voltage (500 mV @ 2mA, 20mA), and power dissipation (625 mW). Both use TO-92-3 through-hole packaging with identical pin configuration. The parts are functionally interchangeable for circuit applications within these specified parameters.

Q: What is the difference in transition frequency between the two parts?

A: The Diotec MPSA92 specifies 70 MHz transition frequency, while the Central Semiconductor MPSA92 PBFREE specifies 50 MHz. For low-frequency switching and general-purpose amplification circuits, this difference does not affect functional performance. Applications requiring operation above 50 MHz should use the Diotec part.

Q: Does the MPSA92 PBFREE offer any compliance advantages?

A: Yes. The Central Semiconductor MPSA92 PBFREE is ROHS3 compliant and REACH unaffected, providing regulatory compliance for applications subject to environmental and hazardous substance restrictions. The Diotec MPSA92 RoHS status is listed as not applicable.

Q: Are the operating temperature ranges compatible?

A: Both parts operate to a maximum of 150°C. The Diotec MPSA92 operates from -55°C to 150°C, while the Central Semiconductor MPSA92 PBFREE operates from -65°C to 150°C. The substitute part provides extended low-temperature capability.

Q: What is the DC current gain specification for each part?

A: The Diotec MPSA92 specifies minimum DC current gain (hFE) of 40 @ 10mA, 10V. The Central Semiconductor MPSA92 PBFREE specifies minimum DC current gain of 25 @ 30mA, 10V. These specifications are measured at different operating points and both parts meet the electrical requirements for PNP transistor operation.

Q: Are both parts available in the same packaging format?

A: Yes. Both the Diotec MPSA92 and Central Semiconductor MPSA92 PBFREE use TO-92-3 (TO-226AA) through-hole packaging with formed leads. The parts are mechanically identical and directly interchangeable on circuit boards designed for TO-92 package footprints.
