MMBTA92 Equivalent & Substitute Parts

Part Overview

The MMBTA92 is an active-status PNP bipolar junction transistor (BJT) manufactured by Good-Ark Semiconductor, designed for surface mount applications in the SOT-23 package. This component operates at a maximum collector current of 200 mA, withstands collector-emitter breakdown voltage of 300 V, and dissipates up to 300 mW of power. The transistor is specified for operating temperatures from -55°C to 150°C and features a transition frequency of 50 MHz.

Equivalent and substitute parts are identified when manufacturers discontinue production, supply constraints occur, or design flexibility is required while maintaining electrical and mechanical compatibility within the specified parameter envelope.

Frequently Asked Questions (FAQ)

Q: Can the MMBTA92 from EVVO Semi be used as a direct replacement for the Good-Ark MMBTA92?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, package dimensions, and compliance certifications. Direct substitution is supported without circuit redesign.

Q: What parameters must match for a part to be considered a substitute for the MMBTA92?

A: Substitutes must match the following: PNP transistor type, 200 mA maximum collector current, 300 V collector-emitter breakdown voltage, 200 mV saturation voltage at specified bias conditions, 250 nA maximum cutoff current, 100 minimum DC current gain, 300 mW maximum power dissipation, 50 MHz transition frequency, surface mount mounting type, SOT-23 package, ROHS3 compliance, and MSL Level 1 rating.

Q: Are there differences in operating temperature ranges between the two manufacturers?

A: The Good-Ark MMBTA92 specifies an operating temperature range of -55°C to 150°C. The EVVO Semi variant specifies a maximum junction temperature of 150°C. Both parts operate within the same upper temperature limit; the Good-Ark specification includes extended lower temperature operation to -55°C.

Q: What is the significance of the SOT-23 package designation?

A: SOT-23 (Small Outline Transistor, 3-pin) is the industry-standard surface mount package for this device class. Both manufacturers use this package, ensuring mechanical and electrical compatibility on PCB layouts designed for the MMBTA92.

Q: Are both parts RoHS compliant?

A: Yes. Both the Good-Ark and EVVO Semi MMBTA92 variants are ROHS3 compliant, meeting European Union Restriction of Hazardous Substances directives.

Q: What does MSL Level 1 (Unlimited) mean for moisture sensitivity?

A: MSL Level 1 indicates the component has unlimited shelf life under normal storage conditions without requiring desiccant packaging or baking procedures prior to assembly. This simplifies inventory management and reduces handling constraints.
