Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMBTH81_F080 is determined by electrical and mechanical parameter equivalence. The following parameters establish substitution validity:

Electrical Parameters:

• Transistor Type: PNP
• Voltage - Collector Emitter Breakdown (Max): 20V
• Frequency - Transition: 600MHz
• Power - Max: 225mW
• Current - Collector (Ic) (Max): 50mA
• DC Current Gain (hFE) (Min) @ Ic, Vce: 60 @ 5mA, 10V
• Operating Temperature Range: -55°C to 150°C (TJ)

Mechanical Parameters:

• Package / Case: TO-236-3, SC-59, SOT-23-3
• Mounting Type: Surface Mount
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts meeting all these criteria are electrically and mechanically interchangeable with the MMBTH81_F080.

Parameter Comparison

Engineering Selection Recommendations

The MMBTH81_F080 is classified as obsolete. The MMBTH81 is the direct equivalent substitute, carrying active product status from the same manufacturer (onsemi).

Selection Basis:

The MMBTH81 provides identical electrical performance across all specified parameters: 20V collector-emitter breakdown voltage, 600MHz transition frequency, 225mW power dissipation, 50mA maximum collector current, and 60 minimum DC current gain at specified conditions. The operating temperature range (-55°C to 150°C) and mechanical packaging (SOT-23-3 surface mount) are identical.

The MMBTH81 is ROHS3 compliant and carries EAR99 ECCN classification, compared to the obsolete MMBTH81_F080. The substitute part is available in higher inventory quantities (15,400 pieces) with active product status, ensuring long-term supply chain reliability.

Both parts share identical moisture sensitivity level (MSL 1 - Unlimited) and REACH unaffected status, confirming regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: Can the MMBTH81 directly replace the MMBTH81_F080 in existing designs?

A: Yes. The MMBTH81 is electrically and mechanically equivalent to the MMBTH81_F080. All electrical parameters, operating temperature range, and package specifications are identical. The MMBTH81 is the active production equivalent.

Q: What is the difference between MMBTH81_F080 and MMBTH81?

A: The MMBTH81_F080 is an obsolete variant. The MMBTH81 is the current active production part from onsemi with identical electrical and mechanical specifications. The primary difference is product status and availability.

Q: Are there packaging differences between these parts?

A: No. Both parts use identical SOT-23-3 surface mount packaging (also designated TO-236-3 or SC-59). Both are surface mount components with identical footprints and land patterns.

Q: What are the key electrical parameters that define substitution?

A: Substitution is determined by: PNP transistor type, 20V maximum collector-emitter breakdown voltage, 600MHz transition frequency, 225mW maximum power dissipation, 50mA maximum collector current, and 60 minimum DC current gain at 5mA and 10V. All these parameters are identical between the MMBTH81_F080 and MMBTH81.

Q: Is the MMBTH81 RoHS compliant?

A: Yes. The MMBTH81 is ROHS3 compliant. The obsolete MMBTH81_F080 does not carry RoHS certification information.

Q: What is the moisture sensitivity level for these parts?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are there supply chain advantages to using the MMBTH81 over the MMBTH81_F080?

A: Yes. The MMBTH81 is in active production with 15,400 pieces in stock, compared to the obsolete MMBTH81_F080 with 834 pieces. The active status ensures continued availability and supply chain reliability.
