Key Parameters

Substitute Part Grouping Explanation

Substitution of the MCH4014-TL-H is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Transistor Type: NPN
• Voltage - Collector Emitter Breakdown (Max): 12V
• Frequency - Transition: 10GHz
• Package / Case: SOT-343F (4-MCPH)
• Mounting Type: Surface Mount

Allowable Parameter Variations: Substitute parts may exceed the maximum ratings of the MCH4014-TL-H in the following parameters without compromising circuit compatibility:

• Power - Max: 350mW or greater
• Current - Collector (Max): 30mA or greater
• Gain: Equal to or greater than 18dB
• DC Current Gain (hFE): Equal to or greater than 60

The MCH4015-TL-H qualifies as a direct substitute based on these criteria. It maintains identical voltage, frequency, and package specifications while providing enhanced current handling (100mA vs. 30mA) and increased power dissipation capability (450mW vs. 350mW).

Engineering Selection Recommendations

MCH4015-TL-H as Primary Substitute:

The MCH4015-TL-H is the direct substitute for the obsolete MCH4014-TL-H. Both devices are manufactured by onsemi and share identical electrical performance at the specified operating point (12V breakdown voltage, 10GHz transition frequency, 1.2dB noise figure at 1GHz). The MCH4015-TL-H maintains full compatibility with the SOT-343F package footprint and surface mount assembly process.

The MCH4015-TL-H provides superior performance margins through increased maximum collector current (100mA vs. 30mA) and power dissipation (450mW vs. 350mW). These enhancements do not introduce incompatibility; they extend the operational envelope of the circuit.

Compliance Status:

Both the MCH4014-TL-H and MCH4015-TL-H are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level) classification. The MCH4015-TL-H is currently in active production status, ensuring long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the MCH4015-TL-H directly replace the MCH4014-TL-H in existing designs?

A: Yes. The MCH4015-TL-H is electrically and mechanically compatible with the MCH4014-TL-H. Both devices feature identical voltage ratings (12V), frequency response (10GHz), noise characteristics (1.2dB @ 1GHz), and package geometry (SOT-343F). No circuit modifications are required.

Q: What are the key differences between these two parts?

A: The MCH4015-TL-H provides higher current handling capability (100mA maximum vs. 30mA) and greater power dissipation capacity (450mW vs. 350mW). The gain specification is 17dB for the MCH4015-TL-H compared to 18dB for the MCH4014-TL-H. These differences represent performance enhancements that do not compromise compatibility.

Q: Why is the MCH4014-TL-H listed as obsolete?

A: The MCH4014-TL-H has been discontinued by onsemi. The MCH4015-TL-H serves as the active replacement in the product line, offering equivalent or superior performance characteristics.

Q: Are there packaging differences between these parts?

A: Both parts use the SOT-343F package (4-MCPH) for surface mount assembly. The MCH4014-TL-H is supplied in Cut Tape (CT) and Digi-Reel® packaging, while the MCH4015-TL-H is supplied in Tape & Reel (TR) format. The physical component dimensions and PCB footprint are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the MCH4014-TL-H and MCH4015-TL-H are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (unlimited moisture sensitivity). Both carry the same ECCN (EAR99) classification.

Q: What is the noise figure specification, and is it identical between these parts?

A: Both parts specify a typical noise figure of 1.2dB at 1GHz. This parameter is identical across both devices.

Q: Can the MCH4015-TL-H be used in high-frequency RF applications?

A: Yes. The MCH4015-TL-H is rated for 10GHz transition frequency and is suitable for RF applications requiring this frequency range. The electrical characteristics remain consistent with the MCH4014-TL-H for RF performance.
