• Frequency - Transition: 10GHz minimum
• Noise Figure: 1.2dB or lower @ 1GHz
• Gain: 17dB or higher
• Power - Max: 450mW or higher
• DC Current Gain (hFE): 60 minimum @ 50mA, 5V
• Current - Collector (Max): 100mA or higher
• Operating Temperature: 150°C (TJ) or higher

Mechanical Parameters:

• Mounting Type: Surface Mount
• Package / Case: SOT-343F
• Supplier Device Package: 4-MCPH

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The MCH4015-TL-H qualifies as a direct substitute based on identical electrical specifications and mechanical packaging, with the distinction of active product status and Tape & Reel packaging availability.

Parameter Comparison

Engineering Selection Recommendations

The MCH4015-TL-H is the primary substitute for the obsolete MCH4017-TL-H. Both components are manufactured by onsemi and share identical electrical and mechanical specifications across all critical RF transistor parameters. The MCH4015-TL-H maintains active product status, ensuring long-term availability and supply chain reliability.

Both parts comply with ROHS3 and REACH requirements, with MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling. The MCH4015-TL-H is available in Tape & Reel packaging, which is standard for production environments, whereas the MCH4017-TL-H was supplied in bulk packaging.
