MCH3383-TL-H Equivalent & Substitute Parts

Part Overview

The MCH3383-TL-H is a P-Channel MOSFET manufactured by onsemi, rated for 12V drain-to-source voltage with 3.5A continuous drain current at 25°C. This device is packaged in a surface mount SC-70FL/MCPH3 configuration and is designed for applications requiring compact P-channel switching and amplification in low-voltage circuits.

The MCH3383-TL-H carries an obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for legacy systems or redesign initiatives.

Substitute Part Grouping Explanation

Substitute parts for the MCH3383-TL-H are identified based on strict electrical and mechanical compatibility criteria. The following parameters define the substitution scope:

Electrical Compatibility Criteria:

• FET Type: P-Channel topology required
• Drain to Source Voltage (Vdss): Minimum 12V rating
• Continuous Drain Current (Id): Minimum 3.5A at 25°C
• On-State Resistance (Rds On): Performance within acceptable operating margins
• Gate Threshold Voltage (Vgs(th)): Compatible gate drive requirements
• Operating Temperature Range: Support for -55°C to 150°C or equivalent

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount configuration
• Package Style: 3-SMD flat lead packages
• Pin Configuration: Compatible with SC-70FL/MCPH3 or equivalent 3-pin surface mount footprints

Compliance Criteria:

• RoHS3 Compliance: Required for environmental and regulatory alignment
• Moisture Sensitivity Level: MSL 1 or equivalent
• REACH Status: Unaffected or compliant

The RAF040P01TCL from Rohm Semiconductor meets these substitution criteria through equivalent electrical ratings, compatible surface mount packaging, and matching compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

MCH3383-TL-H (onsemi): This part carries obsolete product status. Existing inventory of 2821 pieces is available. The device is ROHS3 compliant and carries MSL 1 rating. Selection of this part is appropriate only for applications where existing stock must be consumed or where legacy system maintenance requires exact part matching.

RAF040P01TCL (Rohm Semiconductor): This part maintains active product status with 17,400 pieces in current inventory. The RAF040P01TCL is ROHS3 compliant with MSL 1 rating, ensuring long-term supply chain availability and regulatory compliance. The substitute offers improved electrical performance characteristics, including lower on-state resistance (30 mOhm vs. 69 mOhm) and higher continuous drain current rating (4A vs. 3.5A). Both devices support equivalent operating temperature ranges and surface mount packaging configurations.

For new designs or production transitions, the RAF040P01TCL is the preferred selection due to active product status and enhanced performance margins. For legacy system support, the MCH3383-TL-H remains available through existing inventory channels.

Frequently Asked Questions (FAQ)

Q: Can the RAF040P01TCL directly replace the MCH3383-TL-H in existing PCB designs?

A: Both devices use 3-SMD surface mount packaging with flat leads. Physical footprint compatibility exists between SC-70FL/MCPH3 and TUMT3 packages. Electrical parameters are compatible within the specified operating ranges. PCB layout verification is necessary to confirm pin-to-pin alignment and thermal management adequacy.

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

A: The RAF040P01TCL provides higher continuous drain current (4A vs. 3.5A) and lower on-state resistance (30 mOhm vs. 69 mOhm). The MCH3383-TL-H features lower gate charge (6.2 nC vs. 37 nC) and lower input capacitance (1010 pF vs. 4000 pF). Gate threshold voltage differs slightly (800 mV vs. 1000 mV). Maximum gate voltage rating differs (-5V to +5V vs. -8V maximum). These differences affect switching speed, power dissipation, and gate drive requirements.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the MCH3383-TL-H and RAF040P01TCL are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the product status difference, and why does it matter?

A: The MCH3383-TL-H is obsolete, while the RAF040P01TCL is active. Obsolete status indicates the manufacturer has discontinued production. Active status ensures ongoing availability, technical support, and supply chain continuity. For new designs or long-term production, active parts are preferred.

Q: Can I use the RAF040P01TCL in applications originally designed for the MCH3383-TL-H?

A: Functional compatibility exists for P-channel switching applications at 12V with current requirements up to 3.5A. The RAF040P01TCL's higher current rating (4A) and lower on-state resistance provide performance margin. Gate drive circuit compatibility must be verified, as the RAF040P01TCL has higher gate charge and input capacitance, potentially requiring adjusted gate drive timing.

Q: What packaging formats are available for the RAF040P01TCL?

A: The RAF040P01TCL is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, supporting both manual and automated assembly processes.
