Key Parameters

Substitute Part Grouping Explanation

Substitution of the MCH6604-TL-E is determined by the following electrical and mechanical parameters:

Critical Substitution Criteria:

• Configuration: Dual N-channel MOSFET array
• FET Feature: Logic level gate operation
• Drain-to-source voltage rating: Minimum 50V (equal or higher acceptable)
• Continuous drain current: Minimum 250mA (equal or higher acceptable)
• Maximum power dissipation: Minimum 800mW (equal or higher acceptable)
• Mounting type: Surface mount
• Operating temperature range: Maximum junction temperature of 150°C or higher
• Moisture sensitivity: MSL 1 or equivalent

Substitute Parts Identified:

1. 2N7002DW (onsemi) — Active product status; 60V Vdss, 115mA Id, 200mW power rating
2. DMN61D8LVT-13 (Diodes Incorporated) — Active product status; 60V Vdss, 630mA Id, 820mW power rating

Both substitute parts meet the voltage and configuration requirements. The DMN61D8LVT-13 provides superior current handling and power dissipation capability. The 2N7002DW operates within the specified voltage envelope but with reduced current capacity.

Parameter Comparison

Engineering Selection Recommendations

2N7002DW Selection Criteria: The 2N7002DW is an active product from onsemi with ROHS3 compliance and REACH unaffected status. It maintains the same manufacturer ecosystem as the MCH6604-TL-E. However, the 115mA continuous drain current rating is below the original 250mA specification. This substitute is suitable for applications where the actual operating current does not exceed 115mA and where the 200mW power dissipation limit is acceptable. The SC-88 package requires PCB layout modification from the original 6-MCPH footprint.

DMN61D8LVT-13 Selection Criteria: The DMN61D8LVT-13 is an active product from Diodes Incorporated with ROHS3 compliance and REACH unaffected status. This substitute exceeds the original specifications in both continuous drain current (630mA) and maximum power dissipation (820mW), providing design margin and enhanced performance capability. The TSOT-26 package requires PCB layout modification from the original 6-MCPH footprint. This substitute is recommended for applications requiring current handling at or above the original 250mA specification.

Both substitutes operate within the maximum junction temperature of 150°C and maintain MSL 1 moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can the 2N7002DW directly replace the MCH6604-TL-E without circuit modification?

A: The 2N7002DW is electrically compatible in terms of voltage rating and logic level gate operation. However, the 115mA continuous drain current rating is lower than the original 250mA specification. Circuit modification is required if the application demands current above 115mA. Additionally, the SC-88 package footprint differs from the 6-MCPH package, requiring PCB layout changes.

Q: Is the DMN61D8LVT-13 a pin-compatible replacement?

A: The DMN61D8LVT-13 is not pin-compatible with the MCH6604-TL-E. The TSOT-26 package differs from the 6-MCPH package. PCB layout redesign is necessary for implementation. However, the electrical characteristics are compatible, and the superior current and power ratings provide design flexibility.

Q: What are the package differences between these parts?

A: The MCH6604-TL-E uses a 6-MCPH package (6-SMD, flat leads). The 2N7002DW uses SC-88 (SC-70-6) packaging. The DMN61D8LVT-13 uses TSOT-26 (SOT-23-6 thin) packaging. Each package has different pin configurations and footprints, requiring PCB redesign for substitution.

Q: Are all three parts RoHS compliant?

A: The MCH6604-TL-E does not specify RoHS status in the provided data. The 2N7002DW and DMN61D8LVT-13 are both ROHS3 compliant. All three parts are REACH unaffected and classified as EAR99 for export control purposes.

Q: Which substitute is recommended for high-current applications?

A: The DMN61D8LVT-13 is recommended for applications requiring continuous drain current at or above 250mA. It provides 630mA continuous current capability and 820mW power dissipation, exceeding the original MCH6604-TL-E specifications.

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

A: All three parts—MCH6604-TL-E, 2N7002DW, and DMN61D8LVT-13—are classified as MSL 1 (Unlimited), indicating unlimited shelf life without moisture control requirements.

Q: Can these substitutes operate at the same temperature range as the original part?

A: The MCH6604-TL-E specifies a maximum junction temperature of 150°C. Both substitutes operate from -55°C to 150°C, providing equivalent or extended temperature range capability.
