AO7417 P-Channel MOSFET 20V 1.9A SC70-6 Equivalent & Substitute Parts

Part Overview

The AO7417 is an active P-Channel Metal Oxide Semiconductor Field Effect Transistor (MOSFET) manufactured by Alpha & Omega Semiconductor Inc. This surface mount device operates at 20V drain-to-source voltage with a continuous drain current rating of 1.9A at 25°C and dissipates up to 570mW. The component is packaged in SC-70-6 (6-TSSOP/SOT-363) configuration and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical performance parameters are met within the same package family, enabling direct replacement in circuit designs while maintaining functional specifications and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AO7417 are identified based on strict electrical and mechanical compatibility criteria. The substitution logic is based on the following key parameters:

Electrical Compatibility Criteria:

• FET Type: P-Channel (required match)
• Drain to Source Voltage (Vdss): 20V (required match)
• Package Family: SC-70-6 / SC-88 / 6-TSSOP / SOT-363 (pin-compatible packages)
• Operating Temperature Range: -55°C to 150°C (required match)
• Gate Voltage Rating (Vgs Max): ±8V (required match)
• RoHS3 Compliance: Required
• Moisture Sensitivity Level: MSL 1 (required match)

Performance Parameters (Allowable Variation):

• Continuous Drain Current (Id): Equal to or greater than 1.9A
• On-Resistance (Rds On): Equal to or less than specified value
• Gate Charge (Qg): Comparable within application tolerance
• Power Dissipation: Equal to or greater than 570mW
• Input Capacitance (Ciss): Comparable within application tolerance

The FDG332PZ from onsemi meets all electrical and mechanical substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

AO7417 Selection Criteria: The AO7417 is suitable for applications requiring a P-Channel MOSFET with 20V rating and 1.9A continuous drain current in a compact SC-70-6 surface mount package. The component is active, RoHS3 compliant, and carries unlimited moisture sensitivity level (MSL 1), indicating no special storage or handling requirements. This part is recommended for new designs and existing applications where the specified electrical parameters are sufficient.

FDG332PZ Selection Criteria: The FDG332PZ is a manufacturer-recommended substitute offering enhanced electrical performance characteristics. It provides higher continuous drain current (2.6A versus 1.9A), increased power dissipation capability (750mW versus 570mW), and lower input capacitance (560pF versus 745pF). The FDG332PZ is pin-compatible within the SC-70-6/SC-88 package family, active in production status, RoHS3 compliant, and carries MSL 1 rating. This part is suitable for applications requiring higher current capacity or improved thermal performance while maintaining voltage and temperature specifications.

Compliance and Regulatory Status: Both parts are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.21.0095. Both components operate across the identical temperature range (-55°C to 150°C) and share equivalent gate voltage ratings (±8V maximum).

Frequently Asked Questions (FAQ)

Q: Can the FDG332PZ directly replace the AO7417 in existing circuit designs?

A: Yes. The FDG332PZ is pin-compatible within the SC-70-6/SC-88 package family and meets all electrical compatibility requirements. Both parts are P-Channel MOSFETs with 20V Vdss rating, ±8V gate voltage rating, and identical operating temperature range (-55°C to 150°C). The FDG332PZ provides equal or superior electrical performance across all critical parameters.

Q: What are the key differences between the AO7417 and FDG332PZ?

A: The primary differences are: (1) Continuous drain current: FDG332PZ provides 2.6A versus AO7417's 1.9A; (2) Power dissipation: FDG332PZ rated at 750mW versus AO7417's 570mW; (3) Input capacitance: FDG332PZ has 560pF versus AO7417's 745pF; (4) Gate threshold voltage: FDG332PZ specified at 1.5V versus AO7417's 1V; (5) On-resistance: FDG332PZ rated at 95mOhm versus AO7417's 80mOhm. All other electrical and mechanical parameters are equivalent.

Q: Are there package compatibility concerns when substituting these parts?

A: No. Both the AO7417 and FDG332PZ utilize pin-compatible package designations within the SC-70-6/SC-88/6-TSSOP/SOT-363 family. Physical footprints and pin assignments are compatible for direct PCB substitution.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the AO7417 and FDG332PZ are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity level. Both are classified under ECCN EAR99 and HTSUS code 8541.21.0095.

Q: Which part should be selected for new designs?

A: Selection depends on application current requirements. For applications requiring 1.9A or less continuous drain current with standard thermal performance, the AO7417 is appropriate. For applications requiring higher current capacity (up to 2.6A) or improved thermal performance, the FDG332PZ is recommended. Both parts are active in production status and suitable for new designs.

Q: What is the significance of the gate charge (Qg) difference between these parts?

A: Gate charge affects switching speed and gate drive requirements. The FDG332PZ has slightly lower gate charge (10.8nC versus 11nC), resulting in marginally faster switching characteristics. This difference is negligible for most applications and does not affect substitution compatibility.

Q: Are there any temperature or voltage derating considerations?

A: Both parts operate across the identical temperature range (-55°C to 150°C junction temperature) and share the same maximum gate voltage rating (±8V). No additional derating considerations apply when substituting between these parts.
