AO7410 N-Channel MOSFET 30V 1.7A SC70-3 Equivalent & Substitute Parts

Part Overview

The AO7410 is an N-Channel metal oxide semiconductor field-effect transistor (MOSFET) rated for 30V drain-to-source voltage with a continuous drain current of 1.7A at 25°C. This device is packaged in the SC-70-3 (SOT-323) surface mount configuration and dissipates a maximum of 350mW. The AO7410 carries a product status designation of "Not For New Designs," indicating that while the part remains available in inventory, it is no longer recommended for new circuit development. Identifying equivalent and substitute parts is necessary to support existing designs, facilitate production continuity, and enable migration to active product alternatives where applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AO7410 is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Drain-to-Source Voltage (Vdss) must equal or exceed 30V
• Continuous Drain Current (Id) must equal or exceed 1.7A at 25°C
• Gate Threshold Voltage (Vgs(th)) must be compatible with 1.5V @ 250µA specification
• Maximum Gate Voltage (Vgs) must support ±12V operation
• Operating Temperature Range must encompass -55°C to 150°C (TJ)

Mechanical Compatibility Criteria:

• Package must be SC-70 or SOT-323 (surface mount, three-pin configuration)
• Mounting type must be surface mount
• Pin configuration must be compatible with SC-70-3 footprint

Compliance Criteria:

• RoHS3 compliance required
• MSL rating of 1 (Unlimited) required
• REACH Unaffected status required

Substitute parts are grouped into two categories: direct equivalents (matching all electrical parameters within tolerance) and functional alternatives (exceeding minimum electrical requirements while maintaining mechanical and compliance compatibility).

Parameter Comparison

Engineering Selection Recommendations

AO7400 (Alpha & Omega Semiconductor Inc.)

The AO7400 is a direct electrical equivalent to the AO7410, sharing identical voltage and current ratings of 30V and 1.7A respectively. Both devices are rated for 350mW power dissipation and operate across the -55°C to 150°C temperature range. The AO7400 differs in packaging format (Cut Tape and Digi-Reel versus Tape & Reel) and exhibits slightly higher on-state resistance (85 mOhm versus 55 mOhm). The AO7400 carries the same "Not For New Designs" product status as the AO7410. Both parts maintain ROHS3 compliance, MSL 1 rating, and REACH Unaffected status. The AO7400 is suitable for direct substitution in existing designs where packaging format compatibility is confirmed.

AOSN32338C (Alpha & Omega Semiconductor Inc.)

The AOSN32338C is a functional alternative rated for higher continuous drain current (3.7A versus 1.7A) while maintaining the same 30V voltage rating. This device provides increased power dissipation capability (1.1W versus 350mW) and lower on-state resistance (51 mOhm versus 55 mOhm). The AOSN32338C carries an "Active" product status, indicating it is recommended for new designs. All electrical parameters remain compatible with the AO7410 gate threshold voltage, maximum gate voltage, and operating temperature specifications. This part is suitable for applications requiring higher current capacity or improved thermal performance within the same package footprint.

DMN3067LW-13 and DMN3067LW-7 (Diodes Incorporated)

The DMN3067LW-13 and DMN3067LW-7 are functionally equivalent alternatives manufactured by Diodes Incorporated, both rated for 30V and 2.6A continuous drain current. These devices provide 500mW power dissipation, exceeding the AO7410 specification. Both variants maintain compatibility with the ±12V gate voltage range and -55°C to 150°C operating temperature. The primary difference between these two parts is packaging format: DMN3067LW-13 is supplied in Tape & Reel, while DMN3067LW-7 is supplied in Cut Tape and Digi-Reel. Both parts carry "Active" product status and maintain ROHS3 compliance, MSL 1 rating, and REACH Unaffected status. These parts are suitable for substitution where cross-manufacturer qualification is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the AO7400 be used as a direct replacement for the AO7410?

A: The AO7400 is electrically compatible with the AO7410, sharing identical 30V voltage rating and 1.7A current rating. Both devices operate across -55°C to 150°C and dissipate 350mW maximum. The primary difference is packaging format (Cut Tape & Digi-Reel versus Tape & Reel). Substitution is valid provided the packaging format is compatible with your procurement and assembly processes.

Q: What is the advantage of using AOSN32338C over AO7410?

A: The AOSN32338C provides higher continuous drain current (3.7A versus 1.7A) and greater power dissipation capability (1.1W versus 350mW) within the same SC-70-3 package footprint. The AOSN32338C also carries "Active" product status, making it suitable for new designs. Applications requiring higher current handling or improved thermal performance benefit from this upgrade.

Q: Are the Diodes Incorporated DMN3067LW series parts compatible with the AO7410?

A: Yes, both DMN3067LW-13 and DMN3067LW-7 are compatible with the AO7410. These parts maintain the 30V voltage rating, support ±12V gate voltage, and operate across the -55°C to 150°C temperature range. The 2.6A continuous drain current and 500mW power dissipation exceed AO7410 specifications. Both variants carry "Active" product status. The difference between the two is packaging format only.

Q: What is the difference between DMN3067LW-13 and DMN3067LW-7?

A: DMN3067LW-13 and DMN3067LW-7 are electrically identical N-Channel MOSFETs with 30V rating and 2.6A continuous drain current. The sole difference is packaging format: DMN3067LW-13 is supplied in Tape & Reel, while DMN3067LW-7 is supplied in Cut Tape and Digi-Reel. Selection between these variants depends on your procurement and assembly requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all substitute parts listed (AO7400, AOSN32338C, DMN3067LW-13, and DMN3067LW-7) are ROHS3 compliant with MSL 1 (Unlimited) rating and REACH Unaffected status, matching the AO7410 compliance profile.

Q: Can I use a substitute part with higher current rating in place of the AO7410?

A: Yes, substitute parts with higher current ratings (AOSN32338C at 3.7A or DMN3067LW series at 2.6A) are functionally compatible with the AO7410 (1.7A). Higher current-rated devices operate within the same voltage and temperature specifications and maintain the same package footprint. Circuit design must account for any changes in on-state resistance characteristics.

Q: What should I verify before substituting parts?

A: Verify the following before substitution: (1) Packaging format compatibility with your PCB footprint and assembly process; (2) On-state resistance (Rds On) compatibility with your circuit's switching and thermal requirements; (3) Gate charge (Qg) compatibility with your gate drive circuit; (4) Availability and lead time for the substitute part; (5) Any design-specific requirements regarding product status (Active versus Not For New Designs).
