AO7600 Equivalent & Substitute Parts

Part Overview

The AO7600 is an N and P-Channel MOSFET array manufactured by Alpha & Omega Semiconductor Inc., designed for surface mount applications in the SC-70-6 package. This device features a 20V drain-to-source voltage rating with continuous drain currents of 900mA and 600mA, and a maximum power dissipation of 300mW. The AO7600 is classified as obsolete, making identification of equivalent substitute parts essential for ongoing design support and production continuity. Substitute parts must maintain electrical compatibility across voltage ratings, current handling, thermal characteristics, and package form factors while meeting modern compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AO7600 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Drain to Source Voltage (Vdss): Must equal or exceed 20V
• Configuration: Must be N and P-Channel
• FET Feature: Must be Logic Level Gate
• Operating Temperature Range: Must span -55°C to 150°C
• Mounting Type: Must be Surface Mount
• Package compatibility: Must support 6-TSSOP, SC-88, or SOT-363 form factors

Performance Parameters for Substitution:

• Continuous Drain Current (Id): Substitute must meet or exceed 900mA for N-channel and 600mA for P-channel at 25°C
• Rds On (Max): Substitute must not exceed 300mOhm at the specified Id and Vgs conditions
• Power Dissipation (Max): Substitute must support minimum 300mW

All three substitute parts listed below satisfy these criteria and are classified as active products with current manufacturing status.

Engineering Selection Recommendations

DMG1016UDW-7 (Diodes Incorporated)

The DMG1016UDW-7 is an active product with enhanced electrical performance relative to the AO7600. It provides higher continuous drain currents (1.07A N-channel, 845mA P-channel) and increased power dissipation capability (330mW). This part is ROHS3 compliant and maintains full compatibility with the AO7600 across voltage, temperature, and package specifications. The DMG1016UDW-7 is suitable for applications requiring performance headroom beyond the original AO7600 specifications.

FDG6332C (onsemi)

The FDG6332C is an active product from the PowerTrench® series that maintains electrical parity with the AO7600 across critical parameters. It delivers 700mA N-channel and 600mA P-channel continuous drain current with identical 300mOhm Rds On specification at comparable operating points. The FDG6332C is supplied in SC-88 (SC-70-6) package format, providing direct mechanical compatibility. This part is ROHS3 compliant and represents a direct functional equivalent for applications where the original AO7600 specifications are sufficient.

PMGD290UCEAX (Nexperia USA Inc.)

The PMGD290UCEAX is an active product qualified to AEC-Q100 automotive standards, making it suitable for automotive and high-reliability applications. It provides 725mA N-channel and 500mA P-channel continuous drain current with 380mOhm Rds On at 500mA. The PMGD290UCEAX is supplied in 6-TSSOP package format and is ROHS3 compliant. This part is appropriate for applications requiring automotive-grade qualification and reliability assurance.

Frequently Asked Questions (FAQ)

Q: Can the DMG1016UDW-7 be used as a direct replacement for the AO7600?

A: Yes. The DMG1016UDW-7 meets all critical electrical parameters (20V Vdss, N and P-Channel configuration, Logic Level Gate, -55°C to 150°C operating range) and is compatible with the same package families (6-TSSOP, SC-88, SOT-363). The higher current ratings and power dissipation provide additional performance margin. Verify PCB layout compatibility with the SOT-363 supplier package format.

Q: What is the difference between the FDG6332C and PMGD290UCEAX?

A: Both parts are active substitutes for the AO7600. The FDG6332C is a general-purpose part with 700mA N-channel current and SC-88 package compatibility. The PMGD290UCEAX is automotive-qualified (AEC-Q100) with 725mA N-channel current and 6-TSSOP package format. Select the PMGD290UCEAX for automotive applications requiring qualification documentation; select the FDG6332C for general industrial applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All three substitute parts (DMG1016UDW-7, FDG6332C, PMGD290UCEAX) are ROHS3 compliant. The original AO7600 does not specify RoHS status. All parts maintain REACH Unaffected status and MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which substitute part has the lowest Rds On specification?

A: The AO7600 and FDG6332C both specify 300mOhm Rds On at their respective operating points. The DMG1016UDW-7 specifies 450mOhm at 600mA, and the PMGD290UCEAX specifies 380mOhm at 500mA. For applications requiring minimum on-resistance, the AO7600 or FDG6332C are preferred; however, the FDG6332C is the only active product with this specification.

Q: What package considerations apply when substituting the AO7600?

A: The AO7600 is supplied in SC-70-6 package format. All substitute parts support 6-TSSOP, SC-88, and SOT-363 package families. The DMG1016UDW-7 is supplied as SOT-363; the FDG6332C is supplied as SC-88 (SC-70-6); the PMGD290UCEAX is supplied as 6-TSSOP. Verify that the selected supplier package format is compatible with your PCB footprint and assembly process.

Q: Can the PMGD290UCEAX be used in non-automotive applications?

A: Yes. The PMGD290UCEAX meets all electrical and thermal requirements for general-purpose applications. Automotive qualification (AEC-Q100) is an additional assurance of reliability and does not restrict use in non-automotive designs. This part is suitable for any application within its electrical specifications.

Q: What is the inventory status of these substitute parts?

A: DMG1016UDW-7 has 35,400 pieces in stock; FDG6332C has 20,669 pieces in stock; PMGD290UCEAX has 1,180 pieces in stock. All parts are classified as active products with current manufacturing support.
