AO4407AL P-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The AO4407AL is a P-Channel Metal Oxide Semiconductor Field Effect Transistor (MOSFET) manufactured by Alpha & Omega Semiconductor Inc., rated for 30V drain-to-source voltage with 12A continuous drain current. The device is housed in an 8-SOIC surface mount package and is designed for applications requiring moderate power dissipation in compact form factors.

The AO4407AL carries an Obsolete product status, indicating it is no longer in active production. This status necessitates identification of equivalent substitute components that maintain identical or compatible electrical and mechanical specifications for continued system support and new design alternatives.

Substitute Part Grouping Explanation

Substitution of the AO4407AL is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• FET Type: P-Channel topology
• Drain to Source Voltage (Vdss): 30V minimum rating
• Continuous Drain Current (Id): 12A minimum at 25°C
• On-Resistance (Rds On): 11mOhm maximum at specified conditions
• Gate Threshold Voltage (Vgs(th)): 3V maximum at 250µA
• Gate Charge (Qg): 39nC maximum at 10V
• Maximum Gate Voltage (Vgs): ±25V minimum rating
• Input Capacitance (Ciss): 2600pF maximum at 15V
• Power Dissipation: 3.1W maximum
• Operating Temperature Range: -55°C to 150°C minimum

Mechanical Equivalence Criteria:

• Mounting Type: Surface Mount
• Package Type: 8-SOIC with 0.154" (3.90mm) width specification
• Moisture Sensitivity Level: MSL 1 or better

The AO4407A is identified as a parametric equivalent manufactured by the same supplier. Additional cross-reference substitutes listed (AOSP21307, STS10P3LLH6, DMG4407SSS-13, FDS6679AZ, PJL9415_R2_00001) represent alternative manufacturers' devices that meet the same electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: AO4407A

The AO4407A is the direct parametric equivalent from Alpha & Omega Semiconductor Inc. All electrical specifications, mechanical dimensions, and environmental ratings are identical to the AO4407AL. The AO4407A is available in Cut Tape (CT) and Digi-Reel® packaging formats with 150,400 pieces in current inventory. Both devices maintain REACH Unaffected status and EAR99 export classification.

The AO4407A carries a "Not For New Designs" product status, indicating limited future availability. For applications requiring long-term component sourcing stability, evaluation of alternative manufacturer equivalents (AOSP21307, STS10P3LLH6, DMG4407SSS-13, FDS6679AZ, PJL9415_R2_00001) is appropriate, provided these devices meet the specified electrical and mechanical parameters.

Compliance Considerations:

Both the AO4407AL and AO4407A maintain MSL 1 (Unlimited) moisture sensitivity classification, permitting unrestricted storage and handling without desiccant requirements. Both devices are REACH Unaffected and classified under ECCN EAR99, with HTSUS code 8541.29.0095.

The AO4407A includes RoHS3 Compliance certification, whereas the AO4407AL does not specify RoHS status. For applications subject to RoHS directives, the AO4407A is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the AO4407A directly replace the AO4407AL in existing designs?

A: Yes. The AO4407A is a parametric equivalent with identical electrical specifications (30V Vdss, 12A Id, 11mOhm Rds On, 39nC Qg) and mechanical package (8-SOIC, 0.154" width). Both devices operate across -55°C to 150°C and maintain MSL 1 classification. Pin-to-pin compatibility is confirmed.

Q: What is the difference between the AO4407AL and AO4407A product statuses?

A: The AO4407AL is classified as Obsolete, indicating end-of-life status with no further production. The AO4407A is classified as Not For New Designs, indicating limited availability and restricted recommendation for new applications. For legacy system support, the AO4407A provides continued sourcing; for new designs, alternative manufacturer equivalents should be evaluated.

Q: Are there packaging differences between AO4407AL and AO4407A?

A: The AO4407AL packaging format is not specified in available documentation. The AO4407A is supplied in Cut Tape (CT) and Digi-Reel® formats. Both devices use the 8-SOIC package with 0.154" (3.90mm) width. Confirm packaging requirements with your procurement specification before ordering.

Q: What electrical parameters must be matched for substitution?

A: Critical parameters for substitution are: P-Channel FET type, 30V minimum Vdss, 12A minimum Id at 25°C, 11mOhm maximum Rds On at 12A/20V, 3V maximum Vgs(th) at 250µA, 39nC maximum Qg at 10V, ±25V Vgs rating, 2600pF maximum Ciss at 15V, and 3.1W maximum power dissipation. All substitute devices must meet or exceed these specifications.

Q: Is the 8-SOIC package pinout identical across all equivalent devices?

A: The 8-SOIC package format is standardized with 0.154" (3.90mm) width. Pin assignments for P-Channel MOSFETs in 8-SOIC configuration follow industry conventions. Verify pinout diagrams in device datasheets to confirm gate, drain, and source terminal assignments before PCB layout or rework operations.

Q: What is the significance of MSL 1 (Unlimited) classification?

A: MSL 1 (Unlimited) indicates the device has no moisture sensitivity restrictions. Components may be stored and handled without desiccant packaging or time-limited exposure windows. This classification simplifies inventory management and reduces handling constraints compared to higher MSL ratings.

Q: Are the AO4407AL and AO4407A suitable for new product designs?

A: The AO4407AL (Obsolete) is not suitable for new designs. The AO4407A (Not For New Designs) carries restricted recommendation for new applications due to limited future availability. For new product development, evaluate alternative manufacturer equivalents that meet the specified 30V/12A/11mOhm electrical parameters and confirm long-term supply commitments with component distributors.
