AP2401SN-7 Equivalent & Substitute Parts

Part Overview

The AP2401SN-7 is an active P-Channel power switch/driver manufactured by Diodes Incorporated, designed for USB switching applications. This component operates as a 1:1 high-side switch with integrated load discharge, status flag output, and comprehensive fault protection including current limiting, over-temperature shutdown, reverse current blocking, and under-voltage lockout (UVLO). The part is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified based on matching electrical performance parameters, mechanical compatibility, and functional feature sets. The parts listed maintain identical load voltage ranges, output current ratings, on-resistance characteristics, and fault protection mechanisms, enabling direct substitution in applications where the specific input logic type permits.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AP2401SN-7 is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Load voltage range: 2.7V ~ 5.5V
• Maximum output current: 2A
• On-resistance: 70mOhm typical
• Output configuration: High-side P-Channel
• Fault protection suite: Current limiting, over-temperature, reverse current blocking, UVLO

Mechanical Compatibility:

• Package type: 6-UDFN Exposed Pad
• Mounting: Surface Mount
• Supplier device package: U-DFN2020-6

Functional Features:

• Load discharge capability
• Status flag output
• 1:1 input-to-output ratio

Input Logic Consideration: The AP2401SN-7 features inverting input logic. Parts AP2301SN-7, AP2311SN-7, and AP2411SN-7 feature non-inverting input logic. These differences require circuit-level evaluation to determine substitutability based on the control signal requirements of the application.

All substitute parts maintain identical electrical performance, thermal characteristics, compliance certifications, and package specifications as the main part.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status with full RoHS3 compliance, REACH unaffected classification, and identical MSL 1 (unlimited) moisture sensitivity ratings. All parts are manufactured by Diodes Incorporated and share identical electrical specifications, thermal operating ranges, and fault protection architectures.

Selection between AP2401SN-7 and its substitutes depends on input logic requirements. The AP2401SN-7 operates with inverting input logic, while AP2301SN-7, AP2311SN-7, and AP2411SN-7 operate with non-inverting input logic. Direct substitution is permissible only when the application circuit accommodates the specific input logic type of the selected part.

Inventory availability varies across the substitute parts, with AP2411SN-7 offering the highest stock level at 15,200 pieces, followed by AP2401SN-7 at 12,100 pieces.

Frequently Asked Questions (FAQ)

Q: Can AP2301SN-7, AP2311SN-7, or AP2411SN-7 be used as direct replacements for AP2401SN-7?

A: These parts are electrically and mechanically equivalent with one critical difference: input logic type. AP2401SN-7 uses inverting logic, while the other three use non-inverting logic. Direct substitution is possible only if the application circuit can accommodate the different input logic configuration.

Q: What is the difference between inverting and non-inverting input logic?

A: Inverting input logic (AP2401SN-7) activates the switch when the input signal is low. Non-inverting input logic (AP2301SN-7, AP2311SN-7, AP2411SN-7) activates the switch when the input signal is high. The choice depends on the control signal polarity in your circuit design.

Q: Are all substitute parts in the same package?

A: Yes. All parts use the 6-UDFN Exposed Pad package with identical mechanical dimensions and pin configurations, enabling direct PCB footprint compatibility.

Q: Do all parts have the same fault protection features?

A: Yes. All parts include current limiting (fixed), over-temperature shutdown, reverse current blocking, and under-voltage lockout (UVLO). Load discharge and status flag outputs are present on all variants.

Q: What is the operating temperature range for these parts?

A: All parts operate from -40°C to 85°C (ambient temperature), making them suitable for industrial and commercial applications.

Q: Are there compliance or certification differences between the parts?

A: No. All parts maintain identical RoHS3 compliance, REACH unaffected status, MSL 1 rating, and EAR99 export classification.
