AP2401ASN-7 Equivalent & Substitute Parts

Part Overview

The AP2401ASN-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, slew rate control, and comprehensive fault protection including current limiting, over-temperature, reverse current, and UVLO monitoring. The device is actively produced and widely deployed in power management circuits requiring controlled load switching with status feedback capabilities.

Substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain disruptions, or specific packaging preferences while maintaining functional equivalence within the defined electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP2401ASN-7 are qualified based on strict electrical and mechanical parameter matching:

Critical Matching Parameters:

• Switch Type: USB Switch
• Output Configuration: High Side, P-Channel, 1:1 ratio
• Current Rating: 2A maximum output
• Load Voltage Range: 2.7V ~ 5.5V
• On-Resistance: 70mOhm typical
• Package: 6-UDFN Exposed Pad (U-DFN2020-6)
• Mounting: Surface Mount
• Temperature Range: -40°C ~ 85°C
• Fault Protection: Current Limiting (Fixed), Over Temperature, Reverse Current, UVLO
• Features: Load Discharge, Slew Rate Controlled, Status Flag

The AP2511ASN-7 meets all critical electrical parameters and mechanical specifications. The primary functional difference is the input logic type (Non-Inverting vs. Inverting), which must be evaluated against circuit design requirements. Both parts maintain identical load voltage ratings, current capacity, thermal performance, and protection features.

Parameter Comparison

Engineering Selection Recommendations

Both AP2401ASN-7 and AP2511ASN-7 are active products from Diodes Incorporated with identical ROHS3 compliance and REACH unaffected status. Selection between these parts depends on circuit-level input logic requirements:

AP2401ASN-7 is specified for designs requiring inverting input logic, where a high input signal produces a low output state (switch off).

AP2511ASN-7 is specified for designs requiring non-inverting input logic, where a high input signal produces a high output state (switch on).

Both parts deliver equivalent electrical performance across all load voltage, current, thermal, and protection specifications. Packaging, mounting, and thermal characteristics are identical. Selection should be based on the control signal polarity required by the host microcontroller or logic circuit.

Frequently Asked Questions (FAQ)

Q: Can AP2511ASN-7 directly replace AP2401ASN-7 without circuit modification?

A: Direct replacement requires verification of input logic polarity. The AP2511ASN-7 uses non-inverting logic while AP2401ASN-7 uses inverting logic. If the control signal polarity matches the design requirement, replacement is functionally equivalent. If not, the control signal must be inverted in firmware or hardware.

Q: Are the electrical performance characteristics identical between these parts?

A: Yes. Both parts deliver 2A maximum output current, 70mOhm typical on-resistance, 2.7V to 5.5V load voltage operation, and identical fault protection features including current limiting, over-temperature, reverse current, and UVLO monitoring.

Q: Do both parts use the same package and mounting process?

A: Yes. Both AP2401ASN-7 and AP2511ASN-7 use the 6-UDFN Exposed Pad package (U-DFN2020-6) with surface mount assembly. PCB footprints are identical.

Q: What is the primary difference between these two parts?

A: The input logic type. AP2401ASN-7 features inverting input logic, while AP2511ASN-7 features non-inverting input logic. All other electrical, thermal, and mechanical specifications are equivalent.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both AP2401ASN-7 and AP2511ASN-7 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.
