AP2181DMPG-13 Equivalent & Substitute Parts

Part Overview

The AP2181DMPG-13 is an active Power Management IC (PMIC) manufactured by Diodes Incorporated, classified as a Power Switch/Driver with P-Channel output configuration. This component operates as a 1:1 USB Switch with high-side output control, designed for load switching applications in the 2.7V to 5.5V operating range. The part is in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across the specified parameter set.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AP2181DMPG-13 is determined by strict equivalence across the following critical parameters:

• Electrical Performance: Output type (P-Channel), output configuration (High Side), maximum output current (1.5A), on-resistance (95mOhm typical), and load voltage range (2.7V ~ 5.5V)
• Functional Architecture: Switch type (USB Switch), 1:1 input-to-output ratio, single output configuration, and interface type (On/Off control)
• Protection & Features: Fault protection mechanisms (Current Limiting Fixed, Over Temperature, Reverse Current, UVLO), load discharge capability, and status flag output
• Physical & Environmental: 8-MSOP-EP package with exposed pad, surface mount configuration, operating temperature range (-40°C ~ 85°C), and MSL 1 rating
• Regulatory Compliance: RoHS3 compliance, REACH unaffected status, and ECCN EAR99 classification

The primary differentiator among identified substitutes is the input control logic type (Inverting vs. Non-Inverting), which affects circuit integration requirements but does not alter electrical load-switching performance.

Parameter Comparison

Engineering Selection Recommendations

Both AP2181DMPG-13 and AP2191DMPG-13 maintain active product status with full RoHS3 compliance and identical electrical specifications for load switching applications. Selection between these parts is determined by input control logic requirements:

• AP2181DMPG-13: Select when inverting input logic is required in the circuit design. Higher inventory availability (17900 units) supports production volume requirements.
• AP2191DMPG-13: Select when non-inverting input logic is required in the circuit design. Lower inventory availability (1248 units) may impact lead time for high-volume applications.

Both parts are certified for identical operating temperature ranges, fault protection mechanisms, and regulatory compliance frameworks. Physical footprint and thermal characteristics remain equivalent across the 8-MSOP-EP package specification.

Frequently Asked Questions (FAQ)

Q: Can AP2191DMPG-13 directly replace AP2181DMPG-13 without circuit modification?

A: Direct replacement requires circuit design review. The primary difference is input control logic: AP2181DMPG-13 uses inverting input, while AP2191DMPG-13 uses non-inverting input. Circuit integration logic must be verified to ensure proper gate drive signal compatibility.

Q: Are the electrical load-switching specifications identical between these parts?

A: Yes. Both parts deliver identical maximum output current (1.5A), on-resistance (95mOhm typical), load voltage range (2.7V ~ 5.5V), and fault protection features (Current Limiting Fixed, Over Temperature, Reverse Current, UVLO).

Q: Do both parts use the same physical package?

A: Yes. Both AP2181DMPG-13 and AP2191DMPG-13 use the 8-MSOP-EP package with exposed pad, 0.118" width, 3.00mm body dimension. PCB footprint and thermal pad layout are identical.

Q: What is the significance of the input type difference?

A: Input type (Inverting vs. Non-Inverting) determines the logic level required to activate the power switch. Inverting logic activates the switch with a low input signal; non-inverting logic activates with a high input signal. Selection depends on the control signal source in the application circuit.

Q: Are both parts RoHS3 compliant?

A: Yes. Both AP2181DMPG-13 and AP2191DMPG-13 carry RoHS3 compliance certification with MSL 1 (unlimited moisture sensitivity rating).

Q: What is the inventory status for each part?

A: AP2181DMPG-13 has 17900 units in stock. AP2191DMPG-13 has 1248 units in stock. Inventory levels may affect lead time for high-volume production orders.
