AP2171AS-13 Equivalent & Substitute Parts

Part Overview

The AP2171AS-13 is an active power switch IC manufactured by Diodes Incorporated, classified as a Power Management (PMIC) component. This device functions as a P-Channel power switch with 1:1 input-output ratio, designed for USB switching applications. The part is currently in active production status with 3,900 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in applications where packaging or inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP2171AS-13 are identified based on strict electrical and mechanical parameter equivalence. The critical parameters determining substitutability are:

• Switch Type: USB Switch
• Output Type: P-Channel
• Number of Outputs: 1
• Ratio - Input:Output: 1:1
• Output Configuration: High Side
• Voltage - Load: 2.7V ~ 5.5V
• Current - Output (Max): 1A
• Rds On (Typ): 95mOhm
• Fault Protection: Current Limiting (Fixed), Over Temperature, Reverse Current, UVLO
• Operating Temperature: -40°C ~ 85°C (TA)
• Mounting Type: Surface Mount
• Package / Case: 8-SOIC (0.154", 3.90mm Width)

The AP2171AS-13 has three identified substitutes within the Diodes Incorporated product line: AP2161SG-13, AP2171DSG-13, and AP2171SG-13. These parts maintain identical electrical performance specifications and package dimensions. Variations exist only in packaging format (Tape & Reel versus Cut Tape) and input signal logic (Non-Inverting versus Inverting for AP2161SG-13).

Parameter Comparison

Engineering Selection Recommendations

All four parts—AP2171AS-13, AP2161SG-13, AP2171DSG-13, and AP2171SG-13—maintain active product status and ROHS3 compliance. Selection between these parts depends on specific application requirements:

AP2171AS-13 and AP2171DSG-13 are functionally identical, both featuring Non-Inverting input logic and Tape & Reel packaging. These are preferred when input signal polarity matches the application design and automated assembly processes require continuous reel format.

AP2171SG-13 provides equivalent electrical performance with Non-Inverting input logic but differs in Moisture Sensitivity Level (MSL 3 versus MSL 1) and packaging format (Cut Tape & Digi-Reel). This part is suitable for applications with standard moisture exposure profiles and manual or semi-automated assembly.

AP2161SG-13 differs in input signal logic (Inverting) and packaging format (Cut Tape). This part is selected only when the application circuit requires Inverting input control logic. Direct substitution without circuit modification is not applicable for this variant.

All parts are REACH Unaffected and classified under ECCN EAR99, meeting standard export compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can AP2161SG-13 be used as a direct replacement for AP2171AS-13?

A: AP2161SG-13 has Inverting input logic while AP2171AS-13 has Non-Inverting input logic. Direct substitution without circuit modification is not applicable. The input signal polarity must match the application design.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging is continuous format suitable for automated pick-and-place assembly. Cut Tape is individual tape segments suitable for manual or semi-automated assembly. Both formats contain identical components; packaging selection depends on assembly process requirements.

Q: Does Moisture Sensitivity Level (MSL) affect component substitutability?

A: MSL rating indicates moisture exposure tolerance during storage and assembly. AP2171SG-13 has MSL 3 (168 hours maximum exposure) while other variants have MSL 1 (unlimited exposure). Selection depends on storage conditions and assembly process duration. Higher MSL ratings require stricter moisture control.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. AP2171AS-13, AP2161SG-13, AP2171DSG-13, and AP2171SG-13 are all ROHS3 compliant and REACH Unaffected.

Q: What electrical parameters must remain constant for substitution?

A: Critical parameters for substitution are: P-Channel output type, 1:1 input-output ratio, High Side output configuration, 2.7V–5.5V load voltage range, 1A maximum output current, 95mOhm typical on-resistance, and identical fault protection features (Current Limiting, Over Temperature, Reverse Current, UVLO).

Q: Can AP2171DSG-13 replace AP2171AS-13 in existing designs?

A: Yes. AP2171DSG-13 is electrically and mechanically identical to AP2171AS-13, with identical input logic (Non-Inverting), package dimensions, and electrical specifications. Both use Tape & Reel packaging. Substitution is direct.
