AP2171SG-13 Equivalent & Substitute Parts
Part Overview
The AP2171SG-13 is an active P-Channel power switch/driver manufactured by Diodes Incorporated, designed for USB switching applications with 1:1 input-output ratio and high-side output configuration. This component operates across a 2.7V to 5.5V load voltage range with 1A maximum output current and includes integrated status flag and comprehensive fault protection (current limiting, over-temperature, reverse current, and UVLO). The part is ROHS3 compliant and currently in active production status with 12,900 units in stock.
Equivalent and substitute parts are identified based on matching electrical specifications (output type, current rating, voltage range, on-resistance), mechanical compatibility (8-SOIC package), and functional features (status flag, fault protection mechanisms). Substitutes may vary in input logic type, packaging format, or manufacturer while maintaining core electrical performance parameters.

Substitute Part Grouping Explanation
Substitution eligibility for the AP2171SG-13 is determined by the following critical parameters:
Primary Matching Criteria:
- Output Type (P-Channel vs. N-Channel architecture)
- Current Rating (1A nominal capacity)
- Load Voltage Range (2.7V ~ 5.5V compatibility)
- On-Resistance (Rds On specification)
- Package Type (8-SOIC form factor)
- Fault Protection Features (current limiting, over-temperature, reverse current, UVLO)
- Status Flag Functionality
Secondary Variation Parameters (Allowable Differences):
- Input Logic Type (Non-Inverting vs. Inverting)
- Packaging Format (Cut Tape vs. Tape & Reel)
- Manufacturer (Diodes Incorporated vs. Texas Instruments)
- Operating Temperature Range (within functional limits)
- Moisture Sensitivity Level (MSL rating)
Substitutes are grouped into three categories: parametric equivalents from Diodes Incorporated (same base electrical specifications, packaging variations), and manufacturer-recommended alternatives from Texas Instruments (different output channel type with comparable current handling and voltage specifications).

Engineering Selection Recommendations
Diodes Incorporated Parametric Equivalents (AP2171 Series):
AP2171AS-13 and AP2171DSG-13 are direct parametric equivalents to AP2171SG-13, maintaining identical electrical specifications (P-Channel, 1A output, 95mOhm Rds On, 2.7V-5.5V load voltage). The primary difference is packaging format: AP2171AS-13 and AP2171DSG-13 are supplied in Tape & Reel format versus Cut Tape for the base AP2171SG-13. All three parts are ROHS3 compliant and active production status. MSL rating differs (AP2171SG-13: MSL 3; AP2171AS-13 and AP2171DSG-13: MSL 1), indicating improved moisture handling in the latter variants.
AP2161SG-13 is a parametric equivalent with identical electrical performance but features Inverting input logic versus the Non-Inverting input of AP2171SG-13. This represents a functional difference requiring circuit-level evaluation. AP2161SG-13 offers superior MSL rating (MSL 1 vs. MSL 3) and higher inventory availability (31,500 units).
Texas Instruments Manufacturer-Recommended Alternatives (TPS203x Series):
TPS2030D/TPS2030DR, TPS2031D/TPS2031DR, TPS2032D/TPS2032DR, and TPS2033D represent N-Channel alternatives with comparable voltage and current specifications. These parts differ fundamentally in output channel type (N-Channel vs. P-Channel), which requires different circuit topology. Current ratings range from 200mA (TPS2030) to 1.5A (TPS2033), with TPS2032D/TPS2032DR matching the 1A specification of AP2171SG-13. All TPS203x variants feature lower on-resistance (33mOhm vs. 95mOhm), extended operating temperature range (-40°C to 125°C vs. -40°C to 85°C), and MSL 1 rating. Fault protection includes current limiting, over-temperature, and UVLO, but excludes reverse current protection present in AP2171SG-13.
All substitute parts maintain 8-SOIC package compatibility, ROHS3 compliance, and active production status.
Frequently Asked Questions (FAQ)
Q: Can AP2161SG-13 directly replace AP2171SG-13 in existing designs?
A: AP2161SG-13 is electrically equivalent but features Inverting input logic compared to the Non-Inverting input of AP2171SG-13. Direct substitution requires circuit-level evaluation to confirm input signal polarity compatibility. Both parts maintain identical load voltage range (2.7V-5.5V), output current (1A), on-resistance (95mOhm), and fault protection features.
Q: What is the primary difference between AP2171SG-13 and AP2171AS-13?
A: Both parts are parametric equivalents with identical electrical specifications (P-Channel, 1A, 95mOhm, 2.7V-5.5V). The difference is packaging format: AP2171SG-13 is supplied in Cut Tape (CT) & Digi-Reel format, while AP2171AS-13 is supplied in Tape & Reel (TR) format. AP2171AS-13 also features improved MSL rating (MSL 1 vs. MSL 3).
Q: Can Texas Instruments TPS203x series parts replace the AP2171SG-13?
A: TPS203x parts are manufacturer-recommended alternatives but represent a different architecture (N-Channel vs. P-Channel output). Substitution requires circuit redesign to accommodate the different output topology. TPS2032D/TPS2032DR match the 1A current rating. All TPS203x variants offer lower on-resistance (33mOhm) and extended temperature range (-40°C to 125°C) but lack reverse current protection.
Q: What does the MSL rating difference between AP2171SG-13 (MSL 3) and AP2171AS-13 (MSL 1) mean?
A: MSL (Moisture Sensitivity Level) indicates moisture absorption limits. AP2171SG-13 (MSL 3) allows 168 hours of exposure before baking is required. AP2171AS-13 (MSL 1) has unlimited moisture exposure tolerance. For applications with extended storage or high-humidity environments, MSL 1 rated parts provide greater handling flexibility.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. AP2171SG-13 and all listed substitute parts (AP2161SG-13, AP2171AS-13, AP2171DSG-13, and all TPS203x variants) are ROHS3 compliant and REACH unaffected.
Q: What is the significance of the 95mOhm vs. 33mOhm on-resistance difference?
A: On-resistance (Rds On) directly affects power dissipation and thermal performance. AP2171SG-13 and Diodes equivalents feature 95mOhm typical on-resistance, while TPS203x alternatives feature 33mOhm. Lower on-resistance reduces heat generation at equivalent current levels, improving efficiency. Selection depends on thermal budget and application current requirements.
Q: Do all substitute parts include reverse current protection?
A: No. AP2171SG-13 and Diodes Incorporated equivalents (AP2161SG-13, AP2171AS-13, AP2171DSG-13) include reverse current protection in their fault protection suite. Texas Instruments TPS203x series parts include current limiting, over-temperature, and UVLO protection but do not include reverse current protection.
