TPS2014DRG4 Equivalent & Substitute Parts

Part Overview

The TPS2014DRG4 is a Power Management IC (PMIC) manufactured by Texas Instruments, functioning as a USB Switch with N-Channel output configuration. This device is classified as a Power Switch/Driver with 1:1 ratio, rated for 600mA maximum output current at 4.75V to 5.25V load voltage. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TPS2014DRG4 is determined by the following critical parameters:

• Switch Type & Function: USB Switch with 1:1 ratio, High Side output configuration
• Output Current Rating: Minimum 600mA to meet or exceed original specification
• Load Voltage Range: Compatible with 4.75V ~ 5.25V operation
• Package Compatibility: 8-SOIC form factor for direct PCB replacement
• Fault Protection: Current Limiting and Over Temperature protection required
• Product Status: Active availability for production continuity

The substitute parts listed (AP2141SG-13, AP2161SG-13, AP2181SG-13) are manufactured by Diodes Incorporated and meet these substitution criteria. All substitutes feature P-Channel output configuration with inverting or non-inverting input types, expanded load voltage ranges (2.7V ~ 5.5V), enhanced fault protection including Reverse Current and UVLO, and higher current ratings (500mA to 1.5A). These devices maintain the 8-SOIC package footprint and 95mOhm typical Rds On specification.

Parameter Comparison

Engineering Selection Recommendations

AP2141SG-13 is suitable for applications requiring 500mA output current with extended load voltage range (2.7V ~ 5.5V). This part includes Load Discharge feature and non-inverting input type. Product status is Active with full availability.

AP2161SG-13 accommodates 1A output current with inverting input configuration. This device provides higher current capacity than the original TPS2014DRG4 while maintaining the same package footprint and Rds On specification. Product status is Active with 31,500 units in stock.

AP2181SG-13 delivers 1.5A maximum output current, the highest rating among substitutes, with inverting input type. This part offers maximum design margin for current-limited applications. Product status is Active with 16,961 units in stock.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and 8-SOIC package compatibility. Selection between substitutes depends on required output current capacity and input signal polarity requirements for the specific application circuit.

Frequently Asked Questions (FAQ)

Q: Can AP2141SG-13, AP2161SG-13, or AP2181SG-13 directly replace TPS2014DRG4 on existing PCBs?

A: Yes, all substitute parts share the 8-SOIC package footprint (0.154", 3.90mm Width), enabling direct PCB replacement. However, the output channel type differs (N-Channel vs. P-Channel), requiring circuit design verification to confirm signal polarity compatibility.

Q: What is the primary difference between the three substitute options?

A: The three Diodes Incorporated parts differ in maximum output current rating: AP2141SG-13 (500mA), AP2161SG-13 (1A), and AP2181SG-13 (1.5A). All maintain identical Rds On (95mOhm) and package specifications. Input type varies between non-inverting (AP2141SG-13) and inverting (AP2161SG-13, AP2181SG-13).

Q: Are the substitute parts compliant with the same regulatory standards as TPS2014DRG4?

A: Yes, all substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original part's compliance profile.

Q: What additional fault protection features do the substitutes provide?

A: The Diodes Incorporated substitutes include Reverse Current and UVLO (Under Voltage Lock Out) protection in addition to Current Limiting and Over Temperature protection found in the original TPS2014DRG4.

Q: How does the expanded load voltage range (2.7V ~ 5.5V) of substitutes affect compatibility?

A: The substitute parts operate across a wider voltage range than the original specification (4.75V ~ 5.25V). This expanded range provides greater design flexibility and compatibility with diverse power supply configurations while remaining fully compatible with the original 4.75V ~ 5.25V operating window.

Q: What is the impact of operating temperature range differences?

A: The original TPS2014DRG4 operates at 0°C ~ 125°C (junction temperature), while substitutes operate at -40°C ~ 85°C (ambient temperature). Applications requiring operation above 85°C ambient or 125°C junction temperature require thermal analysis to confirm substitute suitability.
