TPS2014D Equivalent & Substitute Parts

Part Overview

The TPS2014D is a Power Management IC (PMIC) manufactured by Texas Instruments, functioning as a USB Switch with N-Channel output configuration. This device operates as a 1:1 power switch/driver rated for 600mA maximum output current in an 8-SOIC surface mount package. The TPS2014D is classified as "Not For New Designs," indicating it has reached end-of-life status. Identifying equivalent and substitute parts is necessary for ongoing system support, legacy product maintenance, and design continuity where this component is currently deployed.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TPS2014D is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Switch Type: USB Switch
• Output Configuration: High Side
• Number of Outputs: 1
• Ratio - Input:Output: 1:1
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Performance Criteria:

• Current - Output (Max): Must equal or exceed 600mA
• Rds On (Typ): 95mOhm (matching specification)
• Fault Protection: Must include Current Limiting (Fixed) and Over Temperature protection

Electrical Operating Range:

• Voltage - Load: Must support 4.75V ~ 5.25V range or broader compatible range
• Operating Temperature: Must support 0°C ~ 125°C or equivalent industrial range

The substitute parts listed below meet these criteria with variations in output channel type (N-Channel vs. P-Channel), current ratings, and input logic configuration. These variations are acceptable within the USB Switch category where functional equivalence is maintained through the specified electrical and mechanical parameters.

Engineering Selection Recommendations

TPS2041BD (Texas Instruments, N-Channel) This substitute maintains the same manufacturer and N-Channel output type as the TPS2014D. It is classified as Active product status, ensuring continued availability and support. The TPS2041BD operates across a broader voltage range (2.7V ~ 5.5V) and includes UVLO (Under-Voltage Lock-Out) protection in addition to the current limiting and over-temperature features of the original. The maximum output current is rated at 500mA, which is lower than the TPS2014D's 600mA specification. The Rds On value of 70mOhm is superior to the original 95mOhm. This option is suitable for applications where N-Channel topology is required and output current does not exceed 500mA.

AP2161SG-13 (Diodes Incorporated, P-Channel, 1A) This substitute provides the highest current rating at 1A, exceeding the TPS2014D's 600mA specification. It maintains the same 95mOhm Rds On value and includes comprehensive fault protection (Current Limiting, Over Temperature, Reverse Current, UVLO). The P-Channel output configuration requires circuit topology adjustment compared to the N-Channel original. This option is suitable for applications requiring higher current capacity within the same package footprint.

AP2181SG-13 (Diodes Incorporated, P-Channel, 1.5A) This substitute offers the highest current rating at 1.5A with the same 95mOhm Rds On specification. It includes all protection features (Current Limiting, Over Temperature, Reverse Current, UVLO) and operates across 2.7V ~ 5.5V. The P-Channel configuration requires circuit topology adjustment. This option is suitable for applications requiring maximum current capacity and enhanced protection features.

AP2141SG-13 (Diodes Incorporated, P-Channel, 500mA) This substitute provides 500mA output current with 95mOhm Rds On and includes Load Discharge feature in addition to standard protections. The P-Channel output configuration requires circuit topology adjustment. This option is suitable for lower-current applications where the additional Load Discharge feature provides design benefit.

All substitute parts are ROHS3 compliant and available in Active product status, ensuring long-term supply chain viability compared to the TPS2014D's "Not For New Designs" classification.

Frequently Asked Questions (FAQ)

Q: Can I directly replace TPS2014D with TPS2041BD without circuit modifications? A: Yes. Both devices are N-Channel high-side switches in 8-SOIC packages with identical pin configurations. The TPS2041BD operates across a broader voltage range and includes UVLO protection. However, the maximum output current is 500mA versus the TPS2014D's 600mA, so applications drawing more than 500mA require evaluation.

Q: What is the difference between N-Channel and P-Channel substitutes? A: N-Channel devices (TPS2014D, TPS2041BD) and P-Channel devices (AP2141SG-13, AP2161SG-13, AP2181SG-13) have different circuit topologies and gate drive requirements. P-Channel substitutes require inverted control logic and different gate drive circuitry. Direct pin-for-pin replacement is not possible without circuit redesign.

Q: Why do the Diodes Incorporated parts have lower operating temperature ranges? A: The Diodes parts specify -40°C ~ 85°C (TA, ambient temperature) while the TPS2014D specifies 0°C ~ 125°C (TJ, junction temperature). These are different measurement references. For applications requiring junction temperatures above 85°C, the TPS2041BD or TPS2014D should be evaluated based on actual thermal conditions.

Q: Which substitute has the best electrical performance? A: The TPS2041BD offers the lowest Rds On at 70mOhm (versus 95mOhm for all others), resulting in lower power dissipation. The AP2181SG-13 offers the highest current capacity at 1.5A. Selection depends on whether minimizing power loss or maximizing current capacity is the priority.

Q: Are all substitutes available in the same package? A: Yes. All substitute parts are available in 8-SOIC (0.154", 3.90mm Width) surface mount packages, matching the TPS2014D footprint. Packaging formats (Tube, Tape & Reel, Cut Tape) vary by supplier but do not affect PCB compatibility.

Q: What is the significance of "Product Status: Active" for the substitutes? A: Active status indicates the part is in current production and supported by the manufacturer. The TPS2014D's "Not For New Designs" status means it is obsolete or being phased out. Substitutes with Active status provide assurance of continued availability and technical support.

Q: Do all substitutes include the same fault protection features? A: No. The TPS2014D includes Current Limiting (Fixed) and Over Temperature protection. The Diodes substitutes add Reverse Current and UVLO protection. The TPS2041BD adds UVLO. Enhanced protection features in substitutes provide additional design margin and reliability.
