TPS2014P Equivalent & Substitute Parts

Part Overview

The TPS2014P is a power switch/driver IC manufactured by Texas Instruments, designed for USB switching applications with 1:1 input-to-output ratio and high-side N-channel output configuration. This device delivers 600mA maximum output current in an 8-PDIP package and includes integrated current limiting and over-temperature protection.

The TPS2014P carries a "Not For New Designs" product status, indicating Texas Instruments has discontinued active development for this component. Organizations requiring equivalent functionality for new or ongoing applications must evaluate qualified substitute parts that maintain electrical and mechanical compatibility within the specified parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS2014P is determined by strict alignment across the following critical parameters:

Mandatory Compatibility Criteria:

• Switch Type: USB Switch
• Number of Outputs: 1
• Ratio - Input:Output: 1:1
• Output Configuration: High Side
• Output Type: N-Channel
• Interface: On/Off
• Package / Case: 8-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole

Electrical Performance Parameters:

• Voltage - Load range must encompass or exceed 4.75V ~ 5.25V
• Current - Output (Max) must meet or exceed 600mA
• Rds On (Typ) should not significantly degrade thermal performance
• Fault Protection must include at minimum Current Limiting and Over Temperature protection

Compliance Requirements:

• RoHS3 Compliant status required
• REACH Unaffected status required

The MIC2545A-1YN from Microchip Technology satisfies all mandatory criteria and demonstrates enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MIC2545A-1YN qualifies as a direct functional substitute for the TPS2014P based on matching package geometry, electrical interface topology, and compliance certifications. Both components are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component procurement.

The MIC2545A-1YN carries Active product status, ensuring continued manufacturer support, availability, and technical documentation. The TPS2014P's "Not For New Designs" classification makes the MIC2545A-1YN the appropriate selection for new product development and long-term supply chain stability.

Electrical performance of the MIC2545A-1YN exceeds TPS2014P specifications across current capacity (3A vs. 600mA) and on-resistance (35mΩ vs. 95mΩ), resulting in reduced thermal dissipation and improved efficiency in USB switching applications. Enhanced fault protection features, including adjustable current limiting and reverse current protection, provide additional circuit robustness.

Operating temperature ranges differ between the two devices. Design validation is required if applications demand sustained operation at temperatures below 0°C or above 85°C ambient.

Frequently Asked Questions (FAQ)

Q: Can the MIC2545A-1YN directly replace the TPS2014P without PCB modifications?

A: Yes. Both components use identical 8-DIP package geometry (0.300", 7.62mm pitch) and pin-compatible through-hole mounting. No PCB layout changes are required for mechanical substitution. Electrical interface compatibility is maintained through matching 1:1 input-to-output topology and On/Off control interface.

Q: What are the key electrical differences between these parts?

A: The MIC2545A-1YN provides higher output current capacity (3A vs. 600mA), lower on-resistance (35mΩ vs. 95mΩ), and wider load voltage range (2.7V ~ 5.5V vs. 4.75V ~ 5.25V). Fault protection is enhanced with adjustable current limiting and reverse current blocking. These differences represent performance improvements suitable for USB switching applications.

Q: Are there operating temperature considerations for substitution?

A: The TPS2014P operates from 0°C to 125°C (junction temperature), while the MIC2545A-1YN operates from -40°C to 85°C (ambient temperature). Applications requiring sustained operation below 0°C or above 85°C ambient must be evaluated against the MIC2545A-1YN's specified temperature range. Temperature measurement methodology differs between the two specifications (junction vs. ambient).

Q: Do both parts meet current regulatory compliance requirements?

A: Yes. Both the TPS2014P and MIC2545A-1YN are ROHS3 Compliant and REACH Unaffected, meeting current electronic component procurement standards for regulated markets.

Q: Why is the TPS2014P marked "Not For New Designs"?

A: This classification indicates Texas Instruments has concluded active development and support for this product line. Existing inventory remains available, but new designs should utilize actively supported alternatives such as the MIC2545A-1YN to ensure long-term supply chain continuity and access to current technical documentation.

Q: What is the significance of the MIC2545A-1YN's "Active" product status?

A: Active status confirms Microchip Technology continues manufacturing, supporting, and developing this component. Active products receive ongoing technical updates, maintain stable supply chains, and provide access to current application notes and design resources.
