Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS22903YFPR is determined by the following critical parameters:

• Switch Type & Output Configuration: General Purpose, High Side topology
• Ratio Configuration: 1:1 input-to-output ratio
• Package Compatibility: 4-DSBGA form factor
• Operating Temperature Range: -40°C ~ 85°C
• Interface Type: On/Off control with Non-Inverting input
• Compliance Standards: ROHS3 Compliant, REACH Unaffected

The TPS22914BYFPR qualifies as a substitute based on matching package type (4-DSBGA), identical operating temperature range, equivalent interface characteristics, and identical compliance certifications. Both devices share the same base product family architecture from Texas Instruments and maintain compatibility with the specified electrical and mechanical requirements for high-side power switching applications.

Parameter Comparison

Engineering Selection Recommendations

The TPS22903YFPR is classified as Obsolete, making the TPS22914BYFPR the designated substitute from Texas Instruments. The substitute part maintains Active product status, ensuring long-term availability and continued manufacturer support.

Both devices are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution. The identical operating temperature range (-40°C ~ 85°C) and matching 4-DSBGA package ensure thermal and mechanical compatibility with existing PCB designs.

The TPS22914BYFPR provides enhanced electrical performance characteristics: increased maximum output current (2A versus 500mA) and reduced on-resistance (37mOhm versus 66mOhm). The substitute supports an expanded load voltage range (1.05V ~ 5.5V versus 1.1V ~ 3.6V), offering greater application flexibility.

The primary design consideration is the channel type difference: the original TPS22903YFPR uses P-Channel topology while the TPS22914BYFPR employs N-Channel topology. Circuit topology modifications may be required to accommodate this channel type change in high-side switching configurations.

Frequently Asked Questions (FAQ)

Q: Can the TPS22914BYFPR directly replace the TPS22903YFPR without circuit modifications?

A: Both devices share identical package geometry (4-DSBGA), operating temperature range, and interface characteristics. However, the channel type differs: TPS22903YFPR is P-Channel while TPS22914BYFPR is N-Channel. High-side switching applications using P-Channel and N-Channel topologies require different circuit configurations. Circuit redesign is necessary to accommodate the channel type change.

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

A: The TPS22914BYFPR provides superior electrical performance: maximum output current increases from 500mA to 2A, on-resistance decreases from 66mOhm to 37mOhm, and load voltage range expands from 1.1V–3.6V to 1.05V–5.5V. These improvements enable the substitute to support higher power applications.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the TPS22903YFPR and TPS22914BYFPR are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: Why is the TPS22903YFPR classified as Obsolete?

A: The TPS22903YFPR has reached end-of-life status. The TPS22914BYFPR, with Active product status, represents the current generation equivalent from Texas Instruments and is recommended for new designs and ongoing production support.

Q: Are the moisture sensitivity levels identical?

A: Yes. Both devices have Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.
