Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS54060DRCR is determined by the following core electrical and mechanical parameters:

• Functional Category: Step-down buck regulator with adjustable positive output
• Output Current Rating: 500mA minimum
• Input Voltage Range: Minimum 4.6V to 60V maximum
• Output Voltage Range: Adjustable from 0.8V minimum
• Switching Frequency: 100kHz to 2.5MHz operation
• Number of Outputs: Single output configuration
• Mounting: Surface mount technology
• Synchronous Rectifier: Non-synchronous topology

The RT6360GSP qualifies as a functional equivalent based on matching these core parameters. Differences in package type (8-SOIC vs. 10-VFDFN), maximum operating temperature (125°C vs. 150°C), and MSL rating represent design trade-offs that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the TPS54060DRCR and RT6360GSP are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

TPS54060DRCR Selection Criteria:

• Applications requiring maximum operating temperature to 150°C
• Designs utilizing 10-VFDFN package footprint
• Unlimited moisture sensitivity level (MSL 1) for extended storage or humid environments
• Split rail topology requirement

RT6360GSP Selection Criteria:

• Applications with maximum operating temperature requirement of 125°C or lower
• PCB designs accommodating 8-SOIC package footprint
• Standard moisture sensitivity handling (MSL 3, 168 hours)
• Minimum input voltage of 4V acceptable for the application

The 0.5V difference in minimum input voltage (4.6V vs. 4V) and 25°C difference in maximum operating temperature represent the primary electrical distinctions. Package geometry differences require PCB layout modification between these alternatives.

Frequently Asked Questions (FAQ)

Q: Can RT6360GSP replace TPS54060DRCR in all applications?

A: Functional replacement is possible when application requirements do not exceed the RT6360GSP specifications. The 4V minimum input voltage and 125°C maximum operating temperature must be verified against system requirements. PCB layout modification is required due to package differences.

Q: What is the impact of the different package types?

A: The TPS54060DRCR uses 10-VFDFN (3x3mm) while RT6360GSP uses 8-SOIC (0.154" width). These packages have different footprints, pin counts, and thermal characteristics. PCB redesign is necessary for substitution.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. The primary compliance difference is MSL rating: TPS54060DRCR is MSL 1 (unlimited storage), while RT6360GSP is MSL 3 (168-hour limit). This affects component handling and storage procedures.

Q: What is the significance of the 0.5V input voltage difference?

A: The TPS54060DRCR operates from 4.6V minimum input, while RT6360GSP requires 4V minimum. Applications with input sources below 4V cannot use the RT6360GSP as a substitute.

Q: How do the output voltage ranges compare?

A: Both parts support 0.8V minimum adjustable output. The TPS54060DRCR reaches 58V maximum output, while RT6360GSP reaches 60V. For applications requiring output above 58V, the RT6360GSP provides additional headroom.

Q: What thermal considerations apply to these substitutes?

A: The TPS54060DRCR supports continuous operation to 150°C junction temperature, while RT6360GSP is rated to 125°C. High-temperature applications must use the TPS54060DRCR. The 10-VFDFN package of the TPS54060DRCR provides different thermal performance than the 8-SOIC package of the RT6360GSP.
