Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TC1301B-APAVUATR are identified based on the following critical parameters that define functional equivalence:

Primary Substitution Criteria:

• Output configuration: Positive fixed voltage regulation
• Number of regulators: Dual-output architecture
• Output voltage levels: 1.8V and 3.3V compatibility (core voltage standards)
• Mounting type: Surface mount technology
• Package form factor: 8-MSOP or compatible 8-pin MSOP variants
• Operating temperature range: -40°C to 125°C
• Protection features: Over-current and over-temperature protection
• Compliance: RoHS3 compliant, REACH unaffected

The MIC5357-SGYMME qualifies as a substitute based on matching dual-output positive fixed regulation architecture, compatible output voltage levels (1.8V, 3.3V), identical operating temperature range, surface mount 8-MSOP packaging, and equivalent protection features. Differences in maximum input voltage (5.5V vs. 6V), output current ratings, and dropout voltage specifications represent trade-offs that may be acceptable depending on application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the TC1301B-APAVUATR and MIC5357-SGYMME maintain active product status with full RoHS3 compliance and REACH unaffected certification, ensuring regulatory compliance for current and future applications. Selection between these components should be based on specific application requirements regarding output current capacity and maximum input voltage tolerance.

The TC1301B-APAVUATR is suitable for applications requiring the 2.63V output option and lower dropout voltage performance at 300mA output current. The MIC5357-SGYMME provides higher output current capability (500mA per channel) and is appropriate for applications with higher power delivery requirements, though it does not support the 2.63V output level and operates with a maximum input voltage of 5.5V rather than 6V.

Both devices share identical operating temperature ranges, quiescent current characteristics, and dual-output architecture, making them functionally interchangeable for applications utilizing only the 1.8V and 3.3V output levels within the specified input voltage and current constraints.

Frequently Asked Questions (FAQ)

Q: Can the MIC5357-SGYMME directly replace the TC1301B-APAVUATR in all applications?

A: Direct replacement is possible only for applications utilizing the 1.8V and 3.3V output levels and operating within the MIC5357-SGYMME's maximum input voltage of 5.5V. Applications requiring the 2.63V output or input voltages approaching 6V require the TC1301B-APAVUATR.

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

A: The MIC5357-SGYMME offers higher output current capacity (500mA per channel versus 300mA and 150mA) but exhibits higher dropout voltage (0.3V versus 0.18V at maximum current). The TC1301B-APAVUATR supports an additional 2.63V output level and accepts input voltages up to 6V compared to 5.5V for the MIC5357-SGYMME.

Q: Are the packages physically compatible?

A: Both devices use 8-MSOP surface mount packaging with identical 0.118" (3.00mm) width. The MIC5357-SGYMME includes an exposed pad variant, which may provide improved thermal performance in applications requiring enhanced heat dissipation.

Q: Do both parts meet the same compliance standards?

A: Yes, both the TC1301B-APAVUATR and MIC5357-SGYMME are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the moisture sensitivity level difference?

A: The TC1301B-APAVUATR has MSL 1 (unlimited shelf life), while the MIC5357-SGYMME has MSL 3 (168 hours). This affects storage and handling requirements, with the TC1301B-APAVUATR offering more flexible inventory management.
