Substitute Part Grouping Explanation

Substitute parts for the TC2014-2.8VCTTR are classified into two categories based on substitution logic:

MFR Recommended Substitutes — Parts that exceed or match all critical electrical parameters while maintaining compatibility with the original application requirements:

MIC5255-2.8YD5-TR and MIC5255-2.8YM5-TR: Higher output current capacity (150mA) with improved PSRR and additional Under Voltage Lockout protection
MIC5323-2.8YD5-TR: Highest output current capacity (300mA) with superior PSRR performance

Parametric Equivalent — Parts that maintain identical electrical specifications and package compatibility:

TC1014-2.8VCT713: Same 50mA output current and 2.8V fixed output with marginally improved dropout voltage

Substitution eligibility is determined by the following key parameters:

Fixed output voltage of 2.8V
Output current rating equal to or greater than 50mA
Maximum input voltage of 5.5V or higher
SOT-23-5 package family compatibility
Operating temperature range of -40°C to 125°C minimum
Enable control feature presence
Over Current and Over Temperature protection

Engineering Selection Recommendations

All substitute parts listed maintain active product status and full RoHS3 compliance, ensuring regulatory alignment with the original TC2014-2.8VCTTR specification.

For direct pin-compatible replacement with identical electrical performance: Select TC1014-2.8VCT713. This parametric equivalent maintains the 50mA output current specification and SOT-23-5 package footprint while offering marginally improved dropout voltage characteristics.

For applications requiring increased output current capacity: Select MIC5255-2.8YM5-TR for SOT-23-5 package compatibility or MIC5255-2.8YD5-TR for TSOT-23-5 thin package variant. Both deliver 150mA output current with enhanced PSRR and integrated Under Voltage Lockout protection.

For maximum output current capacity with superior noise rejection: Select MIC5323-2.8YD5-TR, which provides 300mA output current and 80dB PSRR performance in TSOT-23-5 package. Note the reduced maximum input voltage specification of 5.5V versus 6V for the original part.

Frequently Asked Questions (FAQ)

Q: Can MIC5255-2.8YD5-TR replace TC2014-2.8VCTTR directly on the PCB?

A: MIC5255-2.8YD5-TR uses TSOT-23-5 package while TC2014-2.8VCTTR uses standard SOT-23-5. Pin configuration is identical, but the TSOT variant has reduced physical dimensions. PCB footprint modification is required. Use MIC5255-2.8YM5-TR for direct SOT-23-5 footprint compatibility.

Q: What is the difference between SOT-23-5 and TSOT-23-5 packages?

A: TSOT-23-5 is a thin variant of SOT-23-5 with identical pin spacing and configuration but reduced overall height. Both are surface mount packages suitable for the same electrical applications. Verify PCB assembly equipment compatibility before selecting TSOT variants.

Q: Is MIC5323-2.8YD5-TR suitable for all TC2014-2.8VCTTR applications?

A: MIC5323-2.8YD5-TR is electrically compatible for applications requiring up to 300mA output current. However, its maximum input voltage is 5.5V compared to 6V for the original part. Verify your input voltage specification does not exceed 5.5V before substitution.

Q: Do all substitute parts include Enable control functionality?

A: Yes. All listed substitute parts include Enable control features matching the original TC2014-2.8VCTTR specification.

Q: What additional protection does UVLO (Under Voltage Lockout) provide?

A: Under Voltage Lockout protection prevents regulator operation when input voltage falls below a specified threshold, protecting downstream circuitry from unstable supply conditions. MIC5255 series parts include this feature; TC2014 and TC1014 do not.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance and REACH unaffected status, matching the regulatory certification of the original TC2014-2.8VCTTR.
