PQ1T301M2ZP Equivalent & Substitute Parts

Part Overview

The PQ1T301M2ZP is a switching regulator IC manufactured by Sharp Microelectronics, designed for power management applications with a 3V output and 150mA capacity in SOT-23-5 packaging. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, design updates, and production continuity. The part's discontinuation necessitates evaluation of substitute components that maintain electrical and mechanical compatibility with existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the PQ1T301M2ZP are identified based on the following critical parameters that determine functional equivalence:

• Output Voltage: 3V fixed output
• Package Type: SOT-23-5 (SC-74A, SOT-753)
• Mounting Type: Surface Mount
• Output Configuration: Positive fixed output
• Regulatory Compliance: RoHS status and ECCN classification

The TPS76930DBVT from Texas Instruments meets these substitution criteria as a linear voltage regulator with identical 3V output voltage and SOT-23-5 packaging. While the TPS76930DBVT provides 100mA output current compared to the original 150mA specification, it operates within the same voltage class and physical form factor, making it suitable for applications where the reduced current capacity is acceptable.

Engineering Selection Recommendations

Selection of the TPS76930DBVT as a substitute for the PQ1T301M2ZP is based on the following engineering considerations:

Compliance Status: The TPS76930DBVT holds ROHS3 compliance, whereas the original PQ1T301M2ZP is RoHS non-compliant. For new designs or systems requiring regulatory compliance with current environmental standards, the TPS76930DBVT provides the necessary certification alignment.

Product Lifecycle: The PQ1T301M2ZP is classified as obsolete with no ongoing manufacturing. The TPS76930DBVT, designated as Last Time Buy, provides a defined procurement window for transition planning.

Electrical Compatibility: Both components share identical 3V output voltage and SOT-23-5 packaging, ensuring mechanical and electrical pin compatibility. The primary design consideration is the output current specification: applications requiring the full 150mA capacity of the original part must be evaluated against the 100mA limitation of the substitute.

Regulatory Classification: Both parts carry EAR99 ECCN classification and HTSUS code 8542.39.0001, maintaining consistent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the TPS76930DBVT directly replace the PQ1T301M2ZP in existing designs?

A: Direct replacement is possible from a mechanical and voltage perspective, as both components use SOT-23-5 packaging and provide 3V output. However, the output current capacity differs: the substitute provides 100mA versus the original 150mA. Designs operating at or near the 150mA limit require current load analysis to confirm compatibility.

Q: What is the significance of the RoHS compliance difference?

A: The PQ1T301M2ZP is RoHS non-compliant, while the TPS76930DBVT is ROHS3 compliant. For applications subject to RoHS regulations or customer requirements mandating compliant components, the TPS76930DBVT satisfies these requirements. Existing legacy systems may continue using non-compliant parts if regulatory exemptions apply.

Q: Are there pin-to-pin compatibility concerns?

A: Both components use the SOT-23-5 package type (SC-74A, SOT-753 designation). Pin compatibility is maintained for standard LDO regulator configurations. PCB layout and thermal considerations remain unchanged between the two parts.

Q: What is the Last Time Buy status for the TPS76930DBVT?

A: Last Time Buy indicates a defined final procurement period before the manufacturer discontinues production. This status provides a transition window for design updates and inventory planning. Customers should establish procurement timelines accordingly.

Q: How do the quiescent current and dropout voltage specifications compare?

A: The TPS76930DBVT specifies 28 µA quiescent current and 0.23V maximum dropout at 100mA. These parameters are not provided for the PQ1T301M2ZP in the available documentation. For applications sensitive to standby power consumption or operating near minimum input voltage margins, the TPS76930DBVT specifications should be evaluated against system requirements.
