Substitute Part Grouping Explanation

Substitute parts for the MPQ2013AGQ-18-Z are identified as parametric equivalents within the MPQ2013 base product family. Substitution is valid when the following electrical and mechanical parameters remain identical:

Output voltage: 1.8V fixed
Output current capability: 150mA
Input voltage rating: 40V maximum
Dropout voltage: 1.1V @ 100mA
Package type: 8-VDFN Exposed Pad (8-QFN 3x3)
Operating temperature range: -40°C to 125°C
Control and protection features: Enable, Over Current, Over Temperature
Compliance certifications: ROHS3, MSL 1

The identified substitutes differ only in packaging configuration (Tape & Reel vs. bulk) and suffix designations, which indicate manufacturing date codes or qualification variants. All parts maintain identical electrical performance and thermal characteristics.

Engineering Selection Recommendations

All three parts—MPQ2013AGQ-18-Z, MPQ2013AGQ-18-AEC1-P, and MPQ2013AGQ-18-AEC1-Z—are active production devices with identical electrical specifications and thermal performance. Selection between these parts is determined by packaging and supply requirements:

MPQ2013AGQ-18-Z: Bulk packaging configuration. Select when component-level inventory management or custom tape/reel consolidation is preferred.
MPQ2013AGQ-18-AEC1-P: Tape & Reel packaging. Select for automated assembly line integration and standard pick-and-place operations.
MPQ2013AGQ-18-AEC1-Z: Tape & Reel packaging with highest current inventory (932 units). Select for immediate availability and high-volume production runs.

All parts carry ROHS3 compliance and MSL 1 rating, confirming suitability for standard surface-mount assembly processes without moisture bake-out requirements. No functional or thermal derating applies across these substitutes.

Frequently Asked Questions (FAQ)

Q: Can MPQ2013AGQ-18-AEC1-P and MPQ2013AGQ-18-AEC1-Z be used interchangeably with MPQ2013AGQ-18-Z?

A: Yes. All three parts deliver identical electrical performance, output voltage, current capacity, and thermal characteristics. The suffix designations and packaging configurations are the only differences. Schematic and PCB layout compatibility is maintained across all three variants.

Q: What is the difference between the packaging configurations?

A: MPQ2013AGQ-18-Z is supplied in bulk form. MPQ2013AGQ-18-AEC1-P and MPQ2013AGQ-18-AEC1-Z are supplied in Tape & Reel (TR) configuration, which is standard for automated surface-mount assembly. The electrical device itself is identical.

Q: Are there any thermal or performance differences between these parts?

A: No. All three parts operate within the same temperature range (-40°C to 125°C), maintain identical dropout voltage (1.1V @ 100mA), quiescent current (10 µA), and PSRR characteristics (58dB ~ 41dB, 100Hz ~ 1kHz).

Q: Which part should I select for high-volume production?

A: MPQ2013AGQ-18-AEC1-Z is recommended for high-volume production due to highest current inventory (932 units) and Tape & Reel packaging compatibility with standard pick-and-place equipment.

Q: Do all parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, carry MSL 1 rating (unlimited moisture sensitivity), and are REACH unaffected. No additional qualification or testing is required when substituting between these parts.

Q: Can I mix packaging types in a single production run?

A: Mixing bulk and Tape & Reel packaging in a single production run is possible but not recommended for automated assembly. Standardize on Tape & Reel (MPQ2013AGQ-18-AEC1-P or MPQ2013AGQ-18-AEC1-Z) for consistent pick-and-place operation.
