MP2172GJ-Z Equivalent & Substitute Parts

Part Overview

The MP2172GJ-Z is a buck switching regulator IC manufactured by Monolithic Power Systems Inc., classified as a Power Management (PMIC) component. This device functions as a step-down converter with positive adjustable output, delivering 2A maximum output current in a compact SOT-23-8 Thin (TSOT-23-8) surface mount package. The part is actively produced and RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when design requirements necessitate alternative packaging formats, extended operating temperature ranges, or automotive-grade qualifications while maintaining electrical and mechanical compatibility with the MP2172GJ-Z.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP2172GJ-Z are identified based on strict electrical and mechanical parameter matching. All substitute devices maintain identical specifications for:

• Input voltage range (2.5V to 5.5V)
• Output voltage range (0.6V to 5V)
• Output current capability (2A)
• Switching frequency (2.6MHz)
• Synchronous rectifier functionality
• Package type (SOT-23-8 Thin, TSOT-23-8)
• Surface mount mounting type
• RoHS3 compliance
• MSL 1 rating

Substitutes are differentiated by packaging format (Tape & Reel versus Cut Tape & Digi-Reel®), operating temperature range extension, and automotive-grade qualification (AEC-Q100). These variations allow component selection based on supply chain availability, temperature environment requirements, and automotive application demands without altering core electrical performance.

Parameter Comparison

Engineering Selection Recommendations

MP2172GJ-Z is suitable for standard industrial and consumer applications requiring a 2A adjustable buck regulator within the -40°C to 125°C operating range. This part is actively produced with established supply availability.

MPQ2172GJ-P provides identical electrical performance with extended operating temperature capability (-40°C to 150°C) and automotive-grade qualification (AEC-Q100). This variant is appropriate for automotive applications and environments requiring higher temperature operation while maintaining Tape & Reel packaging.

MPQ2172GJ-AEC1-Z delivers the same electrical specifications and automotive qualification as MPQ2172GJ-P with alternative packaging in Cut Tape & Digi-Reel® format. This variant addresses supply chain flexibility and alternative distribution requirements for automotive-qualified designs.

All three parts maintain identical electrical performance, package footprint, and compliance certifications. Selection between them is determined by application grade requirements (standard versus automotive), operating temperature environment, and packaging format availability.

Frequently Asked Questions (FAQ)

Q: Can MPQ2172GJ-P replace MP2172GJ-Z in a standard industrial application?

A: Yes. MPQ2172GJ-P maintains all electrical specifications and package compatibility with MP2172GJ-Z. The extended operating temperature range (-40°C to 150°C versus -40°C to 125°C) and automotive qualification do not restrict use in standard applications.

Q: What is the primary difference between MPQ2172GJ-P and MPQ2172GJ-AEC1-Z?

A: Both parts are electrically and thermally identical with AEC-Q100 automotive qualification. The difference is packaging format: MPQ2172GJ-P uses Tape & Reel (TR) while MPQ2172GJ-AEC1-Z uses Cut Tape (CT) & Digi-Reel®. Selection depends on assembly equipment compatibility and supply chain requirements.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the SOT-23-8 Thin (TSOT-23-8) package with identical pinout and footprint, enabling direct substitution on PCB layouts.

Q: Does the MP2172GJ-Z meet automotive standards?

A: The MP2172GJ-Z is standard grade without automotive qualification. For automotive applications requiring AEC-Q100 compliance, use MPQ2172GJ-P or MPQ2172GJ-AEC1-Z.

Q: What is the significance of the extended temperature range in MPQ2172GJ-P and MPQ2172GJ-AEC1-Z?

A: The extended range (-40°C to 150°C) accommodates higher ambient and junction temperatures typical in automotive underhood environments and industrial applications with thermal constraints. MP2172GJ-Z is rated to 125°C and is suitable for standard temperature environments.

Q: Can these parts be used interchangeably in production?

A: Electrical and mechanical interchangeability is confirmed. However, design documentation and qualification requirements must specify which part number is approved for the application. Automotive designs must use AEC-Q100 qualified variants (MPQ2172GJ-P or MPQ2172GJ-AEC1-Z).

Q: What does RoHS3 compliance indicate?

A: All three parts are RoHS3 compliant, confirming restriction of hazardous substances in accordance with EU Directive 2011/65/EU and amendments. This applies to all variants regardless of grade or packaging format.
