MPQ20056GG-33-Z Equivalent & Substitute Parts

Part Overview

The MPQ20056GG-33-Z is a linear voltage regulator IC from Monolithic Power Systems Inc., designed to deliver a fixed 3.3V output at 250mA with a maximum dropout voltage of 0.2V. This positive fixed output regulator operates across an input range up to 5.5V and includes integrated protection features for over-current, over-temperature, and under-voltage lockout conditions. The device is housed in an 8-QFN (2x2) surface mount package with an exposed pad and is actively produced. Identifying equivalent substitute parts is essential for supply chain continuity, design flexibility, and procurement optimization when the primary part number becomes unavailable or when alternative packaging or qualification requirements are needed.

Substitute Part Grouping Explanation

Substitution of the MPQ20056GG-33-Z is determined by strict equivalence across the following electrical and mechanical parameters:

Fixed output voltage of 3.3V
Output current capability of 250mA
Maximum input voltage of 5.5V
Dropout voltage specification of 0.2V @ 250mA
Identical package configuration: 8-QFN (2x2) with exposed pad
Matching protection feature set: over-current, over-temperature, and UVLO
Operating temperature range of -40°C to 125°C
ROHS3 compliance and MSL 1 rating

The MPQ20056GG-33-AEC1-Z qualifies as a parametric equivalent substitute. This variant maintains all electrical specifications and package geometry while adding automotive-grade qualification (AEC-Q100) and is available in alternative packaging formats (Cut Tape and Digi-Reel).

Engineering Selection Recommendations

Both the MPQ20056GG-33-Z and MPQ20056GG-33-AEC1-Z are active products from Monolithic Power Systems Inc. with identical electrical performance and package specifications. Selection between these parts should be based on application requirements and supply chain considerations:

The MPQ20056GG-33-Z is suitable for general industrial and consumer applications requiring a 3.3V, 250mA linear regulator with standard product qualification.

The MPQ20056GG-33-AEC1-Z is the appropriate choice for automotive applications, as it carries AEC-Q100 qualification and is available in tape-and-reel packaging formats, which are standard requirements for automotive supply chains. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity level rating, ensuring compatibility with modern manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can the MPQ20056GG-33-AEC1-Z be used as a direct replacement for the MPQ20056GG-33-Z?

A: Yes. The MPQ20056GG-33-AEC1-Z is a parametric equivalent with identical electrical specifications, output voltage, current rating, dropout voltage, protection features, and package configuration. The primary difference is the addition of automotive-grade AEC-Q100 qualification, which does not affect compatibility in non-automotive applications.

Q: What is the difference between the standard and AEC-Q100 qualified versions?

A: The AEC-Q100 qualification indicates the part has undergone automotive-grade reliability testing and qualification procedures. This qualification is required for automotive applications but does not alter the electrical performance or package specifications. Both versions are manufactured by the same company and share identical functional characteristics.

Q: Are the packaging formats interchangeable?

A: The physical package (8-QFN 2x2 with exposed pad) is identical between both parts. The MPQ20056GG-33-AEC1-Z is additionally available in Cut Tape and Digi-Reel packaging formats, which are standard for high-volume production and automotive supply chains. The component itself remains the same; only the delivery format differs.

Q: What are the key parameters that define substitution eligibility?

A: Substitution is determined by matching output voltage (3.3V fixed), output current (250mA), input voltage rating (5.5V max), dropout voltage (0.2V @ 250mA), package type (8-QFN 2x2), protection features (over-current, over-temperature, UVLO), and operating temperature range (-40°C to 125°C). Any deviation in these parameters disqualifies a part as a direct substitute.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the MPQ20056GG-33-Z and MPQ20056GG-33-AEC1-Z are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating, making them suitable for standard PCB assembly processes without special handling requirements.
