MP20056GG-33-Z Equivalent & Substitute Parts

Part Overview

The MP20056GG-33-Z is a linear voltage regulator IC from Monolithic Power Systems Inc., classified as a Power Management (PMIC) component. This device delivers a fixed 3.3V output at 250mA with integrated protection features including over-current, over-temperature, and under-voltage lockout (UVLO) functionality. The part is currently active in production and available in high volume (1890 pcs in stock). Alternative equivalent parts may be required due to packaging preferences, supply chain considerations, or specific application requirements such as automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP20056GG-33-Z is determined by the following critical parameters:

• Fixed output voltage of 3.3V
• Output current capability of 250mA
• Maximum input voltage of 5.5V
• Package configuration: 8-TFDFN Exposed Pad (8-QFN 2x2)
• Surface mount technology
• Presence of Enable control feature and integrated protection (Over Current, Over Temperature, UVLO)
• Operating temperature range: -40°C to 125°C
• RoHS3 compliance

The MPQ20056GG-33-AEC1-Z qualifies as a parametric equivalent based on these criteria. The primary distinction is the packaging format (Cut Tape & Digi-Reel versus Tape & Reel) and the addition of automotive-grade qualification (AEC-Q100), which does not affect electrical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the MP20056GG-33-Z and MPQ20056GG-33-AEC1-Z are active production parts with ROHS3 compliance and identical core electrical specifications. Selection between these parts should be based on the following criteria:

MP20056GG-33-Z is suitable for general industrial and consumer applications where standard-grade components are acceptable and Tape & Reel packaging is preferred for high-volume automated assembly.

MPQ20056GG-33-AEC1-Z is the appropriate choice for automotive applications requiring AEC-Q100 qualification or when Cut Tape & Digi-Reel packaging is specified. The automotive-grade variant carries the same electrical performance with the addition of automotive-specific qualification testing and documentation.

The voltage dropout specification difference (0.15V versus 0.2V @ 250mA) is within acceptable tolerance for most 3.3V regulation applications and does not preclude substitution in standard designs.

Frequently Asked Questions (FAQ)

Q: Can MPQ20056GG-33-AEC1-Z be used as a direct replacement for MP20056GG-33-Z?

A: Yes. Both parts are electrically equivalent with identical output voltage, current rating, input voltage range, and protection features. The primary differences are packaging format and automotive qualification, which do not affect electrical interchangeability in non-automotive applications.

Q: What is the significance of the AEC-Q100 qualification on the MPQ20056GG-33-AEC1-Z?

A: AEC-Q100 qualification indicates the part has undergone automotive-grade reliability testing and is approved for use in automotive applications. This qualification is not required for non-automotive designs but does not negatively impact performance in other applications.

Q: Are there packaging compatibility considerations between these parts?

A: Both parts use the same 8-TFDFN Exposed Pad (8-QFN 2x2) package and surface mount technology. The difference lies in the supply format: MP20056GG-33-Z is supplied in Tape & Reel (TR), while MPQ20056GG-33-AEC1-Z is supplied in Cut Tape (CT) & Digi-Reel®. PCB footprint and reflow soldering requirements are identical.

Q: Does the voltage dropout difference affect circuit design?

A: The MP20056GG-33-Z specifies 0.15V dropout while the MPQ20056GG-33-AEC1-Z specifies 0.2V dropout at 250mA. For most 3.3V regulation circuits with input voltages well above the minimum required headroom, this 0.05V difference is negligible. Verify dropout performance in designs with tight input voltage margins.

Q: Are both parts currently available?

A: Yes. MP20056GG-33-Z has 1890 pcs in stock, and MPQ20056GG-33-AEC1-Z has 32650 pcs in stock. Both are active production parts.
