MPQ8904DD-LF-P Equivalent & Substitute Parts

Part Overview

The MPQ8904DD-LF-P is a linear voltage regulator IC from Monolithic Power Systems Inc., classified as a Power Management (PMIC) component. This positive adjustable regulator delivers 500mA output current in an 8-QFN (2x3) surface mount package with integrated enable and power good control features, along with over-current and over-temperature protection. The part is currently in active production status with 739 units in stock.

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design requirements necessitate different electrical characteristics such as lower quiescent current or improved dropout voltage performance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MPQ8904DD-LF-P are determined by strict equivalence across the following critical parameters:

• Output configuration (Positive)
• Output type (Adjustable)
• Number of regulators (1)
• Maximum input voltage (6.5V)
• Output voltage range (0.5V to 5V)
• Output current capability (500mA)
• Control features (Enable, Power Good)
• Protection features (Over Current, Over Temperature)
• Operating temperature range (-40°C ~ 125°C)
• Package type (8-QFN 2x3)
• RoHS compliance (ROHS3)

Substitute parts may differ in packaging format (Tape & Reel versus Cut Tape & Digi-Reel), quiescent current, supply current, dropout voltage specifications, product status, and automotive qualification. These differences do not affect functional equivalence when the core electrical and mechanical parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

MP8904DD-LF-P and MP8904DD-LF-Z are direct functional equivalents to the MPQ8904DD-LF-P. Both parts share identical electrical specifications with improved quiescent current (100 µA versus 200 µA) and reduced maximum supply current (5 mA versus 12 mA). MP8904DD-LF-P maintains Tape & Reel packaging identical to the primary part, while MP8904DD-LF-Z uses Cut Tape & Digi-Reel packaging. Both are in active production status.

MP2002DD-LF-Z is a parametric equivalent with the lowest dropout voltage specification (0.29V typical @ 500mA) and lowest quiescent current (100 µA). However, this part carries a "Not For New Designs" product status, limiting its suitability for new development projects. It is available only in Cut Tape & Digi-Reel packaging.

MPQ8904DD-AEC1-LF-Z is an automotive-grade variant qualified to AEC-Q100 standards. It maintains identical electrical specifications to the primary MPQ8904DD-LF-P part and is available in Cut Tape & Digi-Reel packaging. This variant is appropriate for automotive applications requiring automotive-grade components.

For standard industrial applications requiring Tape & Reel packaging and active product status, MP8904DD-LF-P is the primary substitute. For applications requiring Cut Tape & Digi-Reel packaging with improved power efficiency, MP8904DD-LF-Z is appropriate. For automotive applications, MPQ8904DD-AEC1-LF-Z is the designated substitute.

Frequently Asked Questions (FAQ)

Q: Can MP8904DD-LF-P be used as a direct replacement for MPQ8904DD-LF-P?

A: Yes. Both parts are functionally equivalent across all critical electrical parameters: 500mA output current, 0.5V to 5V adjustable output range, 6.5V maximum input voltage, Enable and Power Good control features, and identical package type (8-QFN 2x3). The primary difference is improved quiescent current (100 µA versus 200 µA) and reduced supply current (5 mA versus 12 mA) in the MP8904DD-LF-P variant.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) & Digi-Reel packaging supplies components on cut tape segments or alternative reel formats, typically used for lower-volume production or mixed-component orders. Both formats contain identical components in the same 8-QFN (2x3) package.

Q: Why is MP2002DD-LF-Z marked "Not For New Designs"?

A: The "Not For New Designs" status indicates that this part number is in the end-of-life phase and is no longer recommended for new product development. While functionally equivalent, it should be avoided in new designs to ensure long-term supply availability and support.

Q: Is MPQ8904DD-AEC1-LF-Z suitable for non-automotive applications?

A: Yes. The MPQ8904DD-AEC1-LF-Z automotive-grade variant meets all electrical and mechanical requirements for standard industrial applications. The AEC-Q100 qualification represents an additional quality and reliability standard that exceeds standard industrial requirements, making it suitable for any application requiring the specified electrical characteristics.

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

A: Substitution eligibility is determined by equivalence across output configuration (Positive), output type (Adjustable), number of regulators (1), input voltage rating (6.5V maximum), output voltage range (0.5V to 5V), output current (500mA), control features (Enable, Power Good), protection features (Over Current, Over Temperature), operating temperature range (-40°C to 125°C), and package type (8-QFN 2x3). Variations in quiescent current, supply current, dropout voltage, packaging format, and product status do not affect functional substitution.
