MPQ8904DD-AEC1-LF-Z Equivalent & Substitute Parts

Part Overview

The MPQ8904DD-AEC1-LF-Z 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 automotive-grade qualification (AEC-Q100). The device is currently in active production status with 2400 units in stock.

Substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design revisions call for components with different product lifecycle statuses or performance characteristics within the same functional specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPQ8904DD-AEC1-LF-Z is determined by strict equivalence across the following critical parameters:

• Output Configuration: Positive
• Output Type: Adjustable
• Voltage - Input (Max): 6.5V
• Voltage - Output (Min/Fixed): 0.5V
• Voltage - Output (Max): 5V
• Current - Output: 500mA
• Package / Case: 8-TFDFN Exposed Pad
• Mounting Type: Surface Mount
• Operating Temperature: -40°C ~ 125°C

All identified substitute parts maintain these core electrical and mechanical specifications. Variations exist in quiescent current, dropout voltage characteristics, product status, packaging format (Cut Tape vs. Tape & Reel), and automotive qualification level. These differences do not affect functional interchangeability within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (MPQ8904DD-AEC1-LF-Z): Maintain use of the primary part for automotive applications requiring AEC-Q100 qualification. Active product status ensures long-term availability and manufacturing support.

Alternative MP8904DD-LF-Z: Select this substitute when Cut Tape packaging with Digi-Reel® format is required and automotive qualification is not mandatory. Active product status and higher inventory (16167 units) provide supply continuity. Electrical performance is equivalent with improved dropout voltage characteristics (0.3V typical vs. 0.45V maximum).

Alternative MP8904DD-LF-P: Select this substitute when Tape & Reel (TR) packaging is required for high-volume automated assembly processes. Active product status and equivalent electrical specifications apply. Packaging format is the primary differentiator.

Alternative MP2002DD-LF-Z: This part is functionally equivalent but carries "Not For New Designs" status. Use only for legacy system maintenance or when existing inventory must be consumed. Higher quiescent current efficiency (100 µA vs. 200 µA) and lower typical dropout voltage (0.29V) may provide marginal power savings in specific applications, but product lifecycle status restricts new design implementation.

Frequently Asked Questions (FAQ)

Q: Can MP8904DD-LF-Z replace MPQ8904DD-AEC1-LF-Z in automotive applications?

A: MP8904DD-LF-Z is electrically equivalent and maintains the same package specification. However, it lacks automotive-grade designation and AEC-Q100 qualification. Use only in non-automotive applications or where automotive qualification is not a design requirement.

Q: What is the difference between Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) packaging?

A: Cut Tape format provides individual component strips suitable for manual assembly or small-batch pick-and-place operations. Tape & Reel format supplies components on continuous reels optimized for high-speed automated assembly lines. Electrical specifications remain identical; packaging selection depends on manufacturing process requirements.

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

A: This designation indicates the part is in end-of-life phase. While functionally equivalent and currently in stock (20100 units), Monolithic Power Systems does not recommend its use in new product designs. Existing inventory may be used for legacy system support or maintenance applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 Compliant status, meeting environmental and hazardous substance restrictions.

Q: What is the significance of the quiescent current difference between MPQ8904DD-AEC1-LF-Z (200 µA) and substitute parts (100 µA)?

A: The primary part exhibits higher quiescent current consumption. In battery-powered or low-power standby applications, substitute parts with 100 µA quiescent current provide improved power efficiency. This difference does not affect functional interchangeability but may influence power budget calculations in specific system designs.
