MPQ8904DD-AEC1-LF-P Equivalent & Substitute Parts

Part Overview

The MPQ8904DD-AEC1-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 automotive-grade qualification (AEC-Q100). The device features Enable and Power Good control functions, along with Over Current and Over Temperature protection.

This part is currently Active in product status. Substitute parts may be required due to packaging format availability, inventory constraints, or specific application requirements regarding quiescent current and dropout voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPQ8904DD-AEC1-LF-P is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Output Configuration: Positive Adjustable
• Current Output: 500mA
• Voltage Input (Max): 6.5V
• Voltage Output Range: 0.5V to 5V
• Operating Temperature: -40°C ~ 125°C
• Control Features: Enable, Power Good
• Protection Features: Over Current, Over Temperature

Mechanical Compatibility Requirements:

• Package / Case: 8-TFDFN Exposed Pad
• Supplier Device Package: 8-QFN (2x3)
• Mounting Type: Surface Mount

Compliance Requirements:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts must maintain identical electrical output specifications, package footprint, and compliance certifications. Variations in quiescent current, supply current, and dropout voltage are permissible within the specified ranges, as these do not affect functional compatibility in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Automotive Applications):

MPQ8904DD-AEC1-LF-Z is the direct equivalent to MPQ8904DD-AEC1-LF-P. Both parts maintain identical electrical specifications, automotive-grade qualification (AEC-Q100), and identical quiescent/supply current characteristics. The only difference is packaging format: the -LF-P variant is supplied in Tape & Reel (TR) format, while the -LF-Z variant is supplied in Cut Tape (CT) & Digi-Reel® format. Selection between these two depends solely on procurement and assembly line requirements.

Secondary Substitutes (Non-Automotive or Performance-Optimized Applications):

MP8904DD-LF-P and MP8904DD-LF-Z are parametric equivalents suitable for applications where automotive qualification is not required. These parts deliver superior performance characteristics: quiescent current of 100 µA (versus 200 µA) and supply current of 5 mA (versus 12 mA), resulting in lower power consumption. Dropout voltage is 0.3V typical at 500mA, compared to 0.45V maximum for the MPQ8904DD variants. Both MP8904 variants are Active in product status and maintain identical package footprint and electrical output range.

Legacy Substitute (Not Recommended for New Designs):

MP2002DD-LF-Z is a parametric equivalent with superior electrical performance (0.29V typical dropout voltage, 100 µA quiescent current, 5 mA supply current). However, this part carries a "Not For New Designs" product status designation. Use of this part is restricted to legacy system maintenance or replacement applications only.

Frequently Asked Questions (FAQ)

Q: Can I substitute MPQ8904DD-AEC1-LF-P with MP8904DD-LF-P in an automotive application?

A: No. The MPQ8904DD-AEC1-LF-P carries automotive-grade qualification (AEC-Q100) and is designated as Automotive grade. The MP8904DD-LF-P does not carry automotive qualification. For automotive applications, use only MPQ8904DD-AEC1-LF-Z or MPQ8904DD-AEC1-LF-P.

Q: What is the difference between the -LF-P and -LF-Z packaging variants?

A: The -LF-P variant is supplied in Tape & Reel (TR) format, suitable for high-volume automated assembly. The -LF-Z variant is supplied in Cut Tape (CT) & Digi-Reel® format. Both variants are electrically identical and use the same 8-TFDFN Exposed Pad package footprint. Selection depends on your procurement and assembly process requirements.

Q: Are the MP8904DD variants suitable as drop-in replacements for MPQ8904DD-AEC1-LF-P?

A: The MP8904DD variants are electrically compatible and use the identical package footprint. However, they lack automotive-grade qualification. They are suitable as drop-in replacements only in non-automotive applications or where automotive qualification is not a design requirement.

Q: Why does MP2002DD-LF-Z have a "Not For New Designs" status?

A: The MP2002DD-LF-Z is a legacy part. While it remains parametrically equivalent and electrically compatible, Monolithic Power Systems Inc. has designated this part as unsuitable for new design implementations. This part should be used only for replacement or maintenance of existing systems.

Q: Can I use MP8904DD-LF-Z instead of MPQ8904DD-AEC1-LF-P if I need lower quiescent current?

A: The MP8904DD-LF-Z does deliver lower quiescent current (100 µA versus 200 µA) and lower supply current (5 mA versus 12 mA). However, it lacks automotive-grade qualification. Use this part only if your application does not require automotive qualification and you have verified that the lower quiescent current is compatible with your power budget requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 Compliant status and Moisture Sensitivity Level (MSL) 1 (Unlimited), matching the compliance profile of the MPQ8904DD-AEC1-LF-P.
