Equivalent current output of 500mA
Identical package type: 8-QFN (2x3) with 8-TFDFN Exposed Pad
Matching control features (Enable, Power Good) and protection features (Over Current, Over Temperature)
Operating temperature range of -40°C ~ 125°C
ROHS3 compliance and MSL 1 rating

The substitute parts are grouped into two categories based on product status and automotive qualification:

Category 1: Standard Industrial Grade (Active Status)

MP8904DD-LF-P
MP8904DD-LF-Z

Category 2: Automotive Grade with AEC-Q100 Qualification (Active Status)

MPQ8904DD-AEC1-LF-P

Engineering Selection Recommendations

For applications currently using the MP2002DD-LF-Z, the MP8904DD series represents the direct active replacement with minimal performance variation. The MP8904DD-LF-Z maintains identical quiescent current (100 µA) and supply current (5 mA) specifications with marginally higher dropout voltage (0.3V vs. 0.29V), making it suitable for most industrial applications requiring Cut Tape packaging.

For automotive applications or systems requiring AEC-Q100 qualification, the MPQ8904DD series provides certified alternatives. These parts exhibit higher quiescent current (200 µA) and supply current (12 mA) with increased dropout voltage (0.45V), reflecting automotive-grade design margins. Selection between AEC1-qualified and non-qualified MPQ8904DD variants depends on specific automotive compliance requirements.

Packaging format selection between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® variants should align with procurement and assembly processes. All substitute parts maintain ROHS3 compliance and MSL 1 rating consistent with the original MP2002DD-LF-Z.

Frequently Asked Questions (FAQ)

Q: Can MP8904DD-LF-Z directly replace MP2002DD-LF-Z in existing designs?

A: Yes. Both parts share identical electrical specifications for output configuration, voltage range, current output, control features, and protection features. The 0.01V increase in maximum dropout voltage (0.3V vs. 0.29V) is within typical design margins for adjustable linear regulators. Packaging format (Cut Tape & Digi-Reel®) is identical.

Q: What is the difference between MP8904DD and MPQ8904DD series?

A: The MP8904DD series is industrial-grade with 100 µA quiescent current and 5 mA maximum supply current. The MPQ8904DD series includes automotive-grade variants with AEC-Q100 qualification, featuring 200 µA quiescent current and 12 mA maximum supply current. The MPQ8904DD-AEC1 variants carry explicit automotive qualification; non-AEC1 MPQ8904DD parts are industrial-grade despite the MPQ designation.

Q: Does packaging format affect electrical performance?

A: No. Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) packaging formats deliver identical electrical performance. Selection depends on procurement method and assembly line compatibility. The 8-QFN (2x3) package geometry and pin configuration remain constant across all variants.

Q: Are all substitute parts currently in active production?

A: Yes. All listed substitute parts carry "Active" product status, ensuring ongoing availability and manufacturing support. The original MP2002DD-LF-Z is marked "Not For New Designs," making transition to active alternatives necessary for long-term supply chain continuity.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. The MPQ8904DD-AEC1 variants additionally carry AEC-Q100 automotive qualification. REACH status is "REACH Unaffected" for all parts.
