Critical Matching Parameters:

• Output Type: N-Channel
• Output Configuration: High Side
• Ratio - Input:Output: 1:1
• Current - Output (Max): 5A
• Voltage - Load: 10V ~ 18V
• Rds On (Typ): 40mOhm
• Operating Temperature Range: -40°C ~ 125°C (TJ)
• Package / Case: 10-VFDFN Exposed Pad
• Mounting Type: Surface Mount

All identified substitutes maintain identical electrical performance characteristics and physical package specifications, ensuring direct functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both MP5000ADQ-LF-P and MP5000ADQ-LF-Z are direct functional equivalents to the MP5000SDQ-LF-P. The primary distinction between these substitutes is product status and packaging format.

MP5000ADQ-LF-P carries Active product status, making it the preferred choice for new production runs and long-term supply chain planning. This part is supplied in Tape & Reel (TR) packaging, consistent with the original MP5000SDQ-LF-P format.

MP5000ADQ-LF-Z also maintains Active product status and is supplied in Cut Tape (CT) & Digi-Reel® packaging. This variant offers higher current inventory availability (16,901 Pcs) compared to the Tape & Reel version (2,727 Pcs), making it suitable for immediate procurement needs where packaging format flexibility is acceptable.

Both substitutes maintain full compliance with ROHS3 and REACH requirements, ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can MP5000ADQ-LF-P and MP5000ADQ-LF-Z be used interchangeably with MP5000SDQ-LF-P?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output characteristics, fault protection features, and package dimensions. The only differences are product status (both Active versus Not For New Designs) and packaging format (Tape & Reel versus Cut Tape & Digi-Reel).

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

A: Tape & Reel packaging supplies components on continuous carrier tape in reel format, optimized for automated assembly lines. Cut Tape & Digi-Reel® packaging provides components on cut tape segments with optional reel availability, suitable for lower-volume production or mixed-component orders. Both formats contain the same component in the same 10-QFN (3x3) package.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. All three parts share identical thermal operating range (-40°C ~ 125°C TJ), on-resistance (40mOhm typical), current rating (5A maximum), and voltage specifications (10V ~ 18V load voltage).

Q: Which substitute should I select for new designs?

A: Either MP5000ADQ-LF-P or MP5000ADQ-LF-Z is acceptable for new designs, as both carry Active product status. Selection should be based on packaging preference and supply chain requirements. MP5000ADQ-LF-P is recommended if Tape & Reel format is required; MP5000ADQ-LF-Z is recommended if Cut Tape format or higher inventory availability is prioritized.

Q: Do these substitutes require any PCB layout or schematic modifications?

A: No. The identical package footprint (10-VFDFN Exposed Pad), pin configuration, and electrical characteristics ensure direct drop-in compatibility without design changes.
