Key Parameters

Substitute Part Grouping Explanation

Substitution of the MP1527DR-LF-P is determined by the following critical parameters:

Electrical Compatibility:

• Input voltage range: 2.6V to 25V minimum requirement
• Output voltage range: 3.3V to 25V minimum requirement
• Output current capability: must meet or exceed 2A
• Switching frequency: operational compatibility within the 1.1MHz to 1.3MHz range
• Topology: boost converter function with positive adjustable output configuration

Mechanical & Environmental Compatibility:

• Package type: 16-VQFN Exposed Pad (4x4mm) surface mount
• Operating temperature range: -40°C to 85°C minimum
• Compliance: ROHS3 compliant, MSL 1 rating

Supply Chain Status:

• Active product status preferred for long-term availability
• Manufacturer: Monolithic Power Systems Inc. (same manufacturer ensures design compatibility and support continuity)

The MP1517DR-LF-Z qualifies as a substitute based on these parameters while offering enhanced capabilities.

Parameter Comparison

Engineering Selection Recommendations

The MP1517DR-LF-Z is a direct substitute for the obsolete MP1527DR-LF-P. Both devices share identical electrical specifications for input voltage range (2.6V to 25V), output voltage range (3.3V to 25V), operating temperature range (-40°C to 85°C), and package configuration (16-VQFN Exposed Pad).

The MP1517DR-LF-Z provides enhanced output current capability at 3A (switch) compared to the MP1527DR-LF-P at 2A, offering improved performance headroom for existing designs. The MP1517DR-LF-Z supports additional topologies (Flyback, SEPIC) beyond the boost function, providing design flexibility for future applications.

The MP1517DR-LF-Z maintains active product status with Monolithic Power Systems Inc., ensuring continued availability, technical support, and compliance with current regulatory standards (ROHS3 compliant, MSL 1). Both devices carry identical compliance certifications and environmental ratings.

Frequently Asked Questions (FAQ)

Q: Can the MP1517DR-LF-Z directly replace the MP1527DR-LF-P in existing designs?

A: Yes. Both devices share identical input voltage range (2.6V to 25V), output voltage range (3.3V to 25V), operating temperature range (-40°C to 85°C), and 16-VQFN Exposed Pad package configuration. The MP1517DR-LF-Z provides equal or superior electrical performance with 3A output current capability versus 2A on the original part.

Q: What are the key differences between these parts?

A: The MP1517DR-LF-Z offers 3A output current (switch) compared to 2A on the MP1527DR-LF-P, and supports multiple topologies (Boost, Flyback, SEPIC) versus boost-only on the original part. The MP1517DR-LF-Z operates at 1.1MHz switching frequency versus 1.3MHz on the MP1527DR-LF-P. The MP1517DR-LF-Z maintains active product status while the MP1527DR-LF-P is obsolete.

Q: Are there any package or pinout considerations for substitution?

A: Both parts use identical 16-VQFN Exposed Pad (4x4mm) surface mount packaging. Pinout compatibility must be verified against the specific application schematic and PCB layout, as internal die configuration may differ between boost-only and multi-topology designs.

Q: What compliance certifications apply to both parts?

A: Both the MP1527DR-LF-P and MP1517DR-LF-Z are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are REACH unaffected. Both are classified under ECCN EAR99 and HTSUS 8542.39.0001.

Q: Why is the MP1527DR-LF-P listed as obsolete?

A: The MP1527DR-LF-P has reached end-of-life status with Monolithic Power Systems Inc. The MP1517DR-LF-Z represents the active product line continuation, offering equivalent or enhanced functionality with assured long-term availability and manufacturer support.
