MP2207DN-LF-Z Equivalent & Substitute Parts

Part Overview

The MP2207DN-LF-Z is a buck switching regulator IC manufactured by Monolithic Power Systems Inc., designed for positive adjustable output applications. This device operates as a step-down converter with a single adjustable output, delivering up to 4A of output current across an input voltage range of 3V to 16V. The part is housed in an 8-SOIC package with exposed pad and features a synchronous rectifier for improved efficiency.

The MP2207DN-LF-Z carries a "Not For New Designs" product status, indicating that the manufacturer no longer recommends this part for new circuit development. This status necessitates identification of functionally equivalent alternatives that meet current design requirements while maintaining compatibility with existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MP2207DN-LF-Z is determined by the following critical parameters:

• Topology & Function: Buck (step-down) switching regulator with positive adjustable output
• Package Compatibility: 8-SOIC with exposed pad, surface mount
• Output Voltage Range: Minimum 0.8V adjustable output capability
• Output Current Capacity: Minimum 4A rated output current
• Input Voltage Compatibility: Overlap with 3V to 16V input range
• Synchronous Rectification: Presence of integrated synchronous rectifier
• Operating Temperature Range: -40°C to 85°C
• Regulatory Compliance: ROHS3 compliance and EAR99 classification

The RT8072GSP qualifies as a manufacturer-recommended substitute based on functional equivalence in topology, package form factor, and core electrical characteristics. Both devices employ buck topology with adjustable positive output, synchronous rectification, and identical package specifications.

Parameter Comparison

Engineering Selection Recommendations

The RT8072GSP is designated as the manufacturer-recommended substitute for the MP2207DN-LF-Z. Both devices share identical package specifications (8-SOIC with exposed pad), matching operating temperature ranges (-40°C to 85°C), and equivalent regulatory compliance (ROHS3 Compliant, EAR99 classification).

Key compatibility considerations:

• Input Voltage Range Limitation: The RT8072GSP operates within a narrower input voltage window (2.9V to 5.5V) compared to the MP2207DN-LF-Z (3V to 16V). Applications requiring input voltages above 5.5V are incompatible with the RT8072GSP.
• Output Voltage Range Limitation: The RT8072GSP maximum output voltage is 3.3V, whereas the MP2207DN-LF-Z supports output voltages up to 14.4V. Applications requiring adjustable outputs above 3.3V cannot use the RT8072GSP.
• Output Current Enhancement: The RT8072GSP provides 5A output current capacity, exceeding the MP2207DN-LF-Z specification of 4A.
• Switching Frequency Range: The RT8072GSP offers a wider switching frequency range (300kHz to 2MHz) compared to the fixed 1.3MHz of the MP2207DN-LF-Z.
• Moisture Sensitivity: The RT8072GSP carries MSL rating 3 (168 hours) versus the MP2207DN-LF-Z MSL rating 2A (4 weeks), indicating different moisture handling requirements during storage and assembly.

Selection of the RT8072GSP is appropriate only for applications where the input voltage does not exceed 5.5V and the required output voltage does not exceed 3.3V.

Frequently Asked Questions (FAQ)

Q: Can the RT8072GSP directly replace the MP2207DN-LF-Z in all applications?

A: No. The RT8072GSP has restricted input and output voltage ranges. Direct substitution is only valid for applications operating within 2.9V to 5.5V input and 0.8V to 3.3V output specifications.

Q: What is the primary reason for seeking a substitute for the MP2207DN-LF-Z?

A: The MP2207DN-LF-Z carries "Not For New Designs" status from the manufacturer, indicating end-of-life or obsolescence for new circuit development. The RT8072GSP is the manufacturer-recommended alternative.

Q: Are the package dimensions identical between these two parts?

A: Yes. Both the MP2207DN-LF-Z and RT8072GSP use the 8-SOIC package with 0.154" (3.90mm) width and exposed pad. PCB footprints are compatible.

Q: What are the differences in switching frequency between these regulators?

A: The MP2207DN-LF-Z operates at a fixed 1.3MHz switching frequency. The RT8072GSP operates across a range of 300kHz to 2MHz, providing flexibility in frequency selection based on application requirements.

Q: How do the output current ratings compare?

A: The RT8072GSP provides 5A output current capacity, which exceeds the MP2207DN-LF-Z specification of 4A. This represents an improvement in current delivery capability.

Q: Are there moisture sensitivity differences between these parts?

A: Yes. The MP2207DN-LF-Z has MSL rating 2A (4 weeks), while the RT8072GSP has MSL rating 3 (168 hours). Different moisture handling and storage protocols apply to each part.

Q: What operating temperature ranges do these regulators support?

A: Both the MP2207DN-LF-Z and RT8072GSP operate across identical temperature ranges of -40°C to 85°C (TA).

Q: Are both parts RoHS compliant?

A: Yes. Both the MP2207DN-LF-Z and RT8072GSP are ROHS3 compliant and carry EAR99 export classification.
