Substitute Part Grouping Explanation

Substitution eligibility for the MP2181GTL-Z is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications in the following critical categories:

Electrical Parameters:

• Input voltage range: 2.5V to 5.5V
• Output voltage range: 0.6V to 5.5V
• Output current capacity: 1A
• Switching frequency: 1.2MHz
• Synchronous rectifier functionality: Present

Mechanical Parameters:

• Package type: SOT-583
• Mounting type: Surface Mount
• Physical footprint compatibility

Regulatory & Compliance Parameters:

• RoHS3 compliance
• REACH unaffected status
• Moisture sensitivity level: 1
• ECCN and HTSUS classifications

The MP2181GTL-Z and MP2181GTL-P share the same base product number (MP2181) and differ only in packaging designation (tape & reel variant codes). Both devices are manufactured by Monolithic Power Systems Inc. and maintain identical electrical performance specifications, topology, and regulatory certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the MP2181GTL-Z and MP2181GTL-P are active products from Monolithic Power Systems Inc. with full regulatory compliance. Selection between these parts is based on inventory availability and packaging designation requirements rather than electrical or mechanical differences.
