Key Parameters

Substitute Part Grouping Explanation

The MP26124GR-P qualifies as a parametric equivalent to the MP26124GR-Z based on identical specifications across all critical substitution criteria:

• Battery chemistry and cell count (Lithium Ion, 4-cell)
• Maximum charging current (2A)
• Battery pack voltage (16.8V)
• Supply voltage rating (24V maximum)
• Operating temperature range (125°C TJ)
• Package configuration (16-VQFN Exposed Pad, Surface Mount)
• Fault protection features (Over Current, Over Temperature)
• Programmable functionality (Current, Timer)
• Compliance certifications (ROHS3, REACH Unaffected)

Both parts share the same base product number (MP26124) and are manufactured by Monolithic Power Systems Inc. The substitution is valid for applications where these electrical and mechanical parameters define the design requirement.

Parameter Comparison

Engineering Selection Recommendations
