Key Parameters

Substitute Part Grouping Explanation

The MP2633GR-P qualifies as a parametric equivalent to the MP2633GR-Z based on identical specifications across all critical electrical and mechanical parameters. Both parts share the same base product number (MP2633), manufacturer (Monolithic Power Systems Inc.), and are classified within the same product family. Substitution eligibility is determined by matching the following parameters:

• Battery chemistry and cell count (Lithium Ion/Polymer, 1 cell)
• Maximum charging current (1.5A)
• Battery pack voltage (4.2V)
• Supply voltage rating (6V maximum)
• Package type and pin configuration (24-VFQFN Exposed Pad)
• Operating temperature range (-40°C ~ 125°C)
• Fault protection features (Over Temperature, Short Circuit)
• Programmable features (Timer)
• Compliance certifications (ROHS3, REACH Unaffected)

The difference between MP2633GR-Z and MP2633GR-P lies exclusively in packaging format: MP2633GR-Z is supplied in Cut Tape (CT), while MP2633GR-P is also supplied in Cut Tape (CT). Both variants are electrically and mechanically identical.

Parameter Comparison

Engineering Selection Recommendations

Both MP2633GR-Z and MP2633GR-P are active products with identical electrical specifications and compliance certifications. Selection between these parts should be based on packaging availability and supply chain requirements. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in applications subject to environmental restrictions. The MSL rating of 1 (Unlimited) indicates minimal moisture sensitivity, reducing handling and storage constraints during manufacturing. Component selection should prioritize whichever variant offers superior inventory availability and lead time performance for your production schedule.
