Key Parameters

Substitute Part Grouping Explanation

The MP26057DQ-LF-Z has one parametric equivalent substitute: MP26057DQ-LF-P. Both parts are manufactured by Monolithic Power Systems Inc. and share identical electrical and mechanical specifications across all critical parameters that determine functional substitutability:

• Battery chemistry and cell count (Lithium Ion/Polymer, 1 cell)
• Maximum charging current (1A)
• Battery pack voltage (4.2V)
• Maximum supply voltage (5.5V)
• USB interface
• Operating temperature range (-40°C ~ 85°C)
• Package type and form factor (10-QFN 3x3, 10-VFDFN Exposed Pad)
• Programmable features (Timer)
• Fault protection (Over Temperature)
• Compliance certifications (ROHS3, REACH Unaffected, EAR99)

The substitution is based on identical parametric alignment across all provided specifications. Both parts belong to the same base product family (MP26057) and differ only in packaging designation (tape & reel format).

Parameter Comparison

Engineering Selection Recommendations

Both MP26057DQ-LF-Z and MP26057DQ-LF-P are active products from Monolithic Power Systems Inc. with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• Inventory availability and lead time requirements
• Packaging format preference (both are tape & reel surface mount)
• Supply chain logistics and procurement channels
• Cost considerations within your procurement framework

Both parts meet identical electrical specifications, thermal operating ranges, and regulatory compliance requirements. No functional or performance differentiation exists between these substitutes based on provided parameters.

Frequently Asked Questions (FAQ)
