Key Parameters

Substitute Part Grouping Explanation

The MP26057DQ-LF-Z qualifies as a parametric equivalent to the MP26057DQ-LF-P based on strict alignment across all critical electrical and mechanical parameters. Both parts share identical specifications for battery chemistry (Lithium Ion/Polymer), single-cell configuration, maximum charge current (1A), battery pack voltage (4.2V), maximum supply voltage (5.5V), USB interface, operating temperature range (-40°C ~ 85°C), package type (10-VFDFN Exposed Pad), and mounting method (Surface Mount). Both maintain ROHS3 compliance, MSL Level 1 rating, and active product status. The substitution is valid because the parts are functionally and mechanically interchangeable within the same design without modification to PCB layout, firmware, or system integration.

Parameter Comparison

Engineering Selection Recommendations

Both the MP26057DQ-LF-P and MP26057DQ-LF-Z are active products with identical compliance certifications (ROHS3, REACH Unaffected, EAR99 ECCN classification). Selection between these parts should be based on supply chain availability and inventory status. The MP26057DQ-LF-P currently maintains 1705 units in stock, while the MP26057DQ-LF-Z has 5400 units available. For applications requiring immediate procurement or high-volume production, the MP26057DQ-LF-Z offers superior inventory availability without compromising electrical or mechanical compatibility. Both parts are suitable for direct substitution in existing designs without PCB revision or system re-qualification.

Frequently Asked Questions (FAQ)

Q: Can MP26057DQ-LF-Z be used as a direct replacement for MP26057DQ-LF-P in production?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including package type (10-VFDFN Exposed Pad), pin configuration, and functional characteristics. No design changes are required.

Q: Are there differences in charging performance between these two part numbers?

A: No. Both parts deliver identical charging specifications: 1A maximum charge current, 4.2V battery pack voltage, 5.5V maximum supply voltage, and USB interface operation.

Q: Do both parts support the same operating temperature range?

A: Yes. Both the MP26057DQ-LF-P and MP26057DQ-LF-Z operate across -40°C to 85°C ambient temperature range.

Q: What is the significance of the different suffixes (-LF-P vs. -LF-Z)?

A: The suffix designates the tape and reel packaging configuration. Both are surface mount compatible with identical electrical and mechanical specifications. The difference is packaging format only, not functional performance.

Q: Are both parts RoHS compliant?

A: Yes. Both the MP26057DQ-LF-P and MP26057DQ-LF-Z are ROHS3 compliant with MSL Level 1 moisture sensitivity rating.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should prioritize current inventory availability and supply chain lead times. Both maintain active product status with identical long-term support from Monolithic Power Systems Inc.
