Key Parameters

Substitute Part Grouping Explanation

The MP26101DR-LF-Z qualifies as a parametric equivalent to the MP26101DR-LF-P based on identical electrical and mechanical specifications. Both parts share the same base product number (MP26101), manufacturer (Monolithic Power Systems), and all critical functional parameters including battery chemistry, cell count, maximum charge current, supply voltage rating, operating temperature, and package configuration. The substitution is valid because both devices meet the same electrical performance requirements and physical form factor constraints. The difference between these part numbers reflects manufacturing lot designation or packaging variant coding within the same product family, not functional differentiation.

Parameter Comparison

Engineering Selection Recommendations

Both MP26101DR-LF-P and MP26101DR-LF-Z are active products with identical compliance certifications (ROHS3 Compliant, REACH Unaffected, EAR99 classification). Selection between these parts should be based on procurement availability and inventory status. The MP26101DR-LF-P currently maintains 961 pieces in stock, while the MP26101DR-LF-Z maintains 775 pieces. Both parts carry MSL Level 1 (Unlimited) moisture sensitivity, eliminating moisture-related handling constraints. No functional or reliability differentiation exists between these devices for lithium-ion battery charging applications requiring 1-2 cell configurations with 2A maximum charge current and 24V maximum supply voltage.

Frequently Asked Questions (FAQ)

Q: Can MP26101DR-LF-Z be used as a direct replacement for MP26101DR-LF-P in production? A: Yes. Both parts are functionally identical across all electrical parameters, thermal ratings, and package specifications. No circuit redesign or PCB layout modification is required.

Q: Are there any differences in pin configuration or pinout between these parts? A: No. Both devices use the identical 16-VQFN (4x4) Exposed Pad package with matching pin assignments and functionality.

Q: Do these parts require different handling or storage procedures? A: No. Both parts carry MSL Level 1 (Unlimited) moisture sensitivity rating, requiring no special moisture control measures during storage or handling.

Q: What is the basis for substitution between MP26101DR-LF-P and MP26101DR-LF-Z? A: Substitution is based on identical battery chemistry (Lithium Ion), cell count (1-2), maximum charge current (2A), supply voltage rating (24V maximum), operating temperature (125°C TJ), package type (16-VQFN Exposed Pad), and compliance certifications (ROHS3, REACH Unaffected).

Q: Can these parts be mixed in the same production batch? A: Yes. Both parts meet identical specifications and certifications, allowing interchangeable use within the same assembly process.
