Substitute Part Grouping Explanation

The MP26101DR-LF-P qualifies as a parametric equivalent to the MP26101DR-LF-Z based on identical electrical and mechanical specifications. Substitution is valid when the following criteria are met:

• Battery chemistry and cell count remain constant (Lithium Ion, 1 ~ 2 cells)
• Maximum charge current specification is identical (2A)
• Battery pack voltage rating matches (8.2V)
• Supply voltage maximum is unchanged (24V)
• Operating temperature range is equivalent (125°C TJ)
• Package and case designation are identical (16-VQFN Exposed Pad, 16-QFN 4x4)
• Mounting type remains Surface Mount
• Compliance certifications are equivalent (ROHS3, MSL 1)
• Base product number is identical (MP26101)

Both parts share the same functional features: programmable constant-current charging, timer-based programmable features, and dual fault protection (Over Current, Over Temperature).

Parameter Comparison

Engineering Selection Recommendations

Both MP26101DR-LF-Z and MP26101DR-LF-P are active production parts with identical electrical performance and mechanical compatibility. Selection between these variants should be based on inventory availability and supply chain considerations. The MP26101DR-LF-Z currently maintains 775 units in stock, while the MP26101DR-LF-P has 961 units available. Both parts meet ROHS3 compliance requirements and carry MSL 1 moisture sensitivity classification, indicating no special storage or handling restrictions. The identical base product number (MP26101) and package designation (16-QFN 4x4) confirm direct interchangeability in PCB layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can MP26101DR-LF-P be used as a direct replacement for MP26101DR-LF-Z in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, package dimensions, and pin configurations. No design modifications are required for substitution.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is valid when battery chemistry (Lithium Ion), cell count (1 ~ 2), maximum charge current (2A), battery pack voltage (8.2V), supply voltage maximum (24V), operating temperature (125°C TJ), and package type (16-VQFN Exposed Pad, 16-QFN 4x4) remain identical across parts.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical ROHS3 compliance status, MSL 1 moisture sensitivity classification, and REACH unaffected designation. Regulatory and environmental compliance is equivalent.

Q: What is the significance of the packaging designation difference (TR vs. TR)?

A: Both parts are supplied in Tape & Reel (TR) packaging format, which is standard for high-volume surface mount assembly. No functional or compatibility differences exist.

Q: Can these parts be mixed in the same production batch?

A: Yes. Since both parts are parametric equivalents with identical electrical and mechanical specifications, they can be used interchangeably within the same assembly process without affecting circuit performance or reliability.
