Key Parameters

Substitute Part Grouping Explanation

The MP26124GR-Z qualifies as a parametric equivalent to the MP26124GR-P based on the following matching criteria:

• Identical battery chemistry (Lithium Ion) and cell count (4 cells)
• Matching maximum charge current (2A) and battery pack voltage (16.8V)
• Identical supply voltage specification (24V maximum)
• Same operating temperature rating (125°C TJ)
• Identical package type (16-VQFN Exposed Pad) and mounting method (Surface Mount)
• Matching programmable features (Current, Timer) and fault protection (Over Current, Over Temperature)
• Identical regulatory compliance (ROHS3, REACH Unaffected, EAR99)
• Same moisture sensitivity level (MSL 1 - Unlimited)

Both parts share the same base product number (MP26124) and are manufactured by the same supplier, confirming functional and mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both MP26124GR-P and MP26124GR-Z are active products with identical electrical and mechanical specifications. Selection between these parts should be based on availability and supply chain requirements. The MP26124GR-Z currently maintains higher inventory levels (35,100 pcs vs. 1,479 pcs), which may provide supply continuity advantages. Both parts meet ROHS3 compliance and REACH requirements, ensuring regulatory compatibility in target applications. No performance differentiation exists between these variants based on provided specifications.

Frequently Asked Questions (FAQ)

Q: Are MP26124GR-P and MP26124GR-Z pin-for-pin compatible? A: Yes. Both parts use identical 16-VQFN Exposed Pad packaging with Surface Mount configuration, ensuring direct PCB compatibility without layout modifications.

Q: Can I substitute MP26124GR-Z for MP26124GR-P in existing designs? A: Yes. The parts are parametric equivalents with matching electrical specifications, including charge current (2A), battery voltage (16.8V), supply voltage (24V), and operating temperature (125°C). No design changes are required.

Q: Do both parts support the same programmable features? A: Yes. Both MP26124GR-P and MP26124GR-Z provide identical programmable current and timer functionality with matching over-current and over-temperature fault protection.

Q: Are there any compliance differences between these parts? A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What is the primary difference between these two part numbers? A: The parts are functionally identical. The difference is limited to packaging designation (suffix -P vs. -Z) and current inventory availability.
