MP26023DQ-LF-Z Equivalent & Substitute Parts

Part Overview

The MP26023DQ-LF-Z is a lithium-ion battery charger IC manufactured by Monolithic Power Systems Inc., designed for single-cell battery charging applications. This Power Management IC operates with a maximum supply voltage of 5.5V and delivers a programmable charging current up to 1A, with integrated fault protection for overcurrent, overtemperature, and overvoltage conditions. The device is housed in a 10-QFN (3x3) package with exposed pad and is actively produced. Alternative part numbers may be required due to packaging format availability, inventory constraints, or supply chain considerations.

Substitute Part Grouping Explanation

Substitution eligibility for the MP26023DQ-LF-Z is determined by strict equivalence across the following critical parameters: battery chemistry (Lithium Ion), single-cell configuration, maximum charging current (1A), battery pack voltage (4.2V), maximum supply voltage (5.5V), operating temperature range (-40°C ~ 85°C), package type (10-QFN 3x3 with exposed pad), and fault protection features (overcurrent, overtemperature, overvoltage).

The substitute parts identified—MP26023DQ-LF-P and MP2602DQ-LF-Z—maintain identical electrical specifications and mechanical compatibility. The primary distinction between these parts lies in packaging format: MP26023DQ-LF-Z and MP26023DQ-LF-P are supplied in Tape & Reel format, while MP2602DQ-LF-Z is supplied in Cut Tape & Digi-Reel format. All three parts are manufactured by Monolithic Power Systems Inc., carry Active product status, and comply with ROHS3 and REACH requirements.

Parameter Comparison

Engineering Selection Recommendations

All three parts—MP26023DQ-LF-Z, MP26023DQ-LF-P, and MP2602DQ-LF-Z—are functionally equivalent and suitable for direct substitution in single-cell lithium-ion battery charging applications. Selection between these parts should be based on packaging format requirements and supply availability.

MP26023DQ-LF-Z and MP26023DQ-LF-P are supplied in standard Tape & Reel format, suitable for high-volume automated assembly processes. MP2602DQ-LF-Z is supplied in Cut Tape & Digi-Reel format, appropriate for lower-volume applications or manual assembly workflows.

All parts maintain Active product status, ensuring long-term availability and manufacturing support. Compliance certifications—ROHS3, REACH Unaffected, and MSL Level 1—are identical across all three options, confirming regulatory and environmental suitability for equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can MP26023DQ-LF-P be used as a direct replacement for MP26023DQ-LF-Z?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: MP26023DQ-LF-Z uses Tape & Reel, while MP26023DQ-LF-P also uses Tape & Reel. Both are suitable for automated assembly.

Q: What is the difference between MP26023DQ-LF-Z and MP2602DQ-LF-Z?

A: Electrical and mechanical specifications are identical. The primary difference is packaging format: MP26023DQ-LF-Z is supplied in Tape & Reel, while MP2602DQ-LF-Z is supplied in Cut Tape & Digi-Reel format. Both maintain the same 10-QFN (3x3) package footprint.

Q: Are all three parts suitable for the same PCB layout?

A: Yes. All three parts use the identical 10-VFDFN Exposed Pad package with 10-QFN (3x3) footprint. PCB layout, schematic, and thermal design remain unchanged across all substitutes.

Q: Do packaging format differences affect electrical performance?

A: No. Packaging format (Tape & Reel versus Cut Tape & Digi-Reel) affects only supply chain logistics and assembly handling. Electrical performance, thermal characteristics, and reliability are identical.

Q: Are all parts compliant with current environmental regulations?

A: Yes. All three parts are ROHS3 Compliant, REACH Unaffected, and carry MSL Level 1 (Unlimited moisture sensitivity). Regulatory status is equivalent across all options.

Q: Which part should be selected for high-volume production?

A: MP26023DQ-LF-Z or MP26023DQ-LF-P are recommended for high-volume automated assembly due to standard Tape & Reel packaging. MP2602DQ-LF-Z is suitable for lower-volume or manual assembly workflows.
