MP2602DQ-LF-Z Equivalent & Substitute Parts

Part Overview

The MP2602DQ-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 over-current, over-temperature, and over-voltage conditions. The device is housed in a 10-QFN (3x3) package with exposed pad and is ROHS3 compliant. Alternative part numbers become necessary when the Cut Tape packaging format is unavailable or when supply chain constraints require sourcing from alternative packaging configurations while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution for the MP2602DQ-LF-Z is determined by strict equivalence across the following critical parameters:

• Battery Chemistry: Lithium Ion
• Number of Cells: 1
• Charge Current - Max: 1A
• Battery Pack Voltage: 4.2V
• Voltage - Supply (Max): 5.5V
• Operating Temperature Range: -40°C ~ 85°C (TA)
• Package / Case: 10-VFDFN Exposed Pad
• Supplier Device Package: 10-QFN (3x3)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

The substitute parts MP26023DQ-LF-P and MP26023DQ-LF-Z meet all electrical and mechanical requirements for direct substitution. The primary difference is packaging format: MP2602DQ-LF-Z is supplied in Cut Tape (CT) & Digi-Reel® format, while MP26023DQ-LF-P is supplied in Tape & Reel (TR) format, and MP26023DQ-LF-Z is also supplied in Tape & Reel (TR) format. Both substitute parts maintain identical functional specifications and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—MP2602DQ-LF-Z, MP26023DQ-LF-P, and MP26023DQ-LF-Z—are Active products from Monolithic Power Systems Inc. with identical electrical specifications and compliance certifications. Selection between these parts should be based on packaging availability and supply chain requirements:

• MP2602DQ-LF-Z: Cut Tape (CT) & Digi-Reel® packaging, 56,776 pcs in stock
• MP26023DQ-LF-P: Tape & Reel (TR) packaging, 1,038 pcs in stock
• MP26023DQ-LF-Z: Tape & Reel (TR) packaging, 55,300 pcs in stock

All parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating. Electrical performance, thermal characteristics, and fault protection features are identical across all three part numbers.

Frequently Asked Questions (FAQ)

Q: Can MP26023DQ-LF-P and MP26023DQ-LF-Z be used interchangeably with MP2602DQ-LF-Z?

A: Yes. All three parts are electrically and mechanically equivalent. They share identical specifications for charging current (1A max), battery pack voltage (4.2V), supply voltage (5.5V max), operating temperature range (-40°C ~ 85°C), package type (10-VFDFN Exposed Pad), and compliance certifications. The only difference is packaging format: Cut Tape versus Tape & Reel.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) & Digi-Reel® is a smaller quantity packaging format suitable for lower-volume applications or manual assembly. Tape & Reel (TR) is standard for automated pick-and-place assembly and higher-volume production. Both formats contain the same component in the same 10-QFN (3x3) package.

Q: Are there any electrical performance differences between these part numbers?

A: No. All three parts deliver identical electrical performance: 1A maximum charging current, 4.2V battery pack voltage, 5.5V maximum supply voltage, and -40°C ~ 85°C operating temperature range. Fault protection (over-current, over-temperature, over-voltage) is identical across all variants.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. MP2602DQ-LF-Z, MP26023DQ-LF-P, and MP26023DQ-LF-Z are all ROHS3 compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which part should I select for new designs?

A: Selection depends on your assembly process and supply chain strategy. For automated assembly, Tape & Reel (TR) formats (MP26023DQ-LF-P or MP26023DQ-LF-Z) are standard. For manual assembly or lower volumes, Cut Tape format (MP2602DQ-LF-Z) may be appropriate. All three are Active products suitable for new designs.
