MP26023DQ-LF-P Equivalent & Substitute Parts

Part Overview

The MP26023DQ-LF-P is a lithium-ion battery charger IC manufactured by Monolithic Power Systems Inc., designed for single-cell battery charging applications. This Power Management (PMIC) component operates as an active product with full RoHS3 compliance and REACH unaffected status. Alternative part numbers become necessary when the primary part number experiences supply constraints, packaging format changes, or when design flexibility permits equivalent functionality across the MP26023 and MP2602 series.

Substitute Part Grouping Explanation

Substitution eligibility for the MP26023DQ-LF-P is determined by strict equivalence across the following 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), Fault Protection capabilities (Over Current, Over Temperature, Over Voltage), Package / Case (10-VFDFN Exposed Pad), Mounting Type (Surface Mount), RoHS Status (ROHS3 Compliant), and MSL Rating (1).

The substitute parts MP26023DQ-LF-Z and MP2602DQ-LF-Z meet all electrical and mechanical parameter requirements for direct substitution. Differences exist only in packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) and inventory availability, which do not affect functional equivalence or PCB integration.

Engineering Selection Recommendations

All three part numbers—MP26023DQ-LF-P, MP26023DQ-LF-Z, and MP2602DQ-LF-Z—are active products with identical electrical specifications and mechanical compatibility. Selection between these parts should be based on packaging format availability and supply chain requirements rather than functional differences.

MP26023DQ-LF-P and MP26023DQ-LF-Z are both supplied in Tape & Reel format and share the same base product number (MP26023). MP2602DQ-LF-Z differs only in packaging format (Cut Tape & Digi-Reel®) and base product number (MP2602) while maintaining full electrical and mechanical equivalence.

All parts carry ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and consumer applications. MSL Rating 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: MP26023DQ-LF-P uses Tape & Reel while MP26023DQ-LF-Z also uses Tape & Reel. They are interchangeable for PCB assembly and functional performance.

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

A: The electrical specifications and package footprint are identical. MP2602DQ-LF-Z uses Cut Tape & Digi-Reel® packaging instead of Tape & Reel. The base product numbers differ (MP26023 versus MP2602), but this does not affect circuit functionality or PCB integration.

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

A: Yes. All three parts use the same 10-VFDFN Exposed Pad package with 10-QFN (3x3) footprint. PCB layout, solder pad dimensions, and component placement are identical across all three part numbers.

Q: What determines substitution eligibility for these lithium-ion charger ICs?

A: Substitution is based on matching 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), Fault Protection (Over Current, Over Temperature, Over Voltage), Package / Case (10-VFDFN Exposed Pad), and compliance certifications (ROHS3, REACH Unaffected).

Q: Do packaging format differences affect component selection?

A: Packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) affects supply chain logistics and handling but does not impact electrical performance or PCB assembly compatibility. Selection should be based on procurement requirements and assembly line equipment compatibility.

Q: Are all parts RoHS3 compliant?

A: Yes. MP26023DQ-LF-P, MP26023DQ-LF-Z, and MP2602DQ-LF-Z are all ROHS3 compliant with MSL Rating 1 (Unlimited), meeting regulatory requirements for industrial and consumer applications without moisture sensitivity constraints.
