MP26053DQ-LF-P Equivalent & Substitute Parts

Part Overview

The MP26053DQ-LF-P is an active lithium ion/polymer battery charger IC in a 10-QFN (3x3) surface mount package manufactured by Monolithic Power Systems Inc. This single-cell charger integrates constant-current/constant-voltage charging with programmable timer functionality and over-voltage fault protection. The part is ROHS3 compliant and currently in active production status with 850 units in stock.

Substitute parts are identified when electrical parameters, mechanical specifications, and compliance certifications remain equivalent across the product line, enabling direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP26053DQ-LF-P is determined by equivalence across the following critical parameters:

• Battery chemistry (Lithium Ion/Polymer)
• Single-cell configuration
• Maximum charge current (1A)
• Battery pack voltage (4.2V)
• Maximum supply voltage (6.5V)
• Operating temperature range (-40°C ~ 85°C)
• Package type (10-VFDFN Exposed Pad)
• Surface mount capability
• ROHS3 compliance status
• MSL rating (1 - Unlimited)

All identified substitute parts maintain identical electrical specifications and mechanical compatibility. Packaging format (Tape & Reel vs. Cut Tape) represents a logistics variation only and does not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status with ROHS3 compliance and REACH unaffected certification. Selection between MP26053DQ-LF-P, MP2605DQ-LF-P, MP2605DQ-LF-Z, and MP26121DQ-LF-P is determined by packaging format availability and inventory requirements.

For applications requiring Tape & Reel packaging, MP26053DQ-LF-P, MP2605DQ-LF-P, and MP26121DQ-LF-P are functionally equivalent. For applications where Cut Tape packaging is acceptable, MP2605DQ-LF-Z offers significantly higher inventory availability (25400 units) compared to other variants.

All parts share identical electrical specifications, thermal operating range, and mechanical footprint compatibility, enabling direct PCB-level substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can MP2605DQ-LF-Z replace MP26053DQ-LF-P in production?

A: Yes. Both parts are electrically and mechanically equivalent. The difference is packaging format: MP2605DQ-LF-Z is supplied in Cut Tape (CT) while MP26053DQ-LF-P is supplied in Tape & Reel (TR). PCB assembly compatibility is identical.

Q: Are there electrical differences between the base product numbers MP26053, MP2605, and MP26121?

A: No. All variants specified here maintain identical electrical parameters: 1A maximum charge current, 4.2V battery pack voltage, 6.5V maximum supply voltage, and -40°C to 85°C operating temperature range.

Q: What does MSL 1 (Unlimited) mean for these parts?

A: MSL 1 indicates the lowest moisture sensitivity level. These parts have unlimited shelf life under standard storage conditions and do not require special moisture control during handling or storage.

Q: Can I use MP26121DQ-LF-P as a direct substitute for MP26053DQ-LF-P?

A: Yes. Both parts are ROHS3 compliant, share identical package specifications (10-VFDFN Exposed Pad), and maintain equivalent electrical performance across all specified parameters.

Q: Which substitute part has the best inventory availability?

A: MP2605DQ-LF-Z has the highest inventory level at 25400 units. If packaging format (Cut Tape) is compatible with your assembly process, this variant offers the best supply continuity.
