MP2633GR-P Equivalent & Substitute Parts

Part Overview

The MP2633GR-P is a single-cell lithium ion/polymer battery charger IC manufactured by Monolithic Power Systems Inc. in a 24-QFN (4x4) surface mount package. This active product integrates programmable charging current control, timer functionality, and fault protection for over-temperature and short-circuit conditions. The part is designed for applications requiring constant-current programmable charging with a maximum charge current of 1.5A and battery pack voltage of 4.2V. Finding equivalent substitute parts is necessary to ensure supply chain flexibility, manage inventory optimization, and maintain design continuity when primary part availability is constrained.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MP2633GR-P is determined by strict equivalence across the following critical parameters:

• Battery chemistry and cell count (Lithium Ion/Polymer, 1 cell)
• Maximum charge current (1.5A)
• Battery pack voltage (4.2V)
• Maximum supply voltage (6V)
• Operating temperature range (-40°C ~ 125°C)
• Package type (24-VFQFN Exposed Pad)
• Mounting technology (Surface Mount)
• Functional features (Constant-current programmable charging, timer, over-temperature and short-circuit protection)

The MP2633GR-Z qualifies as a parametric equivalent substitute because it matches all critical electrical and mechanical specifications. Both parts share the same base product number (MP2633), manufacturer, and functional feature set. The difference between these parts is limited to packaging designation (tape reel variant), which does not affect electrical performance or board-level compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both MP2633GR-P and MP2633GR-Z are active products from Monolithic Power Systems Inc. with identical electrical specifications and compliance certifications. Selection between these parts should be based on:

• Supply chain availability and lead time requirements
• Packaging format preference (cut tape vs. reel configuration)
• Inventory management and procurement strategy
• Current stock levels and pricing

Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating, ensuring compatibility with standard manufacturing processes and long-term reliability requirements. No functional or performance differences exist between these substitutes.

Frequently Asked Questions (FAQ)

Q: Can MP2633GR-Z be used as a direct replacement for MP2633GR-P on the same PCB?

A: Yes. Both parts are electrically and mechanically identical, with the same 24-VFQFN Exposed Pad package, pin configuration, and functional specifications. No design changes are required.

Q: What is the difference between MP2633GR-P and MP2633GR-Z?

A: The primary difference is packaging format. MP2633GR-P is supplied in cut tape (CT), while MP2633GR-Z is supplied in reel format. All electrical parameters, performance characteristics, and compliance certifications are identical.

Q: Are there any temperature or voltage rating differences between these parts?

A: No. Both parts operate across the same temperature range (-40°C ~ 125°C junction temperature) and support identical supply voltage (6V maximum) and battery voltage (4.2V) specifications.

Q: Do both parts support the same charging current and battery chemistry?

A: Yes. Both MP2633GR-P and MP2633GR-Z support 1.5A maximum charge current and are designed for single-cell lithium ion/polymer battery applications.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical ROHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity rating.

Q: Which part should I select for new designs?

A: Selection should be based on supply availability, packaging preference, and procurement requirements. Both parts are active products with no planned obsolescence. Electrical performance and reliability are equivalent.
