MP2611GL-Z Equivalent & Substitute Parts

Part Overview

The MP2611GL-Z is a single-cell lithium-ion battery charger IC manufactured by Monolithic Power Systems Inc., housed in a 14-QFN (3x4) package with exposed pad. This active product integrates constant-current/constant-voltage charging control with programmable timer functionality and comprehensive fault protection including over-current and over-temperature monitoring. The charger operates from a 6V maximum supply and delivers up to 2A charging current to 4.2V battery packs via USB interface. Finding equivalent substitute parts is necessary to ensure supply chain continuity, optimize inventory management, and maintain design flexibility across manufacturing batches.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP2611GL-Z is determined by strict equivalence across the following critical parameters:

• Battery chemistry and cell count (Lithium Ion, 1 cell)
• Maximum charging current (2A)
• Target battery voltage (4.2V)
• Maximum supply voltage (6V)
• Interface type (USB)
• Package form factor (14-QFN 3x4 with exposed pad)
• Operating temperature range (-40°C ~ 125°C)
• Mounting technology (Surface Mount)
• Regulatory compliance (ROHS3, REACH Unaffected)

The MP2611GL-P qualifies as a parametric equivalent because it maintains identical electrical specifications, thermal operating range, package geometry, and compliance certifications as the MP2611GL-Z. Both parts share the same base product number (MP2611) and are manufactured by the same supplier.

Parameter Comparison

Engineering Selection Recommendations

Both MP2611GL-Z and MP2611GL-P are active products with identical electrical, thermal, and mechanical specifications. Selection between these parts should be based on:

• Availability and lead time from your supply chain
• Packaging format preference (both use Tape & Reel)
• Current inventory levels (MP2611GL-Z: 5373 pcs; MP2611GL-P: 727 pcs)
• Compliance requirements (both meet ROHS3 and REACH standards)

No functional or performance differences exist between these parts. PCB layout, schematic integration, and firmware requirements remain unchanged when substituting between MP2611GL-Z and MP2611GL-P.

Frequently Asked Questions (FAQ)

Q: Can MP2611GL-P be used as a direct replacement for MP2611GL-Z in production?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. No design changes are required.

Q: Are there differences in the 14-QFN package between these parts?

A: No. Both use the 14-VFDFN Exposed Pad package with 3x4mm dimensions. PCB footprints are identical.

Q: Do these parts have different thermal characteristics?

A: No. Both operate across the same temperature range (-40°C ~ 125°C junction temperature) and share identical thermal specifications.

Q: What is the difference between the MP2611GL-Z and MP2611GL-P part numbers?

A: The suffix letters (-Z and -P) indicate different packaging or tape reel configurations from the manufacturer, but the electrical and functional specifications are identical.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both MP2611GL-Z and MP2611GL-P are ROHS3 compliant and REACH unaffected.

Q: Can I mix these parts in the same production batch?

A: Yes. Since both parts are parametrically equivalent with identical specifications, they can be used interchangeably without affecting circuit performance or reliability.
