MP3364GR-Z Equivalent & Substitute Parts

Part Overview

The MP3364GR-Z is an LED Driver IC manufactured by Monolithic Power Systems Inc., classified as a Power Management (PMIC) component. This device functions as a 4-output DC-DC regulator with step-up (boost) topology, designed for LED backlight applications. The IC integrates PWM dimming control with a 150mA output current per channel and operates across a wide supply voltage range of 3.5V to 36V.

The MP3364GR-Z maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when inventory constraints, supply chain disruptions, or procurement requirements necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the MP3364GR-Z is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Electrical Parameters (Must Match Exactly):

• DC-DC regulator topology: Step-Up (Boost)
• Number of outputs: 4
• Supply voltage range: 3.5V to 36V (minimum and maximum)
• Output voltage range: 0.6V to 36V
• Output current per channel: 150mA
• Operating frequency: 400kHz to 2.2MHz
• Dimming capability: Analog and PWM

Mechanical Parameters (Must Match Exactly):

• Package type: 24-VFQFN Exposed Pad
• Device package: 24-QFN (4x4)
• Mounting type: Surface Mount

Compliance & Status (Must Match):

• Manufacturer: Monolithic Power Systems Inc.
• Product Status: Active
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The MP3364GR-Z and its substitute share the same base product number (MP3364), differing only in packaging designation suffix. Both parts are sourced from the same manufacturer and maintain identical functional specifications.

Parameter Comparison

Engineering Selection Recommendations

The MP3364GR-P is a direct parametric equivalent to the MP3364GR-Z. Both parts are manufactured by Monolithic Power Systems Inc. and maintain identical electrical specifications, mechanical packaging, and compliance certifications.

Selection Basis:

Both parts are Active status products with ROHS3 compliance and REACH unaffected designation, ensuring regulatory compliance for industrial and commercial applications. The MSL 1 rating (unlimited moisture sensitivity) indicates both parts are suitable for standard storage and handling conditions without special moisture control requirements.

The substitution is valid for any application requiring a 4-output LED driver IC with step-up boost topology, 150mA per-channel output current, and PWM/analog dimming control across the 3.5V to 36V supply range. The 24-QFN (4x4) surface mount package is identical between both parts, ensuring PCB layout compatibility without design modification.

Selection between MP3364GR-Z and MP3364GR-P is determined by availability and procurement requirements. Both parts are functionally interchangeable with no performance differentiation.
