MP3320AGG-P Equivalent & Substitute Parts

Part Overview

The MP3320AGG-P is a 4-channel LED driver IC manufactured by Monolithic Power Systems Inc., designed for RGB LED applications. It integrates a switched capacitor (charge pump) topology DC-DC regulator with support for analog, I2C, and PWM dimming control. The device operates from 1.8V to 5.5V supply voltage and delivers 51mA per output channel. Currently in active production status with 1,041 units in stock, this component is widely used in general-purpose LED lighting applications requiring compact surface-mount solutions.

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when supply chain constraints occur, or when design flexibility is required for procurement optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP3320AGG-P is determined by strict parametric equivalence across the following critical specifications:

Electrical Parameters:

• Supply voltage range: 1.8V to 5.5V
• Output voltage: 5.5V
• Output current per channel: 51mA
• Switching frequency: 1MHz
• Dimming control methods: Analog, I2C, PWM

Mechanical Parameters:

• Package type: 14-VFQFN (14-QFN 2x2mm)
• Mounting type: Surface Mount
• Number of output channels: 4

Compliance & Environmental:

• Operating temperature range: -40°C to 125°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)
• REACH unaffected status

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. Deviation in any critical parameter disqualifies a part from this substitution group.

Parameter Comparison

Engineering Selection Recommendations

Both MP3320AGG-P and MP3320AGG-Z are parametrically identical 4-channel LED driver ICs from Monolithic Power Systems Inc. The parts differ only in packaging designation suffix, which reflects manufacturing or distribution variants rather than functional differences.

Selection Criteria:

The MP3320AGG-P is the primary part number with higher current inventory (1,041 units). Selection between MP3320AGG-P and MP3320AGG-Z should be based on:

• Procurement lead time requirements and supplier availability
• Current inventory levels at distribution partners
• Design documentation and qualification history with the specific part number
• Supply chain continuity planning

Both parts maintain active production status, ROHS3 compliance, and unlimited moisture sensitivity rating (MSL 1), ensuring long-term availability and regulatory compliance for production designs.

Frequently Asked Questions (FAQ)

Q: Can MP3320AGG-Z be used as a direct replacement for MP3320AGG-P in production?

A: Yes. Both parts are parametrically equivalent across all electrical, mechanical, and environmental specifications. They share identical supply voltage ranges (1.8V–5.5V), output current (51mA per channel), switching frequency (1MHz), dimming control methods (Analog, I2C, PWM), and package type (14-QFN 2x2mm). No circuit modifications are required.

Q: What is the difference between MP3320AGG-P and MP3320AGG-Z?

A: The suffix designation (P vs. Z) indicates a packaging or distribution variant. Both parts are manufactured by Monolithic Power Systems Inc. and are functionally identical. The difference does not affect electrical performance, pin configuration, or thermal characteristics.

Q: Are there any compatibility concerns with PCB layout or thermal management?

A: No. Both parts use the identical 14-VFQFN package (14-QFN 2x2mm) with the same pin configuration, footprint, and thermal properties. Existing PCB designs require no modification for substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both MP3320AGG-P and MP3320AGG-Z are ROHS3 compliant, REACH unaffected, and rated for -40°C to 125°C operating temperature. They carry identical MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current supplier availability, inventory levels, and procurement lead times. Both parts maintain active production status and equivalent long-term availability.

Q: Can these parts be mixed in the same production batch?

A: Yes. Since both parts are parametrically identical and use the same package, they can be used interchangeably within the same design and production run without functional impact.
