MP3324GRE-Z LED Driver IC - Equivalent & Substitute Parts

Part Overview

The MP3324GRE-Z is an 8-channel linear LED driver IC manufactured by Monolithic Power Systems Inc., designed for general-purpose LED applications requiring independent channel control. This active product delivers 100mA per channel with dual dimming capability (Analog and PWM), operating across a 4V to 16V supply range. The device is housed in a 24-QFN (4x4) surface mount package with wettable flanks, suitable for automated assembly processes. Substitute parts are identified when inventory constraints, supply chain disruptions, or procurement requirements necessitate alternative sourcing while maintaining full electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP3324GRE-Z is determined by strict parametric matching across the following critical criteria:

Electrical Parameters:

• 8-channel output configuration
• 100mA per-channel current rating
• 4V to 16V supply voltage range
• Analog and PWM dimming capability
• Linear topology with internal switching

Mechanical Parameters:

• 24-QFN (4x4) package footprint
• Surface mount with wettable flank construction
• Identical pin configuration and signal routing

Compliance & Environmental:

• ROHS3 compliance
• MSL Level 1 rating
• Operating temperature range -40°C to 125°C

Parts meeting all parameters above are classified as parametric equivalents and direct substitutes. The MP3324GRE-P qualifies as a full substitute based on identical electrical specifications, package geometry, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (MP3324GRE-Z): The MP3324GRE-Z is the specified part number with current inventory of 5,672 units. This part maintains active product status with full ROHS3 compliance and MSL Level 1 rating, indicating no moisture sensitivity constraints during storage and handling. Selection of this part number is appropriate for standard procurement cycles.

Substitute Selection (MP3324GRE-P): The MP3324GRE-P is a parametric equivalent with identical electrical and mechanical specifications. With 1,522 units in inventory, this part serves as a direct substitute when MP3324GRE-Z availability is constrained. Both parts share identical compliance certifications (ROHS3, REACH Unaffected, EAR99 classification) and environmental ratings. The packaging designation difference (TR notation) reflects tape and reel format consistency across both variants. No design modifications, PCB layout changes, or firmware adjustments are required when substituting between these parts.

Compliance Verification: Both parts maintain ROHS3 compliance and REACH unaffected status, suitable for applications requiring regulatory adherence in consumer electronics, industrial lighting, and automotive LED driver applications.

Frequently Asked Questions (FAQ)

Q: Can MP3324GRE-P be used as a direct replacement for MP3324GRE-Z in production?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (8 channels, 100mA per channel, 4V-16V supply), identical package geometry (24-QFN 4x4), and identical compliance ratings (ROHS3, MSL Level 1). No circuit modifications are required.

Q: Are there differences in pin configuration between MP3324GRE-Z and MP3324GRE-P?

A: No. Both parts use the 24-QFN (4x4) package with wettable flank construction. Pin assignments, signal routing, and mechanical footprints are identical.

Q: What does the packaging designation "Tape & Reel (TR)" indicate?

A: Tape & Reel packaging indicates the parts are supplied on continuous carrier tape wound on reels, optimized for automated pick-and-place assembly. Both MP3324GRE-Z and MP3324GRE-P are supplied in this format.

Q: Are both parts suitable for the full operating temperature range?

A: Yes. Both MP3324GRE-Z and MP3324GRE-P operate across -40°C to 125°C junction temperature, meeting industrial and extended temperature requirements.

Q: What is the significance of MSL Level 1 rating?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture bake-out requirements. Both parts can be stored indefinitely under standard conditions without special humidity controls.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. Identical electrical parameters, package footprints, and pin configurations enable direct substitution without design changes, PCB layout modifications, or firmware updates.

Q: Are there supply chain or availability differences between the two parts?

A: Current inventory shows MP3324GRE-Z at 5,672 units and MP3324GRE-P at 1,522 units. Selection should be based on procurement lead times and inventory availability at the time of ordering.
