MP4031GS-P LED Driver IC - Equivalent & Substitute Parts

Part Overview

The MP4031GS-P is an AC DC offline switcher LED driver IC manufactured by Monolithic Power Systems Inc. This device integrates a flyback topology converter with analog and TRIAC dimming capabilities, designed for single-output lighting applications in commercial and industrial environments. The part operates across an input voltage range of 11V to 27V and is housed in an 8-SOIC surface mount package.

The MP4031GS-P maintains Active product status and is ROHS3 compliant. Identifying equivalent substitute parts is necessary for supply chain continuity, inventory optimization, and design flexibility when the primary part number becomes unavailable or when alternative packaging configurations are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP4031GS-P is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Device Type: AC DC Offline Switcher
• Topology: Flyback
• Number of Outputs: 1
• Voltage Supply Range: 11V to 27V minimum and maximum
• Dimming Capability: Analog and TRIAC support
• Package Type: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C to 125°C (TJ)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 2 (1 Year)

The MP4031GS-Z qualifies as a parametric equivalent substitute. Both parts share identical electrical specifications, thermal ratings, and package dimensions. The primary distinction between these parts is the packaging configuration: MP4031GS-P is supplied in standard packaging, while MP4031GS-Z is supplied in Tape & Reel (TR) format. This difference accommodates different procurement and assembly workflows without affecting functional performance or compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the MP4031GS-P and MP4031GS-Z are Active products manufactured by Monolithic Power Systems and maintain full ROHS3 compliance with identical Moisture Sensitivity Level ratings. Selection between these parts should be based on procurement and assembly requirements:

MP4031GS-P is appropriate for applications requiring standard packaging configurations and lower-volume procurement workflows.

MP4031GS-Z is appropriate for high-volume manufacturing environments and automated assembly processes that utilize Tape & Reel packaging. The TR format provides improved handling efficiency and reduced component damage during pick-and-place operations.

Both parts deliver identical electrical performance, thermal characteristics, and functional capabilities in commercial and industrial lighting applications. No performance degradation or functional limitation occurs when substituting between these part numbers within the same design.

Frequently Asked Questions (FAQ)

Q: Can MP4031GS-Z be used as a direct replacement for MP4031GS-P in production?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, thermal ratings, package dimensions, and compliance certifications. The only difference is packaging format (standard versus Tape & Reel). Direct substitution is functionally valid.

Q: What is the difference between MP4031GS-P and MP4031GS-Z packaging?

A: MP4031GS-P uses standard packaging suitable for manual handling and lower-volume orders. MP4031GS-Z uses Tape & Reel (TR) packaging, which is optimized for automated pick-and-place assembly equipment and high-volume manufacturing.

Q: Are there any electrical performance differences between these part numbers?

A: No. Both parts operate identically across all electrical parameters: input voltage range (11V to 27V), output configuration (single output), dimming capability (analog and TRIAC), and operating temperature range (-40°C to 125°C).

Q: Do both parts meet the same compliance standards?

A: Yes. Both MP4031GS-P and MP4031GS-Z are ROHS3 compliant, REACH unaffected, and carry identical Moisture Sensitivity Level ratings (MSL 2, 1 Year).

Q: Which part should be selected for a new design?

A: Selection depends on manufacturing volume and assembly infrastructure. For high-volume automated assembly, MP4031GS-Z (Tape & Reel) is preferred. For lower volumes or manual assembly, MP4031GS-P is appropriate. Both deliver identical performance.

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

A: Yes. Since both parts are parametric equivalents with identical electrical and thermal characteristics, they can be used interchangeably within the same design and production environment without functional impact.
