MP6924AGS-Z Equivalent & Substitute Parts

Part Overview

The MP6924AGS-Z is a Power Supply Controller designed for secondary-side synchronous rectifier applications in isolated power supply topologies. This device operates as a fast turn-off, CCM/DCM compatible controller in an 8-SOIC surface mount package. The part carries a "Not For New Designs" product status, indicating it has been superseded in Monolithic Power Systems' product roadmap. This status necessitates identifying functionally equivalent alternatives for ongoing production support and new design considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP6924AGS-Z is determined by the following critical parameters:

• Functional Application: Secondary-side controller and synchronous rectifier operation
• Supply Voltage Range: 4.2V ~ 35V operating window
• Package Configuration: 8-SOIC surface mount form factor with 0.154" (3.90mm) width
• Electrical Compliance: RoHS3 and REACH compliance status
• Moisture Sensitivity: MSL 2 rating (1 Year)

The MP6924GS-Z qualifies as a direct substitute based on identical supply voltage specifications, matching 8-SOIC package geometry, equivalent functional application as a secondary-side synchronous rectifier controller, and aligned compliance certifications. Both parts share the same base product number (MP6924) and are manufactured by Monolithic Power Systems Inc.

Parameter Comparison

Engineering Selection Recommendations

Both the MP6924AGS-Z and MP6924GS-Z maintain identical compliance certifications (ROHS3 and REACH Unaffected) and equivalent moisture sensitivity ratings. The MP6924GS-Z is available in Cut Tape (CT) and Digi-Reel® packaging options, providing supply chain flexibility compared to the main part number. Both devices carry "Not For New Designs" status, indicating they represent legacy product lines within Monolithic Power Systems' portfolio.

Selection between these parts should be based on packaging availability and supply chain requirements rather than functional or electrical differences. The documented supply current specification of 16 mA for the MP6924GS-Z provides additional design reference data for power budget calculations in secondary-side controller applications.

Frequently Asked Questions (FAQ)

Q: Can MP6924GS-Z directly replace MP6924AGS-Z in existing designs?

A: Yes. Both parts operate within the identical 4.2V ~ 35V supply voltage range, utilize the same 8-SOIC package geometry, and perform equivalent secondary-side synchronous rectifier controller functions. Compliance certifications and moisture sensitivity ratings are identical.

Q: What is the significance of the "Not For New Designs" status?

A: This designation indicates the part has been superseded in the manufacturer's product roadmap. While suitable for production support of existing designs, these parts should not be selected for new development projects. Monolithic Power Systems may have released newer alternatives with enhanced features or improved specifications.

Q: Are there packaging differences between these substitute parts?

A: The MP6924AGS-Z packaging format is not specified in the provided data. The MP6924GS-Z is available in Cut Tape (CT) and Digi-Reel® packaging configurations, which are standard tape-and-reel formats for automated assembly processes.

Q: Do these parts require different PCB layouts or thermal management?

A: Both parts share the identical 8-SOIC package footprint (0.154" width, 3.90mm). PCB layout compatibility is assured. Thermal management requirements are not specified in the provided parameters and should be verified against detailed datasheets for specific application conditions.

Q: What compliance certifications apply to these parts?

A: Both the MP6924AGS-Z and MP6924GS-Z are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is rated at MSL 2 with a 1-year floor life rating.
