MP6924GS Equivalent & Substitute Parts

Part Overview

The MP6924GS is a secondary-side controller IC for power supply applications, specifically designed for synchronous rectifier control in isolated power conversion topologies. Manufactured by Monolithic Power Systems Inc., this component operates with a supply voltage range of 4.2V to 35V and is packaged in an 8-SOIC surface-mount configuration. The device maintains Active product status with ROHS3 compliance and MSL 2 rating.

Substitute parts become necessary when the primary component faces supply constraints, lead time extensions, or when design flexibility permits functional alternatives that meet the same electrical and mechanical requirements within the allowed parameter specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP6924GS is determined by the following critical parameters:

• Functional Category: Power Management (PMIC) classification
• Application Type: Secondary-side controller or power supply sequencer functionality
• Mounting Technology: Surface mount capability
• Supply Voltage Compatibility: Operating range must accommodate the system voltage requirements
• Current Consumption: Supply current specifications must be compatible with power budget constraints
• Regulatory Compliance: ROHS3 and REACH compliance status
• Package Compatibility: Physical dimensions and pin configuration must permit PCB layout substitution

The identified substitute ADM6819ARJZ-REEL7 qualifies based on its Power Management (PMIC) category classification, Active product status, ROHS3 compliance, and surface-mount packaging. However, critical differences exist in supply voltage range (0.9V ~ 5.5V versus 4.2V ~ 35V), current consumption (350 µA versus 16 mA), and package form factor (SOT-23-6 versus 8-SOIC).

Parameter Comparison

Engineering Selection Recommendations

Both the MP6924GS and ADM6819ARJZ-REEL7 maintain Active product status with ROHS3 compliance and REACH unaffected designation, establishing baseline regulatory compatibility. The MP6924GS operates within a wide supply voltage range (4.2V ~ 35V) suitable for diverse power supply architectures, while the ADM6819ARJZ-REEL7 is constrained to 0.9V ~ 5.5V operation.

Selection between these components must be based on the specific supply voltage requirements of the target application. The MP6924GS supports higher voltage rails typical of secondary-side controller implementations in isolated topologies. The ADM6819ARJZ-REEL7, classified as a power supply sequencer, addresses lower voltage supply sequencing applications and exhibits significantly lower supply current consumption (350 µA versus 16 mA).

Package form factor differences (8-SOIC versus SOT-23-6) require PCB layout redesign and may impact thermal management characteristics. Moisture sensitivity level differences (MSL 2 versus MSL 1) affect storage and handling requirements, with the ADM6819ARJZ-REEL7 offering extended shelf life capability.

Frequently Asked Questions (FAQ)

Q: Can the ADM6819ARJZ-REEL7 directly replace the MP6924GS on an existing PCB?

A: Direct PCB replacement is not feasible. The ADM6819ARJZ-REEL7 uses SOT-23-6 packaging while the MP6924GS uses 8-SOIC packaging. Pin counts and physical dimensions differ, requiring PCB layout modification. Additionally, functional differences between a secondary-side controller and a power supply sequencer may affect circuit operation.

Q: What are the voltage compatibility constraints for substitution?

A: The MP6924GS operates from 4.2V to 35V supply voltage. The ADM6819ARJZ-REEL7 operates from 0.9V to 5.5V. Substitution is only viable in applications where the system supply voltage falls within the 4.2V to 5.5V overlap range. Applications requiring operation above 5.5V cannot use the ADM6819ARJZ-REEL7.

Q: How do the current consumption specifications affect system design?

A: The MP6924GS draws 16 mA supply current, while the ADM6819ARJZ-REEL7 draws 350 µA. In battery-powered or low-power applications, the ADM6819ARJZ-REEL7 offers significant power consumption advantage. In high-current supply applications, the MP6924GS current specification must be accommodated within the power budget.

Q: What compliance considerations apply to both parts?

A: Both components are ROHS3 compliant and REACH unaffected, establishing equivalent regulatory status for most industrial and commercial applications. The MP6924GS carries MSL 2 rating (1-year shelf life), while the ADM6819ARJZ-REEL7 carries MSL 1 rating (unlimited shelf life), affecting storage and handling protocols.

Q: Are these parts functionally equivalent?

A: No. The MP6924GS is a secondary-side controller for isolated power conversion, while the ADM6819ARJZ-REEL7 is a power supply sequencer. These represent different functional categories within power management. Substitution requires confirmation that the target application requirements align with the substitute part's functional specification.
