Key Parameters

Substitute Part Grouping Explanation

Substitution for the MP6924GS-Z is determined by functional category alignment and electrical parameter compatibility. The primary substitute identified is the DM7308G-65512-B1, which operates within the power management controller domain. However, this substitute operates at a different voltage supply range (3V ~ 3.6V versus 4.2V ~ 35V) and uses a different package format (64-QFN versus 8-SOIC), indicating it addresses similar functional requirements but with distinct electrical and mechanical specifications.

The secondary substitute, TEA1716T/1,518, is a PFC controller operating in discontinuous conduction mode with a significantly different voltage supply specification (70 ~ 276 VAC), representing a different application class within power management.

Substitution logic is based on:

• Functional category (Power Management PMIC)
• Supply voltage compatibility range
• Current supply requirements
• Package and mounting compatibility
• RoHS and compliance certifications

Parameter Comparison

Engineering Selection Recommendations

The MP6924GS-Z is no longer recommended for new designs. For legacy system support and maintenance, the DM7308G-65512-B1 and TEA1716T/1,518 are listed as manufacturer-identified substitutes, both carrying active product status and full RoHS3 compliance.

Selection between substitutes depends on application-specific voltage requirements. The DM7308G-65512-B1 operates at lower voltage levels (3V ~ 3.6V) and requires PCB layout modifications due to package format change from 8-SOIC to 64-QFN. The TEA1716T/1,518 is designed for AC input applications (70 ~ 276 VAC) and represents a different functional class within power management.

Both substitutes maintain RoHS3 compliance and EAR99 export classification consistent with the original part. Moisture sensitivity levels differ, with substitutes rated at MSL 3 (168 Hours) compared to the original MSL 2 (1 Year), requiring adjusted handling and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the DM7308G-65512-B1 directly replace the MP6924GS-Z on existing PCBs?

A: No. The DM7308G-65512-B1 uses a 64-QFN package versus the 8-SOIC package of the MP6924GS-Z. PCB layout redesign is required. Additionally, the voltage supply range differs (3V ~ 3.6V versus 4.2V ~ 35V), necessitating circuit topology evaluation.

Q: What is the functional difference between the MP6924GS-Z and TEA1716T/1,518?

A: The MP6924GS-Z is a secondary-side synchronous rectifier controller for isolated power supplies. The TEA1716T/1,518 is a PFC controller for AC input applications. These serve different functional roles within power management systems.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both DM7308G-65512-B1 and TEA1716T/1,518 are ROHS3 compliant, matching the compliance status of the original MP6924GS-Z.

Q: What are the moisture sensitivity implications of substitution?

A: The original MP6924GS-Z carries MSL 2 (1 Year) rating. Both substitutes are rated MSL 3 (168 Hours), requiring stricter moisture control during storage and handling. Components must be used within 168 hours of bag opening under controlled humidity conditions.

Q: Is the MP6924GS-Z still available for purchase?

A: The MP6924GS-Z is classified as not for new designs. Inventory availability is limited to existing stock. For new applications, active substitute parts should be evaluated.
