Key Parameters

Substitute Part Grouping Explanation

Substitution of the SD2933-03 RF MOSFET is determined by strict alignment of the following critical parameters:

Package Compatibility: Both the main part and substitute must use the M177 package to ensure mechanical and thermal compatibility with existing PCB layouts and heat dissipation requirements.

Manufacturer Consistency: STMicroelectronics manufactures both the original and substitute part, ensuring design continuity and supply chain reliability.

Base Product Number: Both parts share the SD2933 base product number, indicating they are part of the same product family and design lineage.

Regulatory Compliance: Both parts maintain ROHS3 compliance, REACH Unaffected status, and identical MSL ratings (1 - Unlimited), ensuring no additional handling or storage requirements are introduced.

Electrical Characteristics: The substitute part maintains the same N-Channel MOSFET technology and M177 package configuration as the original part.

The SD2933-03W represents an active product variant within the same family, providing a direct path for component replacement where the obsolete SD2933-03 is no longer available.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Component Replacement: The SD2933-03W is the direct substitute for the obsolete SD2933-03. Both parts are manufactured by STMicroelectronics and share identical package specifications (M177), regulatory compliance status (ROHS3, REACH Unaffected), and handling requirements (MSL 1).

Product Status Consideration: The SD2933-03W maintains active product status, ensuring continued availability and supply chain support. Selection of the SD2933-03W eliminates the risk of future component unavailability associated with the obsolete SD2933-03.

Regulatory and Compliance Alignment: Both parts maintain identical ROHS3 compliance, REACH Unaffected designation, and export classification (EAR99), ensuring no additional regulatory documentation or supply chain modifications are required during substitution.

Packaging and Handling: The SD2933-03W is supplied in Tray packaging, which is standard for high-volume production environments. MSL rating of 1 (Unlimited) indicates no moisture sensitivity restrictions for either part, simplifying storage and handling procedures.

Frequently Asked Questions (FAQ)

Q: Can the SD2933-03W be used as a direct replacement for the SD2933-03?

A: Yes. Both parts share the M177 package, identical MOSFET technology classification, and equivalent regulatory compliance status. The SD2933-03W is the active product variant within the SD2933 family and serves as the direct substitute for the obsolete SD2933-03.

Q: What is the primary reason for substituting the SD2933-03?

A: The SD2933-03 is classified as obsolete, meaning it is no longer manufactured or supported by STMicroelectronics. The SD2933-03W provides continuity of supply as an active product within the same family.

Q: Are there any differences in package handling between the SD2933-03 and SD2933-03W?

A: Both parts have identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited), indicating no moisture sensitivity restrictions. The SD2933-03W is supplied in Tray packaging, which is standard for production environments.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the SD2933-03 and SD2933-03W are ROHS3 compliant, REACH Unaffected, and classified under the same export control designation (EAR99) and HTSUS code (8541.29.0095).

Q: What parameters determine substitution eligibility for RF MOSFET components in the SD2933 family?

A: Substitution is determined by package compatibility (M177), manufacturer consistency (STMicroelectronics), base product number alignment (SD2933), and regulatory compliance equivalence (ROHS3, REACH, MSL). Electrical performance parameters are secondary to these primary substitution criteria.

Q: Is the SD2933-03W the only substitute available for the SD2933-03?

A: Based on the provided data, the SD2933-03W is the identified substitute within the SD2933 product family. Both parts are manufactured by STMicroelectronics and share the M177 package specification.
