Key Parameters

Substitute Part Grouping Explanation

Substitution of the BDW93CPWD is based on the following critical parameters that must align across equivalent parts:

Primary Substitution Criteria:

• Transistor Type: NPN configuration
• Voltage Rating: 100 V collector-emitter breakdown voltage (maximum)
• Package: TO-220-3 through-hole mounting
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Compliance: REACH Unaffected status

The BDW93C from STMicroelectronics satisfies these core requirements. Both parts share the BDW93 base product number, indicating a common design lineage. The BDW93C is an active product with enhanced current handling capability (12 A maximum collector current) and includes Darlington configuration, which provides superior current gain characteristics while maintaining the 100 V voltage rating and TO-220 package specification.

Engineering Selection Recommendations

BDW93C (STMicroelectronics) as Primary Substitute:

The BDW93C is the appropriate substitute for the obsolete BDW93CPWD. Both components maintain identical voltage ratings (100 V collector-emitter breakdown) and package specifications (TO-220 through-hole). The BDW93C holds active product status, ensuring ongoing availability and supply chain continuity. Both parts are REACH Unaffected and carry MSL Level 1 classification, meeting environmental and moisture sensitivity requirements.

The BDW93C incorporates Darlington configuration, which increases DC current gain and collector current capacity (12 A maximum) compared to the standard BDW93CPWD specification. This enhancement provides additional design margin in applications requiring higher current handling. The component is RoHS3 compliant, supporting modern manufacturing and environmental standards.

Selection of the BDW93C eliminates obsolescence risk while maintaining electrical compatibility within the specified 100 V voltage class and TO-220 package form factor.

Frequently Asked Questions (FAQ)

Q: Can the BDW93C directly replace the BDW93CPWD in existing designs?

A: Yes. Both components share the BDW93 base product number, identical 100 V voltage rating, and TO-220 package specification. The BDW93C is electrically compatible for applications designed around the BDW93CPWD. The Darlington configuration of the BDW93C provides enhanced current gain, which is beneficial in most switching and amplification applications.

Q: What is the primary reason for substituting the BDW93CPWD?

A: The BDW93CPWD is classified as obsolete. The BDW93C from STMicroelectronics is an active product with confirmed ongoing availability, ensuring long-term supply chain reliability and design continuity.

Q: Are there packaging differences between these parts?

A: Both components use TO-220 through-hole packages suitable for identical PCB layouts and thermal management approaches. The BDW93C is specified as TO-220-3, which is the standard three-lead configuration for this package type.

Q: Do these parts have the same moisture sensitivity requirements?

A: Yes. Both the BDW93CPWD and BDW93C carry MSL Level 1 (Unlimited) classification, indicating no moisture sensitivity constraints during storage or handling.

Q: Is the BDW93C compliant with current environmental standards?

A: Yes. The BDW93C is RoHS3 compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the significance of the Darlington configuration in the BDW93C?

A: The Darlington configuration provides higher DC current gain (750 minimum at specified conditions) and supports higher collector current (12 A maximum) compared to standard BJT configurations. This allows the BDW93C to operate effectively in applications requiring substantial current amplification or switching capacity while maintaining the same voltage rating and package form factor.
