Key Parameters

Substitute Part Grouping Explanation

Substitution of the PBLS2003S,115 is evaluated based on the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Transistor configuration (pre-biased BJT type and quantity)
• Maximum collector current ratings for both transistor elements
• Collector-emitter breakdown voltage specifications
• Base and emitter-base resistor values
• Maximum power dissipation capability
• Transition frequency performance
• DC current gain (hFE) characteristics

Mechanical Compatibility Criteria:

• Surface mount packaging format
• Pin count and footprint compatibility
• Supplier device package designation

Compliance & Status Criteria:

• RoHS3 compliance status
• Moisture sensitivity level
• Product availability and active status

The PBLS2023D,115 qualifies as a manufacturer-recommended substitute based on matching electrical parameters within acceptable operational ranges and maintaining surface mount compatibility, despite differences in package form factor and transistor configuration polarity.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The PBLS2003S,115 is classified as Obsolete, making the PBLS2023D,115 the appropriate substitute for ongoing procurement. The substitute part carries Active product status, ensuring long-term availability and continued manufacturer support.

Compliance Alignment: Both parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental and regulatory compatibility in manufacturing and deployment environments.

Electrical Performance: The PBLS2023D,115 demonstrates superior transition frequency performance (130MHz versus 100MHz), supporting applications requiring higher-speed switching characteristics. However, the substitute part exhibits reduced maximum power dissipation (760mW versus 1.5W) and lower secondary transistor collector current rating (1.8A versus 3A). These differences require evaluation against specific application power budgets and current requirements.

Packaging Transition: The substitute part transitions from 8-SO to 6-TSOP packaging. This reduction in pin count and package footprint necessitates PCB layout modification and assembly process adjustment. Design teams must verify mechanical compatibility with existing board designs and manufacturing equipment capabilities.

Frequently Asked Questions (FAQ)

Q: Can the PBLS2023D,115 directly replace the PBLS2003S,115 without circuit modification?

A: Direct replacement requires evaluation of three factors: (1) PCB footprint compatibility—the 6-TSOP package differs from the 8-SO package, requiring layout redesign; (2) transistor configuration—the substitute uses dual PNP configuration versus the original NPN/PNP combination, affecting circuit polarity and biasing; (3) power dissipation—the reduced 760mW rating versus 1.5W must be verified against application thermal requirements.

Q: What are the key electrical differences between these parts?

A: The PBLS2023D,115 provides higher transition frequency (130MHz versus 100MHz) but lower maximum power dissipation (760mW versus 1.5W) and reduced secondary transistor current rating (1.8A versus 3A). Collector-emitter breakdown voltages and base resistor values remain identical.

Q: Are both parts RoHS compliant?

A: Yes. Both the PBLS2003S,115 and PBLS2023D,115 are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental qualification.

Q: What manufacturing considerations apply to the package transition?

A: The transition from 8-SO to 6-TSOP packaging requires PCB redesign for footprint compatibility, potential requalification of assembly processes, and verification of pick-and-place equipment capability for the smaller package format.

Q: Is the PBLS2023D,115 available for new designs?

A: Yes. The PBLS2023D,115 carries Active product status, confirming current manufacturer production and availability for both replacement and new design applications.
